  • Publication number: 20040214382
    Abstract: The MOS transistor of the present invention is manufactured by a conventional complementary MOS transistor technology. In the manufacturing method of the MOS transistor having nanometer dimensions, a gate having dimensions at a nanometer scale can be formed through control of the width of spacers instead of with a specific lithography technology. The doped spacers are used for forming source/drain extension regions having an ultra-shallow junction, thereby avoiding damage on the substrate caused by ion implantation. In addition, a dopant is diffused from the doped space into a semiconductor substrate through annealing to form the source/drain extension regions having an ultra-shallow junction.
