MEMS Foundry
We possess MEMS foundry equipment ranging from photo lithography aligner to packaging equipment. This gives us the capability to obtain high level quality control. Especially we own DRIE equipment for Si dry etch processing, which is used in the development of high-end MEMS gyroscope, accelerometer, and pressure sensors. We specialize particularly on deposition and drying etching of Oxide mask (TEOS; SiO2) that is used in high aspect ratio silicon etch manufacturing. We provide high quality foundry services based on over ten years of experience with self-developed manufacturing techniques.
