具体实施方式
体现本公开特征与优点的典型实施例将在以下的说明中详细叙述。应理解的是本公开能够在不同的实施例上具有各种的变化,其皆不脱离本公开的范围,且其中的说明及附图在本质上是作说明之用,而非用以限制本公开。
在对本公开的不同示例性实施方式的下面描述中,参照附图进行,附图形成本公开的一部分,并且其中以示例方式显示了可实现本公开的多个方面的不同示例性结构,系统和步骤。应理解的是,可以使用部件,结构,示例性装置,系统和步骤的其他特定方案,并且可在不偏离本公开范围的情况下进行结构和功能性修改。而且,虽然本说明书中可使用术语“之上”,“之间”,“之内”等来描述本公开的不同示例性特征和元件,但是这些术语用于本文中仅出于方便,例如根据附图中的示例的方向。本说明书中的任何内容都不应理解为需要结构的特定三维方向才落入本公开的范围内。
本公开的一个实施例提供了一种半导体标记制作方法,请参考图1,半导体标记制作方法包括:
S101,提供周向边缘经OPC修正后的图形10;
S103,在图形10上裁剪出多个独立的对准段;
S105,拼接多个对准段,以形成周向边缘经OPC修正的半导体标记。
本公开一个实施例的半导体标记制作方法通过对周向边缘经OPC修正后的图形10进 行裁剪后拼接,以此获得周向边缘经OPC修正的半导体标记,即可以在多个对准段拼接后即可形成周向边缘经OPC修正的半导体标记,省去了形成半导体标记后再进行OPC修正的时间,以此提高半导体标记的制作效率。
需要说明的是,光学邻近修正(Optical Proximity Correction,OPC)技术就是通过对图形做系统的改变,补偿图形的扭曲和偏移,使在晶片衬底上最终形成的曝光图形达到电路图形的设计要求。而本实施例中,通过选用经OPC修正后的图形10再对其进行裁剪,即裁剪出的至少部分的对准段经OPC修正,因此将多个对准段拼接后可以形成周向边缘经OPC修正的半导体标记。
在一个实施例中,对准段包括经OPC修正的原始边缘11和未经OPC修正的裁剪边缘12;其中,多个对准段的相应的裁剪边缘12相拼接以形成半导体标记。即待拼接的对准段按照相应的裁剪边缘12进行拼接,而经OPC修正的原始边缘11围成了半导体标记的周向边缘,因此最终形成的半导体标记是周向边缘经OPC修正的半导体标记。
在一个实施例中,多个对准段包括:第一对准段13,第一对准段13包括一个裁剪边缘12;第二对准段14,第二对准段14包括一个裁剪边缘12,第一对准段13与第二对准段14相对接以形成第一半导体标记20;其中,第一对准段13和第二对准段14通过裁剪图形10相对的两侧获得,即获得的第一对准段13和第二对准段14的相应的两个拐角处均是经OPC修正过的。
可选地,第一对准段13和第二对准段14可以通过裁剪图形10相对的两个对角形成。即裁剪图形10相对的两侧包括裁剪图形10的上下两侧,左右两侧,或者是相对的两个拐角。
在一些实施例中,如图2所示,半导体标记制作方法包括:
如图2(a)所示,提供一周向边缘经OPC修正后的图形10;
如图2(b)所示,剪切图形10上下两侧,以得到第一对准段13与第二对准段14;
如图2(c)所示,将第一对准段13的裁剪边缘12与第二对准段14的裁剪边缘12相对接形成第一半导体标记20。
在一些实施例中,如图5所示,半导体标记制作方法包括:
如图5(a)所示,提供一周向边缘经OPC修正后的图形10;
如图5(b)所示,剪切图形10左右两侧,以得到第一对准段13与第二对准段14;
如图5(c)所示,将第一对准段13的裁剪边缘12与第二对准段14的裁剪边缘12相对接形成第一半导体标记20。
在一些实施例中,在得到图2(b)或者如图5(b)所示的第一对准段13与第二对准段14后,可以将第一对准段13与第二对准段14的中间段切除后进行拼接,即将第一对准段13与第二对准段14剪短,以此拼接出来的半导体标记要比第一半导体标记20短。
在一个实施例中,形成第一半导体标记20后,半导体标记制作方法还包括:将第一半导体标记20依次裁剪为第一段21、第二段22以及第三段23;对接第一段21和第三段23,以形成第二半导体标记30。即通过将第一半导体标记20的中间部分去除,可以得到一个比第一半导体标记20短的第二半导体标记30。
在一些实施例中,如图3所示,半导体标记制作方法包括:
如图3(a)所示,形成一周向边缘经OPC修正后的第一半导体标记20;

