Abstract:
1. A reaction apparatus for atomic layer deposition (ALD), comprising: a vacuum chamber having a gas inlet, a gas outlet, and a gas flow path for connecting the gas inlet and the gas outlet; a reactor located in the vacuum chamber, including a reaction chamber where a first gas, which is input through the gas flow path, reacts with a specimen, which is located in the reaction chamber, the reactor further including a gas distributor, which is located in the reaction chamber to evenly supply the gas; a specimen location controller for moving the specimen located in the vacuum chamber to the reaction chamber; and an analyzer, which is connected to the reaction chamber, for analyzing a second gas generated in the reaction chambers, wherein the gas distributor comprises: a first annular gas distributor having a first vertical mesh inner wall for evenly supplying the first gas, which is input to the reaction chamber via the gas inlet, the first gas exiting the first vertical mesh inner wall in a horizontal direction: and a second annular gas distributor having a second vertical mesh inner wall, which is connected to an upper portion of the reaction chamber, for exhausting the second gas generated in the reaction chamber to the gas outlet in order to homogenize the second gas in the reaction chamber, the second gas entering the second vertical mesh inner wall in a horizontal direction.
