Web3. Etch chamber (Main chamber) The system is designed to expose samples to XeF 2 gas in a cyclic (pulsed) mode in which the etch chamber is repeatedly filled with XeF 2 gas and pumped out again. Using computer controlled valves, XeF 2 from the source chamber gets expanded in the expansion chamber and then brought to the etch chamber to begin ... WebNov 29, 2016 · The wet etch process can be described by three basic steps (1) diffusion of the liquid etchant to the structure that is to be removed and (2) the reaction between the liquid etchant and the material being etched away. A reduction-oxidation (redox) reaction usually occurs. This reaction entails the oxidation of the material then dissolving the ...

WebXeF 2 vapor-phase etching is a powerful etching technique for microelectronics fabrication. The chemical reaction of silicon etching process using XeF 2 vapor is as follows.. 2XeF 2 + Si → 2Xe (g) + SiF 4 (g). Silicon surface reacts with XeF 2, and forms byproduct molecule of SiF 4. This non-plasma etching process shows unlimited etch selectivity of silicon … WebRelatively high etch rate – typically between 2 and 2.5 mils/min. Less undercut or sideways etch.
