  • Publication number: 20100327363
    Abstract: Sidewalls are formed on side surfaces of fin-shaped active regions, and then substrate regions surrounded by a device isolation groove are formed, where the widths of each substrate region in a channel length direction and in a channel width direction are respectively larger than those of the active region. Next, the sidewalls are removed, the device isolation groove and regions between the active regions are filled with an insulator film, and the insulator film is etched such that upper surfaces of the substrate regions are exposed. Next, an impurity is implanted in an upper portion of the substrate regions to form a punch through stopper diffusion layer, thereby forming fin transistors.
