Abstract:
Device structures for a bipolar junction transistor and methods for fabricating a device structure using a substrate. One or more primary trench isolation regions are formed that surround an active device region of the substrate and a collector contact region of the substrate. A base layer is formed on the active device region and the collector contact region, and the active device region includes a collector. Each primary trench isolation region extends vertically to a first depth into the substrate. A trench is formed laterally located between the base layer and the collector contact region and that extends vertically through the base layer and into the substrate to a second depth that is less than the first depth. A dielectric is formed in the trench to form a secondary trench isolation region. An emitter is formed on the base layer.

Claim (Index 3):
The device structure of  claim 2  wherein the emitter includes a first emitter finger and a second emitter finger, the first secondary trench isolation region is laterally located between the first emitter finger and the first collector contact region, and the second secondary trench isolation region is laterally located between the second emitter finger and the second collector contact region.
