Description

一种阵列基板及其制备方法、显示面板、显示装置
技术领域
本发明属于显示技术领域,具体涉及一种阵列基板及其制备方法、显示面板、显示装置。
背景技术
显示器件中的薄膜晶体管(Thin Film Transistor,TFT)主要有两大类:(1)位于显示(Active Area,AA)区,用于控制液晶偏转,一般称为像素区TFT;(2)位于AA区周边,用于驱动各条栅线,称为周边区TFT。
通常来讲,周边区TFT需要拥有以下特点:高切换速度,高驱动电流,低温多晶硅(Low Temperature Poly-silicon,LTPS)型的TFT更符合其要求;像素区TFT需要拥有以下特点:较低的漏电流,均一性好,氧化物(Oxide)型的TFT更符合其要求。
在普通的OLED/LCD显示器中,通常只采用单一类型的TFT,难以同时满足上述两种不同类型的TFT的特性需求。
发明人发现现有技术中至少存在如下问题:若阵列基板同时包含低温多晶硅型TFT和氧化物型TFT等两种TFT结构,则低温多晶硅型作为周边区TFT使用,氧化物型作为像素区TFT使用,且像素区TFT部分的氧化物型为底栅结构,如图1(图1中的其余结构未标示)所示。虽然该方案可以结合两种TFT的优势,提高OLED/LCD的显示性能,但是存在以下问题:(1)像素区10的TFT结构的第一有源层12采用氧化物(例如铟镓锌氧化物,indium galliumzinc oxide,IGZO)制成,在制作时需要经过退火工艺,而周边区20的TFT结构的第二有源层22由LTPS材料构成,此时已经完成掺杂,第一有源层的退火工艺的高温可能会对掺杂后的LTPS性能造成不利影响,从而降低第二有源层的掺杂效果;(2)像素区TFT采用的是背沟道刻蚀(BCE,Back Channel Etching)型结构,此时源漏极的刻蚀可能会对氧化物有源层的沟道结构产生一定程度的破坏。

S01a、在衬底10上沉积黑色有机物,或者高反低透金属或合金,如Al、Mo、Cu、Cu/Al合金等以形成厚度为20-200nm的遮光金属层,并进行图案化以形成第一遮光部31和第二遮光部32。
需要说明的是,在像素区11、周边区12对应有源层的位置处均需设置遮光部,这样设计的作用是:当该阵列基板用于显示装置时,各自的遮光部可以遮挡背光源的光,保护有源层,即第二遮光部32保护第二有源层22,第一遮光部31保护第一有源层21。
S01b、沉积一层厚度为20-200nm的SiNx,一层厚度为100-500nm的SiO2,以形成覆盖所述遮光层的第一缓冲层41。具体的,第一缓冲层41可以是多层结构,也可以是单层结构,多层或者单层结构的材料可以选自SiNx或SiO2
S02a、在第一缓冲层41上沉积厚度为20-200nm的IGZO作为第一半导体层,将第一半导体层图案化,以形成第一薄膜晶体管的第一有源层21。
S02b、形成第二有源层22。
如图3所示,可以在第一缓冲层41上形成第二半导体层,也可以如图4所示,先沉积一层厚度为50-200nm的SiO2,然后再沉积一层厚度为20-200nm的SiNx作为覆盖所述第一有源层21的第二缓冲层42,然后再在第二缓冲层42上与周边区12对应的位置形成第二半导体层;由于第一半导体层的IGZO为敏感材料,容易受到后续工艺的影响,因此较为优选的方式是图4的方式,即在此增加第二缓冲层42的作用是:第二缓冲层42可以充分保护第一半导体层的IGZO。
具体的,形成第二有源层22的步骤包括:先沉积20-200nm a-Si层作为第二半导体层,之后进行脱氢,此时借助脱氢的高温可以完成IGZO的退火过程。更具体的,对a-Si层进行激光晶化(ELA)形成P-Si层,之后对P-Si层进行图案化;对P-Si有源层进行沟道掺杂和离子注入。当然采用气相化学气相沉积或固相晶化等方式形成P-Si层也是可行的。
需要说明的是,所述第一半导体层先于所述第二半导体层形成,先形成第一半导体层的作用是:在对第二半导体层进行高温脱氢的同时完成所述第一半导体层的退火工艺。这样第一半导体层的退火过程不会对第二半导体层的性能造成不利影响,有利保证沟道掺杂效果。具体的,高温脱氢在350-650℃下进行,脱氢时间为20-60min,该工艺中要求H含量小于2%。
S03a、沉积一层厚度为50-200nm的SiO2,一层厚度为20-200nm的SiNx以形成覆盖所述第二有源层22的栅极绝缘层50。
S03b、在栅极绝缘层50上对应第一有源层、第二有源层的位置处形成厚度为50-500nm的第一栅极51、第二栅极52。
具体的,第一栅极51、第二栅极52的材料可以选自Mo或Mo/Nb合金或Mo/Al/Mo合金。
S03c、形成覆盖所述第一栅极51和第二栅极52的层间介质层60。
具体的,层间介质层60包括一层100-500nm厚的SiNx材料,和一层100-500nm厚的SiO2材料。
S04a、在所述层间介质层60上对应第一有源层21和第二有源层22的位置处形成第一源漏极61、第二源漏极62;以及将所述第一源漏极61通过贯穿层间介质层60、栅极绝缘层50、第二缓冲层42的第一过孔与第一有源层21连接;将所述第二源漏极62通过贯穿层间介质层60、栅极绝缘层50的第二过孔与第二有源层22连接。
具体的,形成第一源漏极61、第二源漏极62的材料选自Ti或Al;更具体的,其可以是三层结构,例如,一层厚度为30-300nm的Ti,加一层厚度为100-600nm的Al,加一层厚度为30-300nm的Ti。
S04b、在第一源漏极61、第二源漏极62上依次形成平坦化层71、公共电极72、钝化层73、像素电极74。
具体的,平坦化层71的厚度为500-5000nm,平坦化层71的材料可以选自丙烯酸类树脂;公共电极72的厚度为20-200nm,公共电极72的材料可以选自ITO等透明金属氧化物;钝化层73的厚度为100-400nm;钝化层73的材料可以是SiNx;像素电极74的厚度为20-200nm,公共电极72的材料可以选自ITO等透明金属氧化物。
