Chemical dry etching 原理

WebThe plasma etching (PE) is an absolute chemical etch process (chemical dry etching, CDE). The advantage is that the wafer surface is not damaged by accelerated ions. Due to the movable particles of the etch gases the etch profile is isotropic, thus this method is used to remove entire film layers (e.g. back side clean after thermal oxidation). Web1.08.3.2 Cryogenic Dry Etching. Cryogenic dry etching is a variation of the passivation technique based on sidewall oxidation. For cryogenic temperatures typically around 175 …
