Claim Text:
1. A semiconductor device, comprising: a first element region, a second element region, and a first isolation region including a first insulating film isolating between the first element region and the second element region; a third element region, a fourth element region, and a second isolation region including a second insulating film isolating between the third element region and the fourth element region; and a fifth element region between the second element region and the fourth element region, and a third isolation region including a third insulating film isolating between the fifth element region and the fourth element region, wherein: the first element region and the second element region have a first semiconductor film with a first film thickness disposed over a fourth insulating film; the third element region, the fourth element region, and the fifth element region have a second semiconductor film with a second film thickness thicker than the first film thickness disposed over the fourth insulating film; and the third insulating film is thicker than the first insulating film and thinner than the second insulating film.
