Abstract

See full text

Bipolar junction transistor (BJT) structures are provided. A BJT structure includes a semiconductor substrate, a collector region formed in the semiconductor substrate, a base region formed over the collector region, an emitter region formed over the collector region, a ring-shaped shallow trench isolation (STI) region formed in the collector region, and a base dielectric layer formed over the collector region and on opposite sides of the base region. The base dielectric layer is surrounded by an inner side wall of the ring-shaped STI region.
