    摘要: A FinFET device employs strained silicon to enhance carrier mobility. In one method, a FinFET body is patterned from a layer of silicon germanium (SiGe) that overlies a dielectric layer. An epitaxial layer of silicon is then formed on the silicon germanium FinFET body. A strain is induced in the epitaxial silicon as a result of the different dimensionalities of intrinsic silicon and of the silicon germanium crystal lattice that serves as the template on which the epitaxial silicon is grown. Strained silicon has an increased carrier mobility compared to relaxed silicon, and as a result the epitaxial strained silicon provides increased carrier mobility in the FinFET. A higher driving current can therefore be realized in a FinFET employing a strained silicon channel layer.

    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.

    摘要: 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.

    摘要: 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.
