Abstract:
A method of manufacturing a wafer package comprising:providing a first wafer, a second wafer, and a micro device;forming a bonding pad and a peripheral pad on said first wafer, said peripheral pad encompassing said bonding pad;forming on said second wafer a first seal substantially matching the perimeter of said bonding pad and a second seal encompassing said first seal and matching said peripheral pad;forming a well in said second wafer;bonding said first and said second wafers together using said first and said second seals and said bonding and peripheral pads to form a hermetically sealed volume therebetween, said second wafer positionable with said well over said bonding pad, and said micro device in said hermetically sealed volume between said seals; andremoving a portion of said second wafer whereby said well becomes a through hole in said second wafer, said through hole open to said bonding pad on said first wafer.
