Abstract:
A semiconductor device with a laminated passivation film, comprising:a semiconductor substrate having a semiconductor device at a portion of a surface thereof, the semiconductor device having an electrode on the semiconductor substrate,; and a laminated passivation film on a surface of the semiconductor substrate covering the semiconductor device, the laminated passivation film including an innermost insulation layer of SiON which covers the entire of the semiconductor device and is in contact with the surface of the semiconductor substrate and an outermost insulation layer of Si3N4 which covers the innermost insulation layer entirely such that no portion of the innermost insulation layer is exposed and said outermost layer in contact with the surface of the semiconductor substrate wherein the laminated passivation film has an opening which exposes a portion of the electrode and the outermost insulation layer is in contact with the electrode at a periphery of the opening.
