Abstract: PURPOSE: An apparatus for distributing temperature-variable gas is provided to control temperature of a whole area of a cover and an injection plate to which gas reaches for preventing gas reaction and liquefying of raw gas, so that thin films are formed with a uniform evaporation thickness at a high evaporation speed without pollution due to the generation of particles when evaporating the thin films on a water with a gas distributing device, thereby improving the reliability of semiconductor elements. CONSTITUTION: An apparatus for distributing temperature-variable gas includes a cover element(204) formed by welding upper and lower covers(204a,204b) to have a first channel(204c) between the covers, a second channel(204d) buried along an edge part of the upper cover, a first heater(EW1) mounted in the second channel, a supporting part(203) welded around the cover element, and a distributing plate(201) attached to a bottom surface of the supporting part, wherein a plurality of nozzles(201a) are formed in the distributing plate, a third channel(201c) is formed in the distributing plate, and second and third heaters(EW2,EW3) are mounted in the third channel.
