  2. Along with silicon ulsi technology has seen an exponential improvement in virtually any figure of merit, as described by moore ’ s law ; the miniaturization of circuit elements down to the nanometer scale has resulted in structures which exhibt novel physical effects due to the emerging quantum mechanical nature of the electrons, the new devices take advantage of quantum mechanical phenomena that emerge on the nanometer scale, including the discreteness of electrons. laws of quantum mechanics and the limitations of fabrication may soon prevent further reduction in the size of today ’ s conventional field effect transistors ( fet ’ s )

    隨著超大規模集成電路的的發展,半導體硅技術非常好地遵循moore定理發展,電子器件的特徵尺寸越來越小;數集成電路的晶的集成度越來越高,電子器件由微米級進入納米級,量子效應對器件工作的影響變的越來越重要,尺寸小於10nm將出現一些如庫侖阻塞等新特性。量子效應將傳統晶體管fet繼續按照以前的規律繼續減小。在這種情況下,宏觀的器件理論將被替代,可能需要採用新概念的晶體管結構。
