Selectivity

Abstract

Plasma is seldom used to etch blanket films in microelectronics fabrication. The etching of photoresist and the underlying substrate is also important since the etching selectivity is never infinite and aspect ratio dependent etching often causes some etching of the underlying substrate or thin film.
