Abstract: In an LCD driver IC, a high-breakdown-voltage MISFET is mounted together with a typical low-breakdown-voltage MISFET. Because the high-breakdown-voltage MISFET has a gate oxide film thicker than that of the typical MISFET, the electrode of the high-breakdown-voltage MISFET is inevitably high in level. Accordingly, the depth of a gate contact is shallow so that process compatibility with the typical portion is necessary. In the present invention, in, e.g., the channel width direction of the high-breakdown-voltage MISFET, the boundary of a thick-film gate oxide region is located inwardly of the end of a gate electrode. At the gate electrode portion thus lowered in level, a gate contact is disposed so that the boundary of the thick film is located inwardly of the end of the gate electrode and between the gate contact and a channel end.
