Description
まず、トランジスタ動作特性の評価指標について説明する。
本発明に係わるTFT素子の第1実施例を図4を用いて説明する。
活性層を除いては上記実施例1と同様の構成とした。本比較例では活性層11として、N添加していないIn−Zn−O膜を形成した。なお、本比較例においても、活性層の材料の原子組成比率依存性を検討するために、成膜にコンビナトリアル法を用いている。
活性層を除いては上記実施例1と同様の構成とした。本比較例では活性層11として、N添加したIn−Zn−O膜を形成した。なお、本比較例においても、活性層の材料の原子組成比率依存性を検討するために、成膜にコンビナトリアル法を用いている。
本実施例で得られたN添加In−Zn−O活性層について、光吸収スペクトルの解析を行ったところ、上記N添加酸化膜の禁制帯エネルギー幅はInの原子組成比率に依存して約2.7eVから2.9eVの範囲の値を示していた。比較例1のIn−Zn−O膜では禁制帯エネルギー幅が上記と同様に約2.7から2.9eVの範囲、一方比較例2の酸窒化物半導体では約2.3−2.4eVの値を示している。この結果、窒素の原子組成比率(N/(N+O))が大きくなるに従い、可視域での受光感度が増加してしまうことが分かった。
図6は、本実施例で作製したTFT素子を室温下で測定した時の、Vd=6VにおけるId−Vg特性(トランスファ特性)を示したものである。
本発明に係わるTFT素子の第2実施例を図4を用いて説明する。
活性層を除いては上記実施例1と同様の構成とした。本比較例では活性層11として、N添加していないIn−Zn−Ga−O膜を形成した。なお、本比較例においても、活性層の材料の原子組成比率依存性を検討するために、成膜にコンビナトリアル法を用いている。
本実施例で得られたN添加In−Zn−Ga−O活性層について、光吸収スペクトルの解析を行った。その結果、上記N添加酸化膜の禁制帯エネルギー幅は金属の原子組成比率に依存して約2.8eVから3.1eVの範囲の値を示していた。そして実施例1のN添加In−Zn−O膜よりも若干高い値、また比較例3のIn−Zn―Ga−O膜と同程度の値を示していた。
本実施例2において、最も良好なトランジスタ特性が得られたのは、Inの原子組成比率(In/(Zn+In))が約40原子%、全原子数に対するGaの原子組成比率が0.4原子%の時であった。この時、オン電流は比較的大きい値を示しており、Vg=10Vの時には、Id=4×10−4A程度の電流が流れていることがわかった。オフ電流はId=1×10−13A程度、しきい電圧は約2.3Vであり、実施例1と比べてオフ電流が低く、しきい電圧も大きいことが分かった。またこの時、TFTはノーマリーオフ特性を示していた。出力特性から電界効果移動度およびS値を算出したところ、それぞれ約14.4cm2/Vsおよび約0.3V/decと、実施例1で得られた値とほぼ同程度の良好な特性が得られた。上記結果は比較例3で作製したTFTにおいても同様に観測され、微量のGa添加によって、高い電界効果移動度を保ったまま、低いオフ電流やノーマリーオフ特性が実現されることが分かった。
