Abstract:
An encapsulated MEMS process including a high-temperature anti-stiction coating that is stable under processing steps at temperatures over 450 C. is described. The coating is applied after device release but before sealing vents in the encapsulation layer. Alternatively, an anti-stiction coating may be applied to released devices directly before encapsulation.
