    摘要: Methods are provided for the fabrication of multiple finger transistors. A method comprises forming a layer of gate-forming material overlying a semiconductor substrate and forming a layer of dummy gate material overlying the layer of gate-forming material. The layer of dummy gate material is etched to form a dummy gate and sidewall spacers are formed about sidewalls of the dummy gate. The dummy gate is removed and the layer of gate-forming material is etched using the sidewall spacers as a mask to form at least two gate electrodes.

    摘要: A fully depleted SOI FET and methods of formation are disclosed. The FET includes a layer of semiconductor material disposed over an insulating layer, the insulating layer disposed over a semiconductor substrate. A source, a drain and a body disposed between the source and the drain are formed from the layer of semiconductor material.

    摘要: When Tilted Channel Implant (TCI) is performed on transistor precursor structures having an etch-defined gate length (L2M) and a trim-defined sidewall thickness (SwM), mass production deviations may cause errors and cause shifts in the lateral placement and implant depth of TCI dopants. Countering adjustments to TCI dosage and TCI energy are automatically made in accordance with the invention. In one embodiment, a first linear or quasi-linear interpolation function is used having form: Energya=E0*(1+&bgr;*eSw/SwT), where multiplying factor &bgr; may either be a constant or a function of normalized sidewall error value, eSw/SwT. In the same embodiment, a second linear or quasi-linear interpolation function is used having form: Dosea=Dose0*(1+&agr;(L2T−L2M)/L2T), where multiplying factor &agr; is a constant or a function of normalized gate length error value, (L2T−L2M)/L2T.

    摘要: In a method of forming a metal gate of a semiconductor device, a substrate is provided, which includes a substrate body covered by a dielectric layer. A metal body having top and side surface is provided on the dielectric layer. A self-assembled monolayer is provided over the top and side surfaces of the metal body, and has an ordered region covering the top surface of the metal body and disordered regions covering the side surfaces of the metal body. The resulting structure is etched, the disordered regions of the self-assembled monolayer allowing etching of the side surfaces of the metal body while the ordered region of the self-assembled monolayer substantially blocks etching of the top surface of the metal body.
