Abstract
A vertical semiconductor device having a vertical channel region is disclosed. The vertical semiconductor device includes a pillar having a vertical channel region, a bit line buried in a semiconductor substrate located at a lower part of the pillar, and a body connection unit configured to couple at least one sidewall of the pillar to the semiconductor substrate. As a result, the floating body effect of the vertical semiconductor device can be more effectively removed.
