    Abstract: 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.

    Abstract: A dual doped CMOS gate structure utilizes a nitrogen implant to suppress dopant inter-diffusion. The nitrogen implant is provided above standard trench isolation structures. Alternatively, an oxygen implant can be utilized. The use of the implant allows an increase in packing density for ultra-large-scale integrated (ULSI) circuits. The doping for N-channel and P-channel active regions can be completed when the polysilicon gate structures are doped.

    Abstract: An ultra-large-scale integrated (ULSI) circuit includes MOSFETs which have different threshold voltages and yet have the same channel characteristics. The MOSFETs include gate structures with a polysilicon material. The polysilicon material is implanted with lower concentrations of germanium where lower threshold voltage MOSFETs are required. Over a range of 0-60% concentration of germanium, the threshold voltage can be varied by roughly 240 mV.

    Abstract: A method for fabricating short channel field effect transistors with dual gates and with a gate dielectric having a high dielectric constant. The field effect transistor is initially fabricated to have a sacrificial gate dielectric and a dummy gate electrode. Any fabrication process, such as an activation anneal or a salicidation anneal of the source and drain of the field effect transistor, using relatively high temperature is performed with the field effect transistor having the sacrificial gate dielectric and the dummy gate electrode. The dummy gate electrode and the sacrificial gate dielectric are etched from the field effect transistor to form a gate opening. A layer of dielectric with high dielectric constant is deposited on the side wall and the bottom wall of the gate opening, and a crystallization enhancing layer is deposited on the bottom wall of the gate opening. Amorphous gate electrode material, such as amorphous silicon, is deposited to fill the gate opening after the crystallization enhancing layer has been deposited. Dual gates for both an N-channel field effect transistor and a P-channel field effect transistor are formed by doping the amorphous gate electrode material with an N-type dopant for an N-channel field effect transistor, and by doping the amorphous gate electrode material with a P-type dopant for a P-channel field effect transistor. The amorphous gate electrode material in the gate opening is then annealed at a relatively low temperature, such as 500° Celsius, using an enhanced crystallization process to convert the amorphous gate electrode material, such as amorphous silicon, into polycrystalline gate electrode material, such as polycrystalline silicon. Thus, relatively low temperatures are used in the present invention to preserve the integrity of the gate dielectric having the high dielectric constant.

    Abstract: Low resistance contacts are formed on source/drain regions and gate electrodes by selectively depositing a reaction barrier layer and selectively depositing a metal layer on the reaction barrier layer. Embodiments include selectively depositing an alloy of cobalt and tungsten which functions as a reaction barrier layer preventing silicidation of a layer of nickel or cobalt selectively deposited thereon. Embodiments also include tailoring the composition of the cobalt tungsten alloy so that a thin silicide layer is formed thereunder for reduced contact resistance.
