Abstract: Embodiments of the invention provide a photo mask capable of simultaneously forming trenches for preventing an under-fill leakage in a process of forming an opening of a solder resist. In accordance with at least one embodiment, the photo mask includes a transparent base material having a non-transmitting film formed on one surface thereof, a semi-transmitting region formed by performing selective etching using a laser on the transparent base material, a transmitting region and a non-transmitting region formed on the transparent base material together with the semi-transmitting region, and an opening of a solder resist and trenches for preventing a leakage of an under-fill liquid or EMC mold may be simultaneously formed using the photo mask.
