The present disclosure relates to the field of vapor deposition technologies, and discloses a vapor deposition method. The vapor deposition method includes: applying an exciting acoustic wave to the target, such that particles in a predetermined location of the target break away from the target and adhere to a predetermined region of the substrate when an energy of the particles is higher than an energy required for the particles to break away from the target. By using the vapor deposition method, losses of vapor deposition materials may be avoided, utilization of the vapor deposition materials may be increased, and thus costs may be reduced.
