    摘要: The structure and method of forming a notched gate MOSFET disclosed herein addresses such problems as device reliability. A gate dielectric (e.g. gate oxide) is formed on the surface of an active area on the semiconductor substrate, preferably defined by an isolation trench region. A layer of polysilicon is then deposited on the gate dielectric. This step is followed by depositing a layer of silicon germanium) (SiGe). The sidewalls of the polysilicon layer are then laterally etched, selective to the SiGe layer to create a notched gate conductor structure, with the SiGe layer being broader than the underlying polysilicon layer. Sidewall spacers are preferably formed on sidewalls of the SiGe layer and the polysilicon layer. A silicide layer is preferably formed as a self-aligned silicide from a polysilicon layer deposited over the SiGe layer, to reduce resistance of the gate conductor. One or more other processing steps (e.g. source and drain implants, extension implants, and pocket lightly doped drain (LDD) implants), gate conductor stack doping, and silicidation are preferably performed in completing the transistor.

    摘要: A semiconductor body has a first portion, a second portion, and an active area located between the first portion and the second portion. The first portion and the second portion are a shallow trench isolation region having an exposed surface extending above the surface of the active area. A first ion implantation is performed at a first angle such that a first shaded area defined by the exposed surface of the first portion and the first angle is exposed to fewer ions than a first unshaded area. A second ion implantation is performed at a second angle such that a second shaded area defined by the exposed surface of the second portion and the second angle is exposed to fewer ions than a second unshaded area.
