Classification: CPC B | IPC B

Claim 0:
1. A method, comprising:
bonding a microelectromechanical system (MEMS) wafer to a second wafer the MEMS wafer and the second wafer having a first cavity and a second cavity therebetween and
providing:
a getter layer in the first cavity over a passivation layer on the second wafer, wherein the providing the getter layer further comprises:
depositing a conductive layer over the getter layer;
patterning the conductive layer and the getter layer; and
etching the conductive layer and, by the etching the conductive layer:
exposing a first surface of the getter layer; and
exposing a second surface of the getter layer, wherein the first surface and the second surface are adjacent sides of the getter layer.
