Abstract:
A semiconductor device includes a first silicon layer disposed between second and third silicon layers and separated therefrom by respective first and second oxide layers. A cavity within the first silicon layer is bounded by interior surfaces of the second and third silicon layers, and a passageway extends through the second silicon layer to enable material removal from within the semiconductor device to form the cavity. A metal feature is disposed within the passageway to hermetically seal the cavity.

Claim (Index 17):
A method of fabricating a semiconductor device, the method comprising:\n forming a material stack having (i) a first silicon layer disposed between second and third silicon layers and separated therefrom by respective first and second oxide layers and (ii) an oxide-filled trench extending through the first silicon layer from the first oxide layer to the second oxide layer; forming a vent that extends through at least the second silicon layer to the first oxide layer and that includes first and second interconnected passageways in which the second passageway is substantially narrower than the first passageway; removing oxide from the oxide-filled trench and regions of the first and second oxide layers through the first and second passageways of the vent to form a cavity between the second and third silicon layers; and disposing a sealant material within the second passageway to hermetically seal the cavity.
