Abstract
Process for producing electrical-connections on a semiconductor package containing an integrated-circuit chip and with an external protective layer having apertures that least partly expose metal electrical-connection regions, and semiconductor package provided with such metal electrical-connections. The apertures having walls are filled with a metal electrical-connection layer covering at least their walls. A metal solder drop is soldered to the connection layer so that it is not in contact with the external protective layer.
