A wafer bonding company in Sunnyvale

MEMS Engineering and Material, Inc. is a leading provider of SOI (silicon on insulator) wafers. We specialize in fabricating SOI wafers, customized bonding structures and silicon wafers.

With decades of research and development, we have developed proprietary technology that allows us to supply SOI wafers with ultra-uniform device layers and ultra-low stress. We supply SOI wafers with the most comprehensive specifications on the market.

Our bonding work extends beyond SOI to silicon on glass, sapphire and quartz, and to III-V, GaN and PZT on silicon, made possible by a proprietary low-temperature anneal whose bond strength matches a high-temperature anneal. Alongside our own products we offer wafer foundry services, from single process steps to prototype runs.

We keep a working inventory of SOI, CZ and float zone wafers so many orders ship from stock, and we work with customers who need something no catalog lists, including partnerships to develop new bonded structures.
