Abstract
A microelectromechanical system (MEMS) device may include a MEMS structure over a first substrate. The MEMS structure comprises a movable element. Depositing a first conductive material over the first substrate and etching trenches in a second substrate. Filling the trenches with a second conductive material and depositing a third conductive material over the second conductive material and the second substrate. Bonding the first substrate and the second substrate and thinning a backside of the second substrate which exposes the second conductive material in the trenches.
