Micrel 6” MEMS Foundry Services







Micrel is expanding its toolset capabilities to address its fast growing MEMS business. Micrel has a state-of-the-art SPTS PegasusTM DRIE machine which boasts the fastest deep silicon etch rates available as well as superior sidewall smoothness and cross-wafer uniformity. The PegasusTM is the tool of choice for the very high aspect ratio features and large cavities required for today’s MEMS products. MEMS customers also have the option for monolithic integration with CMOS as well as access to all of Micrel's IC products for package-level integration. At Micrel, fabless customers enjoy the rare capability for production of a full MEMS sensor system at one facility. Be sure to read our whitepaper about MEMS Foundry Selection.
