Abstract:
1. A method of manufacturing a semiconductor device, comprising the steps of: forming at least two openings on an insulator, each of the at least two openings being in first regions; forming first semiconductor layers embedded in the at least two openings; forming an island-shaped second semiconductor layer on the first semiconductor layers, and on the insulator at a second region which is between the first regions; forming a gate insulating film over the island-shaped second semiconductor layer; forming a gate electrode over the gate insulating film; forming a first impurity region in the island-shaped second semiconductor layer, using the gate electrode as a mask; forming an interlayer insulating film over the gate electrode; and etching the interlayer insulating film selectively to form contact holes reaching the island-shaped second semiconductor layer in the first regions.
