CtrLayer RIE 1



Equipment Description

Formerly the Advanced Vacuum Vision 320 RIE, the Georgia Tech CtrLayer RIE 1 showcases a revamped software set programmed by the IEN. It is a manually loaded Reactive Ion Etcher plasma system. It is used to etch dielectric materials and shallow silicon by using SF6 as an etching gas. The Georgia Tech CtrLayer RIE 1 has a permanent graphite plate in order to reduce temperature build up during a long process run. Small pieces up to 10" substrates are allowed in this system.
