概要（Overview）

STS Multiplex is a type of etcher that offers a large range of materials etching possibility such as insulators (SiO2, Si3N4 and SiC), silicon, metals (Al Alloys, Pt, Ti) and some polymers. It is dedicated for etching metals (processes under chlorine chemistry), quartz (fluorine/carbonate chemistry) and polyimide (oxygen chemistry). STS offers a range of different platform options, each compatible with all STS process technologies. The Multiplex has a single process chamber with manually loaded vacuum loadlock and carousel wafer handler for 2-4 wafers.
