    • A photomask pattern on a substrate is provided. The photomask pattern comprises a main pattern and a sub-resolution assistant feature. The sub-resolution assistant feature is located on the sides of the main pattern. Furthermore, the sub-resolution assistant feature comprises a first assistant feature and a second assistant feature. The first assistant feature is formed close to the main pattern and the second assistant feature is formed further away from the main pattern but adjacent to the first assistant feature. There is a phase difference of 180° between the first assistant feature and the main pattern. Similarly, there is a phase difference of 180° between the second assistant feature and the first assistant feature. Since the main pattern is bordered by reverse-phase assistant feature, exposure resolution of the photomask is increased.
    • 提供了基板上的光掩模图案。 光掩模图案包括主图案和子分辨率辅助特征。 子分辨率辅助功能位于主图案的两侧。 此外,子分辨率辅助特征包括第一辅助特征和第二辅助特征。 第一辅助功能形成在主模式附近,第二辅助功能远离主模式形成,但与第一辅助功能相邻。 第一辅助特征与主图案之间存在180°的相位差。 类似地,在第二辅助特征和第一辅助特征之间存在180°的相位差。 由于主图案由反相辅助功能界定,因此增加了光掩模的曝光分辨率。
