Full text

Abstract:

A simple and practical method is described for determining the residual stress in vapor deposited thin films that are less than 1000 Å in thickness. The method relies on the evaporation of thin films onto prefabricated micro-cantilever beams of SiO2. The vertical deflection at the end of the beam is measured using an optical microscope to determine the average film stress with a resolution of 25 MPa. Calculations show that the vapor deposition of metal films onto these beams does not induce significant heating, so the thermal component of residual film stress is minimal. The micro-cantilever technique is used to measure the film stress in 500 Å films of Al, Ti, Pt, Au, Ni, and Ge. These measured values are compared to similar measurements reported in the literature.

Abstract:

It is known that thin films of polycrystalline silicon, deposited under the right conditions, can be permeable to HF-based etching solutions. While these films offer unique capabilities for microfabrication, both the poor reproducibility of the permeable film properties and the lack of a detailed physical understanding of the material have limited their application. This work provides a methodical study of the relationship between process, microstructure, and properties of permeable polycrystalline silicon thin films. It is shown that the permeability is a result of small pores, on the order of 10 nm, between the 100–200-nm hemispherical grains characteristic of the permeable film morphology. This morphology occurs only in nearly stress-free films grown in a narrow temperature range corresponding to the transition between tensile and compressive film growth regimes. This result strongly suggests that the monitoring of residual film stress can provide the process control needed to reliably produce permeable films. A simple kinetic model is proposed to explain the evolution of the morphology of the permeable films.

Abstract:

Composition, structure, and optical properties of films formed on the surface of niobium during laser processing are presented. Two modes of laser oxidation of niobium are empirically determined. The first mode, using single-pass laser processing, create the blue shade oxide film, the second mode, using multipass laser processing, forms the green shade oxide film. The optical contrast, determined as a difference of reflection coefficients, in the infrared spectrum of the blue oxide film is equal to 0.2 and the green oxide film forms the contrast equal to 0.5. It was found that the niobium blue shade oxide films, obtained after laser processing, has stoichiometry NbO and the green oxide film has stoichiometryNbO2.

Abstract:

Stoichiometric CaMoO4 thin film was successfully fabricated based on chemical solution processing. The thin films were deposited on Si(100) substrates by means of the spin-coating technique. X-ray diffraction reveals that the CaMoO4 thin film prepared are pure and well crystalline thin films. Atom Force Microscope photographs indicate that the film prepared possesses a homogeneous and dense surface morphology. The average grain size of the films was 40–50 nm, and the root-mean-square (RMS) of the surface roughness and the average surface roughness of the film measured were 2.161 nm and 1.726 nm respectively. The photoluminescent properties of calcium molybdate thin film under ultraviolet light excitation were systematically measured from 12 K to room temperature and a green emission band of the films were observed. The results of present work confirm that the chemical solution processing is a promising technology on the fabrication of CaMoO4 thin film.

Abstract:

Four different plastics were tested: potato starch based plastic (TPS-P)–BIOPLAST GF 106/02; corn starch based plastic (TPS-C)–BioComp BF 01HP; polylactic acid (polylactide) plastic (PLA)—BioComp BF 7210 and low density polyethylene, trade name Malen E FABS 23-D022; as a petrochemical reference sample. Using the blown film extrusion method and various screw rotational speeds, films were obtained and tested, as a result of which the following were determined: breaking stress, strain at break, static and dynamic friction coefficient of film in longitudinal and transverse direction, puncture resistance and strain at break, color, brightness and gloss of film, surface roughness, barrier properties and microstructure. The biodegradable plastics tested are characterized by comparable or even better mechanical strength than petrochemical polyethylene for the range of film blowing processing parameters used here. The effect of the screw rotational speed on the mechanical characteristics of the films obtained was also demonstrated. With the increase in the screw rotational speed, the decrease of barrier properties was also observed. No correlation between roughness and permeability of gases and water vapor was shown. It was indicated that biodegradable plastics might be competitive for conventional petrochemical materials used in film blowing niche applications where cost, recyclability, optical and water vapor barrier properties are not critical.

Abstract:

Sol-gel Sr2Nb2O7 thin films were deposited on Si(100) and Pt-coated Si substrates for the first time by spin-coating. The Sr2Nb2O7 precursor solution was prepared from strontium metal dissolved in 2-methoxyethanol, acetylacetone, and niobium ethoxide. The formation of phase pure Sr2Nb2O7 occurred via an intermediate perovskite phase of composition close to Sr0.82NbO3. Crack-free Sr2Nb2O7 films of ∼0.4 μm thickness were deposited on these substrates using a single-coating followed by heat treatment at 850 °C for 12 h. SEM microstructure and thin film XRD results indicated the deposition of a grain-oriented film on the Pt-coated Si substrate. The room temperature dielectric constant and the loss values of the film measured at 10 kHz are 45 and 0.045, respectively.

