Patent number: 7530749Abstract: A coating and developing system prevents wetting its component units with water when the coating and developing system forms a resist film on a substrate and processes the substrate processed by immersion exposure by a developing process. A substrate having a surface coated with a resist film and processed by immersion exposure is placed on a substrate support device and a liquid detector detects at least the liquid formed a liquid film for immersion exposure and remaining on the surface of the substrate. A decision is made as to whether or not the substrate needs to be dried on the basis of the result of detection made by the liquid detector. If it is decided that the substrate needs to be dried, the substrate is dried by a drying means. Thus wetting the interior of the coating and developing system with water can be prevented. Since only substrates that need to be dried are subjected to a drying process, the coating and developing system is able to operate at a high throughput.Type: GrantFiled: December 3, 2004Date of Patent: May 12, 2009Assignee: Tokyo Electron LimitedInventors: Taro Yamamoto, Osamu Hirakawa

Publication number: 20080008973Abstract: The invention provides a method capable of preventing the occurrence of collapse of resist pattern accompanied by size reduction in pattern dimensions can be prevented when processing a resist film having been exposed and formed on the surface of a substrate, and in which there is no fear that posterior processes are adversely affected. In the step of processing a resist film having been exposed and formed on the surface of a substrate, a developer mixed with a hydrophobizing agent is fed onto the resist film on the substrate surface; or before rinsing the resist film having been processed, a solvent containing a hydrophobic resin is fed onto the resist film on the substrate surface. Thus, a resist exposed surface is made to be hydrophobic before the rinsing, and thereafter rinsed and dried by spinning.Type: ApplicationFiled: July 10, 2007Publication date: January 10, 2008Inventors: Tomohiro GOTO, Masakazu SANADA, Osamu TAMADA

Patent number: 7316515Abstract: In a liquid processing apparatus a spin chuck holds a wafer having a surface supplied with a liquid to be applied through a nozzle receiving the liquid through a feed path and whether the liquid passing through the feed path has fluctuation is detected by a fluctuation detection device. Thus the liquid's condition in the feed path can be determined significantly accurately. Supplying the substrate with the liquid without fluctuation allows the substrate to receive the liquid in an optimal condition. A satisfactory liquid process can thus be performed.Type: GrantFiled: July 25, 2005Date of Patent: January 8, 2008Assignee: Tokyo Electron LimitedInventors: Shouichi Terada, Nobuyuki Sata
