Patent number: 9673144Abstract: A semiconductor device has a resistor area and wiring area selectively disposed on a semiconductor substrate. In this semiconductor device, a second interlayer insulating film is formed above the semiconductor substrate, and a thin-film resistor is disposed on the second interlayer insulating film in the resistor area. Vias that contact the thin-film resistor from below are formed in the second interlayer insulating film. A wiring line is disposed on the second interlayer insulating film in the wiring area. A dummy wiring line that covers the thin-film resistor from above is disposed in a third wiring layer that is in the same layer as the wiring line, and an insulating film is interposed between the thin-film resistor and the dummy wiring line.Type: GrantFiled: December 21, 2015Date of Patent: June 6, 2017Assignee: ROHM CO., LTD.Inventors: Isamu Nishimura, Michihiko Mifuji, Kazumasa Nishio

Patent number: 9511402Abstract: The invention enhances a cooling effect on a press die for hot press. A lower die includes a first base, a second base mounted on the first base and having an opening in the center, a support table provided in the opening of the second base, and a die portion detachably mounted on the support table and including die pieces. The die portion is divided in die pieces disposed adjoining each other, and cold water pipes are provided in the die pieces respectively. The cold water pipes are bent in a U shape and inserted in the die pieces respectively, and extended downward from the lower ends of the die pieces respectively. The cold water pipes have cooling water injection ends and cooling water ejection ends in a space between the first base and the support table.Type: GrantFiled: March 13, 2013Date of Patent: December 6, 2016Assignee: TOA Industries Co., Ltd.Inventors: Koji Hayashi, Taichi Shimizu, Kazumasa Nishio
