Patent ID: 7169647

Claim:
A method for producing a conductive connection between a semiconductor chip and an external conductor structure, the method comprising: forming an elevation element on a semiconductor wafer at a surface of the semiconductor chip; depositing a nucleation layer on the elevation element and a remaining surface of the semiconductor wafer at least in a region where the conductive connection is to be produced; forming a first mask to expose a portion of the nucleation layer where the conductive connection is to be produced; forming a conductive layer over exposed portions of the nucleation layer; forming a first passivation layer over the conductive layer; forming an upper layer over the first passivation layer, the upper layer comprising a material of a soldering island; covering the soldering island of the upper layer with a second resist mask; removing portions of the upper layer that are not covered; and forming a second passivation layer such that sides of the conductive layer are covered with the second passivation layer at least in a region adjacent the soldering island.
