具体实施方式
为了便于理解本发明,下面将参照相关附图对本发明进行更全面的描述。附图中给出了本发明的较佳实施例。但是,本发明可以以许多不同的形式来实现,并不限于本文所描述的实施例。相反地,提供这些实施例的目的是使对本发明的公开内容的理解更加透彻全面。
请参见图1和图2,本申请实施例提供一种驱动基板的制备方法。所述驱动基板10包括基底400,以及在所述基底400表面间相邻设置的异形显示驱动区100和正常显示驱动区200。所述异形显示驱动区100包括多个间隔设置的第一驱动电路单元110。所述第一驱动电路单 元110包括第一储存电容111。所述第一储存电容111包括第一介质层112。所述正常显示驱动区200包括多个间隔设置的第二电路驱动单元210。所述第二电路驱动单元210包括第二储存电容211。所述第二储存电容211包括第二介质层212。所述第一介质层112和所述第二介质层212形成于同一层面。
在所述异形显示驱动区100中,可以设置有多个第一信号线(未图示)。每个所述第一信号线可以电连接多个所述第一驱动电路单元110。在所述正常显示驱动区200中,可以设置有多个第二信号线(未图示)。每个所述第二信号线可以连接多个所述第二电路驱动单元210。所述正常显示驱动区200的形状是规则的,而所述异形显示驱动区100中存在开槽等结构,因此每个所述第一信号线连接的所述第一驱动电路单元110的数量可能会少于所述第二信号线连接的所述第二电路驱动单元210的数量,导致每个所述第一信号线的电容负载与每个所述第二信号线的电容负载可能并不相同。由于所述第一信号线用于驱动显示屏异形显示区100的像素的显示,而所述第二信号线用于驱动显示屏正常显示区200的像素的显示,因此所述显示屏异形显示区100的显示亮度与所述显示屏正常显示区200的显示的亮度存在着差异。
所述驱动基板10的制备方法包括:
S10,基于所述异形显示驱动区100的第一信号线的电容负载和所述正常显示驱动区200的第二信号线的电容负载的差值,得到所述第一介质层112的第一厚度值;
S20,提供基底400,并在所述基底400表面沉积第一金属层113;以及
S30,通过膜厚控制模型,控制成膜工艺参数,在所述第一金属层113表面沉积所述第一介质层112和所述第二介质层212,以使所述第一介质层112的厚度达到所述第一厚度值,以使所述第二介质层212的厚度达到第二厚度值,所述第一厚度值小于所述第二厚度值。
在步骤S10中,所述第一信号线的电容负载可以为所述第一信号线连接的所有的第一驱动电路单元110中的所有的第一储存电容111的电容负载总和。所述第二信号线的电容负载可以为所述第二电路驱动单元210中的所有第二储存电容211的电容负载的总和。通过增加每个所述第一储存电容111的电容负载,可以增加所述第一信号线的电容负载。基于所述第一信号线的电容负载和所述第二信号线的电容负载可以计算每个所述第一驱动电路单元110需要增加的补偿电容值。
电容计算公式为C=εS/4πkd。其中,ε是一个常数,S为电容极板的正对面积,d为电容极板的距离,k则是静电力常量。可知,通过减少所述第一储存电容111的第一介质层112厚度,可以增加所述第一储存电容111的电容负载。基于该补偿电容值,通过所述电容计算公式可以得到所述第一厚度值。
在步骤S20中,所述第一金属层113可以为透明金属氧化物半导体材料。所述透明金属 氧化物半导体材料可以为铟镓锌氧化物等。利用光刻制程对所述第一金属层113进行图形化处理后,可以得到所述第一储存电容111和所述第二储存电容211的电容电极。
在步骤S30中,所述膜厚控制模型可以包括介质气体流速与膜厚生长速度关系模型、温度与膜厚生长速度关系模型、压强与膜厚生长速度关系模型等。所述膜厚控制模型可以根据经验值获得,也可以通过模拟计算获得。在一个实施例中,所述膜厚控制模型可以适用于CVD设备。所述成膜工艺参数可以包括压强、温度、介质气体流速等。通过所述膜厚控制模型可以控制CVD设备中的压强、介质气体流速、温度等工艺条件,进而控制所述第二介质层212的厚度达到第二厚度值,所述第一厚度值小于所述第二厚度值。
在本领域中,所述第一储存电容111的电容负载值与所述第二储存电容211的电容负载值一般是相同的。即所述第一介质层112和所述第二介质层212的厚度相同,可以均为H 1。在一个实施例中,所述第一信号线的电容负载值为N,所述第一信号线连接的所述第一储存电容111的数量为X。所述第二信号线的电容负载值为M,M大于N;所述第二信号线连接的所述第二储存电容211的数量为Y,Y大于X。因此每个所述第一驱动电路单元110中的所述第一储存电容111需要增加的补偿电容值为Q=(M-N)/X。由Q=εS/4πkd可以算出每个所述第一介质层112需要减少的厚度d。因此可以得到需要的所述第一厚度值H 2=H 1-d。
