Abstract

A semiconductor device includes a chip carrier and a semiconductor die with a semiconductor portion and a conductive structure. A soldered layer mechanically and electrically connects the chip carrier and the conductive structure at a soldering side of the semiconductor die. At the soldering side an outermost surface portion along an edge of the semiconductor die has a greater distance to the chip carrier than a central surface portion. The conductive structure covers the central surface portion and at least a section of an intermediate surface portion tilted to the central surface portion. Solder material is effectively prevented from coating such semiconductor surfaces that are prone to damages and solder-induced contamination is significantly reduced.