Abstract:

The surface characteristics and depth profile of free-standing polycrystalline diamond films chemically etched from silicon substrates have been studied using monochromatic X-ray photoelectron spectroscopy and Auger electron spectroscopy. Two different processes for isolating the diamond films from the silicon substrates have been performed. The isolated/annealed-diamond film was prepared by rapid thermal processing (RTP) of the diamond-on-silicon film at a temperature of 800°C before chemically etching the diamond film from the silicon substrate. The annealed/isolated film was prepared by first chemically etching the diamond film from the silicon substrate, and then subjecting the stand-alone film to RTP. The qualities of the film on the top faces were improved for both the isolated/annealed-diamond and annealed/isolated-diamond films as verified by Raman spectroscopy. XPS analysis revealed different oxidation characteristics on the top and bottom faces of the isolated/annealed-diamond and annealed/isolated-diamond films. Silicon was detected on the bottom surfaces. A higher silicon and oxygen intensity was observed on the isolated/annealed diamond films compared to the annealed/isolated films. This can be due to the facilitated thermal diffusion of silicon into the grain boundaries during the initial RTP step in the preparation of the isolated/annealed-diamond film.

Abstract:

The aim of this study was to compare the sensitometric properties of Insight and Ektaspeed Plus radiographic films manually and automatically processed using fresh and depleted chemical solutions. Ten sets of each type of film were obtained (1 set = 5 films), 5 sets being manually processed and 5 sets being automatically processed. A total of 100 films (50 Ektaspeed Plus and 50 Insight film) were exposed and developed. The first two sets of each film type were developed in fresh chemicals (one set per each type of processing), on the first day of the experiment. The other sets were processed in the same progressively depleted solutions once a week until the end of experiment, which was completed within 4 weeks. Characteristic curves were constructed to compare the sensitometric properties of the films: contrast, latitude and speed. Processing solution depletion had different effects on manually and automatically developed films, which was confirmed by the changes in the form of the characteristic curves in the third week of the automatic processing and fourth week of the manual processing. Ektaspeed Plus showed 11% reduction in contrast values for manual processing and 53% for automatic processing, while Insight contrast values showed a reduction of 25% and 59%, respectively. Insight film, however, showed lesser loss of speed and lesser increase of latitude than Ektaspeed Plus. In conclusion, chemical depletion in automatic film processing was faster than in manual developing. In depleted chemicals, both types of films had an increase in latitude values and a decrease in speed and contrast. Insight was more resistant than Ektaspeed Plus to decrease in speed and latitude when processed using older chemicals, whereas contrast in Ektaspeed Plus was comparatively more stable.

Abstract:

Rigid network structures of nanoporous organic polymers provide high porosity, which is beneficial for applications such as gas sorption, gas separation, heterogeneous (photo)catalysis, sensing, and (opto)electronics. However, the network structures are practically insoluble. Thus, the processing of nanoporous polymers into nanoparticles or films remains challenging. Herein, we report that nanoporous polymers made via a Knoevenagel-like condensation can be easily processed into nanoparticles (115.7 ± 40.8 nm) or a flawless film by using liquid amines as a solvent at elevated temperatures. FTIR spectra revealed that the carboxyl groups in the nanoporous polymers act as reactive sites for amines, forming new functionalities and spacing the polymeric chains to be dissolved in the liquid amines. The processed film was found to be CO2-philic despite the low surface area, and further able to be transformed into a fine carbon film by thermal treatment.

Abstract:

Purpose: X-ray film processing is associated with pollution from photo chemicals and from the water used to rinse the film. We tested a new processing system that was aimed at reducing both environmental pollution and costs through the use of solid photo chemicals and recirculation of the rinsing water Material and Methods: Before and after the installation of new mixers for the solid chemicals and a system for recirculating the rinsing water, we measured: water consumption, processor function quality, image quality, archivability, and the waste-silver content in the rinsing water Results: After the installation of a simple system for recirculating the rinsing water, there was an 88% reduction in water and film consumption as shown in the amount of water/m2film that was used. At the same time, the release of silver-contaminated rinsing water directly into the sewers was stopped. Image quality remained unchanged. Archivability was assessed at more than 100 years. The solid photo chemicals and specially designed mixers proved efficient and provided a stable image quality of high standard. It was thus possible to reduce the risk of pollution from the transportation, storage and handling of liquid chemicals Conclusion: A simple recirculation system for the rinsing water would significantly reduce water consumption and eliminate contamination of the environment by silver. The on-site preparation of photo chemicals proved viable and reduced the costs of film processing

