Publication number: 20040242127Abstract: A slurry feeding apparatus includes closed slurry bottle, piping, wet nitrogen generator, wet nitrogen supply pipe, suction and spray nozzles, temperature regulator, flow rate control valves, slurry delivery pump and controller for controlling the operation and flow rate of the slurry delivery pump. While a wafer is being polished by a CMP polisher, the controller continuously operates the pump. On the other hand, while the polisher is idling, the controller starts and stops the pump intermittently at regular intervals. No stirrer like a propeller is inserted into the slurry bottle, but the slurry is stirred up by spraying the slurry through the spray nozzle.Type: ApplicationFiled: June 14, 2004Publication date: December 2, 2004Applicant: Matsushita Electric Industrial Co., Ltd.Inventors: Akihiro Tanoue, Yoshiharu Hidaka, Shin Hashimoto

Publication number: 20040106531Abstract: The cleaning composition for removing resists includes a salt of hydrofluoric acid and a base not containing a metal (A component), a water-soluble organic solvent (B1 component), at least one acid selected from a group consisting of organic acid and inorganic acid (C component), water (D component), and optionally an ammonium salt (E1 component), and its hydrogen ion concentration (pH) is 4-8. Thus, in the manufacturing process of a semiconductor device such as a copper interconnecting process, removing efficiency of resist residue and other etching residue after etching or ashing improves, and corrosion resistance of copper and insulating film also improves.Type: ApplicationFiled: July 11, 2003Publication date: June 3, 2004Applicants: Renesas Technology Corp., Matsushita Electric Industrial Co., Ltd., EKC Technology K.K.Inventors: Itaru Kanno, Yasuhiro Asaoka, Masahiko Higashi, Yoshiharu Hidaka, Etsuro Kishio, Tetsuo Aoyama, Tomoko Suzuki, Toshitaka Hiraga, Toshihiko Nagai

Patent number: 6428398Abstract: It is arranged such that the least common multiple of two numbers m and n of which one is prime to the other, is made as large as possible where the number m is the rotational speed (rpm) of a platen with a polishing pad affixed thereto and the number n is the rotational speed (rpm) of a carrier with a wafer mounted thereon. As a result of such arrangement, it is not until the platen completes m revolutions that a point on the polishing pad that comes into contact with a fixed point on the wafer returns to the original contact point with the fixed point at the start of polishing, and the resulting trajectory is therefore spread uniformly over the polishing pad.Type: GrantFiled: December 18, 2000Date of Patent: August 6, 2002Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Shin Hashimoto, Yoshiharu Hidaka
