A gate-overlap-drain structure is obtained by a single pair of a single impurity implantation process and a single laser anneal process, wherein the improved gate-overlap-drain structure includes lightly activated high impurity concentration regions exhibiting substantially the same function as the lightly doped drain regions, wherein the lightly activated high impurity concentration regions are bounded with high impurity concentration regions serving as source and drain regions. The boundaries are self-aligned to edges of a gate electrode. Side regions of the gate electrode overlap the lightly activated high impurity concentration regions.
