Patent 7582514 was granted and assigned to Bosch (company) on September, 2009 by the United States Patent and Trademark Office.
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.
