Claim 13:
14. The method according to claim 13, wherein
upon performing the first doping process on the active layer by taking the gate electrode with the opening as the first mask, a third lightly doped region and a fourth lightly doped region are further formed, wherein the third lightly doped region and the fourth lightly doped region are respectively at two sides of the gate electrode in the direction and adjacent to the gate electrode;
the second mask is also located at the third lightly doped region and the fourth lightly doped region, and upon forming the first heavily doped region, a second heavily doped region is formed at one side of the third lightly doped region away from the gate electrode, and a third heavily doped region is formed at one side of the fourth lightly doped region away from the gate electrode.
