Abstract
A base plate and power semiconductor module are provided, involving a basic body formed in one piece and having a front and rear side. The front side has a mounting area of the base plate. Along at least one of its edges, the basic body has at least one elevated integral part forming at least one sidewall projecting beyond the mounting area by a vertical height. At mounting area regions, the basic body has vertical thickness extending between the front and rear side and being larger than the vertical height of the sidewall. Along all edges, the basic body involves either at least one sidewall or at least one groove, but not both, at the same edge. Along at least one of its edges, the basic body involves one elevated integral part forming the at least one sidewall.
