ANTI-GETTER: EXPANDABLE POLYMER MICROSPHERES FOR MEMS DEVICES
摘要
A method of fabricating a MEMS device includes depositing an expandable material into a first recess of a cap wafer. The cap wafer includes a plurality of walls that surround and define the first recess and a second recess. The cap wafer is bonded to a MEMS wafer including a first MEMS device and a second MEMS device. The first MEMS device is encapsulated in the first recess, and the second MEMS device is encapsulated in the second recess. The expandable material is then heated to at least an activation temperature to cause the expandable material to expand after the first recess has been sealed. The expansion of the expandable material causes a reduction in volume of the first recess.
