Abstract
The present disclosure relates to the field of display technology, particularly to a vacuum deposition apparatus and a vapor deposition method. The vacuum deposition apparatus includes a vacuum chamber and a rotary base, an evaporation source, and a plurality of vapor deposition zones arranged in series from bottom to top in the vacuum chamber, wherein the shape of the rotary base is a Reuleaux triangle, and the trajectories of movement of its vertices in the horizontal plane is a rounded square, the vapor deposition zones are arranged at intervals along the trajectories of movement of the vertices of the rotary base, the evaporation source is driven by the rotary base to pass below the vapor deposition zones sequentially, so that the evaporation source can be used to perform the vapor deposition operation in multiple directions simultaneously, thus improving the uniformity of film formation and utilization of the evaporation material.
