    • A method for wafer alignment includes the following steps. First, a wafer including a first material layer and a second material layer on the top of the first material layer is provided, wherein the first material layer includes a first alignment mark. Then, the wafer is aligned in an exposure tool. After that, the second material layer is patterned to form a second alignment mark. Finally, an offset distance between the first alignment mark and the second alignment mark is measured in the exposure tool.
    • 晶片对准的方法包括以下步骤。 首先,提供在第一材料层的顶部包括第一材料层和第二材料层的晶片,其中第一材料层包括第一对准标记。 然后,晶片在曝光工具中对准。 之后,将第二材料层图案化以形成第二对准标记。 最后,在曝光工具中测量第一对准标记和第二对准标记之间的偏移距离。

    • A method for forming a semiconductor device is disclosed. A substrate comprising a structural layer thereon is provided. A hard mask layer is formed on the structural layer. A photoresist layer is formed on the hard mask layer. The photoresist layer is patterned to from a plurality of main photoresist patterns and at least one dummy photoresist pattern between the main photoresist patterns or adjacent to one of the main photoresist patterns, wherein width of the dummy photoresist pattern is less than that of the main photoresist patterns. Two main photoresist patterns are separated with each other by a first opening, and two dummy photoresist patterns are separated with each other by a second opening. Width of the second opening is less than that of the first opening. The hard mask layer is patterned using the patterned photoresist layer as a mask. The structural layer is patterned using the patterned hard mask layer as a mask.
    • 公开了一种用于形成半导体器件的方法。 提供了包括其上的结构层的衬底。 在结构层上形成硬掩模层。 在硬掩模层上形成光致抗蚀剂层。 光致抗蚀剂层从多个主光致抗蚀剂图案和主光致抗蚀剂图案之间的至少一个伪光致抗蚀剂图案图案化,或者与主光致抗蚀剂图案之一相邻,其中,伪光刻胶图案的宽度小于主光致抗蚀剂图案的宽度 模式。 两个主要的光致抗蚀剂图案通过第一开口彼此分离,并且两个伪光刻胶图案通过第二开口彼此分离。 第二开口的宽度小于第一开口的宽度。 使用图案化的光致抗蚀剂层作为掩模来对硬掩模层进行图案化。 使用图案化的硬掩模层作为掩模来对结构层进行图案化。
