Abstract
A method of fabricating a semiconductor device is disclosed. An example method sequentially forms a gate insulation film and a sacrificial film on a semiconductor substrate. In addition, the example method forms a bowing hollow by selectively etching the sacrificial layer, forms gate material on the gate insulation film exposed through the bowing hollow and the sacrificial film, and forms a gate by anisotropically etching the gate material such that the gate material remains on an inner side wall of the bowing hollow.
