Patent ID: 11905170
Assignee: INVENSENSE, INC.
Field: Micro-structural and nano-technology (Chemistry)
Classification: CPC B | IPC B

Claim 20:
21. A method comprising:
forming an eutectic bond tether that structurally connects a tab region to a semiconductor tab region, wherein the tab region structurally connects a first die to a second die, wherein the first die comprises a first Micro-Electromechanical System (MEMS) device eutecticly bonded to a first semiconductor device, and wherein the second die comprises a second MEMS device eutecticly bonded to a second semiconductor device, wherein the tab region includes a handle wafer layer disposed over a fusion bond oxide layer that is disposed on an actuator (ACT) layer, wherein the tab region is positioned above a semiconductor tab region, and wherein the eutectic bond tether maintains the tab region in place subsequent to a tab dicing process, and wherein the tab region, the first die, the second die, and the semiconductor tab region form a cavity therein;
tab dicing a first region of the tab region disposed between the first die and the second die that cuts through the handle wafer layer and the fusion bond oxide layer and the ACT layer; and
subsequent to the tab dicing the first region, removing the tab region.
