Moreover, the present invention provides a method of forming a silicon film comprising the step of applying such a high order silane composition onto a substrate.Type: GrantFiled: April 22, 2003Date of Patent: May 29, 2007Assignees: Seiko Epson Corporation, JSR CorporationInventors: Takashi Aoki, Masahiro Furusawa, Yasuo Matsuki, Haruo Iwasawa, Yasumasa Kateuchi
