Plasma abatement reduces PFC emission

Abstract

Recent studies show that plasma abatement is a practical alternative to thermal abatement devices for reducing fluorocarbon (FC) emissions from dielectric etch processes, with significantly lower CoO. Point-of-use (POU) plasma abatement devices attain high FC destruction and removal efficiency (DRE) with no process impacts and produce simple, low-molecular-weight, water-scrubble by-products.
