Abstract
In a method of designing a mask layout, a wiring region for forming a metal wire is established, the wiring region having at least a standard width. Contact regions for forming contacts electrically connected to the metal wire are established in the wiring region. The contact regions adjacent to each other are grouped to divide the wiring region into a first region and a second region including the contact regions. First dummy regions are established in the first region, the first dummy regions corresponding to regions for forming first dummy patterns. Second dummy regions are established among the contact regions in the second region, the second dummy regions corresponding to regions for forming second dummy patterns.
