Abstract: PURPOSE:To obtain a uniform mount, in the case an Au film is formed on one surface of the semiconductor substrate on the other surface of which functional circuits are provided, by placing an intermediate metal such as Ti, Ni, Al, and the like having an intimate contactness with respect to the film and the substrate in- between. CONSTITUTION:The mounting Au layer 3 whose thickness is 2,000Angstrom or more is deposited on the back surface of the semiconductor substrate 1 on the other surface of which an MOS FET element Q is formed. An intermediate metal layer 2 with the thickness of 500-2,000Angstrom  such as Ti, Ni, Al, and the like is placed in-between. In this constitution, the melting speed is accelerated by the decrease in the eutectic temperature of the layers 3 and 2, the intimate contactness of the substrate 1 and the layer 3 is improved, and the mounting property is enhanced. Since the melting speed is accelerated, the damages are not generated in the substrate 1, and the yield rate is improved.

Abstract: PROBLEM TO BE SOLVED: To suppress the formation of a depletion layer in the gate electrode of an NMOS transistor, to shorten the manufacturing process of a semiconductor device, and then, to reduce the manufacturing cost of the device, by making the thickness of the N<+> polycrystalline silicon of the NMOS transistor thinner than that of the P<+> polycrystalline silicon of a PMOS transistor.

The thickness d1 of the film 10 is set to a value smaller than the thickness d2 of the film 12. Since the gate electrode 10 of the NMOS transistor is different from the gate electrode 12 of the PMOS transistor, a source-drain area having a desired shape and an excellent gate electrode can be obtained simultaneously, even when the source-drain area and gate electrode are formed through a single ion implantation. Therefore, no other additional process than a thickness changing process for the gate electrode is required.
