Abstract

A method of forming an integrated circuit device includes providing a semiconductor substrate; forming a gate structure on the semiconductor substrate; and performing a pre-amorphized implantation (PAI) by implanting a first element selected from a group consisting essentially of indium and antimony to a top portion of the semiconductor substrate adjacent to the gate structure. The method further includes, after the step of performing the PAI, implanting a second element different from the first element into the top portion of the semiconductor substrate. The second element includes a p-type element when the first element includes indium, and includes an n-type element when the first element includes antimony.
