Abstract
【解決手段】 低い接触抵抗を示す新しいクラスの高密度の垂直型Fin−FETデバイスが説明される。これらの垂直型Fin−FETデバイスは、トランジスタ本体として働く垂直方向のシリコン「フィン」(12A)を有する。ドープされたソース領域及びドレイン領域(26A、28A)が、それぞれフィン(12A)の下部及び上部内に形成される。ゲート(24A、24B)が、フィンの側壁に沿って形成される。適切なバイアスがゲート(24A、24B)に印加されると、電流は、ソース領域(26A)とドレイン領域(28A)との間で、フィン(12A)を通して垂直方向に流れる。pFET、nFET、マルチ・フィン、シングル・フィン、マルチ・ゲート、及びダブルゲートの垂直型Fin−FETを同時に形成するための統合プロセスが説明される。
