Publication number: 20090078580Abstract: As a barrier metal film, a Ti film or a Ta film is formed by sputtering method on a substrate. On top of this barrier metal film there is formed a nitride film by sputtering method. A Cu film is then formed on the nitride film by CVD method and thereafter anneal processing is performed at 100 to 400° C. In this manner, by forming the Cu film, the adhesiveness between the barrier metal film and the Cu film improves.Type: ApplicationFiled: December 4, 2006Publication date: March 26, 2009Applicant: ULVAC, Inc.Inventors: Tomoyuki Yoshihama, Masamichi Harada, Satoru Toyoda, Harunori Ushikawa