如图3(c)所示,将第一段21的裁剪边缘12和第三段23的裁剪边缘12相对接形成第二半导体标记30,即去除了第二段22。

如图6(c)所示,将第一段21的裁剪边缘12和第三段23的裁剪边缘12相对接形成第二半导体标记30,即去除了第二段22。
需要说明的是,图3中的第一半导体标记20由图2的半导体标记制作方法获得,而图6中的第一半导体标记20由图5的半导体标记制作方法获得。
在一个实施例中,形成第一半导体标记20后,半导体标记制作方法还包括:将第一半导体标记20裁剪为第一段24和第二段25;将第一段24和第二段25相对且间隔设置,以形成第一填充区域1;在第一填充区域1内填充第一补偿图形段,以形成第三半导体标记40;其中,第一补偿图形段在填充之前经OPC修正,或第一补偿图形段在填充之后经OPC修正。即通过将第一半导体标记20由中间剪开,以此进行加长处理,从而得到一个比第一半导体标记20长的第三半导体标记40。
需要说明的是,第一补偿图形段是补充在第一段24和第二段25之间,因此在对其进行OPC修正时只是进行直边的修正,而不用进行拐角处修正,整个修正难度较低,因此修正的效率会相对较高。
在一些实施例中,如图4所示,半导体标记制作方法包括:
如图4(a)所示,形成一周向边缘经OPC修正后的第一半导体标记20;
如图4(b)所示,将第一半导体标记20剪切为两段,以得到第一段24和第二段25,且将第一段24的裁剪边缘12与第二段25的裁剪边缘12拉开后在二者之间形成了第一填充区域1;
如图4(c)所示,向第一填充区域1填充第一补偿图形段后得到了第三半导体标记40。

如图7(a)所示,形成一周向边缘经OPC修正后的第一半导体标记20;
如图7(b)所示,将第一半导体标记20剪切为两段,以得到第一段24和第二段25,且将第一段24的裁剪边缘12与第二段25的裁剪边缘12拉开后在二者之间形成了第一填充区域1;

在一些实施例中,如图8所示,半导体标记制作方法包括:
如图8(a)所示,提供一周向边缘经OPC修正后的图形10;
如图8(b)所示,将图形10剪切为两段,以得到第一对准段131和第二对准段141,且将第一对准段131的裁剪边缘12与第二对准段141的裁剪边缘12拉开后在二者之间形成了第二填充区域2;
如图8(c)所示,向第二填充区域2填充第二补偿图形段后得到了第四半导体标记50。
在一些实施例中,在图8的基础上,可以将图形10剪切为左右两段,然后依据上述制作方法得到一半导体标记。

可选地,第一对准段16、第二对准段17、第三对准段18以及第四对准段19通过裁剪图形10的四个对角获得。即将图形10的中间部分进行去除,从而通过图形10的四个对角段拼接得到一个相对较小的第五半导体标记60。
在一些实施例中,如图9所示,半导体标记制作方法包括:
如图9(a)所示,提供一周向边缘经OPC修正后的图形10;

可选地,将图形10沿相垂直的两个方向裁剪为四部分,然后分别进行二次裁剪以获得第一对准段16、第二对准段17、第三对准段18以及第四对准段19。即先将图形10裁剪为四部分,然后在将裁剪出来的四部分剪小以此得到相对较小的第一对准段16、第二对准段17、第三对准段18以及第四对准段19。
在一些实施例中,如图10所示,半导体标记制作方法包括:
如图10(a)所示,提供一周向边缘经OPC修正后的图形10;

在一些实施例中,如图11所示,半导体标记制作方法包括:
如图11(a)所示,提供一周向边缘经OPC修正后的图形10;
如图11(b)所示,将图形10裁剪为四部分,以得到第一对准段161、第二对准段171、第三对准段181以及第四对准段191,且将第一对准段161的一个裁剪边缘12与第二对准段171的一个裁剪边缘12相对且间隔设置,第一对准段161的另一个裁剪边缘12与第三对准段181的一个裁剪边缘12相对且间隔设置,第二对准段171的另一个裁剪边缘12与第四对准段191的一个裁剪边缘12相对且间隔设置,第三对准段181的另一个裁剪边缘12与第四对准段191的另一个裁剪边缘12相对且间隔设置,即在第一对准段161、第二对准段171、第三对准段181以及第四对准段191之间形成了第三填充区域3;
如图11(c)所示,向第三填充区域3填充第三补偿图形段后得到了第六半导体标记70。

