Description
また、グラフェンをトランジスタに利用する技術が知られている。例えば、グラフェンを電界効果トランジスタ(Field Effect Transistor,FET)のゲートに用い、そのグラフェンにアンモニア等の対象ガスが吸着した時の仕事関数変化に起因した閾値電圧変化によって生じるドレイン電流変化に基づき、対象ガスを検知するガスセンサが提案されている。
また、一観点によれば、上記のような電子デバイスを備える電子機器が提供される。
図1は第1の実施の形態に係る電子デバイスの一例を示す図である。図1には、電子デバイスの要部斜視図を模式的に示している。
ガスセンサは、雰囲気中に含まれる化学物質を検知するもので、様々な測定原理のものがあり、環境測定等に広く使用される。例えば、自動車の排気ガスに含まれる二酸化窒素(NO2)は、その環境基準値が20ppb(parts per billion)〜40ppb程度であり、極めて低濃度の検知が要求される。また、近年、呼気に含まれる化学物質と健康状態との関連が指摘されており、例えば、胃がんと呼気中のアンモニア(NH3)の濃度、喘息と一酸化窒素(NO)の濃度との関連が指摘されている。その診断の閾値は、数十ppb〜数百ppb程度であり、この場合も極めて低濃度の検知が要求される。
図4は第2の実施の形態に係る電子デバイスの一例を示す図である。図4(A)には、電子デバイスの要部断面を模式的に図示している。図4(B)には、ゲート絶縁膜を構成する分子の一例を示している。
半導体基板20には、例えば、シリコン基板が用いられる。半導体基板20内には、その一部の半導体領域21を挟んで対向するようにソース領域22及びドレイン領域23が設けられる。例えば、半導体領域21はp型とされ、ソース領域22及びドレイン領域23はn型とされる。ソース領域22とドレイン領域23との間に介在される半導体領域21が、FETのチャネル領域として機能する。
図5及び図6は第2の実施の形態に係る電子デバイスの形成方法の一例を示す図である。図5(A)〜図5(C)及び図6(A)〜図6(C)にはそれぞれ、電子デバイス形成の各工程の要部断面を模式的に図示している。
より詳しくは、まず、上記のように下層側の絶縁膜31が形成された半導体基板20と、開放容器に入れたSAM膜の原料とが、不活性雰囲気中の密閉容器内に、大気圧下で配置される。SAM膜の原料には、例えば、[3−(N,N−ジメチルアミノ)プロピル]トリメトキシシランが用いられる。このほか、SAM膜の原料には、3−アミノプロピルトリエトキシシラン、トリメトキシ[3−(メチルアミノ)プロピル]シラン等が用いられてもよい。続いて、絶縁膜31が形成された半導体基板20とSAM膜の原料とが入った密閉容器が電気炉内に配置され、数時間程度の加熱処理が行われる。加熱温度は、例えば、100℃とされる。この加熱処理により、SAM膜の原料が絶縁膜31の表面にシランカップリングされる。これにより、絶縁膜31上にSAM膜が形成される。形成されたSAM膜には、各種処理が施される。例えば、エタノール処理、トルエン処理、水酸化カリウム処理、硝酸処理がそれぞれ10分間程度、順次行われる。その後、純水で洗浄され、窒素ブロー処理が行われる。
例えば、上記のような方法により、図5(C)に示すような、ゲート絶縁膜30上にその上層側の絶縁膜32に接するようにグラフェン10が形成された構造が得られる。
電子デバイス1Aは、例えば、ガスセンサとして用いられる。或る雰囲気中に配置された電子デバイス1Aのグラフェン10に、雰囲気中の検知対象成分が吸着すると、その吸着した検知対象成分によってグラフェン10に電荷がドープされ、グラフェン10の仕事関数が変化する。グラフェン10の仕事関数が変化すると、グラフェン10をゲートするFETの閾値電圧が変化する。その結果、所定のバイアス下で、ソース領域22(ソース電極50)とドレイン領域23(ドレイン電極60)との間に流れるドレイン電流が変化する。このようなドレイン電流の変化に基づき、雰囲気中の検知対象成分(その有無や量)の検知が行われる。尚、電子デバイス1Aをガスセンサとして用いる場合のシステム構成については後述する(図9)。
