Abstract
According to an embodiment of a power semiconductor device, the device includes: a semiconductor substrate including an IGBT region having an IGBT and a diode region having a diode. The IGBT region includes a plurality of first trenches extending perpendicular to a first main surface of the semiconductor substrate. The diode region includes a plurality of second trenches extending perpendicular to the first main surface of the semiconductor substrate. An average lateral spacing between adjacent ones of the second trenches is greater than an average lateral spacing between adjacent ones of the first trenches. Additional power semiconductor device embodiments are described herein, as are corresponding methods of production.
