    • Provided is a method for optical proximity correction for use in manufacturing highly resolved semiconductor chips. The method includes setting a target layout; setting a peculiar area; sorting the peculiar area from the target layout; generating a marking layer; resetting a critical dimension (CD) of a peculiar pattern; compensating an optical proximity effect; and manufacturing a mask. The method provides an improved way of improving more accurately CD uniformity by performing optical proximity correction with respect to a pattern to which a bias rule is difficult to apply due to an absence of an adjacent pattern.
    • 提供一种用于制造高分辨率半导体芯片的光学邻近校正方法。 该方法包括设置目标布局; 设置一个特殊区域; 从目标布局中分选特有区域; 产生标记层; 复位特殊模式的关键维度(CD); 补偿光学邻近效应; 并制造面具。 该方法提供了通过对由于不存在相邻图案而难以应用偏置规则的图案执行光学邻近校正来提高更准确地CD均匀性的改进方法。
