Abstract:
A method for making and a semiconductor device comprises a silicon die including a metal contact region and, at least one passivation layer covering the semiconductor die and patterned such as to form an opening to the metal contact region of the semiconductor die. A continuous part of a contact layer comprises a refractory metal, and overlaps and completely covers the opening in the at least one passivation layer to contact the metal contact region in the opening and adhere to the at least one passivation layer along the entire edge of the continuous part. The contact layer comprises at least an adhesion layer and at least a diffusion barrier layer. A noble metal layer is arranged over the contact layer and completely covers the continuous part to adhere to the at least one passivation layer around the edge of the continuous part.

Claim (Index 8):
The method of  claim 7 , wherein said lift-off mask has a footprint at a base thereof, where it adheres to the at least one passivation layer, that is larger than a footprint of the continuous part of the contact layer.
