Abstract:
1. A method for manufacturing a semiconductor device comprising the steps of: placing a substrate above a crucible in a treater, wherein the crucible contains a raw material; heating and sublimating the raw material to deposit an organic semiconductor over the substrate in the treater while introducing a first gas from below the crucible and the substrate; removing the substrate from the treater after depositing the organic semiconductor; and introducing a second gas into the treater and exhausting the second gas while heating the treater so that temperature in an inside of the treater is higher than a sublimation temperature of the organic semiconductor after removing the substrate from the treater, wherein the treater includes an outer tube and an inner tube, wherein the outer tube includes a curved top surface, wherein a top end portion of the inner tube is curved along the curved top surface of the outer tube, and wherein the inner tube has an opening at a top portion thereof to flow the first gas and the second gas between the outer tube and the inner tube.
