Abstract
A semiconductor device and a method for manufacturing the same are disclosed, which form a bit line only at one side of a line pattern by partially etching a semiconductor substrate in a vertical gate structure, such that a body tied structure for reducing the floating body effect can be implemented. A semiconductor device includes a line pattern formed over a semiconductor substrate, a bit line buried in a bottom part of one side of the line pattern, and a gate formed over the bit line, and located perpendicular to the bit line.