可选地,第二对准段102的长度等于第一对准段101的一个裁剪边缘12的长度,第三对准段103的长度等于第一对准段101的另一个裁剪边缘12的长度,即在形成第七半导体标记80后,第二对准段102和第三对准段103的部分相重叠。
在一些实施例中,如图12所示,半导体标记制作方法包括:
如图12(a)所示,提供一个或多个周向边缘经OPC修正后的图形10;

结合图13可以看出,如图13(a)所示,裁剪图形10的两侧侧部,从而形成了L形的第一对准段101。如图13(b)所示,裁剪图形10的第三个侧部,从而形成了直线形的第二对准段102。如图13(c)所述,裁剪图形10的第四个侧部,从而形成了直线形的第三对准段103。其中,第二对准段102的长度等于第一对准段101的一个裁剪边缘12的长度,第三对准段103的长度等于第一对准段101的另一个裁剪边缘12的长度。
需要说明的是,图13所示实施例中,第一对准段101、第二对准段102以及第三对准段103至少通过两个图形10裁剪获得。在一些实施例中,在裁剪出第一对准段101、第二对准段102以及第三对准段103后可以将其进行二次裁剪,即可以去掉中间段,或者可以将其由中部剪开,进行加长,此处不作限定可以根据实际需求进行调整。
可选地,第二对准段102的长度等于第一对准段101的一个裁剪边缘12的长度,第三对准段103的长度等于第一对准段101的另一个裁剪边缘12的长度减去第二对准段102的宽度,即在形成第七半导体标记80后,第二对准段102和第三对准段103的部分正好对接。
在一些实施例中,如图14所示,半导体标记制作方法包括:
如图14(a)所示,提供一个或多个周向边缘经OPC修正后的图形10;
如图14(b)所示,在一个或多个图形10的四周裁剪出第一对准段101、第二对准段102以及第三对准段103;

结合图15可以看出,如图15(a)所示,裁剪图形10的两侧侧部,从而形成了L形的第一对准段101。如图15(b)所示,裁剪图形10的第三个侧部,从而形成了直线形的第二对准段102。如图15(c)所述,裁剪图形10的第四个侧部,从而形成了直线形的第三对准段103。其中,第二对准段102的长度等于第一对准段101的一个裁剪边缘12的长度,第三对准段103的长度等于第一对准段101的另一个裁剪边缘12的长度。
需要说明的是,图15所示实施例中,第一对准段101、第二对准段102以及第三对准段103至少通过两个图形10裁剪获得。在一些实施例中,在裁剪出第一对准段101、第二对准段102以及第三对准段103后可以将其进行二次裁剪,即可以去掉中间段,或者可以将其由中部剪开,进行加长,此处不作限定可以根据实际需求进行调整。
在一个实施例中,第一对准段101和第二对准段102由同一个图形10上裁剪获得,第三对准段103由另一个图形10上裁剪获得,即由图形10上直接裁剪即可获得分别具有两个裁剪边缘12的第一对准段101、第二对准段102以及第三对准段103。
可选地,第一对准段101、第二对准段102以及第三对准段103均由同一个图形10上裁剪获得,在裁剪获得第一对准段101和第二对准段102之后,对剩余的图形10进行OPC修正,以裁剪获得第三对准段103。在由一个图形10上裁剪获得第一对准段101、第二对准段102以及第三对准段103时,则可以先裁剪获得第一对准段101和第二对准段102,继续裁剪时,则需要对裁剪后的图形10进行OPC修正,保证其某一个拐角经过OPC修正,从而使得裁剪获得的第三对准段103也仅包括两个裁剪边缘12。
可选地,第一对准段101、第二对准段102以及第三对准段103均由同一个图形10上裁剪获得,在裁剪获得第一对准段101和第二对准段102之后,裁剪剩余的图形10获得一裁剪段,对裁剪段进行OPC修正以获得第三对准段103。即在由一个图形10上裁剪获得第一对准段101、第二对准段102以及第三对准段103时,则可以先裁剪获得第一对准段101和第二对准段102,然后继续裁剪得到一个具有三个裁剪边缘12的裁剪段,并对其拐角进行OPC修正,从而得到仅包括两个裁剪边缘12的第三对准段103。
需要说明的是,对于由一个图形10上裁剪获得第一对准段101、第二对准段102以及第三对准段103的实施例,需要考虑具体半导体标记的长度,当然在某些情况下可以通过添加补偿图形段即可。
需要说明的是,图12至图15中得到的半导体标记可以为切割标识(Dicing mark)。
本公开的一个实施例还提供了一种半导体标记,包括根据上述的半导体标记制作方法获得的半导体标记。
本实施例中的半导体标记可以根据具有的尺寸要求依据上述半导体标记制作方法获得。
