Etched depth
WebAn etch depth is realized by controlling the ratio of the substrate (Si) to resist etching rates. In this study, the two feature (step) sizes considered for staircase structures were 0.5 lm and 1.0 lm, and the depth resolu-tion (step height) achieved was 20 nm. One of the goals in the etching process was to achieve the 1:1 ratio of the sil- WebAug 30, 2024 · This chemical etching guide highlights the key considerations design engineers must think about to get the most from the etching process.

The two fundamental types of etchants are liquid-phase ("wet") and plasma-phase ("dry"). Each of these exists in several varieties. The first etching processes used liquid-phase ("wet") etchants. This process is now largely outdated, but was used up until the late 1980s when it was superseded by dry plasma etching. The wafer can be immersed in a bath of et…
