Bipolar transistor having an electrode structure suitable for integration

摘要

A contact hole for guiding an emitter electrode of bipolar transistors continuously arrayed and a contact hole for guiding a base electrode are positioned not to be arranged in the continuous array direction of the bipolar transistors. Also, the emitter electrode and the base electrode are respectively drawn from these contact holes in two directions different from the continuous array direction of the bipolar transistors. At least one of the base electrode and the emitter electrode is formed on a conductive layer of a polycide structure contacting an active region in a substrate to be connected.
