Abstract

A semiconductor device includes: a carrier having a die pad and a contact; a semiconductor die having opposing first and second main sides and being attached to the die pad by a first solder joint such that the second main side faces the die pad; and a contact clip having a first contact region and a second contact region. The first contact is attached to the first main side by a second solder joint. The second contact region is attached to the contact by a third solder joint. The first contact region has a convex shape facing towards the first main side such that a distance between the first main side and the first contact region increases from a base of the convex shape towards an edge of the first contact region. The base runs along a line that is substantially perpendicular to a longitudinal axis of the contact clip.
