现有技术中,低温多晶硅(Low Temperature Poly-silicon,LTPS)量测线宽机针对产品进行量测后均需要针对产品进行切片,其中,量测一般用到光学显微镜(Optical Microscope,OM)以及扫描电子显微镜(scanning electron microscope,SEM),但是量测手段都是在生产出实际产品后去量测的,如果存在问题还需再次加工,加工产品阶段无法实现量测线宽。
并且,为了提升器件的性能,常在产品加工完成后通过低温多晶硅(Low Temperature Poly-silicon,LTPS)量测线宽机针对产品进行量测。但如果量测出加工完成后的产品线宽存在问题,会重新送回加工,增大了实际产品送样分析对比的时间,降低了生产效率。本申请提供一种掩膜版的量测补值方法,在预留区设置长度尺,以使在产品加工时可以通过该长度尺进行测量。从而比对出实际产品线宽值与理想产品线宽值的差值,在产品加工阶段进行相应的补值处理从而保证量测准确性,提高生产效率以及减少实际产品送样分析对比。

110、提供一掩膜版100,所述掩膜版100包括显示区101以及预留区102,所述预留区102设置有长度尺1021,所述掩膜版100的显示区101上设置有多个第一图形1011,根据预设距离值S确定所述掩膜版100上所述多个第一图形1011的位置。
其中,掩膜版100包括有显示区101以及预留区102,显示区101用于设置图案化处理时设置在掩膜版100上的多个第一图形1011,其中,该多个第一图形为后续图案化处理时以掩膜版100为载体的原始图形。预留区102上的长度尺1021由刻画的多条刻度线10211形成的一个量测线宽的量测工具,相邻两刻度线10211之间的距离可以设置为与芯片线宽对应的计量单位,例如:设定相邻两刻度线10211之间的距离为0.1μm或者0.2μm等,这里不作限定,根据具体芯片线宽而定,长度尺1021的作用在于后续光学量测仪测量图案化处理后在玻璃基板上形成第二图形2011时,能直观清楚的将产品线宽值表示出来。该多个第一图形1011的位置按照预先设定的距离值S与长度尺1021的刻度线10211进行比对设定。例如,按照每相邻的第一图形末端间的距离值为S来设定所述掩膜版100上所述多个第一图形1011的位置。
120、对所述多个第一图形1011进行图案化处理,在玻璃基板200上得到与所述多个第一图形1011对应的多个第二图形2011,并获取所述多个第二图形2011中相邻第二图形间2011的实际距离值(S1或S2)。
其中,为了将该掩膜版100上的多个第一图形1011转移到玻璃基板200上时,需要对掩膜版100进行图案化处理,以使在该玻璃基板200上形成与第一图形1011对应的多个第二图形2011,并通过长度尺1021量测该多个第二图形中相邻第二图形间的实际距离值(S1或S2)。
130、根据所述预设距离值S与所述第二图形间2011的实际距离值(S1或S2)得到补偿值△S。
补偿值△S可以是预设距离值S减实际距离值(S1或S2)得到的补偿值△S,其中,该补偿值△S可以为正,或者为负,补偿值△S的正负与图案化处理的方式有关,图案化处理时,玻璃基板上200的第二图形2011会随之增大或减小,如图2所示,第二图形2011随之增大,相邻第二图形2011的实际间距增大,变为S1,大于预设距离值,则补偿值△S=S-S1为负。反之则如图3所示,第二图形2011随之减小,相邻第二图形2011的实际间距减小,变为S2,小于预设距离值,则第一补偿值△S=S-S2为正。其中,补偿值△S还可以为实际距离值(S1或S2)减预设距离值S得到的补偿值△S,即△S=S1-S或△S=S2-S。
140、根据所述补偿值△S对所述第二图形2011进行补值处理。
其中,若补偿值△S是预设距离值S减实际距离值(S1或S2)得到的补偿值△S,且补偿值△S为正,则可以根据补偿值△S相应的对掩膜版100进行加窗处理;若补偿值△S是实际距离值(S1或S2)减预设距离S值得到的补偿值△S,且补偿值△S为负,也可以根据补偿值△S相应的对掩膜版100进行加窗处理,当下进行补值处理。
本申请提供一种掩膜版的量测补值方法,在预留区设置长度尺,以使在产品加工时可以通过该长度尺进行测量,从而比对出实际产品线宽值与理想产品线宽值的差值,在产品加工阶段进行相应的补值处理从而保证量测准确性,提高生产效率以及减少实际产品送样分析对比。

210、提供一掩膜版100,所述掩膜版包括显示区101以及预留区102,所述预留区102设置有长度尺1021,所述掩膜版100的显示区101上设置有多个第一图形1011,根据所述长度尺1021的刻度线10211与所述预设距离值确定所述掩膜版100上所述多个第一图形1011中相邻第一图形1011间的距离值为预设距离值S。
