ABSTRACT:
A method of changing layout of a semiconductor device includes: a step of preparing a physical layout representative of a layout of circuit constituents of a semiconductor device; a step of detecting a contradictory area in the physical layout not conforming with predetermined design rule; a step of converting the physical layout into a graphical representation by extracting nodes such as a transistor and a contact and branches interconnecting nodes from the physical layout; a step of solving the contradictory area in the graphical representation by inserting a new vector into a corresponding branch; and a step of converting the final graphical representation into a new physical representation. The method can automatically solve contradictory areas of a physical layout of a semiconductor device.
