Description
この領域において、2つの異なった手法が原則的に使用される:
FETは3つの接続部がある:
・ソース
・ゲート
・ドレイン。
本発明によれば、用語「FET」は、一般的に次のタイプの電界効果トランジスタを包含する:
・接合型電界効果トランジスタ(JFET)
・ショットキー電界効果トランジスタ(MESFET)
・金属酸化膜半導体FET(MOSFET)
・高電子移動度トランジスタ(HEMT)
・イオン感応性電界効果トランジスタ(ISFET)
・薄膜トランジスタ(TFT)。
酸化亜鉛の薄層用に用いられる出発化合物は、本発明によれば、オキシマート配位子を含む亜鉛錯体である。配位子は、水溶液中の塩基の存在下で、ヒドロキシアミンまたはアルキルヒドロキシアミンと、アルファ−ケト酸またはオキソカルボン酸との縮合により合成される。前駆体または亜鉛錯体は、室温で、亜鉛塩、例えば、硝酸亜鉛の添加後に生じる。
・硬質またはフレキシブル導電基板、あるいは導電層を有する絶縁体基板(ゲート)
・絶縁体
・少なくとも1つの電極(ドレイン電極)
・少なくとも1つの、アルカリ金属およびアルカリ土類金属を含まない、絶縁性および/または半導体性および/または導電性特性を有し、本発明による前駆体から得られる酸化亜鉛層。
半導体酸化亜鉛層は、スピンコーティングにより基板に適用される。
電極は、フレキソ印刷/グラビア印刷、インクジェット印刷、および気相または液相からの蒸着技術により、構造的に適用される。
本発明によれば、30Vより小さいFETしきい電圧が測定された。
a)本発明による有機金属亜鉛錯体の前駆体溶液を、任意で1回または2回以上、積層する方法で、実現される電子構造に対応して、ディップコーティング、スピンコーティングまたはフレキソ印刷/グラビア印刷により、基板に適用する、
b)酸化亜鉛層または表面の形成を伴って、空気中または酸素雰囲気中で、適用された前駆体の焼成または乾燥をする、
c)適用された電子構造が、最終的に、絶縁層で密閉されることができ、接点を備え、完了する、
ことを特徴とする。
本発明によれば、前駆体溶液の、ディップコーティング、スピンコーティング、およびインクジェット印刷またはフレキソ印刷/グラビア印刷などの方法による基板への適用は、当業者には既知であり(M.A. Aegerter, M. Menning; Sol-Gel Technologies for Glass Producers and Users, Kluwer Academic Publishers, Dordrecht, Netherlands, 2004参照)、本発明に従うと、インクジェット印刷またはフレキソ/グラビア印刷が好ましい。
重炭酸テトラメチルアンモニウム(22.94g、120mmol)を、水20ml中の2−オキソプロパン酸(=ピルビン酸)(5.28g、60mmol)およびメトキシルアミンヒドロクロリド(5.02g、60mmol)に、撹拌しながら少量ずつ加える。目で確認できるガスの発生が完了したところで、混合物をさらに2時間撹拌する。亜硝酸亜鉛六水和物(8.92g、30mmol)を続いて加え、4時間後、混合物を5℃まで冷却する。生じた白色沈殿物をろ過し、熱水から再結晶させる。収量5.5g(56.7%)。
例1に従って調製された、ビス[2−(メトキシイミノ)プロパノエート]亜鉛を、ガラス製、セラミック製、PETなどのポリマー製の基板に、スピンコーティング(または、ディップコーティング、またはインクジェット印刷でもよい)により適用する。亜鉛錯体を、続いて、空気中で2時間、150℃の温度において加熱する(図1参照)。このようにして得た酸化亜鉛フィルムは、均一で、亀裂がなく、無孔の表面形態を示す。層は酸化亜鉛結晶からなり、その大きさは焼成温度に依存する。それらは半導体特性を有する。
例1に従って調製された、ビス[2−(メトキシイミノ)プロパノエート]亜鉛を、ガラス製、セラミック製、PETなどのポリマー製の基板に、スピンコーティング(または、ディップコーティング、またはインクジェット印刷でもよい)により適用する。亜鉛錯体を、続いて、空気中で、Feアークランプからの、1時間のUV光照射(照射強度 150mW/cm2から200mW/cm2)により、酸化亜鉛に変換する。このようにして得た酸化亜鉛被膜は、例2のように、均一で、亀裂がなく、無孔の表面形態を示し、さらに、極めて低い表面粗さを有する。層は酸化亜鉛結晶からなり、例2のような、同程度の半導体特性を有する。
全ての場合において、2−メトキシエタノール中で、ビス[2−(メトキシイミノ)プロパノエート]亜鉛の10重量%溶液が使用される。
ディップコーティング:引上げ速度 約1mm/秒。用いられる基板は、76×26mmガラスプレートである。
スピンコーティング:スピンコーティングには、溶液150μlが基板に適用される。使用される基板は、20×20mm石英または15×15mmシリコン(FET製造用金電極を備えた)である。継続時間および速度に選択されるパラメータは、予備速度の1500rpmにおいて10秒、および最終速度の2500rpmにおいて20秒である。
インクジェット印刷:Dimatrix DMP 2811プリンターにより行われる。
本発明は、以下のさらなる詳細において、いくつかの実施例に関して説明される(図1から4参照)。
図1:ガラス基板上でのディップコーティングによる、メトキシエタノール中のビス[2−(メトキシイミノ)プロパノエート]亜鉛を含み、X線光電子分光法(XPS)による種々の反応時間を使用して、150℃において処理された、本発明に記載の被膜の分析を示す図である。XPSスペクトルにより、サンプル中に存在する元素およびそれらの酸化状態についての、および混合比についての情報が得られる。したがって、十分な処理継続時間後、被膜中に酸化亜鉛が存在することを示すことができる。有機不純物(例えば、炭素および窒素)は、手法の検出限界以下の約0.2mol%である。
