Abstract:

With scaling of ULSI devices, the process temperatures are continuously lowered. The oxide films, which were deposited at low temperature, show fast etching rates during wet etching compared to high temperature films. Also, the etch rates differ largely from other film deposition conditions. In order to overcome these etch rate differences during surface preparation, dry cleaning processes had been introduced where the etch selectivity of the soft oxide films to the thermal oxide are very similar, regardless of the film deposition conditions and the deposition temperature.

Abstract:

Inductively coupled plasma (ICP) etching of Ge with high selectivity over Si and anisotropic etched profiles using CF4, HBr, SF6, and Cl2 reactive gases has been studied. Because pressure and biased power should be the most important parameters to drive selectivity and etch profile, they were varied from 4 to 50 mTorr and from 0 to 50 W, respectively, so as to investigate their influence on process. Total gas flow (100 sccm) and source power (350 W) were initially held constant. Selectivity greater than 100:1 of Ge over Si was achieved using 100 % Cl2 etch gas at 50 mTorr and zero bias power b

Abstract:

Patterning of NiO/Ga2O3 heterojunctions requires the development of selective wet and dry etch processes. Solutions of 1:4 HNO3 :H2O exhibited measurable etch rates for NiO above 40 °C and activation energy for wet etching of 172.9 kJ.mol-1 (41.3 kCal.mol-1, 1.8 eV/atom), which is firmly in the reaction-limited regime. The selectivity over β-Ga2O3 was infinite for temperatures up to 55°C. The strong negative enthalpy for producing the etch product Ga(OH)4 suggests that HNO3-based wet etching of NiO occurs via the formation and dissolution of hydroxides.

The subject of this report is the characterization of plasma etch residues after a metal etch process with Cl2/BCl3 etch gases. One of the interactive factors in the removability of the residues is the photo-mask removal process (DSQ). Depending on the DSQ process the molecular structure of the residues will differ. For our findings, we used laser spectroscopy and Fourier-transformed infrared spectroscopy to obtain information about the degree of the cross-linking of the molecular structure of residues in a post-metal etch cleaning process.

In this study, the SiO2 etch characteristics of perfluorocarbon such as C4F8, C5F8, and C7F8 were investigated using inductively coupled plasmas (ICPs) to study the effect of a high C/F ratio on the etch characteristics of SiO2 for the ICP. The SiO2 rates and etch selectivities over Si3N4 and amorphous carbon layer (ACL) were measured by using the mixtures of Cx(x = 4, 5, 7)F8/Ar/O2. The higher C/F ratio of perfluorocarbon showed lower SiO2 etch rate but exhibited higher etch selectivities over Si3N4 and ACL due to the higher C2 while keeping the similar F in the plasma as observed by optical

Abstract:

TSV (Through Silicon Vias) are usually formed and deposited as blind vias. As a last stage, vias are opened by thinning of the back side of the wafer. While the bulk of the silicon can be removed by both wet and dry methods, the final step of the “Via Reveal” process is predominantly performed by wet etch. Two commonly used types of etching solutions are anisotropic alkaline etch (KOH, TMAH, etc.) and isotropic etch (HF/HNO3, etc.). Etch rate, uniformity, and product characteristics strongly depend on the composition of solution: both original compounds and reaction products. This presentation

Abstract:

In this work, we demonstrate a deep mesa etch design for efficient edge field termination in β-Ga2O3 Schottky barrier diodes (SBDs). The proposed design enabled parallel plate fields higher than 4.1 MV/cm with negligible change to the device ON characteristics. The effect of BCl3/Cl2-based dry etch on (100) and (010) etched vertical sidewalls is also analyzed. A remarkable anisotropy in depletion was observed for etch along (100) and (010) sidewalls. This work provides insight into the impact of etching on n-type Ga2O3 and shows a promising method to realize efficient field termination for hig

Abstract:

Amorphous carbon hard mask (ACHM) films are widely used as etching hard masks in 3D-NAND flash memory, which has put forward higher requirements in the film deposition rate, film transparency, uniformity, and selective etching. In this work, the ACHM film processing is engineered and optimized by comparatively studying acetylene (C2H2) and propylene (C3H6) as carbon sources at the different temperatures of 300 °C, 350 °C and 400 °C. By increasing the deposition temperature, the deposition rate, non-uniformity, and dry etch rate of ACHM are improved at the penalty of a slightly increased extinc

Abstract:

This is the first demonstration of sidewall slope control of InP via holes with an etch depth of more than 10 μm for 3D integration. The process for the InP via holes utilizes a common SiO2 layer as an InP etch mask and conventional inductively coupled plasma (ICP) etcher operated at room temperature and simple gas mixtures of Cl2/Ar for InP dry etch. Sidewall slope of InP via holes is controlled within the range of 80 to 90 degrees by changing the ICP power in the ICP etcher and adopting a dry-etched SiO2 layer with a sidewall slope of 70 degrees. Furthermore, the sidewall slope control of th

Abstract:

In semiconductor wafer fabrication, etching refers to the process of removing unwanted material from wafer surface through a subtractive process. Metal etching is most commonly used in the patterning of metal films for interconnects by establishing specific connection and conduction paths and can be classified by dry etching, de-plating and dissolution of the layers on various substrates such as silicon, SiO2, Si3N4, GaAs, germanium, and sapphire. Dry etching is used to produce very precise etching of vertical channels or vias forming the device features or lines which make up the conductive p

Abstract:

ABSTRACTIndium Phosphide (InP) based multilayer structures are becoming increasingly important in the semiconductor industry with optoelectronic applications being the main growth area. Mesa type structures with finely controlled width and etch angle, often form the building blocks for many of these photonic devices. Traditional wet etching techniques have often proved to be inadequate for the required anisotropie removal of material. This paper presents the results of etching semi-insulating InP (100) using a combination of an Argon ion beam and a reactive gas, CCl2F2 (Freon 12). It was found

Abstract:

ABSTRACTThe wet chemical etching rates of InGaP in H3 PO4:HCL:H2O mixtures have been systematically measured as a function of etch formulation and are most rapid (-1 μm · min−1) for high HCl compositions. The etch rate, R, in a 1:1:1 mixture is thermally activated of the form R ∝ e−Ea/kT, where Ea = 11.25 kCal · mole−1. This is consistent with the etching being reaction-limited at the surface. This etch mixture is selective for InGaP over GaAs. For chlorine-based dry etch mixtures (PCl3 /Ar or CCl2 F2 /Ar) the etching rate of InGaP increases linearly with DC self-bias on the sample, whereas CH

Abstract:

AbstractFabrication of group-III nitride devices relies on the ability to pattern features to depths ranging from ∼1000 Å to > 5 μm with anisotropic profiles, smooth morphologies, selective etching of one material over another, and a low degree of plasma-induced damage. In this study, GaN etch rates and etch profiles are compared using reactive ion etch (RIE), reactive ion beam etching (RIBE), electron cyclotron resonance (ECR), and inductively coupled plasma (ICP) etch systems. RIE yielded the slowest etch rates and sloped etch profiles despite dc-biases > −900 V. ECR and ICP etching yi

AbstractTwo techniques for dry etching of sol-gel lead zirconate titanate (PZT 52/48) thin films were investigated: reactive ion etching and argon ion milling. Etched profiles were characterized by scanning electron microscopy. For reactive ion etching, a parallel plate etcher was used with HC2ClF4, an environmentally safe etch gas, in a process described by other researchers. Etch rates were measured and compared as a function of electrode shield material (ardel, graphite, alumina) and RF input power (100 to 500 W). These etch rates varied from 10 to 100 nm/min.
