Patent ID: 7491581

Claim:
A method for fabricating at least one first MEMS sensor and at least one second MEMS sensor, the method comprising: fabricating a first wafer including at least one first MEMS sensor first subassembly and at least one second MEMS sensor first subassembly; fabricating a second wafer including at least one first MEMS sensor second subassembly corresponding with each at least one first MEMS sensor first subassembly and at least one second MEMS sensor second subassembly corresponding with each at least one second MEMS sensor first subassembly; bringing the second wafer in to contact with the first wafer to align the at least one first MEMS sensor second subassembly with the at least one first MEMS sensor first subassembly forming at least one first MEMS sensor and to align the at least one second MEMS sensor second subassembly with the at least one second MEMS sensor first subassembly forming at least one second MEMS sensor; and fusing the second wafer to the first wafer encompassing each at least one first MEMS sensor with a first joint having an first joint interior aspect oriented toward the at least one first MEMS sensor and a first joint exterior aspect oriented away from the MEMS sensor and with a second joint encompassing each at least one second MEMS sensor having a second joint interior aspect orient toward the at least one second MEMS sensor and a second joint exterior aspect oriented away from the MEMS sensor.
