    摘要: An improved semiconductor device, such as a MOSFET with raised source/drain extensions on a substrate with isolation trenches etched into the surface of the substrate . The device has thin first dielectric spacers on the side of a gate and gate oxide and extend from the top of the gate to the surface of the substrate. Raised source/drain extensions are placed on the surface of a substrate, which extend from the first dielectric spacers to the isolation trenches. Thicker second dielectric spacers are placed adjacent to the first dielectric spacers and extend from the top of the first dielectric spacers to the raised source/drain extensions. Raised source/drain regions are placed on the raised source/drain extensions, and extend from the isolation trenches to the second dielectric spacers. The semiconductor device has very shallow source drain extensions which result in a reduced short channel effect.

    摘要: A method for making a ULSI MOSFET includes establishing a gate void in a field oxide layer above a silicon substrate, after source and drain regions with associated source and drain extensions have been established in the substrate. A gate electrode is deposited in the void and gate spacers are likewise deposited in the void on the sides of the gate electrode, such that the gate electrode is spaced from the walls of the void. The spacers, not the gate electrode, are located above the source/drain extensions, such that fringe coupling between the gate electrode and the source and drain extensions is suppressed.
