Abstract
Description
本發明係關於一種包含小分子半導體化合物及非導體聚合物之薄膜半導體,關於含有該化合物、該聚合物及溶劑之溶液,及關於該溶液用以生長大面積結晶半導體薄膜之用途。
有機場效電晶體(OFET)為基於低成本及環境友好半導體材料之用於下一代電子開關的有力候選者,該等半導體材料亦為輕質且可撓的。用於新工業應用之大面積電子器件尤其需要經溶液處理之高效能場效器件,其經由使用習知矽技術尚未考慮到。與習知真空方法相比,諸如印刷之方法能實現簡單的高產量製造,歸因於必需之巨大真空腔室,習知真空方法對於大面積器件為不具有成本效益的。可容易地將諸如旋轉塗佈及滴落塗佈之習知技術應用於大面積器件製造。然而,基於聚合物或可溶小分子半導體之OFET的效能仍然無法令人滿意;針對經溶液處理之OFET所報導的典型載體遷移率保持為約0.1cm2 V-1 s-1。晶粒界及隨機分子定向之存在可妨礙電荷傳輸。
為了改進分子對準中的週期性,最近已提出若干溶液方法用於生長單晶有機半導體膜(H.Minemawari,T.Yamada,H.Matsui,J.Tsutsumi,S.Haas,R.Chiba,R.Kumai,及T.Hasegawa:Nature 475(2011)364;J.Soeda,T.Uemura,Y.Mizuno,A.Nakao,Y.Nakazawa,A.
Facchetti,及J.Takeya:Adv.Mater.23(2011)3681;G.Giri,E.Verploegen,S.C.B.Mannsfeld,S.Atahan-Evrenk,D.H.Kim,S.Y.Lee,H.A.Becerril,A.Aspuru-Guzik,M.F.Toney,及Z.Bao:Nature 480(2011)504;K.Sakamoto,J.Ueno,K.Bulgarevich,及K.Miki:Appl.Phys.Lett.100(2012)123301)。T.Uemura,Y.Hirose,M.Uno,K.Takimiya,及J.Takeya:Appl.Phys.Express 2(2009)111501及K.Nakayama,Y.Hirose,J.Soeda,M.Yoshizumi,T.Uemura,M.Uno,W.Li,M.J.Kang,M.Yamagishi,Y.Okada,E.Miyazaki,Y.Nakazawa,A.Nakao,K.Takimiya,及J.Takeya:Adv.Mater.23(2011)1626描述一種用於產生高度結晶有機半導體膜之方法,該方法使經溶液處理之薄膜電晶體(TFT)的載體遷移率增加一個以上數量級,達到5-10cm2 V-1 s-1。該方法使用邊緣控制附著液滴之形狀,使得液體之厚度隨著距固體邊緣之距離增大而逐漸減小。此方法經由溶劑之非對稱蒸發控制晶體生長的方向,且允許形成連續的均勻結晶膜。邊緣鑄造膜為高度結晶的,其引起極高之遷移率。然而,藉由此技術製備之晶體並不會生長到次毫米尺寸以上,因為當全部溶劑都蒸發時製程結束。因此,該方法並不適用於溶液方法通常最適合的大面積電子器件。
J.Soeda,T.Uemura,T.Okamoto,C.Mitsui,M.Yamagishi,及J.Takeya:Inch-Size Solution-Processed Single-Crystalline Films of High-Mobility Organic Semiconductors,Applied Physics,Express 6(2013)076503報導一種藉由控制晶體生長方向製造顯著較大區域的單晶有機半導體的改良型邊緣鑄造溶液結晶技術。使用可移動的固體刀片邊緣使有機半導體液滴保持矩形,使得自基板之水平表面量測之液-氣邊界的液位輪廓線平行於刀片邊緣。藉由以與溶劑蒸發相同之速率補充有機半導體溶液來使得矩形液滴保持相同尺寸。因此,大區域晶體膜持續生長至若干吋之尺寸。獲得大於3×2cm2之尺寸的方形晶體且
製備TFT陣列以檢驗OFET效能。使用X射線繞射(XRD)量測值確定單晶薄膜之結晶度。
本發明之一個目標為提供基於可溶小分子半導體之大區域結晶半導體薄膜。
其中:R1及R2在每次出現時係獨立地選自C1-30烷基、C2-30烯基、C2-30炔基及C1-30鹵烷基,R3、R4、R5及R6獨立地為H或拉電子基團,其中R3、R4、R5及R6中之至少一者為拉電子基團;以及非導體聚合物。
本發明人已發現可藉由將非導體聚合物與有機半導體溶液混合來控制溶劑之乾燥速度,由此穩定薄膜之生長過程且改良薄膜之結晶度。在較佳實施例中,將聚(甲基丙烯酸甲酯)(PMMA)用作非導體聚合物。其他適合之非導體聚合物為例如聚苯乙烯及聚對苯二甲酸伸乙酯。

(甲基丙烯酸甲酯)。
式I及式II之半導體化合物以及非導體聚合物一般以各自0.1重量%至1.0重量%的濃度使用。溶液及半導體膜中半導體化合物對非導體聚合物的重量比一般為5:1至1:5,較佳為2:1至1:2,例如1:1。
較佳地使用以上所述之改良型邊緣鑄造方法生長半導體膜。經由使用可移動的溶液保持刀片來持續生長大面積單晶有機半導體薄膜。在刀片邊緣生長p型及n型低分子量有機半導體的高度均勻薄膜,尺寸高達10cm×10cm。XRD確認膜之結晶度極佳。基於大區域晶體膜之陣列式OFET顯現5-10cm2 V-1 s-1之極佳遷移率。晶體生長方法為容易的,且可用於在高速有機半導體TFT之低成本印刷製造中的高產量大面積印刷。
