Description
(a)絶縁層と;
(b)ゲート電極と;
(c)半導体層と;
(d)ソース電極と;
(e)ドレイン電極とを備える薄膜トランジスタが得られ、
絶縁層、ゲート電極、半導体層、ソース電極、ドレイン電極は、ゲート電極と半導体層が両方とも絶縁層と接触し、ソース電極とドレイン電極が両方とも半導体層に接触している限り、任意の順序であり、
ソース電極、ドレイン電極、ゲート電極のうち、少なくとも1つが、有機アミン化合物によって安定化された金属ナノ粒子を含む溶液を与えることと、有機アミンで安定化された組成物を基板表面に析出させることと、この基板表面にある有機アミンで安定化された組成物を、約70℃〜約200℃の温度まで加熱し、基板表面に導電性の部品を形成させることとによって作られてもよい。
米国特許出願第12/369,861号にすでに開示されている方法を用い、3つの異なるバッチで製造した銀ナノ粒子を用い、組成物を製造した。銀ナノ粒子の3つのバッチであるバッチ1、バッチ2、バッチ3を、比較例1〜3および実施例1〜3の調製でそれぞれ用いた。銀ナノ粒子粉末の3つのバッチを同じ様式で合成し、再現性を評価した。3バッチすべての銀ナノ粒子には、銀がほぼ85重量%含まれていた。
銀ナノ粒子粉末と、ISOPAR Gおよびテルピネオールを比率2:1で混合した溶媒混合物とを混合することによって、組成物を調製した。銀ナノ粒子は、銀配合物の50重量%であった。銀ナノ粒子を溶媒に混合した後、組成物を1μmシリンジフィルタで濾過した。10pLカートリッジを取り付けたDMP−2800インクジェットプリンタを用い、組成物を印刷した。印刷し、熱によってアニーリングした後、線の形状を表面形状測定装置を用いて特性決定した。
比較例と同じバッチから製造した銀ナノ粒子粉末を混合することによって、組成物を調製した。しかし、組成物の調製は、以下に記載しているように異なっていた。使用した溶媒は、デカヒドロナフタレンであった。デカヒドロナフタレンは、以下のハンセン溶解度パラメータを有している。Hansen Solubility Parameters:A User’s Handbook referenceからわかるように、分散パラメータは18.0MPa0.5であり、極性パラメータは0.0MPa0.5であり、水素結合パラメータは0.0MPa0.5である。銀ナノ粒子は、40重量%保持されていた。銀ナノ粒子を溶媒内で混合した後、組成物を1μmシリンジフィルタで濾過した。10pLカートリッジを取り付けたDMP−2800インクジェットプリンタを用い、組成物を印刷した。印刷し、熱によってアニーリングした後、線の形状を表面形状測定装置を用いて特性決定した。
