Claim:
1. A substrate treating apparatus comprising: a chamber having at least a top surface; a support member within the chamber configured to support a substrate; an exhaust member configured to exhaust a gas within an inner space of the chamber to an outside of the chamber, the exhaust member having an inner tube and an outer tube, the inner tube including a first end and a second end, the outer tube being detachably connected to the top surface of the chamber while when fumes contained in a gas are removed, the first end of the inner tube extending from the top surface of the chamber a lesser length than the outer tube extends from the top surface of the chamber such that the outer tube surrounds the inner tube with a trap space therebetween along the top surface of the chamber to collect the fumes; and a guide member, the guide member being a disc having a hollow center such that the second end of the inner tube passes through the hollow center of the guide member and suspends the guide member therefrom within the chamber, a diameter of the guide member being less than a diameter of the chamber and larger than a diameter of the substrate such that the gas flows about a top surface and a bottom surface of the guide member, then through the second end of inner tube penetrating the hollow center of the guide member, then through the outer tube to the outside while the fumes contained in the gas are collected in the trap space along the ton surface of the chamber between the first end of the inner tube and the outer tube.
