“…1) are now widely recognized as one of the most promising solutions for meeting the roadmap requirements in the deca-nanometer scale (Park & Colinge, 2002). A wide variety of architectures, including planar Double-Gate (DG) (Frank et al, 1992;Harrison et al, 2004), Vertical Double-Gate, Triple-Gate (Tri-gate) (Guarini et al, 2001;Park & Colinge, 2002), FinFET (Choi et al, 2001;Kedzierski et al, 2002), Omega-Gate (Ω -Gate) (Park et al, 2001), Pi-Gate (π -Gate) (Yang et al, 2002), ∆-channel SOI MOSFET (Jiao & Salama, 2001), DELTA transistor (Hisamoto et al, 1989), Gate-All-Around (GAA) (Colinge et al, 1990;Park & Colinge, 2002), Rectangular or Cylindrical nanowires www.intechopen.com Numerical Simulations -Applications, Examples and Theory 68 (Jimenez et al, 2004), has been proposed in the literature. These structures exhibit a superior control of short channel effects resulting from an enhanced electrostatic coupling between the conduction channel and the surrounding gate electrode.…”
