Abstract:
A semiconductor arrangement includes a lower semiconductor chip, an upper semiconductor chip arranged over an upper main side of the lower semiconductor chip, a metallization layer arranged on the upper main side of the lower semiconductor chip, and a bonding material which fastens the upper semiconductor chip on the lower semiconductor chip. The metallization layer includes a structure with increased roughness in comparison with the rest of the metallization layer, the structure being arranged along a contour of the upper semiconductor chip.
