High temperature reactive ion etching stage
WebReactive Ion etching (RIE) is the process of transferring pattering in a top mask layer (e.g. Resist) to a second bottom layer (e.g. Silicon) using a plasma of etching gases (e.g. CF4 gas). Plasma is formed when a high electric field breaks down the gas molecules to ions, neutral, and radicals. WebReactive-ion etching facilitates patterning of tin oxides, such as barium stannate (BaSnO3), at a consistent and controllable etch rate. The reactive-ion etching approach described herein ...

WebJun 7, 2004 · The reaction was carried out with a conventional plasma etching or reactive ion etching (RIE) reactor at a wide range of temperatures, e.g., room temperature to 300°C, using halogen chemistry, such as HCl, Cl 2, or HBr. The edge profile can be controlled by the process condition. Different wall profiles can be prepared.
WebEtch characteristics of ovonic threshold switch (OTS) materials composed of Ge–As–Te for a phase-change random access memory (PCRAM) has been investigated using reactive ion etching via hydrogen-based gases such as H2,CH4,NH3,CH4 +H2, and CH4 +NH3. Among the investigated hydrogen-based gases, NH3 showed the highest etching rate of about 0. ... WebDec 16, 2002 · Photoassisted electrochemical (PEC) etching of n-doped GaN layer grown on sapphire in the KOH based solution under illumination by a mercury-xenon-arc lamp is demonstrated. Smooth surfaces were obtained for a narrow range of etching conditions. It was found that this range could be extended by using etch conditions which produced …

WebOct 11, 2011 · A three stage reactive ion etching process for selectively etching p-doped polysilicon over silicon dioxide has been demonstrated using a mixture of Cl 2 and HBr. The etching speed of the etch process is 3500 Å per minute with a selectivity to photoresist of around 4:1. The overetch process developed uses pure HBr to selectively etch ...
WebDry etching of GaN has been extensively investigated using numerous plasma-based machines and sources. High etch rate (1.3 µm/min) was reported using an electron cyclotron resonance (ECR) [1].
