Halbleitervorrichtung mit Lötstellen und Verfahren zur Herstellung

摘要

A semiconductor device with solder bumps having a resin substrate of which both the upper and lower sides are laminated by a copper foil (3), which is provided with connection electrodes (6) for IC chips on the upper side and pad electrodes (7) for external connection on the lower side, joined with each other via through-holes (2), said pad electrodes (7) are provided with solder bumps (12), characterized by comprising forming a gold plated layer (18) on said connection electrode (6) and forming a plated layer (15) of a metal having affinity with solder, such as copper or nickel, on said pad electrodes (7).
