Abstract:
The invention relates to a component with multi-layered connection surfaces that can be soldered or bonded to a substrate (SU). Said component has, in addition to the electrically conductive pad metallisation (PM) and the UBM-metallisation (UBM), an electrically conductive stress compensation layer (SK) that is arranged between the substrate and pad-metallisation or between the pad-metallisation and the UBM-metallisation. The stress insensitivity of the connection metallisation is obtained by a stress compensation layer, the E-module thereof being lower than that of the UBM-metallisation.
