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

摘要

A bipolar power semiconductor component configured as an IGBT includes a semiconductor body, in which a p-doped emitter, an n-doped base, a p-doped base and an n-doped main emitter are arranged successively in a vertical direction. The p-doped emitter has a number of heavily p-doped zones having a locally increased p-type doping.
