Patent ID: 7428907

Claim:
An apparatus for removing reaction products generated on a substrate, the substrate having been subjected to a dry-etching process, the dry-etching process using a resist film as a mask to dry-etch a thin film formed on a surface of the substrate, said apparatus comprising: a) a spin mechanism for holding and rotating said substrate; b) a deionized water supply unit for supplying deionized water onto said substrate being rotated and having: b-1) a deionized water discharging unit for discharging deionized water onto said substrate being rotated; and b-2) a first driving unit for moving said deionized water discharging unit to scan said substrate with said deionized water; c) a remover liquid supply unit for supplying remover liquid whose temperature is adjusted to become higher than the room temperature onto said substrate being rotated to remove said residuary pollution and having: c-1) a remover liquid discharging unit for discharging said remover liquid onto said substrate being rotated; c-2) a second driving unit for moving said remover liquid discharging unit to scan said substrate with said remover liquid; and c-3) a first temperature controller for controlling a temperature of said remover liquid; and d) a controller configured to: i) move a reach point of said remover liquid whose temperature is higher than the room temperature on a substrate along a path connecting a rotation center of said substrate and a rotation circle defined by an edge of the substrate being rotated by moving said remover liquid discharging unit by said second driving unit and by rotating said substrate by said spin mechanism, ii) spin off remover liquid on said substrate by rotating said substrate by said spin mechanism after supplying remover liquid, and iii) move a reach point of said deionized water on a substrate along a path connecting a rotation center of said substrate and a rotation circle defined by an edge of the substrate being rotated by moving said deionized water discharging unit by said first driving unit and by rotating said substrate by said spin mechanism after spinning off the remover liquid.
