    摘要: A method for forming strained Si or SiGe on relaxed SiGe on insulator (SGOI) is described incorporating growing epitaxial Si1−yGey layers on a semiconductor substrate, implanting hydrogen into a selected Si1−yGey layer to form a hydrogen-rich defective layer, smoothing surfaces by Chemo-Mechanical Polishing, bonding two substrates together via thermal treatments and separating two substrates at the hydrogen-rich defective layer. The separated substrates may have its upper surface smoothed by CMP for epitaxial deposition of relaxed Si1−yGey, and strained Si1−yGey depending upon composition, strained Si, strained SiC, strained Ge, strained GeC, and strained Si1−yGeyC.

    摘要: A method is disclosed for preparing a surface of a Group III-Group V compound semiconductor for epitaxial deposition. The III-V semiconductor surface is treated with boron (B) at a temperature of between about 250° C. and about 350° C. A suitable form for supplying B for the surface treatment is diborane. The B treatment can be followed by epitaxial growth, for instance by a Group IV semiconductor, at temperatures similar to those of the B treatment. The method yields high quality heterojunction, suitable for fabricating a large variety of device structures.

    摘要: A method for forming and the structure of a strained vertical channel of a field effect transistor, a field effect transistor and CMOS circuitry is described incorporating a drain, body and source region on a sidewall of a vertical single crystal semiconductor structure wherein a hetero-junction is formed between the source and body of the transistor, wherein the source region and channel are independently lattice strained with respect to the body region and wherein the drain region contains a carbon doped region to prevent the diffusion of dopants (boron) into the body. The invention reduces the problem of leakage current from the source region via the hetero-junction and lattice strain while independently permitting lattice strain in the channel region for increased mobility via choice of the semiconductor materials.

    摘要: A method for forming strained Si or SiGe on relaxed SiGe on insulator (SGOI) or a SiGe on Si heterostructure is described incorporating growing epitaxial Si1−yGey layers on a semiconductor substrate, smoothing surfaces by Chemo-Mechanical Polishing, bonding two substrates together via thermal treatments and transferring the SiGe layer from one substrate to the other via highly selective etching using SiGe itself as the etch-stop. The transferred SiGe layer may have its upper surface smoothed by CMP for epitaxial deposition of relaxed Si1−yGey, and strained Si1−yGey depending upon composition, strained Si, strained SiC, strained Ge, strained GeC, and strained Si1−yGeyC or a heavily doped layer to make electrical contacts for the SiGe/Si heterojunction diodes.
