Bipolar power semiconductor component comprising a p-type emitter and more highly doped zones in the p-type emitter, and production method

摘要

Bipolar power semiconductor component comprising a p-type emitter and more highly doped zones in the p-type emitter, and production method. The invention relates to a bipolar power semiconductor component comprising a semiconductor body (1), in which a p-doped emitter (8), an n-doped base (7), a p-doped base (6) and an n-doped main emitter (5) are arranged successively in a vertical direction (v). The p-doped emitter (8) has a number of heavily p-doped zones (82) having a locally increased p-type doping.