本申请提供的驱动基板10的制备方法,包括S10,基于所述异形显示驱动区100的电容负载和所述正常显示驱动区200的电容负载的差值,得到所述第一介质层112的第一厚度值;S20,提供基底400,并在所述基底400表面沉积第一金属层113;S30,通过膜厚控制模型,控制工艺参数,在所述第一金属层113表面沉积所述第一介质层112和所述第二介质层212,以使所述第一介质层112的厚度达到所述第一厚度值,以使所述第二介质层212的厚度达到第二厚度值。通过使所述第一介质层112的厚度小于所述第二介质层212的厚度,可以增加所述第一储存电容的电容负载,进而增加所述第一信号线的电容负载,以使得所述第一信号线的电容负载和所述第二信号线的电容负载趋于相同。因而,使得所述显示屏异形显示区的显示亮度与所述显示屏正常显示区的显示的亮度趋于相同。
在一个实施例中,所述膜厚控制模型包括介质气体流速与膜厚生长速度关系模型。所述介质气体流速与膜厚生长速度关系模型包括介质气体流速与膜厚生长速度关系式,步骤S30包括:
S31,在所述第一金属层113表面同时沉积所述第一介质层112和所述第二介质层212;
S32,控制介质气体依次通过所述第二介质层212和所述第一介质层112,所述介质气体经过所述第一介质层112时为第一气流速度值,所述介质气体经过所述第二介质层212时为第二气流速度值;以及
S33,基于所述第一厚度值和所述第一气流速度值,通过所述介质气体流速与膜厚生长速度关系式,得到所述第一介质层112的第一生长时间,以使所述第一介质层112生长到所述第一厚度值;基于所述第二厚度值和所述第二气流速度值,通过所述介质气体流速与膜厚生长速度关系式,得到所述第二介质层212的第二生长时间,以使所述第二介质层212生长到所述第二厚度值。
在步骤S31中,在一个实施例中,可以通过化学气相沉积方法,在所述第一金属层113表面同时沉积所述第一介质层112和所述第二介质层212。即所述第一介质层112和所述第二介质层212可以在同一个工序中制作。
在步骤S32中,在一个实施例中,可以使得所述第一金属层113设置于一水平面。如图3所示,控制所述介质气体流速为单一工艺变数,反应室600内的温度、压强等工艺条件是均匀的。使得所述介质气体依次通过所述第二介质层212的沉积位置和所述第一介质层112的沉积位置。由于重力以及气流扩散作用,所述第二介质层212的沉积位置的沉积速度大于所述第一介质层112的沉积位置的沉积速度。因此所述第二介质层212的膜厚生长速度大于所述第一介质层112的膜厚生长速度。所述介质气体流速与膜厚生长速度关系模型反应了介质气体流速与膜厚生长速度的对应关系。
在一个实施例中,反应室600的体积可以为25L,所述介质气体可以为三甲硅烷基胺气体和氨气,所述三甲硅烷基胺气体和氨气的流量比可以为5:1,所述三甲硅烷基胺气体和氨气混合气体可以以0.2L/min的速度通入所述反应室600。通过流量计测量,所述混合气体在所述第二介质层212的沉积位置的所述第一气流速度值为0.15L/min,在所述第一介质层112的沉积位置的所述第二气流速度值为0.8L/min。
在步骤S33中,在一个实施例中,通过所述第一气流速度值0.15L/min和所述第二气流速度值0.8L/min,基于所述介质气体流速与膜厚生长速度关系式,可以得到所述第二介质层212的膜厚生长速度为0.5nm/s,所述第一介质层112的膜厚生长速度为0.3nm/s。在一个实施例中,所述第二厚度值为110nm,所述第一厚度值为60nm。因此可以通过所述第一介质层112的膜厚生长速度0.3nm/s和所述第一厚度值60nm可以得到所述第一生长时间为200s。通过所述第二厚度值110nm和所述第二介质层212的膜厚生长速度0.5nm/s,可以得到所述第二生长时间为220s。可以理解,介质气体流速与膜厚生长速度关系式可以通过实验获得。即可以先获得多个介质气体流速与膜厚生长速度一一对应的数据,再对所述数据进行非线性拟合,得到所述介质气体流速与膜厚生长速度关系式。
在上述实施例中,可以通过控制介质气体的流向等工艺参数,使得所述第一介质层112的生长时间为200s,所述第二介质层212的生长时间为220s。
参见图3,在一个实施例中,所述第二生长时间大于所述第一生长时间。当到达所述第一生长时间时,在所述第一介质层112和所述第二介质层212之间设置阻隔板610以阻止所述第一介质层112生长。由上述实施例可知,由于介质气体的流向为依次经过所述第二介质层212的沉积位置和所述第一介质层112的沉积位置,而所述第二生长时间大于所述第一生长时间,因此所述第一介质层112的厚度首先达到所述第一厚度值。当所述第一介质层112的厚度达到所述第一厚度值后,在所述第一介质层112和所述第二介质层212之间设置阻隔板610,使得所述介质气体无法再到达所述第一介质层112。所述第一介质层112就无法继续生长,而所述第二介质层212可以继续生长。因而所述第二介质层212的厚度可以大于所述第一介质层112的厚度。从而可以增加所述第一扫描线的电容负载,使得所述第一扫描线的电容负载和所述第二扫描线的电容负载趋于相同。可以理解,所述阻隔板610可以设置在所述反应室600的中间。所述阻隔板610的动作可以通过自动化控制。只需在现有反应室600内设置有关阻隔板610,即可利用上述实施例的生长材料的方式在一道工序中同时生长出厚度不同的所述第一介质层112和所述第二介质层212,具有方便高效,节省成本的优点。
