    摘要： Provided are a heat spreader for a semiconductor device, which can be joined such that a multitude of pin-shaped fins are not easily fractured even when the heat spreader for a semiconductor device is incorporated in a heat dissipation structure for a semiconductor device, in which direct cooling is performed by using water, and a method for manufacturing the heat spreader for a semiconductor device. The heat spreader (1) for a semiconductor device comprises: a plurality of columnar members (13) joined onto at least one of surfaces of a plate-like member (11, 12) by stud welding; and a joining layer (14) formed between the plate-like member (11, 12) and the columnar members (13). The plate-like member (11, 12) includes a base material (11) and surface layers (12). The surface layers (12) and the columnar members (13) are made of a material containing aluminum or an aluminum alloy. A thickness of the plate-like member (11, 12) is 0.5 mm through 6 mm and a thickness of each of the surface layers (12) is 0.1 mm through 1 mm. The joining layer (14) has a joining interface (15) on a boundary with the plate-like member (11, 12). A proportion of an area of the joining interface (15) being present in the surface layer (12) is greater than or equal to 50% and less than or equal to 100%, converted in terms of a plane projected to the one of the surfaces of the plate-like member.

    摘要： A casting nozzle suited to manufacture a casting material of pure magnesium or magnesium alloy is provided. A nozzle 1 is utilized to manufacture a casting material 100 by supplying molten metal to a portion between rolls 10 which become a casting die, and arranged so that a pouring port 4 is located between a pair of rolls 10 opposed to other. This nozzle 1 includes a main body 1a formed of oxide material such as alumina, and a coating layer 3 which is provided on the inner surface of the main body 1a which comes into contact the molten metal, and formed of material that does not include oxygen substantially. Since the main body 1a does not come into direct contact with the molten metal due to the coating layer 3, it is possible to prevent oxygen included in the main body 1a from reacting with the molten metal. Further, in the nozzle 1, a casting die contact portion 2 which comes into contact with the rollers 10 is formed of thermal insulation material, whereby it is prevented that the molten metal in the nozzle 1 is cooled through the casting die contact portion 2 by the rollers 10.
