Abstract:
1. A method for forming a microelectromechanical system (MEMS) device comprising: forming a MEMS structure over a first substrate, wherein the MEMS structure comprises a movable element; forming a bonding structure over the first substrate; forming a support structure over the first substrate; bonding the MEMS structure to a second substrate; and forming a through substrate via (TSV) from a backside of the second substrate, wherein the overlying TSV is aligned with the bonding structure and the support structure, wherein, in a plane parallel to a major surface of the second substrate, the bonding structure has a linear perimeter and the support structure has non-linear perimeter protruding from the linear perimeter of the bonding structure, the non-linear perimeter of the support structure being spaced from an outer perimeter of a projection of the overlying TSV by a constant width.
