Patent ID: 8289723

Claim:
A method of fabricating a packaged-device comprising: forming grooves in a plurality of first-packaging-member forming regions included in a first packaging wafer so as to form a plurality of wiring regions defined by the grooves; forming insulating portions in the grooves; joining a surface of the first packaging wafer on which the wiring regions are formed, to a first surface of a device wafer including a plurality of device forming regions after forming the insulating portions in the grooves; forming through holes in the wiring regions of the first packaging wafer after joining the first packaging wafer to the device wafer, the through holes extending through the first packaging wafer; filling the through holes with a conductive material; joining a second packaging wafer to a second surface of the device wafer opposite the first surface, the second packaging wafer including a plurality of second-packaging-member forming regions; exposing the wiring regions by thinning the first packaging wafer after joining the first packaging wafer to the device wafer; and forming a plurality of laminated structure bodies including the first-packaging-member forming regions, the device forming regions, and the second-packaging-member forming regions by cutting the device wafer, the first packaging wafer, and the second packaging wafer after thinning the first packaging wafer.
