Claim Text:
1. A sensor, comprising: a first substrate including a conductive layer vertically arranged between a semiconductor layer and a conductive contact structure, wherein the conductive layer includes stationary regions and a movable region extending laterally between the stationary regions, wherein the movable region includes a plurality of recesses extending downwardly into an upper side of the conductive layer, wherein some of the plurality of recesses taper inwardly to adjoin openings extending through perforated regions in a lower side of the conductive layer and other of the plurality of recesses terminate at an upper surface of a conductive membrane of the conductive layer that is laterally arranged between the perforated regions, wherein the conductive contact structure protrudes outwardly from a lower side of the conductive layer, beyond a face of the first substrate, and wherein the conductive contact structure is electrically coupled to a pressure-sensitive micro-electrical-mechanical (MEMS) structure on the first substrate; a second substrate including a receiving structure having a conductive surface which is recessed from a face of the second substrate by sidewalls that bound the conductive surface, wherein the conductive surface is electrically coupled to a complementary metal oxide semiconductor (CMOS) device on the second substrate; and a conductive bonding material to physically adhere the conductive contact structure to the conductive surface and to electrically couple the MEMS structure to the CMOS device.