Abstract:

A research on the process of forming an image on a radiographic film and processing techniques automatically has been done. The study was conducted using an X-ray plane Toshiba E 7239, Fil AGFA Healtcare HV Septestraat 27B2640 Mortsel and an automatic film processing "Automatic X-Ray Film Processor Model JP-33". The experimental results showed that the principle of automatic film processing is the same as the principle of film processing manually, except in automatic film processing there is no rinsing stage. Automatic film processing can save time and costs; also it can reduce the possibility of errors due to human factors.

Abstract:

For optimum fabrication and usage of Cu films, an understanding of the relationship between processing and microstructure is required. The existence of twins is another significant factor for texture development in Cu films. Texture character and strength in the Cu film is dependent on the twin boundary development that is a function of processing conditions and film thickness. In this study, determination of grain growth and texture in the sputtered and electroplated Cu films during annealing was performed for films of 100, 480 and 850 nm in thickness deposited on a Ta(25 nm)/Si wafer. The texture was measured by X-ray pole figure. The effect of film thickness on the annealing texture in the sputtered and electroplated Cu films is examined and discussed.

Abstract:

<p>Dip-coating is a conventional solution processing technology to prepare large-area films at a low cost and with cheap facilities. For semiconductor film processing, crystal orientation and thickness uniformity are the primary factors that determine the film quality and its electrical performance. These requirements are readily satisfied with the dip-coating method because the film morphology can be effectively optimized by tuning the withdrawal speed. This work optimizes the withdrawal speed for the dip-coating of patterned semiconductor films of 400×500 mm2 as well as that for film dip-coating on the whole surfaces of the substrate. For both experiment, optimized electrical mobility is achieved at the same withdrawal speed, however, the random crystal orientation of the patterned films causes a remarkable decrease in device performance.</p>

Abstract:

This article reexamines the career of Roger Jacoby (1945–1985), an abstract painter and gay liberation activist who became renowned for processing film in his darkened bathtub and for films that featured his partner, Ondine, the Andy Warhol Superstar. Through a consideration of film shorts made in the 1970s and 1980s, the article argues that Jacoby’s principal innovation was the exploration of hand-processing, which resulted in films that resembled abstract expressionist paintings in motion. Additionally, it considers hand-processing as an overlooked, albeit powerful, vehicle for expressing non-normative sexuality in American avant-garde film. It situates Jacoby alongside gay filmmakers Kenneth Anger, Gregory Markopoulos, and Jack Smith, and considers how hand-processed media can generate a “corporealized” spectator and disrupt patterns of filmic illusionism and heterosexist protocols of sexual/gender representation.

The mean diameters of nanoporous anodic aluminum oxide templates are 100 nm and 200 nm by various processing parameters of the anodization method. A molded plastic thin film nanostructure is fabricated by nanoimprinting using the AAO template as a mold. The surface properties of the molded plastic thin film are discussed using various nanoimprinting process parameters. Contact angles of the molded plastic thin film with the nanostructure exceed those without the nanostructure. The molded plastic thin films with a nanostructure and a hydrophobic surface are formed, and their contact angles exceed 90°.

Abstract:

The properties of UHMW-PE film produced by hot compression molding and films modified by acid and anti-static agent were characterized. The results showed that: a) the thickness distributing of the film which processing by calendar rolling with conventional design roller is inhomogeneity; the tensile strength was 37.22 MPa, the elongation at break was 368.00%; the transmittance increases with wavelength redshift shows short-wave absorption and long-wave transmission; initial temperature of dissociation is 320°C; the surface resistance 1010 Ω and maximum is higher than 1016 Ω. b) Acid modification the surface of UHMW-PE film moderates the surface antistatic performance. C) After modified the film with external anti-static agent, the surface resistance was around 107Ω, but anti-static properties loss rapidly after friction. If modified the film with internal anti-static agent, the surface resistance was around 1010 Ω and have a long-lasting anti-static effect.

