Abstract:
1. An evaporating apparatus that deposits a deposition material onto a treatment object, the evaporating apparatus comprising: a base disposed separately from the treatment object; a deposition source that evaporates the deposition material onto the treatment object, the deposition source placed on a surface of the base, the deposition source including a first outer region and a second outer region, the deposition material evaporating from the first and second outer regions; a first correction unit including a first correction plate located between the deposition source and the treatment object, the first correction plate covering the first outer region of the deposition source, the first correction plate having a first surface facing the deposition source, the first correction plate being capable of rotating about a rotation axis perpendicular to the first surface of the first correction plate, the rotation axis of the first correction plate positioned at a center of the first surface of the first correction plate so that there always exists a portion of the first outer region of the deposition source that is covered by the first correction plate while the deposition material is being evaporated from the deposition source; and a second correction unit including a second correction plate located between the deposition source and the treatment object, the second correction plate covering the second outer region of the deposition source, the second correction unit having a first surface facing the deposition source, the second correction plate being capable of rotating to control the thickness of a layer formed by the deposition material deposited on the treatment object.
