Abstract:
1. A semiconductor device comprising: a gate electrode formed on semiconductor substrate with an insulation film formed therebetween; a source region formed on one side of the gate electrode and having a lightly doped source region and a heavily doped source region having a higher carrier concentration than the lightly doped source region; a drain region formed on the other side of the gate electrode and having a lightly doped drain region and a heavily doped drain region having a higher carrier concentration than the lightly doped drain region; a first silicide layer formed on the source region; a second silicide layer formed on the drain region; a first conductor plug connected to the first silicide layer; and a second conductor plug connected to the second silicide layer, the heavily doped drain region being formed in a region of the lightly doped drain region except a peripheral part thereof, and the second silicide layer being formed in a region of the heavily doped drain region except a peripheral part thereof.