在一个实施例中,所述介质气体包括三甲硅烷基胺气体和氨气。所述介质气体还可以为氮气、水蒸气以及含有硅元素化合物的混合气体。
在一个实施例中,所述膜厚控制模型包括温度与膜厚生长速度关系模型,所述温度与膜厚生长速度关系模型包括温度与膜厚生长速度关系式,所述膜厚控制模型步骤S30包括:
S310,在所述第一金属层113表面同时沉积所述第一介质层112和所述第二介质层212;
S320,设定所述第一介质层112和所述第二介质层212具有相同的第三生长时间,基于所述第三生长时间和所述第一厚度值和所述第二厚度值,得到所述第一介质层112的第一生长速度值和所述第二介质层212的第二生长速度值;以及
S330,基于所述第一生长速度值和所述第二生长速度值,通过所述温度与膜厚生长速度关系式,确定所述第一介质层112的第一生长温度,以使得所述第一介质层112生长到所述第一厚度值;确定所述第二介质层212的第二生长温度,以使所述第二介质层212生长到所述第二厚度值。
在步骤S320中,所述第三生长时间可以为250s,所述第一厚度值为80nm,所述第二厚度值可以为110nm。因此所述第一生长速度值为0.32nm/s,所述第二生长速度值为0.44nm/s。
在步骤S330中,在以温度作为单一变数的前提下,所述温度与膜厚生长速度关系模型中包括了生长速度值与温度值的对应关系,可以理解,所述温度与膜厚生长速度关系式可以通过实验获得。即可以先获得多个温度值与生长速度值一一对应的数据,再对所述数据进行非线性拟合,得到所述温度与膜厚生长速度关系式。在一个实施例中,可以确定到达所述第一 生长速度值0.32nm/s的温度为545℃,到达所述第二生长速度值0.44nm/s的温度为720℃。在一个实施例中,可以分别在所述第一介质层112和所述第二介质层212的下方设置加热炉,通过设定所述加热炉的温度来控制所述第一介质层112和所述第二介质层212的生长温度。
在一个实施例中,所述第一生长温度为500℃-600℃,所述第二生长温度为700℃-750℃。在所述第一生长温度为500℃-600℃、所述第二生长温度为700℃-750℃时,所述第一介质层112和所述第二介质层212的厚度生长均匀,水准厚度的差距不超过0.1nm。优选地,所述第一生长温度为545℃。所述第二生长温度为720℃。在该温度条件下,所述第一介质层112和所述第二介质层212生长的厚度控制效果最好,并且水平度最高。
在一个实施例中,步骤30之前,还包括清理所述第一金属层113表面的步骤。在一个实施例中,主要清理的物质为在形成所述第一金属层113时留在所述第一金属层113表面的光阻液。
在一个实施例中,在所述步骤S30之后,还包括:
S41,对所述第一介质层112和所述第二介质层212进行图形化处理;以及
S42,在所述第一介质层112和所述第二介质层212的表面上形成第二金属层114。
在一个实施例中,可以通过光刻对所述第一介质层112和所述第二介质层212进行图形化处理。
在一个实施例中,所述第二金属层114可以为钼、钛或者钼钛合金等,其可以通过物理沉积获得。
在一个实施例中,所述第一介质层112和所述第二介质层212的材料为氧化硅或氮化硅。氧化硅或氮化硅材料具有良好的绝缘特性和较高的介电常数。
在一个实施例中,所述第一厚度值为50nm-130nm,所述第二厚度值为140nm-200nm。通常而言,当所述第一厚度值为50nm-130nm,所述第二厚度值为140nm-200nm时,所述驱动基板10的异形显示驱动区100的所有第一储存电容111的电容负载和所述正常显示驱动区200的所有第二储存电容211的电容负载趋于相同。在该范围内,所述第一厚度值和所述第二厚度值可以根据所述驱动基板10的电路的具体走线和开槽的形状和大小计算得到。
以上所述实施例的各技术特征可以进行任意的组合,为使描述简洁,未对上述实施例中的各个技术特征所有可能的组合都进行描述,然而,只要这些技术特征的组合不存在矛盾,都应当认为是本说明书记载的范围。
以上所述实施例仅表达了本申请的几种实施方式,其描述较为具体和详细,但并不能因此而理解为对本申请范围的限制。应当指出的是,对于本领域的普通技术人员来说,在不脱离本申请构思的前提下,还可以做出若干变形和改进,这些都属于本申请的保护范围。因此, 本申请专利的保护范围应以所附权利要求为准。
