The present invention provides a shift multi-exposure method for defining a regular pattern by a photomask. The method comprises the following steps. First, a photoresist layer comprising a first region and a second region is formed on a substrate. Then, a first pattern is defined on the first region by the photomask. Next, the photomask is moved a predetermined distance, and a second pattern is defined on the second region by the photomask. Finally, development is performed to display the first pattern and the second pattern on the photoresist layer.
