    • According to one embodiment, firstly, an inversion pattern having a periodic pattern in which a first line pattern and a space are inversed and a non-periodic pattern arranged at an interval which is substantially equal to the width of the first line pattern from the end of the periodic pattern is formed above a processing object so as to correspond to the plurality of spaces between a plurality of first line patterns in a first pattern and the space between the first pattern and a second pattern. Next, a sidewall film is formed around the inversion pattern, and the periodic pattern is removed selectively. Thereafter, the processing object is etched using the sidewall pattern formed of the sidewall film and the non-periodic pattern surrounded by the sidewall film as masks.
    • 根据一个实施例,首先,具有其中第一线图案和空间被倒置的周期性图案的反转图案和以从第一个第一线图案的宽度基本上等于第一线图案的宽度的间隔排列的非周期性图案 在处理对象之上形成周期性图案,以便对应于第一图案中的多个第一线图案与第一图案与第二图案之间的空间之间的多个间隔。 接下来,在反转图案周围形成侧壁膜,并且选择性地去除周期性图案。 此后,使用由侧壁膜形成的侧壁图案和由侧壁膜包围的非周期性图案作为掩模来蚀刻处理对象。

    • A pattern forming method includes forming a first photoresist on an underlying region, forming a second photoresist on the first photoresist, the second photoresist having an exposure sensitivity which is different from an exposure sensitivity of the first photoresist, radiating exposure light on the first and second photoresists via a photomask including a first transmissive region and a second transmissive region which cause a phase difference of 180° between transmissive light components passing therethrough, the first transmissive region and the second transmissive region being provided in a manner to neighbor in an irradiation region, and developing the first and second photoresists which have been irradiated with the exposure light, thereby forming a structure includes a first region where the underlying region is exposed, a second region where the first photoresist is exposed and a third region where the first photoresist and the second photoresist are left.
    • 图案形成方法包括在下面的区域上形成第一光致抗蚀剂,在第一光致抗蚀剂上形成第二光致抗蚀剂,第二光致抗蚀剂具有不同于第一光致抗蚀剂的曝光灵敏度的曝光灵敏度, 通过包括第一透射区域和第二透射区域的光掩模进行光刻,所述第一透射区域和第二透射区域在穿过其中的透射光分量之间产生180°的相位差,第一透射区域和第二透射区域以照射区域相邻的方式设置, 以及显影已经用曝光光照射的第一和第二光致抗蚀剂,由此形成结构,其包括下部区域被暴露的第一区域,第一光致抗蚀剂被曝光的第二区域和第一光致抗蚀剂 剩下第二光致抗蚀剂。
