Abstract
A method for filling patterns includes the steps of: providing a substrate having a cell region defined thereon; forming main patterns on the substrate and within the cell region; and filling first dummy patterns adjacent to the main patterns. Preferably, each of the first dummy patterns comprises a first length along X-direction between 2 μm to 5 μm and a second length along Y-direction between 3 μm to 5 μm.
