Patent ID: 8882960

Claim:
A substrate treating apparatus for immersing and treating a rectangular substrate in a treating liquid, comprising: a treating tank for treating the substrate; transport rollers arranged in the treating tank for horizontally transporting the substrate; a supplying device for supplying a treating liquid into the treating tank from a storage tank storing the treating liquid; a draining device for draining the treating liquid from the treating tank to the storage tank; a liquid level adjusting mechanism for setting a level of the treating liquid in the treating tank at a position above the transport rollers; a treating liquid discharge device for discharging the treating liquid from below the transport rollers, with the substrate immersed in the treating liquid stored in the treating tank, thereby to raise the substrate to a position spaced above the transport rollers; and anti-surfacing members for preventing the substrate from rising up to said level of the treating liquid stored in the treating tank, wherein the anti-surfacing members have inclined surfaces facing downward toward said transport rollers, said inclined surfaces being arranged in positions for contacting a pair of edges of the substrate to block said substrate from rising upward toward said level of the treating liquid.
