Overview
The Plasma-Therm Versaline DSE (Deep Silicon Etcher) is a deep silicon etcher Plasma RIE that runs the Bosch Si process. It is primarily used for deep etching of MEMS structures in silicon. The Bosch process is used for the creation of deep, almost vertical, high aspect ratio structures and is an alternative to cryogenic chuck adapted ICP RIE systems and allows for deeper SI etches and a higher aspect ratio relative to these systems.