在一些实施例中,所述预设距离值S为所述多个第一图形1011中相邻第一图形1011末端间(A’-B’,B’-C’)的距离,和/或所述多个第一图形中相邻第一图形首端间(A-B,B-C)的距离。
其中,掩膜版100包括有显示区101以及预留区102,显示区101用于设置图案化处理时设置在掩膜版100上的多个第一图形1011,其中,该多个第一图形为后续图案化处理时以掩膜版100为载体的原始图形。预留区102上的长度尺1021由刻画的多条刻度线10211形成的一个量测线宽的量测工具,相邻两刻度线10211之间的距离可以设置为与芯片线宽对应的计量单位,例如:设定相邻两刻度线10211之间的距离为0.1μm或者0.2μm等,这里不作限定,根据具体芯片线宽而定,长度尺1021的作用在于后续光学量测仪测量图案化处理后在玻璃基板上形成第二图形2011时,能直观清楚的将第二图形2011线宽值表示出来。该多个第一图形1011的位置按照预先设定的距离值S与长度尺1021的刻度线10211进行比对设定,其中,S可以为如图1所示的相邻第一图形首端(A,B,C)的距离,如:A-B的距离为S,也可以为相邻第一图形末端(A’,B’,C’)的距离,如:A’-B’的距离为S,这里不作限定。
220、对所述多个第一图形1011进行曝光和/或蚀刻,使得所述玻璃基板200上的所述多个第二图形2011在水平方向上的长度减小或增大,以得到与所述多个第一图形1011对应的多个第二图形2011。
其中,为了将该掩膜版100上的多个第一图形1011转移到玻璃基板200上时,需要对掩膜版100进行曝光和/或蚀刻,因为整体图形会同步增大或缩小,因此,每两个第一图形1011的间距会同步改变,变为实际距离值(S1或S2)以使在该玻璃基板200上形成与第一图形1011对应的多个第二图形2011,并且,在曝光和/或蚀刻第一图形1011得到第二图形2011时,整体图形之间的间距不会因受到尺寸蚀刻(CD bias)影响。
230、根据所述长度尺1021的刻度线10211确定所述多个第二图形2011中相邻第二图形2011间的实际距离值(S1或S2)。
在一些实施例中,所述实际距离值(S1或S2)为所述多个第二图形2011中相邻第二图形2011末端间(A1’-B1’,B1’-C1’ ,A2’-B2’,B2’-C2’)的距离,和/或所述多个第二图形2011中相邻第二图形2011首端间(A1-B1,B1-C1 ,A2-B2,B2-C2)的距离。
通过长度尺1021量测该多个第二图形10211中相邻第二图形10211间的实际距离值(S1或S2),其中S1可以是相邻第二图形首端(A1-B1,B1-C1, A2-B2,B2-C2)的实际距离值,或者为相邻第二图形末端的实际距离值,如:(A1’-B1’,B1’-C1’, A2’-B2’,B2’-C2’),实际距离S2同上,这里不作赘述。
在一些实施例中,所述长度尺1021用于确定所述多个第一图形1011位置以及测量所述相邻第二图形2011间的实际距离值(S1或S2)。
通过刻度线10211来测量设置第一图形1011时的位置以及测量相邻第二图形2011间的实际距离值(S1或S2)
240、根据所述预设距离值S与所述实际距离值(S1或S2)的差值,得到所述补偿值△S。
其中,补偿值△S可以是预设距离值S减实际距离值(S1或S2)得到的补偿值△S,其中,该补偿值△S可以为正,或者为负,补偿值△S的正负与图案化处理的方式有关,图案化处理时,玻璃基板上200的第二图形2011会随之增大或减小,如图2所示,第二图形2011随之增大,相邻第二图形2011的实际间距增大,变为S1,大于预设距离值,则补偿值△S=S-S1为负。反之则如图3所示,第二图形2011随之减小,相邻第二图形2011的实际间,减小,变为S2,小于预设距离值,则第一补偿值△S=S-S2为正。其中,补偿值△S还可以为实际距离值(S1或S2)减预设距离值S得到的补偿值△S,即△S=S1-S或△S=S2-S。
250、根据所述补偿值△S对所述第二图形2011进行补值处理。
其中,若补偿值△S是预设距离值S减实际距离值(S1或S2)得到的补偿值△S,且补偿值△S为正,则可以根据补偿值△S相应的对掩膜版100进行加窗处理;若补偿值△S是实际距离值(S1或S2)减预设距离S值得到的补偿值△S,且补偿值△S为负,也可以根据补偿值△S相应的对掩膜版100进行加窗处理,当下进行补值处理。
