以下では、図2~図3Cを参照して、本実施形態に係るトランジスタの構成について説明する。図2は、本実施形態に係るトランジスタの構成を示す模式的な斜視図である。
次に、図4A~図4Dを参照して、本実施形態に係るトランジスタ100の製造方法について説明する。図4A~図4Dは、本実施形態に係るトランジスタ100の製造方法の一工程を説明する模式的な斜視図である。
続いて、図5A~図5Cを参照して、本開示の第2の実施形態に係るトランジスタ100について説明する。図5Aは、本実施形態に係るトランジスタの構成を示す模式的な透過上面図である。図5Bは、チャネル領域の中央部にて、半導体層112の延伸方向と直交する面でトランジスタ100を切断した縦断面図である。図5Cは、チャネル領域の一方の端部にて、半導体層112の延伸方向と直交する面でトランジスタ100を切断した縦断面図である。
次に、図6A~図6Cを参照して、本開示の第3の実施形態に係るトランジスタ100について説明する。図6Aは、本実施形態に係るトランジスタの構成を示す模式的な透過上面図である。図6Bは、チャネル領域の中央部にて、半導体層113の延伸方向と直交する面でトランジスタ100を切断した縦断面図である。図6Cは、チャネル領域の一方の端部にて、半導体層113の延伸方向と直交する面でトランジスタ100を切断した縦断面図である。
(4.1.ESD保護回路への適用)
本開示の各実施形態に係るトランジスタ100は、例えば、内部回路の静電気(Electro-Static Discharge:ESD)による破壊を防止するESD保護回路内のトランジスタに適用することができる。図7を参照して、本実施形態に係るトランジスタ100が適用され得るESD保護回路の例について説明する。図7は、本実施形態に係るトランジスタ100が適用され得るESD保護回路の一例を示す回路図である。
本開示の各実施形態に係るトランジスタ100は、様々の電子機器に搭載される回路に内の素子に適用することができる。続いて、図8A~図8Cを参照して、本実施形態に係るトランジスタ100が適用され得る電子機器の例について説明する。図8A~図8Cは、本実施形態に係るトランジスタ100が適用され得る電子機器の一例を示す外観図である。
以上にて説明したように、本開示の一実施形態に係るトランジスタ100は、半導体層110の形状をチャネル領域の中央部と端部とで変更することによって、GIDL電流の増加を抑制しつつ、トランジスタ100全体のスレッショルド電圧を高くすることができる。したがって、すなわち、本実施形態に係るトランジスタ100は、半導体層110の形状を制御することで、オフ電流を低減させる所望のトランジスタ特性を得ることが可能である。
