  • Patent number: 10741765
    Abstract: A vapor deposition apparatus is configured to attract a vapor deposition mask by an electromagnet. The electromagnet includes a first electromagnet for generating a magnetic field in a first orientation, and a second electromagnet for generating a magnetic field in a second orientation, which is a reverse orientation to the first orientation. As a result, a generated magnetic field is weakened by operating the first and second electromagnets at the same time when a current is turned on, and an intended magnetic field can be obtained by thereafter turning off the second electromagnet. As a result, an influence of electromagnetic induction is reduced, reducing failure of elements and the like formed on a substrate for vapor deposition and degradation in properties of the elements. Meanwhile, by turning off the operation of the second electromagnet after the current is turned on, a normal attraction force can be obtained.
