    摘要: According to one exemplary embodiment, a method for adjusting a transistor model for increased circuit simulation accuracy includes determining a first gate CD offset by matching a C-V test structure having a normalized channel current to an I-V test structure having the normalized channel current. The method further includes utilizing the first gate CD offset to adjust the transistor model for increased circuit simulation. The method also includes determining a second gate CD offset by varying I-V and C-V gate length parameters in the transistor model to cause simulated data from a test circuit to be approximately equal to measured data from the test circuit. The method further includes utilizing the second gate CD offset to adjust the transistor model.

    摘要: A body tie test structure and methods for its manufacture are provided. The transistor comprises a body-tied semiconductor on insulator (SOI) transistor formed in a layer of semiconductor material, the transistor comprising a cross-shaped gate structure with a substantially constant gate length L. An insulating blocking layer enables formation of a spacer region in the layer of semiconductor material separating the source and drain regions from the body tie region. A conductive channel with substantially the same inversion characteristics as the intrinsic transistor body connects the body tie to the intrinsic transistor body through the spacer region.

    摘要: According to one exemplary embodiment, a silicon-on-insulator (SOI) transistor test structure includes a gate situated over a semiconductor body and a doped halo under the gate. The SOI transistor test structure further includes at least two semiconductor body contacts situated on opposing sides of the doped halo, where one or more of the at least two semiconductor body contacts forms a direct electrical contact with the doped halo, thereby increasing current flow to the doped halo to facilitate measuring body-effect in the SOI transistor test structure.

    摘要: Strained silicon is grown on a dielectric material in a trench in a silicon germanium layer at a channel region of a MOSFET after fabrication of other MOSFET elements using a removable dummy gate process to form an SOI MOSFET. The MOSFET is fabricated with the dummy gate in place, the dummy gate is removed, and a trench is formed in the channel region. Dielectric material is grown in the trench, and strained silicon is then grown from the silicon germanium trench sidewalls to form a strained silicon layer that extends across the dielectric material. The silicon germanium sidewalls impart strain to the strained silicon, and the presence of the dielectric material allows the strained silicon to be grown as a thin fully depleted layer. A replacement gate is then formed by damascene processing.
