Principle
- Plasma of reactive gases is created by microwave sources
- Enhanced ion bombardment with RF bias
Technologies
Plasma Enhanced Chemical Vapor Deposition (PECVD) is a plasma assisted reactive process to deposit thin films from a gas state (vapor) into a solid state on a substrate.
Reactive Ion Etching (RIE) uses reactive gases and ion bombardment for physically and chemically etching of the substrate surface.
