    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 an integrated circuit on an insulating substrate is described comprising the steps of forming a semiconductor layer on a seed wafer substrate containing an at least partially crystalline porous release layer, processing the semiconductor layer to form a “transferable” device layer containing at least one semiconductor device, and bonding said transferable device layer to a final, insulating substrate before or after separating said device layer from the seed wafer substrate. A second method, for separating a semiconductor layer from a seed wafer substrate, is described wherein an at least partially crystalline porous layer initially connecting the semiconductor layer and seed wafer substrate is split or broken apart by the steps of (i) introducing a fluid including water into the pores of said porous layer, and (ii) expanding said fluid by solidifying or freezing to break apart the porous layer. The at least partially crystalline porous layer may incorporate at least one porous silicon germanium alloy layer alone or in combination with at least one porous Si layer. Also described is an integrated circuit comprising the transfered device layer described above.

    摘要: Analysis of residual gases from a process for depositing a film containing silicon on a crystalline silicon surface to determine partial pressure of hydrogen evolved during deposition develops a signature which indicates temperature and/or concentration of germanium at the deposition surface. Calibration and collection of hydrogen partial pressure data at a rate which is high relative to film deposition rate allows real-time, in-situ, non-destructive determination of material concentration profile over the thickness of the film and/or monitoring the temperature of a silicon film deposition process with increased accuracy and resolution to provide films of a desired thickness with high accuracy.

    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.
