Pressure sensors

MEMpax® is ideal for use in pressure sensors. Available as unpolished and structured wafer, MEMpax® acts as a pedestal that carries the functional MEMS die. These are widely used in the sectors automotive, industry and transportation and healthcare, where SCHOTT has established a long-standing and trusted presence.

MEMS mirrors

MEMpax® is widely used as a window in various MEMS mirror applications due to its unique thermal, optical, cosmetic and geometric properties. A thermal match to silicon opens up the possibility for anodic bonding to enable hermetic packages, while the availability of low thicknesses offers smaller form factors and improved optical application designs. In addition, the pristine surface can be combined with effective anti-reflective coatings.
