本申请实施例提供一种阵列基板,下文进行详细说明。需说明的是,以下实施例的描述顺序不作为对实施例优选顺序的限定。
实施例一、
请参阅图1,本实施例提供了一种阵列基板100,阵列基板100包括基板12、薄膜晶体管11和遮光层13。
薄膜晶体管11设置在基板12上。薄膜晶体管11包括有源层113以及遮光层13,遮光层13设置在基板12上。遮光层13遮挡有源层113。遮光层13的材料包括硅半导体材料。
在传统的顶栅结构中,为保证薄膜晶体管光稳定性,需在有源层底部设置一遮光层。一般的采用不透明的金属作为遮光层,因金属具有较低电阻,需把缓冲层加厚才可充分绝缘。
在本实施例中,遮光层13采用硅半导体,硅半导体具有低透光率,可有效遮光,从而提高薄膜晶体管11的光稳定性。由于硅半导体具有较高电阻,缓冲层16即使降低厚度,例:4000埃降低至1000埃,也可保证良好的绝缘属性。且硅半导体层可通过等离子体增强化学气相沉积成膜,可采用有源层113的光罩进行图案化,节省一道光罩成本。
可选的,有源层113的材料包括氧化铟镓锌(IGZO)、铟镓锌钛氧化物(IGZTO)、铟锌氧化物(IZO)、铟镓锡氧化物(IGTO)等金属氧化物。
可选的,薄膜晶体管11还包括与有源层113异层设置的栅极111,栅极111设置在有源层113上。
可选的,遮光层13与有源层113异层设置,且有源层113设置在遮光层13的上方。
可选的,阵列基板100还包括缓冲层16和钝化层17。薄膜晶体管11还包括栅极绝缘层112、层间介电层116、源极114和漏极115。
可选的,缓冲层16设置在遮光层13上。有源层113设置在缓冲层16上。栅极绝缘层112设置在有源层113上。栅极111设置在栅极绝缘层112上。
可选的,层间介电层116覆盖有源层113、栅极绝缘层112和栅极111。层间介电层116设置有第一通孔151和第二通孔152。
可选的,源极114通过第一通孔151和有源层113的部分接触,漏极115通过第二通孔152与有源层113的部分接触。钝化层17设置在层间介电层116上。
在本实施例中,形成上述层间介电层116、缓冲层16、栅极绝缘层112和钝化层17的材料包括但不限于氧化硅(SiOx)、氮化硅(SiNx)、氮氧化硅(SiON)等介质材料,新型的有机绝缘材料如聚硅氧烷系材料,亚克力系材料,或聚酰亚胺系材料等,或高介电常数材料如氧化铝(AlOx),氧化铪(HfOx),氧化钽(TaOx)等。
在本实施例中,形成上述源极114、漏极115和栅极111材料可以是常用的金属材料,如Ag、Cu、Al、Mo等。也可以是多层金属,如MoNb/Cu/MoNb等。还可以是上述金属的合金材料,如AlNd、MoNb等。还可以是金属和透明导电氧化物(如ITO、AZO等),或其形成的堆栈结构如ITO/Ag/ITO等。
实施例二、
请参阅图2,本实施例提供了一种阵列基板100,阵列基板100包括基板12、薄膜晶体管11和遮光层13。
薄膜晶体管11设置在基板12上。薄膜晶体管11包括有源层113以及遮光层13,遮光层13设置在基板12上。遮光层13遮挡有源层113。遮光层13的材料包括硅半导体材料。
可选的,薄膜晶体管11还包括与有源层113异层设置的栅极111,有源层113设置在栅极111上。
可选的,遮光层13与有源层113异层设置,且有源层113形成在遮光层13的上方。
在传统的底栅结构中,通常采用氧化铟镓锌(IGZO)作为有源层。而随着产品规格的不断进阶,对有源层迁移率的要求越来越高,一般通过提高铟含量来提高有源层材料的迁移率,但会导致有源层带隙减小,薄膜晶体管光稳定性差,因此薄膜晶体管对遮光性有了更高的要求,转移电流特性曲线如图3所示,图3中左侧为未增加遮光层时的转移电流特性曲线,右侧为增加遮光层时的转移电流特性曲线。
在本实施例中,在有源层113的下方设置硅半导体层,从而提高薄膜晶体管11的光稳定性。且硅半导体层可采用有源层113的光罩进行图案化,无需新开黄光光罩。

在本实施例中,形成上述源极114、漏极115、栅极111和电极14材料可以是常用的金属材料,如Ag、Cu、Al、Mo等。也可以是多层金属,如MoNb/Cu/MoNb等。还可以是上述金属的合金材料,如AlNd、MoNb等。还可以是金属和透明导电氧化物(如ITO、AZO等),或其形成的堆栈结构如ITO/Ag/ITO等。
