发明名称 Semiconductor device having an expanded storage node contact and method for fabricating the same
摘要 A semiconductor device is disclosed that stably ensures an area of a storage node contact connected to a junction region in an active region of the semiconductor device and is thus able to improve the electrical properties of the semiconductor device and enhance a yield, and a method for fabricating the same. The semiconductor device includes a semiconductor substrate having an active region including a gate, a storage node contact region, and an isolation region that defines the active region. A passing gate and an isolation structure surrounding the passing gate are formed in the isolation region. A silicon epitaxial layer is selectively formed over an upper portion of the passing gate to expand the storage node contact region.
