Patent ID: 8350343

Claim:
A computer-aided design method comprising: accessing, by a computer, a first design structure in a hardware description language (HDL) format, said first design structure being embodied in a non-transitory machine readable medium; and, using, by said computer, said first design structure in a design process in conjunction with design automation tools to generate a second design structure, said second design structure comprising all information required by a manufacturer to produce a field effect transistor such that said field effect transistor comprises: a substrate; a semiconductor body on said substrate and having a top surface and opposing sidewalls; and isolation regions positioned laterally adjacent to said opposing sidewalls, said semiconductor body further comprising a channel region comprising edge portions adjacent to said isolation regions and a central portion between said edge portions, said edge portions comprising a first semiconductor material with a first band structure, and said central portion comprising a second semiconductor material different from said first semiconductor material and having a second band structure different from said first band structure.
