− 多層構造の一貫性:次の半導電性層、絶縁層および/または導電性層の溶液塗布中に、その下にある層は、次の層の析出のために使用される溶剤によって溶解または膨張されるべきでない。もしも溶剤が下にある層の中に混入された場合、一般的にその層の特性の劣化を引き起こす膨張が生じる。
− 電極の高分解能パターン化:明確に規定された内部接続部およびチャネル長L≦10μmを有するTFTチャネルを形成するために導電体層をパターン化する必要がある。
− TFT回路を製造するために、垂直内部接続領域(ビアホール)は、素子の異なる複数の層における複数の電極を電気的に接続するように形成される必要がある。
− パターン化された導電性ソース−ドレインおよびゲート電極および内部接続。
− 0.01cm2/Vsより大きい荷電キャリア移動性を有する半導電性層および104より大きい高オン−オフ電流スイッチング比。
− 薄膜ゲート絶縁層。
− 不純物およびイオン拡散による意図せぬドーピングから半導電性層および絶縁層を保護する拡散障壁層。
− プリント技術によるゲート電極の高解像度パターンニングを可能とする表面改良層。
− 誘電体層を貫通して内部接続するためのビアホール。
