  • Patent number: 9029255
    Abstract: A method for fabricating a semiconductor device is provided. A first polysilicon layer of a first conductivity type is provided on a substrate having first and second active regions. An ion implantation process is performed in the polysilicon layer corresponding to the second active region by using a dopant of a second conductivity type opposite to the first conductivity type, and silane plasma is introduced during the ion implantation process to form a second polysilicon layer thereon and convert the first conductivity type of the first polysilicon layer corresponding to the second active region to the second conductivity type. The first and second polysilicon layers are patterned to form a first gate layer corresponding to the first active region and a second gate layer corresponding to the second active region. A semiconductor device is also provided.
