    摘要: An isolation which is higher in a stepwise manner than an active area of a silicon substrate is formed. On the active area, an FET including a gate oxide film, a gate electrode, a gate protection film, sidewalls and the like is formed. An insulating film is deposited on the entire top surface of the substrate, and a resist film for exposing an area stretching over the active area, a part of the isolation and the gate protection film is formed on the insulating film. There is no need to provide an alignment margin for avoiding interference with the isolation and the like to a region where a connection hole is formed. Since the isolation is higher in a stepwise manner than the active area, the isolation is prevented from being removed by over-etch in the formation of a connection hole to come in contact with a portion where an impurity concentration is low in the active area. In this manner, the integration of a semiconductor device can be improved and an area occupied by the semiconductor device can be decreased without causing degradation of junction voltage resistance and increase of a junction leakage current in the semiconductor device.

    摘要: A MOS transistor includes a gate oxide film, and a gate electrode which is formed by a lamination of first and second conductor films. A capacitive element includes a lower capacitive electrode formed of the first conductor film, a capacitive film made of an insulating film which is different from the gate oxide film, an upper capacitive electrode formed of the second conductor film on the capacitive film, and a leading electrode of the lower capacitive electrode formed of the second conductor film. At the same number of steps as in the case where the gate oxide film is used as the capacitive film, a semiconductor device can be manufactured with the capacitive film provided, the capacitive film being made of a nitride film or the like that is different from the gate oxide film. Consequently, a capacitive film having a great capacitance value per unit area is used so that the occupied area can be reduced and an increase in manufacturing cost can be controlled. In the semiconductor device in which a transistor, a capacitive element, a resistive film and the like are provided, the occupied area can be reduced and the manufacturing cost can be cut down.
