A refresh characteristic of a DRAM memory cell is improved and the performance of a MISFET formed in the periphery thereof and constituting a logic circuit is improved.Each gate electrode in a memory cell area is formed of p type polycrystalline silicon, and a cap insulating film on each gate electrode and a sidewall film on the sidewall thereof are formed of a silicon oxide film. A polycrystalline silicon film formed on the gate electrodes and between the gate electrodes is polished by a CMP method, and thereby contact electrodes are formed. Also, sidewall films each composed of a laminated film of the silicon oxide film and the polycrystalline silicon film are formed on the sidewall of the gate electrodes in the logic circuit area, and these films are used as a mask to form semiconductor areas. As a result, it is possible to reduce the boron penetration and form contact electrodes in a self-alignment manner. In addition, the performance of the MISFET constituting the logic circuit can be improved.

Desired operating characteristics are obtained from an MISFET in which a p-type silicon gate electrode is used by preventing the leakage of boron into the channel region in the following way. N-type amorphous silicon 9n is formed by ion-implanting phosphorus into an amorphous silicon. Next, boron is ion-implanted in n-type amorphous silicon 9n to convert it into p-type amorphous silicon 9p. Amorphous silicon 9p is then crystallized. Finally, the gate electrode of the MISFET is constructed of the p-type polycrystalline silicon, which has been obtained in the above steps, and in which phosphorus and boron have been implanted.

摘要:
Source and drain regions are formed in first regions of low concentration formed on a surface of a semiconductor surface, and a second region with doping concentration higher than that of the first regions is formed around the first regions. Further in the second region, third regions with doping concentration higher than that of the second region are formed separate from each other. By virtue of this, a rise of the threshold voltage attendant on a decrease of the channel length is canceled out by the third regions and the short channel effect is suppressed. Further, since doping concentration of the first region is low, high carrier mobility can be obtained.
