Abstract:
A flip-chip type semiconductor device comprising:a semiconductor substrate; a pad electrode formed on the semiconductor substrate; an insulating film formed on the entire surface of the semiconductor substrate, said insulating film having an opening above the pad electrode; a wiring portion patterned on the pad electrode and the insulating film, the wiring portion having a land portion extending away from the pad electrode; a metal cost electrode formed on the land portion of the writing portion, such that a longitudinal axis of the electrode fails to pass through the pad electrode; a metal bump formed on the electrode; a support plate having holes each having a diameter larger than the diameter of the metal bump and formed at positions adjusted to the metal bumps, said support plate being arranged above the semiconductor substrate with an appropriate interval between said support plate and said semiconductor substrate such that the metal bump projects from said support plate; and an insulating resin layer formed between the semiconductor substrate and the support plate, said electrode being buried in the insulating resin layer; wherein said metal post electrode is buried in said insulating resin layer such that a joint portion between said metal bump and said metal post electrode is reinforced by said insulating resin layer.
