A skeg mounts from the stern of a towing vessel and extends below the waterline. In response to a demand miss, a loadstore unit sends a fetch request to the next level cache. A three dimensional model is opened in which the composite part is located. Thus, an optical waveguide device integrated module and a method of manufacturing the same are provided, in which a semiconductor laser and a planar optical waveguide device are mounted with their positions in the height direction controlled with high precision.
