Electrical device comprising two substrates bonded together and method of making same

摘要

An electrical device (100, 502, 602, 702) includes a plurality of integrated circuits (106) respectively fabricated in a first substrate (102) bonded to a second substrate (104) by a bond (111) that deforms above, but not below, a deformation condition. The deformation condition can be a predetermined pressure from opposing surfaces on the first and second substrates (102, 104) or is can be a predetermined combination of temperature and pressure from opposing surfaces on the first and second substrates (102, 104).
