摘要: A bipolar transistor has a collector having a base layer provided thereon and a shallow trench isolation structure formed therein. A base poly layer is provided on the shallow trench isolation structure. The shallow trench isolation structure defines a step such that a surface of the collector projects from the shallow trench isolation structure adjacent the collector.
