Patent ID: 7029981

Claim:
A method of forming a bipolar junction device in an integrated circuit comprising: forming a base region in a surface of a collector region of a substrate; forming an emitter region in the surface of the base region; forming a mask exposing the total surface of the emitter region and adjoining portions of the surface of the base region; forming a first dielectric layer over the exposed surfaces; forming a field plate layer 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; removing a portion of the field plate layer to expose a first portion of the emitter surface; forming a second dielectric layer over the field plate layer and the exposed portion of the emitter; removing a portion of the first and second dielectric layers to expose the first portion of the emitter surface and adjoining portions of the field plate layer; and forming a common contact to the exposed first portion of the emitter surface and the adjoining portions of the field plate layer.