Abstract:

Thin-film composites of BaTiO3 particles in a polymeric matrix were processed by reacting films of a titanium alkoxide, mixed with a polybutadiene-polystyrene triblock copolymer, in aqueous solutions of 1.0 M Ba(OH)2 at temperatures ranging from 60 to 90 °. After reaction, the composite films displayed distinct surface and subsurface morphologies. The film surface consisted of a continuous layer of BaTiO3 grains, the film grain size decreasing from 180 to 60 nm as the reaction temperature increased from 60 to 90 °. The subsurface growth of BaTiO3 depended on the presence of a percolating network of hydrolyzed titanium alkoxide, which enabled the reaction solution to permeate throughout the thin film. The resulting subsurface film morphology was composed of segregated regions of BaTiO3 particles dispersed throughout the polymeric matrix. The growth of subsurface BaTiO3 particles appeared to be constrained by the polymer matrix, resulting in a subsurface particle size of approximately 5 to 10 nm that was independent of the hydrothermal processing temperature. The reacted films displayed a dielectric constant ranging from 10 to 15 at room temperature and a frequency of 10 kHz.

Abstract:

Thin LiNbO3 films were prepared from polymerized sol-gel precursor solutions having various concentrations and water:alkoxide ratios in an effort to investigate the effects of these and other processing variables on the resultant film properties and microstructure. Films deposted on silicon substrates were mostly amorphous when pyrolyzed at 435°C for 30 min. Randomly oriented polycrystalline films having distinctive microstnietures were produced using longer heating times or higher temperatures. All of the films exhibited low refractive indices due to porosity, which was attributed to the low level of hydrolysis water required to produce stable polymeric precursor solutions. When single-crystal LiNbO4 was used as the substrate, epitaxial growth of the film resulted. This ideal case establishes the feasibility of producing epitaxial films via sol-gel processing. All films were characterized by transmission electron microscopy (TEM) and thin-film x-ray diffraction patterns.

Abstract:

This paper presents a characterization of a plastic extrusion process and the selected properties of three biodegradable plastic types, in comparison with LDPE (low-density polyethylene). The four plastics include: LDPE, commercial name Malen E FABS 23-D022; potato starch based plastic (TPS-P), BIOPLAST GF 106/02; corn starch based plastic (TPS-C), BioComp®BF 01HP; and a polylactic acid (polylactide) plastic (PLA), BioComp®BF 7210. Plastic films with determined geometric parameters (thickness of the foil layer and width of the flattened foil sleeve) were produced from these materials (at individually defined processing temperatures), using blown film extrusion, by applying different extrusion screw speeds. The produced plastic films were tested to determine the geometrical features, MFR (melt flow rate), blow-up ratio, draw down ratio, mass flow rate, and exit velocity. The tests were complemented by thermogravimetry, differential scanning calorimetry, and chemical structure analysis. It was found that the biodegradable films were extruded at higher rate and mass flow rate than LDPE; the lowest thermal stability was ascertained for the film samples extruded from TPS-C and TPS-P, and that all tested biodegradable plastics contained polyethylene.

Abstract:

ABSTRACTWe have investigated the fabrication of graphene by chemical vapor deposition using a conventional rapid thermal processing system with infrared heating. Graphene films were grown on the pretreated copper foil in RTP at 935-960°C at pressure of 6~7 mbar. The grown films were characterized by scanning electron microscope and Raman spectroscopy to investigate morphology of graphene. The growth of graphene was initiated by small flakes that spread rapidly covering the whole copper surface as a single-layer film in ~20 seconds. Room temperature mobility and sheet resistance extracted by transfer-length method (TLM) for the graphene film transferred onto the SiO2/Si substrate were around 1,800 cm2/Vs and 260 Ω/ð with the gate voltage, respectively.

Abstract:

Edible packaging has been successfully used for packaging of low moisture foods such as wrappers. One of the hurdles in the use of edible packaging for moisture rich foods is its ability to successfully seal the package, which is critical due to the lower strength and elastic characteristics of edible films compared to plastic based films. Three important sealing parameters, namely, adhesive concentration, pressure, and temperature during sealing, were investigated to assess sealing performance of the edible film. The edible film was prepared from blend of three polymers (sodium alginate, sodium carboxymethyl cellulose, and gelatin) based on previous research work. The seal was evaluated for seal strength and a quadric regression model to predict seal strength as a function of adhesive concentration, pressure, and temperature during sealing was established. The model was statistically significantP<0.05and an optimum combination of sealing parameters was obtained to be 24.4% adhesive concentration, 0.28 MPa pressure, and 153°C temperature. A sealing time of 1 s was used for all samples. All three factors were significant taken individually and interactions of the three factors were also significant (P<0.05or 0.10) except for the interaction between adhesive concentration and sealing temperature.
