    摘要: An automated wiring pattern layout method is provided. With this method, a first wiring pattern is generated with width W and extending in a first direction, and a second wiring pattern is generated with width W and extending in a direction perpendicular to the first wiring pattern in a manner such that the end thereof ends at the end portion of the first wiring pattern. Moreover, an overlapping region is generated by bending an end of either one of the first or the second wiring pattern at a right angle to produce an L-shaped extension and overlaying the first and the second wiring pattern, and a rectangular-shaped VIA pattern is generated at the overlapping region.

    摘要: In a pattern correction method, design layout data of a pattern designed by an automated layout unit is entered. An environmental profile is determined based on whether or not another graphics pattern exists at the surroundings of each correction target cell included in the entered design layout data. A target cell name is replaced with a prescribed cell name of correction pattern corresponding to the determined environmental profile by referencing a cell replacement table. An OPC correction pattern corresponding to the replaced cell name is imported from a cell library.
