摘要： A semiconductor device includes a transistor. The transistor includes a substrate having an inclined surface, a first upper surface extending from a lower portion of the inclined surface, and a second upper surface extending from an upper end of the inclined surface. A gate stack structure is formed on the inclined surface and includes a gate electrode. A first impurity region formed on one of the first and second upper surfaces contacts the gate stack structure. A second impurity region formed on the second upper surface contacts the gate stack structure. A channel between the first and second impurity regions is formed along the inclined surface in a crystalline direction.
