Abstract: PURPOSE:To easily control a threshold value and to restrain a breakdown voltage between a source and a drain from dropping by a method wherein a film thickness of a gate oxide film of a semiconductor element constituting a read-only memory is set to be large. CONSTITUTION:A plurality of semiconductor elements 1a, 1b provided with a source electrode 16, a drain electrode 17 and a gate electrode 19 formed via a gate oxide film 18 are arranged on an identical substrate 11; one part 1a of the semiconductor elements constitutes a read-only memory which has been written by implanting impurities 20 into the surface of the substrate 11 directly under the gate oxide film 18. A film thickness of the gate oxide film 18 of the semiconductor elements 1a, 1b constituting the readonly memory is set to be larger than a film thickness of a gate oxide film 26 of another semiconductor element 1'. As a result, the gate oxide film hardly induces electricity as compared with the gate oxide film 26 of the semiconductor element 1'; a concentration of impurities implanted into the surface of the substrate 11 directly under the gate oxide film 18 can be set to a remarkably low value. Thereby, it is possible to easily control a threshold value and to restrain breakdown voltage between the source and the drain from dropping.
