Abstract
A semiconductor device includes at least one first contact region of a vertical device between a semiconductor substrate and an electrically conductive structure arranged adjacent to the semiconductor substrate, and at least one second contact region of the vertical device between the semiconductor substrate of the semiconductor device and the electrically conductive structure. The at least one first contact region is arranged adjacent to the at least one second contact region. The electrically conductive structure includes a first electrically conductive material in contact with the semiconductor substrate in an area of the at least one first contact region and a second electrically conductive material in contact with the semiconductor substrate in an area of the at least one second contact region, so that a first contact characteristic within the at least one first contact region differs from a second contact characteristic within the at least one second contact region.
