    摘要: A narrow groove is formed over a substrate. To form such a narrow groove, a first material is formed over a substrate, the first material having a sidewall. A spacer is formed abutting the sidewall. Subsequently a second material is formed adjacent to the spacer. The spacer is removed leaving a groove between the first material and second material. In one embodiment, the groove is filled with material for a narrow feature, such as a gate, and the first material and second material are removed. As a result a gate or other narrow feature is formed having a length defined by the width of a spacer. In another embodiment, an implant is performed through the small groove, resulting in a small localized implant.

    摘要: A semiconductor device is provided with semiconducting sidewall spacers used in the formation of source/drain regions. The semiconducting sidewall spacers also reduce the possibility of suicide shorting through shallow source/drain junctions. Embodiments include doping the semiconducting sidewall spacers so that they serve as a source of impurities for forming source/drain extensions during activation annealing.

    摘要: An ultra-low thermal budget process is provided for channel implant by using a reverse process sequence where a conventional MOS transistor is formed without the channel implant. The originally deposited polysilicon gate is removed, a nitride film deposition and etch is used to form a nitride spacer with a predetermined configuration, and a self-aligned channel implant is performed. After the channel implantation, anneal and super-retrograded doping, the nitride spacer and the gate oxide are removed for subsequent regrowth of a second gate oxide and a polysilicon deposition to form a second polysilicon gate.

    摘要: Impurities are formed in the active region of a semiconductor substrate by diffusion from a gate electrode sidewall spacer. A gate electrode is formed on a semiconductor substrate with a gate dielectric layer therebetween. Sidewall spacers are formed on the side surfaces of the gate electrode. Dopant atoms are subsequently introduce to transform the spacers into solid dopant sources. Dopant atoms are diffused from the spacers into the semiconductor substrate to form first doped regions.

    摘要: A process in accordance with the invention minimizes the number of heat steps to which an source-drain extension region is exposed, thus minimizing source-drain extension region diffusion and allowing more precise control of source-drain extension region thickness over conventional processes. In accordance with the invention, spacers are formed abutting the gate and then heavily doped source and drain regions are formed. The gate and source and drain regions are silicided. The spacers are subsequently removed and source-drain extension regions are then formed. In one embodiment of the invention, a laser doping process is used to form the source-drain extension regions.

    摘要: A semiconductor device having reduced hot carrier degradation is achieved by doping the semiconductor substrate and gate oxide with deuterium. A conventional semiconductor device is formed with sequentially deposited metal layers and dielectric layers and a topside protective dielectric layer deposited thereon. Deuterium is introduced to the semiconductor device by using deuterium-containing reactants in at least one of the semiconductor manufacturing steps to passivate dangling silicon bonds at the silicon/oxide interface region.
