FLIP-CHIP TYPE SEMICONDUCTOR DEVICE, PROCESS FOR FABRICATING SUCH SEMICONDUCTOR DEVICE AND PROCESS FOR MOUNTING SUCH SEMICONDUCTOR DEVICE

摘要

A flip-chip type semiconductor device includes a semiconductor chip having electrode pads formed and arranged on a chip surface thereof. Sprout-shaped metal bumps are bonded to the electrode pads on the chip, and an adhesive resin layer is formed on the chip surface of the chip such that tip ends of the sprout-shaped metal bumps are protruded from the adhesive resin layer. A circumference of the tip end of each sprout-shaped metal bump is surrounded by a protective resin material integrally swelled from the adhesive rein layer such that a tip end face of each sprout-shaped metal bump is at least exposed to the outside.
