Summary: | PURPOSE: An apparatus generating a horizontal and vertical mask layout concerning bipolar light, and a method therefor are provided to form horizontal and vertical masks by using a bipolar light source. CONSTITUTION: A target pattern including a plurality of features having horizontal and vertical edges is identified. A horizontal mask is formed based on the target pattern. A vertical mask is formed based on the target pattern. A shielding operation is performed by replacing more than one of the vertical edges of the features in the target pattern with a shield in the horizontal mask and by replacing more than one of the horizontal edges of the features in the target pattern with a shield in the vertical mask. The width of the shield is wider than the width of a corresponding feature in the target pattern. |
