Abstract:
1. A semiconductor device for use in a stacked configuration of the semiconductor device and a further semiconductor device, the semiconductor device comprising: a substrate comprising at least part of an electronic circuit provided at a first side thereof, the substrate comprising a passivation layer at the first side and having a substrate via that extends from the first side to a via depth beyond a depth of the electronic circuit such that it is reconfigurable into a through-substrate via by backside thinning of the substrate, and a patterned masking layer on the first side of the substrate, wherein the patterned masking layer comprises at least a trench extending over the passivation layer and extending fully through the patterned masking layer and being filled with a redistribution conductor, and wherein the substrate via and the redistribution conductor comprise metal paste and together form one piece; wherein the substrate via and the redistribution conductor form an electrical connection with no physical interface between the substrate via and the redistribution conductor.
