Abstract:
1. A method for fabricating a semiconductor device, comprising: forming a fin protruded from a substrate and extended in a first direction and; forming a gate line on the fin and the substrate, wherein the gate line is extended in a second direction crossing the first direction; conformally forming an amorphous material layer to cover the substrate, the fin, and the gate line; removing a part of the amorphous material layer to form a first remaining amorphous layer on side walls of the fin and a second remaining amorphous layer on side walls of the gate line; annealing the first remaining amorphous layer and the second remaining amorphous layer to crystallize the first remaining amorphous material layer and the second remaining amorphous material layer into a monocrystalline material layer and a polycrystalline material layer, respectively; and removing the polycrystalline material layer.
