  • Patent number: 6730620
    Abstract: Processing of applying ultraviolet rays to a front face of an insulating film material formed on a wafer W is performed, whereby a contact angle of the front face thereof becomes smaller. Accordingly, when an insulating film material is applied on the aforesaid front face, the material smoothly spreads, and projections and depressions never occur on a front face of an upper layer insulating film material. Thereby, it is possible to form the insulating film thick and flatter on a substrate.
    Type: Grant
    Filed: April 30, 2002
    Date of Patent: May 4, 2004
    Assignee: Tokyo Electron Limited
    Inventors: Kei Miyazaki, Yuichiro Uchihama, Kenji Yasuda, Kiminari Sakaguchi, Shinji Nagashima
