摘要： Semiconductor fabrication methods and structures, devices and integrated circuits characterized by enhanced operating performance. The structures generally include first and second source/drain regions formed in a body of a semiconductor material and a channel region defined in the body between the first and second source/drain regions. Disposed in at least one of the first and second source/drain regions are a plurality of plugs each formed from a volume-expanded material that transfers compressive stress to the channel region. The compressively strained channel region may be useful, for example, for improving the operating performance of p-channel field effect transistors (PFET's).

摘要： Methods for selecting semiconducting carbon nanotubes from a random collection of conducting and semiconducting carbon nanotubes synthesized on multiple synthesis sites carried by a substrate and structures formed thereby. After an initial growth stage, synthesis sites bearing conducting carbon nanotubes are altered to discontinue synthesis at these specific synthesis sites and, thereby, halt lengthening of the conducting carbon nanotubes. Synthesis sites bearing semiconducting carbon nanotubes are unaffected by the alteration so that semiconducting carbon nanotubes may be lengthened to a greater length than the conducting carbon nanotubes.
