| Outline of Final Research Achievements |
This research aims at the low voltage operation of integrated circuits by beyond CMOS and conventional CMOS circuits. The low voltage circuits consist of silicon nanowire transistors, and a room temperature operating single electron transistor is adopted as beyond CMOS. The gate voltage of the Coulomb oscillation peak is as low as 0.45V and the supply voltage of nanowire transistor circuits is 2V. The tiny current of the Coulomb oscillations was amplified and converted to the amplitude of 0.8V by the current-voltage conversion circuits. From the results, the low voltage operation of integrated circuits by room temperature operating single electron transistor and conventional MOS transistors has been demonstrated.

トランジスタの微細化による従来の大規模集積回路の性能向上が困難になりつつある状況において，従来デバイスと異なる原理で動作するいわゆるBeyond CMOSの研究が進んでいるが，従来のMOS回路との融合に関する研究は，その作製が困難なことからほとんど進んでこなかった．今回，室温動作の単電子トランジスタとナノワイヤトランジスタによる融合回路の低電圧動作が示されたことで，将来の集積エレクトロニクスの新しい方向性が実証されたということができ，学術的意義および社会的意義は大きい．
