Title: Substrate treating device
Inventor: MIYA KATSUHIKO
IPC: B08B5/00
Filed: 2001-03-22
Abstract: PROBLEM TO BE SOLVED: To provide a substrate treating device with such advantages as high in throughput the inhibition of increase in the consumption of an inert gas, and a satisfactory treatment finish condition are achieved. SOLUTION: A substrate W is horizontally retained by a chuck pin 14 set upright on a spin base 10, and an atmosphere shut-off plate 30 is mounted above the spin base 10. On the lower face side of the atmosphere shut-off plate 30, a columnar projecting part 31 with a surface region diametrally smaller than the substrate W is formed. The substrate W is made to undergo treatments such as cleaning and drying by supplying a treating solution or a nitrogen gas to the substrate W from its upper and lower face sides while it is rotated with the atmosphere shut-of plate 30 kept in a close proximity to the former. The projecting part 31 can be brought into a close proximity with the substrate W without coming into contact with the chuck pin 14, so that a space between the atmosphere shut-off plate 30 and the substrate W can be narrowed.  Thus, the nitrogen gas can be efficiently supplied to inhibit the increase in the consumption of nitrogen gas and a drying time is shortened to prevent bounced-back contaminants from adhering to the substrate W.
