Plasma Etching at IEN: An Overview of Equipment and Processes - Hang Chen
From Kathryn Gentilello on February 27th, 2017
Plasma etching has become one of the most important techniques in IC fabrication. It plays a critical role in creating geometries of extremely small size for highly integrated devices. Plasma etching techniques utilize plasma created from appropriate gas mixtures and RF excitation to remove surface material physically or chemically (or both) from a substrate. Plasma etching can be categorized by the material as metal etching, silicon etching and dielectric etching, or it can be categorized by the technology as electron cyclotron resonance (ECR), reactive ion etching (RIE) or inductively coupled ion (ICP).
