Abstract
The present disclosure provides an evaporation device and an evaporation method using the evaporation device. The evaporation device includes a main chamber with an internal space and an evaporation mechanism under the main chamber. The evaporation mechanism includes at least two crucible accumulation chambers. The evaporation mechanism is configured to be operated in a first state where a first crucible accumulation chamber is at an evaporation position and in communication with the main chamber to form a vacuum space, and evaporation of a material in the crucible in the first crucible accumulation chamber is performed, and in a second state where, in a vacuum environment, the first crucible accumulation chamber is moved away from the evaporation position and a second crucible accumulation chamber is moved to the evaporation position and in communication with the main chamber.
