Abstract
The present invention relates to an ALD (Atomic layer deposition) apparatus and an ALD method. The ALD apparatus is provided with a reacting chamber and an annealing chamber, in which the reacting chamber is positioned with several heaters, a substrate to be deposited with an epitaxial layer may be transferred between different heaters, and each heater may independently moderate temperature. Different heaters correspond to different ALDs, and the number of the heaters may be varied to meet required a film to be deposited or composition of a crystal material. Because the heaters may be optimized to adapt to required temperature of different reactant gases, thickness of the epitaxial layer will meet expectation, and quality of the epitaxial layer will be promoted. Meanwhile, moderating the temperature independently may raise yield of production. Further, the ALD apparatus of the present invention introduces gas both horizontally and vertically to form a more even airflow field which benefits in forming a high-quality epitaxial layer.
