Description

主链中含有喹喔啉环的用于有机薄膜晶体管的有机半导体聚合物
发明背景
本非临时申请按照35 U.S.C.§119(a)要求于2003年12月8日提交的韩国专利申请No.2003-88655的优先权,其内容引入作为参考。
发明领域
本发明涉及聚合物主链中含有喹喔啉环的有机薄膜晶体管用有机半导体聚合物。更具体地,本发明涉及具有n型半导体特性(如高电子亲合性)的喹喔啉环被结合到具有p型半导体特性的聚噻吩上的有机薄膜晶体管用有机半导体聚合物,从而同时表现出p型和n型半导体特性。
相关技术描述
有机薄膜晶体管用有机半导体材料主要分为低分子量材料如并五苯和高分子量材料如聚噻吩。与低分子量材料相比,尽管高分子量材料具有差的器件特性如低电荷载流子迁移率(charge carrier mobility),但它们在易加工性方面存在优势:它们可通过溶液加工如印刷技术被低成本地大面积加工。由于高分子量有机半导体材料可被形成溶液,不象低分子量材料,因而可通过丝网印刷、喷墨和滚筒印刷技术将它们形成为薄膜。高分子量有机半导体材料的这种优势使在塑料薄膜上低成本地制造大面积晶体管成为可能。
剑桥大学和Seiko Epson Corp.已经制造并试验了使用聚噻吩基材料的基于高分子量的有机薄膜晶体管,即F8T2(WO 00/79617 A1,Science,2000,vol.290,第2132~2126页,电荷载流子迁移率:0.01~0.02cm2/Vs)。LucentTechnologies Inc.的Bao.Z等人公开了使用P3HT制造有机薄膜晶体管器件,P3HT为一种区域有序(regioregular)聚合物(U.S.专利No.6,107,117,电荷载流子迁移率:0.01~0.04cm2/Vs)。如上所述,与使用并五苯的有机薄膜晶体管相比,这些使用高分子量材料的有机薄膜晶体管具有低的电荷载流子迁移率,但不需要高的操作频率,并能低成本制造。
对于有机薄膜晶体管的商业化,应满足重要参数高I/I比和高电荷载流子迁移率。为满足这些参数,需要将关态漏电流(off-state leakage current)降低到尽可能低的程度。代表性的区域有序聚噻吩基聚合物P3HT显示出约0.01cm2/Vs的电荷载流子迁移率,但由于其高关态漏电流(10-9A或更高)而具有400或更小的低I/I比(U.S.专利6,452,207和6,107,117)。最近,已以不同的方式尝试提高这些性能。
来自Lucent Technologies Inc.的研究团队报道了通过使用n型无机半导体材料和p型有机半导体材料的组合作为活性层提高有机薄膜晶体管器件的物理性能(U.S.专利5625199)。但是,根据该专利,与需要沉积的常规硅基薄膜晶体管工艺没有特殊差别,其不适用于薄膜晶体管器件的大规模生产。
T.Yamamoto等人提出了具有不同电性能的杂芳环如喹喔啉环被引入到聚合物主链中的有机半导体聚合物,从而同时表现出p型和n型半导体特性(J.Am.Chem.Soc.1996,118,10389)。直到现在,由于在有机溶剂中的低溶解性和差的成膜性,因此还没有报道聚合物作为有机薄膜晶体管活性层的应用。
直到现在,还没有报道能同时满足高电荷载流子迁移率和低关态漏电流要求的基于高分子量的有机薄膜晶体管。

实施例1:有机薄膜晶体管器件的制造
在这个实施例中,分别使用制备实施例5中和对比制备实施例中的有机半导体材料制造有机薄膜晶体管。按照下面的步骤制备每个有机薄膜晶体管。
首先,利用CVD技术在洗过的硅衬底上沉积氧化硅薄膜至3000

的厚度。利用真空沉积技术在氧化硅薄膜上沉积Al形成厚度为2000

的栅电极。将10wt%的聚乙烯基苯酚基化合物在NMP中的溶液以1000rpm旋涂到栅电极上至厚度为7000
Figure C20041009836500153
并在氮气氛和100℃下焙烧1小时形成有机栅绝缘薄膜。然后,将有机半导体材料在甲苯中的1wt%的溶液旋涂至厚度为1000
Figure C20041009836500154
并在氮气氛和100℃下焙烧1小时形成活性层。通过沟道(channel)长度为100μm和沟道宽度为2mm的遮蔽掩膜(shadow mask)将作为源-漏电极材料的Au(金)沉积到有机活性层上至厚度为1000
Figure C20041009836500155
以制造如图4所示的顶部接触(top-contact)有机薄膜晶体管(1:衬底,2:栅电极,3:栅绝缘层,4:源极,5:漏极,6:有机活性层)。
使用KEITHLEY半导体特性系统(4200-SCS)绘制显示器件电流转移特性的曲线(图5a和5b)。使用下面的饱和区电流方程由曲线计算器件的电荷载流子迁移率:
I SD = WC 0 2 L μ ( V G - V T ) 2
可根据下面的方程由(ISD)1/2-VG图的斜率得到器件的电荷载流子迁移率:
I SD = μ C 0 W 2 L ( V G - V T )
slope = μ C 0 W 2 L
μ FET = ( slope ) 2 2 L C 0 W
其中ISD:源-漏电流;μ或μFET:电荷载流子迁移率;Co:绝缘层电容;W:沟道宽度;L:沟道长度;VG:栅压;和VT:阈电压。
通过测量关态时流过的电流得到关态漏电流(I)。
由开态最大电流值与关态最小电流值的比得到I/I比。
表1
  有机活性层   电荷载流子迁移率(cm<sup>2</sup>/Vs)   I<sub>开</sub>/I<sub>关</sub>比   关态漏电流(A)
  制备实施例5(PTQx-T)   0.0012   1000   4.0×10<sup>-11</sup>
  对比制备实施例(PTQx)   0.0004   500   1.2×10<sup>-11</sup>
从表1中可看出,由于聚噻吩基喹喔啉衍生物(PTQx)(对比制备实施例)包含具有高电子亲合性的喹喔啉环,因而有机薄膜晶体管的关态漏电流相当大地降低到10-11A,但在电荷载流子迁移率和I/I比上只有很小的改进。相反,本发明的聚噻吩基喹喔啉衍生物(制备实施例5,PTQx-T)显示出比PTQz提高一个数量级的迁移率和I/I比,同时保持了关态漏电流。
尽管为了说明目的已公开了本发明的优选实施方案,但本领域那些技术人员能认识到各种改变、添加或替换都是可能的,只要不脱离附属权利要求中公开的本发明的范围和精神。
