    摘要: An ion implanting process allows for shallow source and drain junctions of the transistor. According to one example embodiment, a BARC layer is formed over a gate, and a poly-crystalline or amorphous silicon shield is deposited over the source and drain regions, then the BARC and silicon are chemically mechanically polished. The poly-crystalline or amorphous silicon shield absorbs the initial impact the dopant species of ion implantation and reduces the incidence of irreversible source/drain crystal damage caused by the process. After the ion implantation, the species implanted in the poly or amorphous silicon is diffused into the source/drain regions by annealing. An additional siliciding of the poly or amorphous silicon covering the source and drain minimizes the need for deeper source/drain junctions and hence improves short-channel properties.
