    [0051]具体实施方式
    [0052]本申请描述了多个实施例,但是该描述是示例性的,而不是限制性的,并且对于本领域的普通技术人员来说显而易见的是,在本申请所描述的实施例包含的范围内可以有更多的实施例和实现方案。尽管在附图中示出了许多可能的特征组合,并在具体实施方式中进行了讨论,但是所公开的特征的许多其它组合方式也是可能的。除非特意加以限制的情况以外,任何实施例的任何特征或元件可以与任何其它实施例中的任何其他特征或元件结合使用,或可以替代任何其它实施例中的任何其他特征或元件。
    [0053]本申请包括并设想了与本领域普通技术人员已知的特征和元件的组合。本申请已经公开的实施例、特征和元件也可以与任何常规特征或元件组合,以形成由权利要求限定的独特的发明方案。任何实施例的任何特征或元件也可以与来自其它发明方案的特征或元件组合,以形成另一个由权利要求限定的独特的发明方案。因此,应当理解,在本申请中示出和/或讨论的任何特征可以单独地或以任何适当的组合来实现。因此,除了根据所附权利要求及其等同替换所做的限制以外,实施例不受其它限制。此外,可以在所附权利要求的保护范围内进行各种修改和改变。
    [0054]此外,在描述具有代表性的实施例时,说明书可能已经将方法和/或过程呈现为特定的步骤序列。然而,在该方法或过程不依赖于本文所述步骤的特定顺序的程度上,该方法或过程不应限于所述的特定顺序的步骤。如本领域普通技术人员将理解的,其它的步骤顺序也是可能的。因此,说明书中阐述的步骤的特定顺序不应被解释为对权利要求的限制。此外,针对该方法和/或过程的权利要求不应限于按照所写顺序执行它们的步骤,本领域技术人员可以容易地理解,这些顺序可以变化,并且仍然保持在本申请实施例的精神和范围内。
    [0055]本申请实施例提供了一种晶圆光刻参数获取方法,如图1所示,所述方法可以包括步骤S101-S104:
    [0056]S101、获取预先建立的全透明相移掩模参数与晶圆参数对应关系的数据库;
    [0057]S102、获取目标晶圆参数,并根据所述数据库和所述目标晶圆参数获取目标全透明相移掩模参数;
    [0058]S103、根据所述目标全透明相移掩模参数进行全透明相移掩模光学仿真,以获取使得仿真结果满足预设要求的仿真参数以及最终目标全透明相移掩模参数;
    [0059]S104、将所述仿真参数作为晶圆光刻工艺参数,并将所述最终目标全透明相移掩模参数作为晶圆光刻所需的全透明相移掩模的参数。
    [0060]在本申请的示例性实施例中,已知相移掩模技术是一种分辨率增强技术,而全透明相移掩模【与无铬相移掩模相似,不同的是,全透明相移掩模用于曝光的区域没有铬(该区域均为石英),其他区域均是有铬的】相比现有二值掩模和衰减相移掩模,分辨率提升更强,能提供更好的图形对比度。全透明相移掩模由于掩模蚀刻石英时无停止层,蚀刻深度易受到图形密集度的影响,从而使图形密集区和非密集区相位差不均匀,其使用存在一定局限性。但是等间距及周期线条的全透明相移掩模能使最终晶圆线条周期减半,如图2所示,这种现象有可能在光刻特殊工艺得到应用,同时,增大了制备相同晶圆线条周期时对应的全透明掩模尺寸从而减小了掩模制造成本,且等周期线条的全透明掩模蚀刻工艺更好控制。
    [0061]在本申请的示例性实施例中,基于全透明相移掩膜提出了一种晶圆光刻参数获取方法,首先建立全透明相移掩模参数与晶圆参数对应关系的数据库;并基于该数据库进行全透明相移掩模光学仿真,以通过仿真获取合适的晶圆光刻参数。

    [0064]在本申请的示例性实施例中,全透明相移掩模参数与晶圆参数对应关系的数据库可以是指全透明相移掩模线宽及间距尺寸与晶圆线宽及间距尺寸对应关系数据库。
    [0065]在本申请的示例性实施例中,建立全透明相移掩模参数与晶圆参数对应关系的数据库,可以包括:
    [0066]按照瑞利公式确定不同光刻机所能达到的晶圆线宽最小极限,并根据预设倍数关系确定与所述晶圆线宽最小极限对应的全透明相移掩模最小线宽;确定预先设置的晶圆最大线宽,并根据所述预设倍数关系确定与所述晶圆最大线宽对应的全透明相移掩模最大线宽;从而确定全透明相移掩模最大线宽;和/或,
    [0067]按照瑞利公式确定不同光刻机所能达到的晶圆间距尺寸最小极限,并根据预设倍数关系确定与所述晶圆间距尺寸最小极限对应的全透明相移掩模最小间距尺寸;确定预先设置的晶圆最大间距尺寸,并根据所述预设倍数关系确定与所述晶圆最大间距尺寸对应的全透明相移掩模最大间距尺寸;从而确定全透明相移掩模最大间距尺寸。
    [0068]在本申请的示例性实施例中,所述预设倍数关系可以包括:
    [0069]全透明相移掩模线宽为晶圆线宽的a倍;
    [0070]全透明相移掩模间距尺寸为晶圆间距尺寸的a倍;
    [0071]其中,a为正整数;当晶圆和全透明相移掩模为一比一结构时,a包括2。
    [0072]在本申请的示例性实施例中,晶圆以及全透明相移掩膜的线宽和间距尺寸均是一比一结构。根据全透明相移掩模空间像频率加倍特性,可以建立全透明相移掩模线宽及间距尺寸与晶圆线宽及间距尺寸的二倍关系;因此上述的数据库为晶圆线条周期减半数据库,如表1所示。
    [0073]表1
    [0074]在本申请的示例性实施例中,可以通过首先确定出晶圆的线宽和间距尺寸的最小值和最大值,再根据上述的二倍关系确定出全透明相移掩膜的线宽和间距尺寸的最小值和最大值,从而可以确定出晶圆和全透明相移掩膜的线宽和间距尺寸的最小值和最大值之间不同数值的对应关系,组成满足最小线宽至最大线宽,以及最小间距尺寸至最大间距尺寸的一定范围内的对应关系数据库。其中,在最初建立的数据库中,每一组全透明相移掩膜的线宽和间距尺寸,与所对应的一组晶圆的线宽和间距尺寸为二倍关系。
    [0075]在本申请的示例性实施例中,例如,全透明相移掩模线宽及间距尺寸为80nm和80nm,对应地,晶圆线宽及间距尺寸为40nm和40nm。
    [0076]在本申请的示例性实施例中,全透明相移掩模结构示意图如图3所示。其中,π和0代表全透明相移掩模的相位。
    [0077]在本申请的示例性实施例中,由于不同的光刻机具有不同的性能,所能达到的晶圆线宽最小极限也不同,因此可以通过瑞利公式确定不同光刻机所能达到的晶圆线宽最小极限,从而根据二倍关系获取全透明相移掩模的线宽最小值,由于在需求范围内,目前光刻机对晶圆线宽的最大极限值没有限制,因此,可以根据不同的加工需求预先设置晶圆最大线宽,从而根据二倍关系获取全透明相移掩模的线宽最大值。
