This is a ICP (Inductive Charged Plasma) Deep Reactive Ion etcher from Surface Technology Systems. The platform is single-chamber, manual loadlock system. The etch process is based on the patented Laermer and Schlip process, commonly referred to as the Bosch Process. The etch process alternates between the passivating C4F8 plasma and the silicon etching SF6 plasma.
