Abstract

A method for manufacturing a semiconductor device may include the following steps: preparing a substrate; providing a gate material layer that overlaps the substrate; providing a blocking layer that partially covers the gate material layer; removing a portion of the gate material layer that is not covered by the blocking layer for forming a gate electrode; providing a blocking material layer that covers both the blocking layer and the substrate; removing a portion of the blocking material layer for forming a blocking member that has an opening, wherein the opening partially exposes the blocking layer and partially exposes the substrate; and performing ion implantation through the opening to form a doped well region in the substrate.
