Abstract: A performance and reliability of a semiconductor device are improved. On a semiconductor substrate, a gate electrode for a first MISFET and a dummy gate electrode for a second MISFET are formed, and then, an insulating film is partially formed on the gate electrode. Then, on the semiconductor substrate, an insulating film is formed so as to cover the dummy gate electrode, the gate electrode and other insulating film. Then, the dummy gate electrode is exposed by polishing the insulating film. In this polishing, the insulating film is polished under a condition that a polishing speed of the other insulating film is smaller than a polishing speed of the insulating film. Then, after the dummy gate electrode is removed, the gate electrode for the second MISFET is formed in a region where the dummy gate electrode has been removed.

In a SRAM cell formed in a SOI board, the electrical coupling between the drain region of a driver transistor (which is also a source/drain region of an access transistor), and the drain region of a load transistor, and the electrical coupling between the drain region of another driver transistor (which is also a source/drain region of another access transistor) and the drain region of another load transistor are established by wiring structures formed by using a SOI layer under an isolation oxide film which is partial trench isolation, respectively.

An oxide film (13) is formed by oxidizing an edge section and a lower major surface of an SOI substrate (10). This oxidizing step is performed in a manner similar to LOCOS (Local Oxide of Silicon) oxidation by using an oxide film (11) exposed on the edge section and lower major surface of the SOI substrate (10) as an underlying oxide film. Then, the thickness of the oxide film (13) is greater than that of the oxide film (11) on the edge section and lower major surface of the SOI substrate (10). The semiconductor substrate prevents particles of dust from being produced at the edge thereof.
