A method for forming a semiconductor device is disclosed. An anti-fuse is formed at a buried bit line such that the area occupied by the anti-fuse is smaller than that of a conventional planar-gate-type anti-fuse, and a breakdown efficiency of an insulation film is increased. This results in an increase in reliability and stability of the semiconductor device. A semiconductor device includes a line pattern formed over a semiconductor substrate, a device isolation film formed at a center part of the line pattern, a contact part formed at both sides of the line pattern, configured to include an oxide film formed over the line pattern, and a bit line formed at a bottom part between the line patterns, and connected to the contact part. |
