MEMS device and assembly method
First Claim
1. A method of bonding a MEMS device to a substrate to form a MEMS device assembly, the method comprising:
- determining at least one of a thickness profile of the MEMS device and a flatness of a mating surface of the substrate;
depositing adhesive onto at least one of a mating surface of the MEMS device and the mating surface of the substrate; and
bringing the mating surfaces of the MEMS device and substrate together, such that the adhesive bonds the MEMS device to the substrate,wherein a volume of the adhesive deposited at respective locations on one or both of the mating surfaces is selected to compensate for local variations in the thickness profile of the MEMS device or the flatness of the mating surface of the substrate.

Abstract
A method of bonding a MEMS device to a substrate to form a MEMS device assembly. A thickness profile of the MEMS device and/or the flatness of the mating surface of the substrate is determined. An adhesive is deposited onto a mating surface of the MEMS device and/or the mating surface of the substrate. The mating surfaces of the MEMS device and substrate are brought together, such that the adhesive can bond the MEMS device to the substrate. The volume of adhesive deposited at particular locations on the mating surface is varied to compensate for local variations in the thickness profile of the MEMS device and/or the flatness of the mating surface of the substrate.
