    摘要: A polysilicon electrode is formed in an active area surrounded by an isolation on a silicon substrate with a gate oxide film sandwiched therebetween, a polysilicon wire is formed on the isolation, and a source/drain region is formed on both sides of the polysilicon electrode. On the both sides of a polysilicon film constituting the electrode and the wire are formed side walls having a height that is 4/5 or less of the height of the polysilicon film. Furthermore, the polysilicon film is provided with a silicide layer in contact with the top surface and portions of the side surfaces of the polysilicon film projecting from the side walls, and another silicide layer is formed in contact with the source/drain region. Since the sectional area of the silicide layer is increased, the resistance value can be suppressed even when the dimension of the polysilicon film is minimized. Thus, the invention provides a semiconductor device including an FET having a low resistance value applicable to a refined pattern.

    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: There are provided: an isolation protruding upward from a semiconductor substrate in an active region; a gate electrode formed in the active region; and a pair of dummy electrodes formed to extend over the active region and the isolation and substantially in parallel with the gate electrode. Each of the gate electrode and dummy electrodes is composed of a lower film and an upper film. The lower films of the dummy electrodes are formed flush with the isolation and in contact with the side edges of the isolation. With the dummy electrodes, any gate electrode can be formed in a line-and-space pattern, so that the finished sizes of the gate electrode become uniform. This enables a reduction in gate length and therefore provides a semiconductor device of higher integration which is operable at a higher speed and substantially free from variations in finished size resulting from the use of different gate patterns.
