    摘要: A transistor includes a semiconductor layer, and a gate dielectric is formed on the semiconductor layer. A gate conductor is formed on the gate dielectric and an active area is located in the semiconductor layer underneath the gate dielectric. The active area includes a graded dopant region that has a higher doping concentration near a top surface of the semiconductor layer and a lower doping concentration near a bottom surface of the semiconductor layer. This graded dopant region has a gradual decrease in the doping concentration. The transistor also includes source and drain regions that are adjacent to the active region. The source and drain regions and the active area have the same conductivity type.

    摘要: A semiconductor-on-insulator (SOI) substrate complementary metal oxide semiconductor (CMOS) device and fabrication methods include a p-type field effect transistor (PFET) and an n-type field effect transistor (NFET). Each of the PFET and the NFET include a transistor body of a first type of material and source and drain regions. The source and drain regions have a second type of material such that an injection charge into the source and drain region is greater than a parasitic charge into the transistor body to decrease parasitic bipolar current gain, increase critical charge (Qcrit) and reduce sensitivity to soft errors.

    摘要: The present invention relates to methods and devices for reducing the threshold voltage difference between an n-type field effect transistor (n-FET) and a p-type field effect transistor (p-FET) in a complementary metal-oxide-semiconductor (CMOS) circuit located on a silicon-on-insulator (SOI) substrate. Specifically, a substrate bias voltage is applied to the CMOS circuit for differentially adjusting the threshold voltages of the n-FET and the p-FET. For example, a positive substrate bias voltage can be used to reduce the threshold voltage of the n-FET but increase that of the p-FET, while a negative substrate bias voltage can be used to increase the threshold voltage of the n-FET but reduce that of the p-FET. Further, two or more substrate bias voltages of different magnitudes and/or directions can be used for differentially adjusting the n-FET and p-FET threshold voltages in two or more different CMOS circuits or groups of CMOS circuits.

    摘要: A method is provided to fabricate a semiconductor device, where the method includes providing a substrate comprised of crystalline silicon; implanting a ground plane in the crystalline silicon so as to be adjacent to a surface of the substrate, the ground plane being implanted to exhibit a desired super-steep retrograde well (SSRW) implant doping profile; annealing implant damage using a substantially diffusionless thermal annealing to maintain the desired super-steep retrograde well implant doping profile in the crystalline silicon and, prior to performing a shallow trench isolation process, depositing a silicon cap layer over the surface of the substrate. The substrate may be a bulk Si substrate or a Si-on-insulator substrate. The method accommodates the use of an oxynitride gate stack structure or a high dielectric constant oxide/metal (high-K/metal) gate stack structure. The various thermal processes used during fabrication are selected/controlled so as to maintain the desired super-steep retrograde well implant doping profile in the crystalline silicon.
