  • Abstract
    A noble gate/N- overlapped Tr. fabricated using oblique rotating ion implantation technique was developed. It is confirmed that this Tr. meets high performance M bit DRAMs´ requirements, that is, high drain current, enough punchthrough voltage and low substrate current. The mechanism of this Tr.´s action is analyzed by simulation and is concluded that peak position of electric field is located far from the drain current pass in this Tr.´s structure. The maximum electric field is also relaxed by formation of N- layer using oblique ion implantation.
