Claim:
1. A method for forming a semiconductor device comprising: providing in a semiconductor substrate, a peripheral region including a first region, a second region, and a third region, the first region, the second region, and the third region being arranged side by side, wherein a plurality of active regions are defined by device isolation films in the first region, the second region, and the third region; forming first active regions each having a fin shape in the first region and the second region, by forming recesses at both sides of each of the plurality of active regions disposed in the device isolation films in the first region and the second region, and exposing top portions of the plurality of active regions in the first region and the second region; forming a buried metal layer in one or more of the recesses; forming a first conductive layer over one or more of the first active regions in the first region; and forming a second conductive layer over one or more of the first active regions in the second region.
