Patent ID: 8043880

Claim:
A method of covering a microelectronic device, comprising: placing a membrane over a microelectromechanical system (MEMS) device, said membrane including at least one etch release hole extending therethrough; depositing photoresist over a bond pad corresponding to said MEMS device such that a top of surface of said photoresist deposited over said bond pad is at a different height than a top surface of said membrane placed over said MEMS device; depositing a layer of glass on said membrane and on said photoresist over said bond pad by physical vapor deposition using a glass target thereby forming a first glass lid covering said membrane and a second glass lid covering said photoresist over said bond pad, said first glass lid extending across said membrane and covering said at least one etch release hole, said first glass lid and said second glass lid being physically separate from each other; and selectively removing at least a portion of said second glass lid and said photoresist over said bond pad to expose said bond pad.
