Abstract:
1. A vapor deposition device comprising: a base defining a through hole and a plurality of grooves in one surface thereof, the grooves being surrounding the through hole and configured for receiving precursors; a plurality of heating sources disposed in the grooves respectively for vaporizing the precursors into corresponding precursor gases; a hollow rod extending through the through hole and defining a plurality of vents along a circumference direction thereof, each of which points to an upper space of a corresponding groove, the hollow rod comprising an open end and an opposite closed end; a bracket connected to the closed end; a plurality of bearing seats fixed to the bracket for supporting a plurality of substrates to be coated, the substrates facing the grooves respectively; and an ion source coupled to the open end and configured for emitting ions; the hollow rod configured for guiding the ions to exit from the vents to the upper spaces of the corresponding grooves to ionize precursor gases ascending thereto.
