Abstract:
A transistor includes a substrate including a trench, an insulation layer filled in a portion of the trench, the insulation layer having a greater thickness over an edge portion of a bottom surface of the trench than over a middle portion of the bottom surface of the trench, a gate insulation layer formed over inner sidewalls of the trench, the gate insulation layer having a thickness smaller than the insulation layer, and a gate electrode filled in the trench.
