Abstract:
A semiconductor device includes a semiconductor body, a stress relieving layer or layer stack disposed over at least part of the semiconductor body, the stress relieving layer or layer stack comprising a plurality of openings which yield a patterned surface topography for the stress relieving layer or layer stack, and a metal layer or layer stack formed on the stress relieving layer or layer stack and occupying the plurality of openings in the stress relieving layer or layer stack. The patterned surface topography of the stress relieving layer or layer stack is transferred to a surface of the metal layer or layer stack facing away from the semiconductor body. The stress relieving layer or layer stack has a smaller elastic modulus than the metal layer or layer stack over a temperature range.

Claim (Index 1):
A semiconductor device, comprising:\n a semiconductor body; a stress relieving layer or layer stack disposed over at least part of the semiconductor body, the stress relieving layer or layer stack comprising a plurality of openings which yield a patterned surface topography for the stress relieving layer or layer stack; and a metal layer or layer stack formed on the stress relieving layer or layer stack and occupying the plurality of openings in the stress relieving layer or layer stack, wherein the patterned surface topography of the stress relieving layer or layer stack is transferred to a surface of the metal layer or layer stack facing away from the semiconductor body, wherein the stress relieving layer or layer stack has a smaller elastic modulus than the metal layer or layer stack over at least part of an operating temperature range of the semiconductor device, wherein the metal layer or layer stack is an uppermost metal layer of the semiconductor device and comprises a contact pad, wherein the plurality of openings in the stress relieving layer or layer stack are disposed under a region of the metal layer or layer stack devoid of contact pads, wherein part of the stress relieving layer or layer stack has a generally planar surface topography, wherein the contact pad in the metal layer or layer stack is disposed over the part of the stress relieving layer or layer stack having the generally planar surface topography, so that the contact pad has a relatively top planar surface.
