摘要:
Disclosed are a vaporization apparatus and a control method for the same. The vaporization apparatus includes a vaporization crucible adapted to receive a raw material; a vaporization heating unit adapted to vaporize the raw material by heating the vaporization crucible; a temperature measuring unit adapted to measure temperature of the vaporization crucible; a power measuring unit adapted to measure an applied power of the vaporization heating unit; and a control unit adapted to control a vaporization quantity of the raw material based on any one of a temperature variation value of the temperature measuring unit and a power variation value of the power measuring unit. The vaporization apparatus uses a non-contact/electronic method which measures a vaporization quantity through a temperature variation value and a power variation value during vaporization of a raw material. Therefore, since, differently from a contact method, a vaporization quantity measuring unit does not directly contact a raw material gas, various raw materials can be supplied and large quantity raw material supply or long time raw material supply can be achieved without deterioration of the function. In addition, preciseness of the raw material supply may be enhanced since the electronic method is capable of precise measurement of the vaporization quantity.

Disclosed is a vacuum deposition apparatus, which comprises: a chamber mounted with a source for jetting an application material in the gaseous state for deposition onto a substrate; heaters formed to the inner wall of the chamber and internal parts; a pump for aspirating air out of the chamber; and a plurality of cold traps interposed between the chamber and the pump for cooling the air aspirated by the pump to remove the application material from the air. According to the vacuum deposition apparatus, it is possible to prevent direct damage to the internal parts or the inner wall of the chamber by application materials accumulated thereon. Additionally, the plurality of cold traps prevent pollution and stoppage in continuous production which allows substitution to be carried out without stoppage. Therefore, productivity may be improved compared to other equipment with similar specifications.

Provided are a source supplying unit and a method for supplying a source. The source supplying unit includes a pot configured to store a source material, an injector communicating with the pot to inject the source material evaporated from the pot, a high frequency coil part surrounding an outside of the pot, and a resistance-type heating part disposed at an outside of the injector. Since a high frequency induction heating method and a resistance-type heating method are combined to evaporate a source material to be supplied, a large amount of source material can be used, and the thickness and quality of a thin film can be easily controlled.
