Abstract: A method of designing a layout of an integrated circuit includes generating floorplan data by performing floorplan based on input data for the integrated circuit, searching for a path between a first point and a second point, which are specified, the searching based on the floorplan data, and positioning components of the layout based on a result of the searching. The searching for the path includes distinguishing based on the floorplan data a first region where routing is possible from a second region where the routing is not possible, receiving position data on the first point and the second point, and searching for a shortest path between the first point and the second point, on the first region.

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.
