下面对该阵列基板的制作方法的各个步骤进行详细的说明。
在步骤S201中,形成该栅电极20时,先采用物理气象沉淀法在玻璃基板10上沉积形成栅电极层,然后对该栅电极层进行图像化处理,从而形成该栅电极20。
在步骤S202中,该第一绝缘层30采用化学气象沉淀法沉积于该玻璃基板10以及该栅电极20上;其可以采用氮化硅、氧化硅等无机绝缘材料。
在步骤S203中,该半导体层40包括沉积于第一绝缘层30上的非晶硅层以及设置于该非晶硅层上的掺杂半导体层42。制作该半导体层40时,先采用气象沉淀法在第一绝缘层30上沉积一层非晶硅,然后对该一层非晶硅进行图像化处理形成位于底部的非晶硅层41以及位于非晶硅层41上的第一接触部以及第二接触部,并对该第一接触部以及第二接触部进行掺杂,以形成掺杂半导体层42。该掺杂半导体层40用于将源极70以及漏极60分别与非晶硅层41电连接。
在步骤S204中,该平坦层50可以采用氮化硅、氧化硅等无机绝缘材料,也可以采用有机绝缘材料。该平坦层50可以采用化学气象沉淀法沉积于该第一绝缘层30上。该平坦层50也可以采用纳米粉末状材料或液态绝缘材料采用3D打印形成。该平坦层50与该第一接触部以及第二接触部的远离该非晶硅层41的一端的端面齐平,便于后续的源极70以及漏极60的形成。
在步骤S205以及步骤S206中,该源极70设置于该第一接触部以及平坦层50上,该漏极设置于该第二接触部以及该平坦层50上。
在步骤S207中,该像素电极层80其上形成有多个像素电极。优选地,漏极60的远离源极70一侧的侧壁面朝向源极70的方向倾斜,该像素电极层80将该侧壁面覆盖并覆盖该漏极60的上端面的部分,漏极60的这种形状设置有利于提高该像素电极层80与该漏极60的接触面积,从而提高导电性。
在步骤S208中,该第二绝缘层90可以采用氮化硅和/或二氧化硅等材料进行化学气相沉淀形成。
本优选实施例提供的阵列基板的制作方法通过在第一绝缘层30上设置平坦层50,然后将源极以及漏极设置在该平坦层50以及半导体层40上,无需设置源极过孔以及漏极过孔即可实现源极、漏极与半导体层40的电连接,并且直接将像素电极层80设置于于平坦层50以及该漏极60上,无需设置过孔即可实现漏极60与像素电极层80的电连接,具有避免在开孔处形成气泡、提高开口率的有益效果,并且该平坦层50还增大了源极70、漏极60与栅电极20之间的距离,可以提高抗静电能力。
