  • Patent number: 11217529
    Abstract: A semiconductor device and method is disclosed. The semiconductor device may include a semiconductor substrate including an active area, a metal layer structure over the active area, wherein the metal layer structure is configured to form an electrical contact, the metal layer structure including a solder area, a buffer area, and a barrier area between the solder area and the buffer area, wherein, in the barrier area, the metal layer structure is further away from the active area than in the solder area and in the buffer area, and wherein each of the solder area and the buffer area is in direct contact with the active area or with a wiring layer structure arranged between the active area and the metal layer structure.

  • Patent number: 10896887
    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 different elastic modulus than the metal layer or layer stack over a temperature range.
