Specifically, the vapor deposition material is heated by an ion beam or an electron beam to change the vapor deposition material into a gaseous state or an ionic state, and is deposited on the surface to be plated to form a vapor deposition material film layer. The vapor deposition technique is widely used due to the short film formation process and easy control of the process, such as the surface reflective film layer of the optical element, the gold surface of the decorative part, and the silver film layer. Steaming, the process is carried out in a treatment device, which usually comprises an evaporation chamber and an evacuation system for providing the vacuum required for evaporation, and the evaporation chamber has a volume The enthalpy of the vapor deposition material, one and one are still opposite & When the evaporation material is heated and evaporated 2, the evaporated evaporation material particles are rushed to the workpiece to be plated with a certain energy and deposited on the surface of the workpiece to be emptied. Nothing in the pre-melting material or the coating process, when the electron beam or the ion bombardment material, 'the material often comes out (4), which leads to the material's low plasticity' and has a great influence on the cleanliness of the steaming chamber. Affect the quality of optical thinness. Reverse [Summary of the Invention] The following will be combined with the accompanying drawings. For further details of the embodiments of the present invention, and referring to FIG. 1 and FIG. 2, the vapor deposition apparatus 200925302 100 according to the embodiment of the present invention includes an evaporation chamber 1〇, _, an energy beam generating device for the material 30/ ,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, The mask 12 and the material of the crucible 11 may be selected from the group consisting of tungsten, molybdenum, lithium, gamma, and nitriding. The _;: ink opening = column shape, frustum shape, boat shape or other shapes can be: steaming surface receiving portion m and one at the top = 11 can be set - feeding port (not shown) to facilitate the two hanging Grass to achieve continuous evaporation operation. ^ 1 into the feed, if it is placed on one of the tops 112 of the (four) 11, and can be fixed by the right dry screw I, the bottom of the cover 12 has an opening 121 matching the opening 112 of the (four) u = portion, the cover β A plurality of airflow through holes m, the side wall of the mask 12 having an inlet portion having: an inlet (2) for heating the vapor-depositing material for the internal vapor deposition material; The mask 12 can also be selected from the group consisting of tungsten, gu, button, copper, graphite, oxidized, carbonized, and nitrided metal. The shape of the mask 12 may also be a column shape, a truncated cone shape, a boat shape or other polygonal shape, as long as the shape of the opening 121 at the bottom of the mask 12 matches the shape of the opening 112 of the top portion of the frame. Preferably, the shape of the 坩埚u is an inverted frustum shape, and the shape of the mask 12 is a cylindrical shape. The opening 112 at the top of the 坩埚J and the opening 121 at the bottom of the hood 12 are both circular. The mask 12 is sleeved on the opening 112 at the top of the 坩埚n, and the opening ΐ2 is opposite to the opening 112. At this time, outside the opening 121 The diameter is equivalent to the outer diameter of the opening 112, and 200925302 ensures that the mask 12 can be placed just over the crucible 11. The entrance 123 of the side wall of the mask 12 is located adjacent to the opening 121 at the bottom of the mask 12, and the inlet 123 communicates with the opening 121 at the bottom of the mask 12. The plurality of airflow through holes 122 are evenly arranged on the top plane of the mask 12. In this embodiment, the plurality of airflow through holes 122 are arranged in a row on the top circumferential surface of the mask 12 and are symmetrically arranged. This arrangement allows the concentration and spatial distribution of the vapor deposition material to be more uniform when it exits through the plurality of gas flow through holes 122. The plurality of airflow through holes 122 are the same size and may be in the shape of a β circle, a square, a diamond, a triangle or a polygon. The workpiece carrier 13 to be plated is disposed opposite the air outlet 112 of the crucible 11, and one or a plurality of workpieces 131 to be plated can be placed in the workpiece carrier 13 to be plated. Preferably, the workpiece carrier 13 to be plated can also be connected with a workpiece preheating device to be preheated to preheat the surface of the workpiece to be plated, to achieve a better evaporation effect, and a workpiece turning device to be automatically turned over. The workpiece is plated to achieve continuous evaporation.抽 The pumping system 20 is used to provide the vacuum required for vapor deposition of the vapor deposition chamber 10. The energy beam generating means 30 is for generating an energy beam which enters the crucible 11 through the inlet 123 of the side wall of the mask 12 and is incident on the vapor deposition material in the crucible 11. The vapor deposition material is heated and evaporated to a gaseous or ionic state, and the evaporated vapor deposition material particles are punched out through the plurality of gas flow through holes 122 at the top of the mask 12, and are rushed to the workpiece carrier 13 to be plated with a certain energy, and deposited on the workpiece. A surface of the workpiece 131 to be plated is formed to form a vapor deposition material film on the surface of the workpiece 131 to be plated. In this embodiment, the energy beam is generated 200925302, the device 30 is an electronic grab 3〇1, and the electron grabs 3〇1 to emit an electron beam, and the electron beam is concentrated by the steering magnetic field to the fault. Steamed mineral material. The electron beam is deflected by a steering magnetic field 3〇2 by an angle of 27 ,, so that the electron beam can be vertically struck on the steaming material to plate the material. Of course, the energy beam generating device 3 can be an electron beam generating device' or an ion beam generating device. That is, the energy beam generating device 3G is not limited to the above-described form in which electron beams are emitted by electrons, and an ion beam or other particle irradiation form or the like may be used.
