A method of forming bipolar junction devices, including forming a mask to
expose the total surface of the emitter region and adjoining portions of
the surface of the base region. A first dielectric layer is formed over
the exposed surfaces. A field plate layer is formed on the first
dielectric layer juxtaposed on at least the total surface of the emitter
region and adjoining portions of the surface of the base region. A
portion of the field plate layer is removed to expose a first portion of
the emitter surface. A second dielectric layer is formed over the field
plate layer and the exposed portion of the emitter. A portion of the
second dielectric layer is removed to expose the first portion of the
emitter surface and adjoining portions of the field plate layer. A common
contact is made to the exposed first portion of the emitter surface and
the adjoining portions of the field plate layer. In another embodiment,
the field plate and emitter contact are formed simultaneously.
