Publication number: 20180155821Abstract: The magnetron sputtering apparatus SM has: a vacuum chamber; and a cathode unit C detachably mounted on the vacuum chamber. The cathode unit has: a target which is disposed to face an inside of the vacuum chamber; and a magnet unit disposed to that side of the target which is opposite to a sputtering surface, thereby generating a leakage magnetic field on a side of the sputtering surface. The sputtering apparatus SM of this invention, having the above-mentioned arrangement has a drive source for driving the magnet unit to rotate with a target center serving as a center of rotation while the target is sputtered to form a film on a to-be-processed substrate. Auxiliary magnet units which cause a leakage magnetic field to function on the inside of the vacuum chamber are locally disposed on an external wall of the vacuum chamber or of a housing H of the cathode unit.Type: ApplicationFiled: May 11, 2016Publication date: June 7, 2018Applicant: ULVAC, INC.Inventors: Shinya Nakamura, Yoshinori Fujii

Patent number: 9972479Abstract: A target assembly is provided which is capable of preventing abnormal discharging from being generated between a projected portion of a backing plate and a side surface of a target, and which is also capable of surely preventing a bonding material that bonds the target and the backing plate together from seeping to the outside. The backing plate has a projected portion which is projected outward beyond an outer peripheral end of the target, and an annular shield plate is disposed to lie opposite to the projected portion so as to enclose the target in a state in which the target assembly is assembled onto a sputtering apparatus (SM). That portion of the backing plate to which the target gets bonded is defined as a bonding portion, and this bonding portion is protruded relative to the projected portion.Type: GrantFiled: June 18, 2015Date of Patent: May 15, 2018Assignee: ULVAC, INC.Inventors: Shinya Nakamura, Yoshihiro Ikeda, Yoshinori Fujii, Yuusuke Miyaguchi

Patent number: 8956513Abstract: There is provided a substrate processing method, in which a throughput can be improved even in case the time for recovery processing for restoring the state of a processing chamber is longer than the time for predetermined processing to be performed in the processing chamber. Substrates are alternately transferred to two processing chambers C, D, and the same film forming processing is performed on the substrates in the processing chambers C, D in parallel with each other. When the number of substrates processed in the processing chamber C has reached a predetermined number (11 substrates), dummy sputtering processing in the film forming chamber C is started and also 23rd-25th substrates of the first lot are transferred to the film forming chamber D to thereby perform film forming processing until the dummy sputtering processing is finished.Type: GrantFiled: July 15, 2010Date of Patent: February 17, 2015Assignee: Ulvac, Inc.Inventors: Shinya Nakamura, Yoshinori Fujii, Hideto Nagashima
