Patent number: 7042100Abstract: A semiconductor device includes an insulating film. On this insulating film are formed an interconnection trench communicating with a semiconductor element and a pad trench communicating with the interconnection trench. In the pad trench, a protrusion is formed by leaving one part of the insulating film. A conductive film is formed over the insulating film including the interconnection and pad trenches. Thereafter, the conductive film is removed by a CMP process. At this time, the protrusion serves to prevent the conductive film in the pad trench from being over-polished.Type: GrantFiled: February 22, 2005Date of Patent: May 9, 2006Assignee: Rohm Co., LtdInventors: Koji Yamamoto, Nobuhisa Kumamoto, Muneyuki Matsumoto

Patent number: 6992006Abstract: The present invention provides a method for fabricating a semiconductor device which initially performs chemical mechanical polishing with respect to a metal film made of copper formed on a semiconductor substrate to form wires composed of the metal film on the semiconductor substrate and subsequently removes a wire-to-wire bridge occurring during the formation of the wires and remaining on the semiconductor substrate to cause unneeded conduction between the wires adjacent to each other. The removal of the wire-to-wire bridge is performed by oxidizing the wire-to-wire bridge into a copper oxide by using an aqueous hydrogen peroxide and then dissolving the copper oxide by using an oxalic acid. This allows the removal of the wire-to-wire bridge without damaging the main bodies of the wires.Type: GrantFiled: August 23, 2004Date of Patent: January 31, 2006Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Hideki Otsuka, Tsuyoshi Miyata, Muneyuki Matsumoto, Hiroshi Kawano

Publication number: 20040248401Abstract: A TaN film and a Cu film are deposited successively over an insulating film formed with trenches. Then, a first CMP process is performed by using a slurry having a polishing rate for Cu sufficiently higher than a polishing rate for TaN and containing an agent for forming a protective film for Cu in a sufficient amount. As a result, the upper surface of the portion of the Cu film located in each of the trenches is positioned flush with the upper surface of TaN. Then, a second CMP process is performed under such a condition that the polishing rate for Cu is equal to or higher than the polishing rate for TaN, thereby forming Cu wires. By properly changing conditions for the second CMP process in accordance with the level of the upper surface of the Cu film, the upper surface of the Cu film is positioned flush with or lower in level than the upper surface of the insulating film after the second CMP process so that the occurrence of defective wiring is reduced.Type: ApplicationFiled: June 3, 2004Publication date: December 9, 2004Applicant: MATSUSHITA ELECTRIC INDUSTRIAL CO., LTD.Inventors: Mitsunari Satake, Muneyuki Matsumoto

Patent number: 6518150Abstract: In a wafer treating process, an impurity ion implanting, an Si+ ion implanting and an annealing are successively effected on an Si substrate. In the impurity ion implanting, an impurity ion is introduced into the Si substrate by ion implantation using a projected range. In the Si+ ion implanting, an Si+ ion is introduced into the Si substrate subjected to the impurity ion implanting by ion implantation using a projected range smaller than the above projected range. In the annealing, the Si substrate subjected to the impurity ion implanting and the Si+ ion implanting is subjected to heat treatment. As a result, the Si+ ion introduced in the Si+ ion implanting is bonded to each vacancy defect developed in the impurity ion implanting in the wafer treating process, so that the occurrence of crystal defects due to the vacancy defects is inhibited.Type: GrantFiled: November 29, 1999Date of Patent: February 11, 2003Assignee: Oki Electric Industry Co., Ltd.Inventor: Muneyuki Matsumoto
