Abstract: Provided is a showerhead that can inject a reaction gas into a reaction chamber in a manner such that the injected reaction gas form a spiral vortex flow field. Therefore, the injected reaction gas can be mixed within a shorter distance, and thus the effective deposition radius of a wafer can be increased so that uniform-density deposition can be performed on the entire surface of the wafer using the mixed reaction gas.

Abstract: Provided is a chemical vapor deposition apparatus. The apparatus includes a reaction chamber, a gas introduction unit, and a gas exhaust unit. The reaction chamber includes a susceptor on which a wafer is loaded and a reaction furnace in which the wafer is processed by chemical vapor deposition. The gas introduction unit is disposed at an outer wall of the reaction chamber to supply reaction gas from an outside of the reaction furnace to a center portion of the reaction furnace. The gas exhaust unit is disposed at a center portion of the reaction chamber to discharge the reaction gas to an upper or lower outside of the reaction chamber after the reaction gas is used for a reaction in the reaction furnace. Therefore, the gas density inside the chamber can be kept at a substantially uniform state even when process pressure is increased for growing a high-temperature deposition layer.
