Patent number: 6756299Abstract: A process for fabricating a semiconductor device, which reduces the number of steps required for forming a via hole and a wiring trench in the insulating film comprised of a low dielectric-constant insulating material, resulting in a lower cost for fabrication and a shorter turn around time, is provided. A photosensitive silazane film is exposed and developed to form a hard mask on an interlayer dielectric. The hard mask defines a wiring pattern for a wiring layer and a position of a via hole. Then, a resist film is formed on the interlayer dielectric to form a resist mask having a via hole pattern, and part of a via hole is formed using the resist mask. The interlayer dielectric is subjected to anisotropic etching using the hard mask to form a wiring trench and to allow the via hole to reach the wiring layer, and the wiring layer is exposed.Type: GrantFiled: November 1, 2002Date of Patent: June 29, 2004Assignee: Sony CorporationInventor: Naoki Nagashima

Patent number: 6507698Abstract: An inactive gas is introduced into an organic material evaporation source to place a thin organic film material in the organic material evaporation source in an atmosphere having a relatively high pressure, and the temperature of the thin organic film material is increased up to a certain temperature. Then, the organic material evaporation source is evacuated to lower the pressure around the thin organic film material for thereby causing the thin organic film material to emit a vapor. Since no wasteful vapor is emitted from the thin organic film material, the thin organic film material is effectively utilized. Because the inactive gas acts as a heating medium, the temperature of the thin organic film material is increased at a high rate, and the thin organic film material is uniformly heated. When the temperature of the thin organic film material is lowered in an inactive gas atmosphere, it can be lowered at a high rate.Type: GrantFiled: February 28, 2001Date of Patent: January 14, 2003Assignee: Nihon Shinku Gijutsu Kabushiki KaishaInventors: Naoki Nagashima, Natsuki Takahashi, Toshio Negishi
