Description
図1(a)は、第1の実施の形態に係るFinFETの構成図である。
図3は、第2の実施の形態に係るFinFETの構成図であり、第1の実施の形態と同一部分には同一符号が付されている。第2の実施の形態は、SOI(Silicon On Insulator)基板構造のFinFETであり、基板の構造が第1の実施の形態と異なる。
図4は、第3の実施の形態に係るFinFETの構成図であり、第1の実施の形態と同一部分には同一符号が付されている。第3の実施の形態は、フィン20、21の上面に絶縁層22、23が形成されず、フィン20、21の上面もチャネル領域24、25として利用されるトライゲート型のFinFETであり、その部分のみが第1の実施の形態と異なる。
図5は、第4の実施の形態に係るFinFETの構成図であり、第1の実施の形態と同一部分には同一符号が付されている。第4の実施の形態は、基板がSOI型で、ゲートがトライゲート型であり、その部分のみが第1の実施の形態と異なる。よって、第4の実施の形態は、第1の実施の形態より、動作速度の向上及び低消費電力化と、FETがOFF時のリーク電流を減らす事が可能となる。なお、ゲート電極30、埋め込み部材32等の部分は第1の実施の形態と同一であるため、フィン20、21内部のチャネル領域24、25に対して応力をかける事ができ、第1の実施の形態と同様の効果を得る事ができる。
図8(a)は、第5の実施の形態に係るFinFETの構成図であり、第1の実施の形態と同一部分には同一符号が付されている。第5の実施の形態は、埋め込み部材32がメタルであり、更に、図8(a)に示すように埋め込み部材32がフィン20、21の側面に形成されるゲート酸化膜26の表面まで形成されており、その部分のみが第1の実施の形態と異なる。
図9(a)は、第6の実施の形態に係るFinFETの構成図であり、第1の実施の形態と同一部分には同一符号が付されている。第6の実施の形態は、ゲートがトライゲート型であり、その部分のみが第5の実施の形態と異なる。
