Abstract
【選択図】図4
Description
「隣接する」とは、3つ以下の層を間に有する、相互と近接する層を指す。
「導電性」とは、約10−6〜1オーム−cmのバルク電気抵抗率を有する材料を指す。
「一体化する」又は「一体化」とは、受動回路要素若しくは静電容量感知要素を、基材の面の上に直接定置すること、又は配置することを指し、一体化された受動回路要素は、別個の受動回路要素、例えば、基材に接合され、基材に電気的に接続されなければならない(例えば、半田接合又はワイヤー接合される)チップ抵抗器又はチップコンデンサと対照的である。
「受動回路要素」とは、構成の一部として半導体材料を含有しない、電気回路の要素を指す。
「メッシュ」とは、導電性トレースの二次元ネットワーク、例えば、矩形(例えば、正方形)グリッドを生じるように、相互に対して直交して走るトレースを指す。
「導電性トレース」とは、導電性材料のパターン内の細い線状パターン要素、例えば、長さが100マイクロメートルである、幅が2マイクロメートルの導電性の線を指す。
「タッチセンサ若しくはタッチ感知」又は「タッチスクリーン」とは、1つ以上の身体部分(即ち、1本以上の指)で物理的に、又は近接してタッチする(電界を間接的に妨害する)ことによって作動させることができる、センサ要素を指す。
「非導電性」及び「絶縁」は、交換可能に使用され、これらの用語は、実質的に非導電性である材料、例えば、少なくとも106オーム−cm、好ましくは少なくとも108オーム−cm、より好ましくは少なくとも1012オーム−cmのバルク電気抵抗率を有する材料を指す。
L=μon2r=1.2×10−6n2r
であり、式中、nは、回転数であり、rは、半径である。使用される半径は、コイルの中央で測定される。例として、n=6及びr=180μmを使用して、Lは、約0.008マイクロヘンリー(μH)と計算される。より多くのコイルを同様の空間内に定置すると、インダクタ値が増加し得る。例えば、100μmの内側半径で開始して、次いで5μmのワイヤー及び5μmの空間を使用すると、25回転は、約.181μHの値を有するインダクタを生じ得る。
抵抗要素は、ポリエチレンテレフタレート(PET、デラウェア州ウィルミントンのE.I.du Pont de Nemoursから入手可能なmelinex ST504フィルム)フィルム基材の上に、i)熱蒸発によって、PET基材を金属の薄いフィルム(3ナノメートルのクロム接着層、続いて100ナノメートルの銀)でコーティングし、ii)アルキルチオール(オレゴン州ポートランドのTCI Americaから入手可能なn−オクタデカンチオール)自己組織化単層のパターンを銀面の上にマイクロコンタクト印刷(10秒間)し、印刷された自己組織化単層のパターンの一体化された抵抗器を生じるために、金属を湿式化学エッチングすることによって一体化された。湿式化学エッチング液は、20mMの硝酸第二鉄(ウィスコンシン州ミルウォーキーのAldrich Chemical Company)及び30mMのチオ尿素(ウィスコンシン州ミルウォーキーのAldrich Chemical Company)の水溶液であった。
コンデンサ要素は、ポリエチレンテレフタレート(PET、デラウェア州ウィルミントンのE.I.du Pont de Nemoursから入手可能なmelinex ST504)フィルム基材の上に、i)熱蒸発によって、PET基材を金属の薄いフィルム(3ナノメートルのクロム接着層、続いて70ナノメートルの金)でコーティングし、ii)アルキルチオール(オレゴン州ポートランドのTCI Americaから入手可能なn−オクタデカンチオール、又は英国ウェストミッドランド州ウェストブロミッジのRobinson Brothersから入手可能なn−エイコサンチオール)自己組織化単層のパターンを金面の上にマイクロコンタクト印刷(10秒間)し、印刷された自己組織化単層のパターンの一体化されたコンデンサを生じるために、金属を湿式化学エッチングすることによって一体化された。湿式化学エッチング液は、約5体積パーセントの水中に6Nの塩酸、約5体積パーセントの15wt%の過酸化水素水溶液、及び約90体積パーセントの水中に5wt%のチオ尿素の溶液(すべての試薬は、ウィスコンシン州ミルウォーキーのAldrich Chemical Companyから市販されている)の水溶液であった。
