Claim Text:
1. A producing method of a semiconductor device, comprising: forming a first transistor and a second transistor in a first well of a first conductive type and a second well of a second conductive type, respectively, the first well and the second well being formed in a semiconductor substrate, the first transistor and the second transistor including a gate electrode successively formed over the first well and the second well; forming a first film and a second film over the first transistor and the second transistor, respectively, a boundary region between the first film and the second film being placed out of a boundary between the first well and the second well to the first well and placed over the first well of the first well and the second well; forming a contact hole placed out of the boundary region between the first film and the second film to the second film and extending to the gate electrode through the second film of the first film and the second film; and forming a contact electrode in the contact hole.
