Slanted etching
WebAug 26, 2015 · The slanted plasma etching process was conducted using a Faraday cage system, which was described in detail in a previous study. 16 The material used to create the channel structures was a Si substrate with a polycrystalline Si (poly-Si) film on the etch stop layer. A pattern of holes was delineated on the poly-Si film by optical lithography. WebAug 31, 2024 · The etch profiles of the Pd films etched under 25% and 50% CH 3 OH/Ar gas generally showed that the films had very rough sidewalls and slanted slopes of the TiN hard mask and Pd films, which are not satisfactory for real applications. The reason why Pd etching with the CH 3 OH/Ar gas produced uneven sidewalls is still unclear.
