Abstract:
1. A semiconductor device, comprising: a silicon substrate having an active area defined by a field oxide layer formed thereon, wherein the silicon substrate has a first and a second amorphous layers in the active area and a first region between the first and the second amorphous layers in the active area, and wherein the first region acts as a channel; a first silicide layer, which completely occupies the first amorphous layer; a second silicide layer, which completely occupies the second amorphous layer; a gate electrode, which is formed over the first region of the silicon substrate; and a side wall, spacer which is formed next to the gate electrode, and which is formed on the first region and on one of the first and the second silicide layers, wherein each interface junction between one of the first and the second silicide layers, which is located directly below the side wall, spacer and the silicon substrate located in the first region, includes a (111) silicon plane.
