Abstract:
A method for cohesively connecting a first component of a power semiconductor module to a second component of a power semiconductor module by sintering, the method comprising the steps of: applying a layer of unsintered sinter material to a predetermined bonding surface of the first component, arranging the second component on the surface layer of unsintered sinter material, attaching the second component to the first component by applying pressure and/or temperature on a locally delimited partial area within the predetermined bonding surface, processing the first and/or second component and/or other components of the power semiconductor module, and complete-area sintering of the sinter material.
