    摘要: A method for forming a group of structures in a semiconductor device includes forming a conductive layer on a substrate, where the conductive layer includes a conductive material, and forming an oxide layer over the conductive layer. The method further includes etching at least one opening in the oxide layer, filling the at least one opening with the conductive material, etching the conductive material to form spacers along sidewalls of the at least one opening, and removing the oxide layer and a portion of the conductive layer to form the group of structures.

    摘要: A method of forming a specialized channel region removes a sacrificial gate material and provides a semiconductor implant though the recess associated with the remove sacrificial gate material. The process can be utilized to form a silicon germanium layer in the channel region having a sharp profile in the vertical direction. Further, the silicon germanium layer can be ultra-thin. The silicon germanium channel region has increased charge mobility with respect to conventional channel regions.

    摘要: MOSFETs are fabricated with accurately defined, high and uniformly concentrated source/drain regions and extensions employing plural, sequential pre-amorphizing, implanting and laser thermal annealing steps with intervening spacer removal. Embodiments include forming sidewall spacers on a gate electrode, sequentially pre-amorphizing, ion implanting and laser thermal annealing to form deep source/drain regions, removing the sidewall spacers, and then sequentially pre-amorphizing, ion implanting and laser thermal annealing to form shallow source/drain extensions.

    摘要: A semiconductor device with reduced hot carrier injection and punch through is formed with a dual gate electrode comprising edge conductive portions, a central conductive portion, and dielectric sidewall spacers formed between the edge conductive portions and central conductive portion. The edge conductive portions provide high potential barriers against the active regions, thereby reducing threshold voltage roll off and leakage current.

    摘要: A thin filmed fully-depleted silicon-on-insulator (SOI) metal oxide semiconductor field defect transistor (MOSFET) utilizes a local insulation structure. The local insulative structure includes a buried silicon dioxide region under the channel region. The MOSFET body thickness is very small and yet silicon available outside of the channel region and buried silicon dioxide region is available for sufficient depths of silicide in the source and drain regions. The buried silicon dioxide region can be formed by a trench isolation technique or a LOCOS technique.

In addition, a gate electrode material is deposited on the gate dielectric material to surround the pillar at the top surface and the first and second side surfaces of the pillar and to fill the recess, for the gate length of the pillar. A drain and source dopant is implanted into exposed regions of the pillar to form a drain of the field effect transistor on a first side of the gate electrode material along the length of the pillar and to form a source of the field effect transistor on a second side of the gate electrode material along the length of the pillar.