図7は第2の実施の形態に係る電子デバイスの電流電圧特性の説明図、図8は第2の実施の形態に係る電子デバイスの検知感度特性の説明図である。
図9は第2の実施の形態に係る電子デバイスを用いたガスセンサシステムの一例を示す図である。

図11は第4の実施の形態に係る電子デバイスの一例を示す図である。図11には、電子デバイスの要部断面を模式的に図示している。
図12は第5の実施の形態に係る電子デバイスの一例を示す図である。図12には、電子デバイスの要部断面を模式的に図示している。
図13は第6の実施の形態に係る電子デバイスの一例を示す図である。図13には、電子デバイスの要部断面を模式的に図示している。
図14は第7の実施の形態に係る電子デバイスの一例を示す図である。図14には、電子デバイスの要部断面を模式的に図示している。
上記第1〜第7の実施の形態では、FETのチャネル領域を半導体基板20によって実現する例を示したが、これに限らず、各種の膜をFETのチャネル領域の材料として用いることができる。そのような膜としては、アモルファスシリコン膜、ポリシリコン膜、インジウム(In)−ガリウム(Ga)−亜鉛(Zn)−酸素(O)を含む膜(IGZO膜)、酸化亜鉛(ZnO)膜、遷移金属ダイカルコゲナイド膜等が挙げられる。ここでは一例として、遷移金属ダイカルコゲナイドをFETチャネル領域の材料に用いた電子デバイスを、第8の実施の形態として説明する。
図15に示す電子デバイス1Gは、グラフェン10をゲートとするFETのチャネル領域の材料として、遷移金属ダイカルコゲナイド(MX2,M:遷移金属,X:カルコゲン原子)が用いられた構成を有する。
半導体層90に、二硫化モリブデン(MoS2)等の遷移金属ダイカルコゲナイドが用いられる。半導体層90の、対向する両端部に、ソース電極50及びドレイン電極60がそれぞれ接続される。ソース電極50とドレイン電極60との間の半導体層90が、FETのチャネル領域として機能する。
図16及び図17は第8の実施の形態に係る電子デバイスの形成方法の一例を示す図である。図16(A)〜図16(C)及び図17(A)〜図17(B)にはそれぞれ、電子デバイス形成の各工程の要部断面を模式的に図示している。
次に、第9の実施の形態について説明する。
図18に示す電子デバイス1Hは、ゲート絶縁膜30として強誘電体膜が設けられている点で、上記第8の実施の形態で述べた電子デバイス1Gと相違する。
上記第1〜第9の実施の形態で述べた電子デバイス1,1A〜1Gをスイッチング素子として用いる場合、それらは各種電子機器に搭載することができる。例えば、コンピュータ(パーソナルコンピュータ、スーパーコンピュータ、サーバ等)、スマートフォン、携帯電話、タブレット端末、センサ、カメラ、オーディオ機器、測定装置、検査装置、製造装置といった、各種電子機器に搭載することができる。
図19に示すように、例えば上記第6の実施の形態で述べたような電子デバイス1E(図13)が各種電子機器300に搭載(内蔵)される。電子デバイス1Eでは、そのゲート絶縁膜30の上層側の絶縁膜32により、それに接して設けられるグラフェン10の電荷のドーピングが誘起される。所定の材料が用いられた絶縁膜32によってグラフェン10の仕事関数が調整されることで、ゲートの閾値電圧が調整され、スイッチング特性が調整される。これにより、用途に適した高いデバイス性能を有する電子デバイス1Eが実現され、このような電子デバイス1Eを搭載した、高性能の各種電子機器300が実現される。
