Abstract: A method of manufacturing a pattern structure is provided. The method includes forming a fine pattern on a wafer, cutting the wafer by irradiating the wafer with a laser while changing a focal depth of the laser, thereby forming a unit pattern structure having a fine pattern, and bonding cutting surfaces of at least two unit pattern structures. The cutting of the wafer comprises moving a focal position of the laser in a horizontal direction and changing the focal depth of the laser, such that the unit pattern structure has a cutting surface profile in which a first surface of the unit pattern structure on which the fine pattern is formed protrudes, in a direction substantially parallel to the first surface, from a second surface of the unit pattern structure that is opposite to the first surface.
