  • Patent number: 11664425
    Abstract: A method for fabricating p-type field effect transistor (FET) includes the steps of first providing a substrate, forming a pad layer on the substrate, forming a well in the substrate, performing an ion implantation process to implant germanium ions into the substrate to form a channel region, and then conducting an anneal process to divide the channel region into a top portion and a bottom portion. After removing the pad layer, a gate structure is formed on the substrate and a lightly doped drain (LDD) is formed adjacent to two sides of the gate structure.
