06 Plasma, Etch & Pattern Transfer

Definition

Plasma etch is a dry material-removal process in which a plasma supplies reactive species and/or energetic ions that remove selected wafer material through chemical and physical mechanisms.

Application

Used to transfer lithographic patterns into semiconductor, dielectric, and conductor layers and to form anisotropic, high-aspect-ratio features in logic and memory fabrication.
