Abstract
The present invention discloses a semiconductor device, the device comprising a semiconductor layer on a substrate. A gate oxide and a gate electrode are formed on the semiconductor substrate. A gate conductive layer is formed on the gate electrode. A first doped region is formed in the semiconductor layer. A dielectric spacer is optionally formed onto the sidewall of the gate electrode and part of the semiconductor layer. A second doped region is formed from a predetermined distance to the gate electrode, wherein the predetermined distance is no less than the distance between the first doped region and the gate electrode. A third doped region is formed adjacent to the first doped region in the semiconductor layer and between the first doped region and the second doped region.
