A source supplier includes a source reservoir that contains a liquefied source fluid for a supercritical process, a vaporizer that vaporizes the liquefied source fluid into a gaseous source fluid under high pressure, a purifier that removes organic impurities and moistures from the gaseous source fluid and an analyzer connected to the purifier that analyzes an impurity fraction and a moisture fraction in the gaseous source fluid. Moisture and organic impurities are removed from the source fluid to reduce the moisture concentration of the supercritical fluid in the supercritical process.

A wafer guide for preventing a wafer breakage in a semiconductor cleaning apparatus includes a lower supporter, side supporters, fixing units and stoppers. The lower supporter is provided with a plurality of slots formed with the same interval in a length direction to vertically stand a plurality of wafers thereon. The side supporters are structured and arranged in parallel at each side above the lower supporter. The side supporters support side end parts of the wafers. The fixing units are adapted to support both end parts of the lower supporter and the side supporters, and may be fixed to a bath. The stoppers are individually coupled to each of the fixing units. The stoppers are operable to generate an error in a close operation of holder units of the robot chuck when the robot chuck deviates from a normal alignment range, so as not to perform a wafer chucking, thereby preventing a wafer breakage during the wafer chucking.
