Abstract
A power semiconductor component is specified which provides for a significant reduction in the thickness of the semiconductor substrate (1) whilst at the same time optimizing the switching losses. A transparent emitter (6) and a stop layer (7) are arranged to provide a thin semiconductor and optimized switching losses. The means can be used both in semiconductor switches such as IGBT, MCT or GTO and in diodes.
