Abstract
The present disclosure provides a semiconductor device. The semiconductor device comprises a substrate, a plurality of isolation regions in the substrate and an active region surrounded by the isolation regions. A p-type doped region is interposed between two n-type doped regions in the substrate. A buried gate structure is formed in the substrate and disposed between the p-type doped region and the n-type doped region. The buried gate structure comprises a gate conductive material, a gate insulating layer disposed over the gate conductive material and a gate liner surrounding the gate conductive material and the gate insulating layer. A plurality of contact plugs are formed on the p-type doped region and the plurality of n-type doped regions.
