Abstract
A semiconductor device has a circuit carrier with a number of internal contact areas is disclosed, which includes a first material with a first electrochemical potential, and a semiconductor chip with an active surface and a number of chip contact areas, which include a second material with a second electrochemical potential. Bonding wire connections are arranged between the chip contact areas and the internal contact areas of the leadframe and comprise a third material with a third electrochemical potential. The connecting points between the chip contact areas and the bonding wires and/or the connecting points between the internal contact areas and the bonding wires are coated with an anticorrosive layer.
