Abstract

A microelectromechanical systems (MEMS) package may include a wafer having a MEMS device; a metal cap partially anchored to the wafer where at least one point between the cap and the wafer is unanchored, the metal cap at least substantially extending over the MEMS device; an electrical contact pad electrically coupled to the MEMS device; and a sealing layer disposed over the metal cap and the wafer, such that the sealing layer seals a gap between an unanchored portion of the metal cap and the wafer to encapsulate the MEMS device; wherein the electrical contact pad and the metal cap include the same composition.
