Abstract:

This paper analyzes data retention characteristics to determine process effects on the trap energy distribution of silicon nitride in silicon-oxide-nitride-oxide-silicon (SONOS) flash memory devices. Nitride films were prepared by low-pressure chemical vapor deposition (LPCVD) and plasma-enhanced chemical vapor deposition (PECVD). PEVCD films embedded with silicon nanocrystals (Si-NCs) were also compared. The flat band voltage shift in the programmed device was measured at high temperatures to observe the thermal excitation of electrons from the nitride traps in retention mode. The trap energy

Multi-wall carbon nanotube (MWCNT) structures were grown on cobalt catalyst layer through Plasma Enhanced Chemical Vapor Deposition (PECVD) process. Acetylene (C2H2) and hydrogen (H2) are used as precursors during the PECVD process. The morphology structures of the MWCNTs grown under different PECVD time were investigated and characterized using Scanning Electron Microscope (SEM). The effect of the PECVD time on the MWCNT growth is studied by varying the PECVD time at 45 sec and 600 sec. The morphology structures suggest that the growth rate is proportional to the PECVD time under the similar

The issue of potential-induced degradation (PID) has gained more concerns due to causing the catastrophic failures in photovoltaic (PV) modules.

Here, we focus on the modification of ARC films to realize PID-free step-by-step through three delicate experiments. Firstly, the ARC films deposited by direct plasma enhanced chemical vapor deposition (PECVD) and by indirect PECVD were investigated. The results showed that the efficiency degradation of

The hydrophilic properties of amorphous TiOx films prepared by different methods, e.g., radio frequency (rf) sputtering and plasma-enhanced chemical vapor deposition (PECVD), were studied.

The best hydrophilicity was realized with the PECVD amorphous film having distorted Ti–O bonds due to a large amount of OH groups. These characteristics of the PECVD amorphous film suggest that such a low-density film including distorted Ti–O bonds could increase the photoenhancement efficiency by ultraviolet radiation.

Abstract:

Passivating contacts are becoming a mainstream option in current photovoltaic industry due to their ability to provide an outstanding surface passivation along with a good conductivity for carrier collection. However, their integration usually requires long annealing steps which are not desirable in industry. In this work we study PECVD as a way to carry out all deposition steps: silicon oxide (SiOx), doped polycrystalline silicon (poly-Si) and silicon nitride (SiNx:H), followed by a single firing step. Blistering of the poly-Si layer has been avoided by depositing (p+) microcrystalline silico

Abstract:

The use of plasma in semiconductor fabrication processes has been continuously increasing because of the miniaturization of semiconductor device structure, and plasma enhanced chemical vapor deposition (PECVD) has become a major process in thin film deposition. As a consequence, plasma diagnosis has become crucial during the deposition process, but the lack of in situ plasma monitoring sensors requires further development of existing in situ sensors, such as the Langmuir probe and optical emission spectroscopy (OES), for in situ plasma process monitoring. In this study, electrically equivalent

The antibacterial activity of graphene nanostructures (GrNs) on glass (G) and nickel (Ni) substrates against Escherichia coli ATCC 35218 (Gram-negative) and Staphylococcus aureus ATCC 25923 (Gram-positive) has been researched in this study. GrNs have been synthesized via two different methods, namely, chemical vapor deposition (CVD) and plasma enhanced chemical vapor deposition (PECVD). While the antibacterial effect of CVD-grown graphene nanosheets has been examined according to the number of layers (monolayer/1–2 layers/2–3 layers), the effect of PECVD grown Gr nanowalls on G substrates has

Abstract:

Molybdenum disulfide (MoS2) has attracted considerable attention as a promising electrocatalyst for the hydrogen evolution reaction (HER). However, the catalytic HER performance of MoS2 is significantly limited by the few active sites and low electrical conductivity. In this study, the growth of multiorientated polycrystalline MoS2 using plasma-enhanced chemical vapor deposition (PECVD) for the HER is achieved. The MoS2 is synthesized by sulfurizing a sputtered pillar-shaped Mo film. The relatively low growth temperature during the PECVD process results in multiorientated MoS2 with an expanded

Abstract:

Silicon nitride (SiN) films deposited via plasma-enhanced chemical vapor deposition (PECVD) exhibit tunable tensile stress, which is critical for various microelectronic and optoelectronic applications. In this paper, the effects of silane (SiH4) flow rate during PECVD deposition, ultraviolet (UV) curing, and layered deposition on the tensile stress of SiN films are mainly investigated. The results reveal that increasing the SiH4 concentration raises hydrogen incorporation, which modifies internal stress dynamics. UV curing significantly increases tensile stress by breaking N-H and Si-H bonds,

This optimization will eventually allow a-SiC:H to be used as an ideal insulation, passivation and protection layer for thin and biocompatible al

SiO2 is a crucial material in silicon-based semiconductor devices, where efficient thermal management is essential. Reliable thermal conductivity for SiO2 grown by plasma enhanced chemical vapor deposition (PECVD) at different deposition temperatures remains lacking. In this study, we measured the thermal conductivity of PECVD-grown SiO2 to be 1.11–1.13 W m−1 K−1 at room temperature, with minimal dependence on the PECVD deposition temperature. Notably, PECVD-grown SiO2 exhibits higher thermal conductivity than SiO2 grown by other low-temperature process techniques. Moreover, we propose a revis

ABSTRACTPlasma enhanced chemical vapor deposited tungsten nitride (PECVD-W67N33) thin film has been proposed as a diffusion barrier. The resistivity and lattice constant of PECVD-W67N33 are 110-28 μΩ-cm and 4.134 Å, respectively and this film has compressive stress of 2.6 × 1010 dyne/cm2. Thermal stability of PECVD-W67N33 as a diffusion barrier reveals that the interdiffusions between Al or W and Si substrate can be prevented by N interstitial atoms in fcc-W2N grains and grain boundaries.
