Description
しかしながら、本発明は、以下の構成に限定されるものではなく、本発明の要旨を変更しない範囲において適宜変更して適用することができる。以下の実施形態において記載する本発明の個々の望ましい構成を2つ以上組み合わせたものもまた本発明である。
図1は、本発明の第1実施形態に係る半導体センサの一例を模式的に示す断面図である。なお、図1に示す各部分の厚さは、図面の明瞭化と簡略化のために適宜に変更されている。他の図面においても同様である。
(1)2層以上100層以下までグラフェンが多層化、もしくは部分的に多層化した炭素系シート材料
(2)多結晶体であり、粒界を有する、上記(1)に記載の炭素系シート材料
(3)さらに部分的に破れが生じており、端部を有する、上記(2)に記載の炭素系シート材料
(4)部分的に元素置換されていたり、ハニカム構造が崩れている上記(1)~(3)のいずれかに記載の炭素系シート材料
(5)酸化グラフェンおよびそれを還元した、還元型酸化グラフェン
(6)リボン状(短冊状)のグラフェン
(7)くるまった形状をしているグラフェン
(8)シート状のグラフェンが筒状になったカーボンナノチューブ
うように絶縁基板11上に形成されている。
本発明の第2実施形態では、レセプターが、酸化膜の表面に存在するスペーサ分子を介して酸化膜の表面に固定されている。スペーサ分子により、酸化膜に表面に配置されるレセプターが酸化膜の表面から離れ自由度を得ることで、レセプターのセンシング能が向上する。また、スペーサ分子が親水性を有する場合は半導体センサの表面の親水性を強化することができる。
本発明の第3実施形態では、酸化膜の表面に、レセプターとともにブロッキング剤が存在する。ブロッキング剤により、半導体センサの表面の親水性が強化される。
本発明の第4実施形態では、半導体シートと酸化膜との間にシード層が設けられている。シード層を設けることにより、酸化膜が均一に成膜され、半導体センサの感度が高まる。
本発明の第5実施形態では、酸化膜が表面に凹凸を有する。酸化膜の表面に設けられた凹凸により、酸化膜の表面積を増やすことができるため、半導体センサの表面の親水性が高まる。また、酸化膜の表面に配置されるレセプターの密度を高くすることができるため、半導体センサの感度が高まる。
本発明の第6実施形態では、酸化膜上のセンシング部以外の部分に絶縁コート層が設けられている。絶縁コート層を設けることにより、センシング部以外の部分の絶縁性が高まるため、半導体センサの信頼性が向上する。また、センシング部以外の部分でターゲット分子が補足されなくなるため、半導体センサの感度が高まる。
本発明の第7実施形態では、ソース電極上およびドレイン電極上に絶縁コート層が設けられ、ソース電極上、ドレイン電極上および絶縁コート層上に半導体シートが配置されている。
本発明の半導体センサは、例えば、バイオセンサとして用いることができる。この場合、具体的な検出対象物質としては、例えば、細胞、微生物、ウイルス、タンパク質、酵素、核酸、低分子生体物質等が挙げられる。
