An hermetic, gas filled or vacuum package device and method of making a
vacuum package device. The device includes a device layer having one or
more Micro Electro-Mechanical Systems (MEMS) devices. The device layer
includes one or more electrical leads coupled to the one or more MEMS
devices. The device also includes a first wafer having one or more
silicon pins, wherein a first surface of the first wafer is bonded to a
first surface of the device layer in such a manner that the one or more
silicon pins are in electrical communication with the electrical leads. A
second wafer, which may also have one or more silicon pins, is bonded to
a second surface of the device layer. The first and second wafers are
formed of borosilicate glass and the device layer is formed of silicon.
