Definitions
- the present invention relates to a vapor deposition source for a vacuum vapor deposition apparatus which is disposed in a vacuum chamber and sublimates a sublimable material and deposits it on a deposition object.
- an organic EL element there is a process of depositing a sublimable material (organic material) such as an aluminum quinolinol complex (Alq 3 ) or an aromatic diamine on a deposition object such as a substrate in a vacuum atmosphere.
- a sublimable material such as an aluminum quinolinol complex (Alq 3 ) or an aromatic diamine
- a vapor deposition source used in such a vacuum vapor deposition apparatus is known from Patent Document 1, for example. This is provided with a crucible whose upper surface in the vertical direction is opened, and heating means such as an induction coil for heating the crucible (see the column of the prior art).
- the above-mentioned materials generally have poor thermal conductivity, and in addition, unlike materials that vaporize through the liquid phase, convection of the material in the crucible does not occur during heating. For this reason, when the crucible is filled with, for example, a powdered material in the conventional evaporation source and heated by a heating means in a vacuum atmosphere, the material is sublimated from the material in contact with the wall surface of the crucible that directly transfers heat. To go. At this time, from the upper layer portion of the filled material facing the upper surface opening of the crucible, the sublimated material scatters toward the deposition object through the upper surface opening of the crucible, but sublimates in the lower layer portion located below it.
- the resulting material collides with a relatively low temperature material (in other words, not yet heated to the sublimation temperature) existing around it, and returns to a solid.
- a relatively low temperature material in other words, not yet heated to the sublimation temperature
- the sublimated material is scattered only from a limited range, so that the amount of sublimation per unit time under the same pressure is small and the deposition rate for the deposition object is low (that is, the productivity is low). There's a problem.
- the present invention provides a vapor deposition source for a vacuum vapor deposition apparatus that can increase the amount of sublimation per unit time when depositing a sublimable material and has a high vapor deposition rate for a deposition object. That is the subject.
- a deposition source for a vacuum deposition apparatus which is disposed in a vacuum chamber and sublimates a sublimable material and deposits on a deposition target, is provided on the deposition target.

It sublimes from a material that is directly heated or a material that conducts heat directly from an inner container that is heated by radiant heat.

- the present invention most of the sublimated material is taken out to each through-hole, and it is suppressed as much as possible from colliding with a relatively low temperature material (that is, non-heated material) and returning to a solid. For this reason (in other words, the area where the sublimated material is scattered increases), the amount of sublimation increases dramatically compared to the conventional example in which the sublimated material is scattered only from a limited range.
- the deposition rate for the deposition object can be increased.
- the vapor deposition source for the vacuum vapor deposition apparatus of the present invention can obtain a high vapor deposition rate even at a low heating temperature, and is therefore optimal for vapor deposition of organic materials such as aluminum quinolinol complexes and aromatic diamines.

- the sublimated material In addition to the space (first space) between the inner wall of the crucible and the outer measurement wall of the inner container, the sublimated material also passes between the inner bottom wall of the crucible and the outer bottom wall of the inner container.
- the amount of sublimation can be further increased, which is advantageous.
- a certain gap that defines the space is formed only by installing the inner container.
- the inner container can be positioned concentrically in the crucible.
- a metal wire having a predetermined diameter is assembled in a grid shape like a metal mesh, or a circular or slit shape through which steam passes through a metal plate like a punching metal.

- the mesh size serving as a through hole that allows the sublimated material to communicate with each other in a diameter range of ⁇ 0.2 to 1.0 mm is # 10. It is preferable to be in the range of ⁇ 50.
- sublimation materials organic materials
- such as aluminum quinolinol complexes and aromatic diamines are generally cohesive even when filled with a powdery material, and almost leak out from each mesh. If the outer container is piled up without any problems, and if a part of the outer container is leaked, it is simply accumulated on the inner bottom wall of the outer container, and then sublimates when the outer container is heated.

It moves at speed. Since a well-known device can be used as the substrate transfer device 2, further description is omitted.
- a plate-like mask plate 3 is provided between the substrate Sw transported by the substrate transport device 2 and the vapor deposition source DS.
- the mask plate 3 is mounted integrally with the substrate Sw and is transported by the substrate transport device 2 together with the substrate Sw.
- the mask plate 3 can be fixedly disposed in advance in the vacuum chamber 1.

- the crucible 4 has a bottomed cylindrical contour with an open top in the vertical direction, and has a good thermal conductivity such as molybdenum, titanium, stainless steel, and carbon, and is formed of a high melting point material.
- the upper surface opening 41 of the crucible 4 constitutes a spout for the sublimated material in the present embodiment.
- a heating means Ht made of a known material such as a sheath heater or a lamp heater is provided.
- the cylindrical body 5 which comprises the inner container of this embodiment is inserted in the crucible 4.
- the cylindrical body 5 is made of a material having a high heat melting point such as molybdenum, titanium, and stainless steel, and in this embodiment, a metal mesh formed by assembling the wire 51 in a lattice shape has a bottom. It is formed so as to have a cylindrical outline, and each mesh 52 portion of the metal mesh constitutes the through hole of this embodiment.
- the wire diameter of the wire 51 is preferably in the range of ⁇ 0.2 to 1.0 mm, and the size of the mesh 52 is preferably in the range of # 10 to # 50. If the mesh (opening) 52 is too large, there is a problem that the material cannot be held. On the other hand, if the mesh 52 is too small, a problem occurs that the passage of the sublimated material is hindered.
- a plurality of rod-like leg pieces 54 are provided on the outer bottom wall 53 of the cylindrical body 5 with a space therebetween. Further, on the outer peripheral wall 55 of the cylindrical body 5 constituting the outer wall of the present embodiment, a bar-shaped spacer member 56 is spaced from the inner bottom wall 42 of the crucible 4 at the same height and in the circumferential direction. There are several standing.
- the cylindrical body 5 When the cylindrical body 5 is installed in the crucible 4 in the vacuum chamber 1 under atmospheric pressure, the cylindrical body 5 is inserted into the upper surface opening 41 of the crucible 4 from the leg piece 54 side, and each spacer member 56 is fixed to the main body. The cylindrical body 5 is moved downward while sliding along the inner peripheral surface 43 of the crucible 4 constituting the inner wall of the embodiment.
- a first space 6a consisting of a gap W1 corresponding to the length of the spacer member 56 is defined between the inner peripheral surface 43 of the crucible 4 and the outer peripheral wall 55 of the cylindrical body 5, in addition to this.
- a second space 6 b is defined between the inner bottom surface 42 of the crucible 4 and the outer bottom wall 53 of the cylindrical body 5, which is a gap W ⁇ b> 2 corresponding to the length of the spacer member 56.
- the length of the leg piece 54 and the spacer member 56 is such that when the crucible 4 is heated by the heating means Ht in a state where the vacuum chamber 1 is in a vacuum atmosphere, the first space can be efficiently heated by radiation from the crucible 4. 6a and the conductance of the second space 6b, so that the sublimated organic material can be efficiently guided from the respective mesh 52 of the metal mesh to the upper surface opening 41 of the crucible 4 through the first space 6a and the second space 6b. It is set in the range of 1 mm to 30 mm. After inserting the cylindrical body 5 into the crucible 4, the cylindrical body 5 is filled with a sublimable organic material 7.
- Examples of the organic material 7 used for vapor deposition with the vapor deposition source of the present embodiment include aluminum quinolinol complex (Alq 3 ) and aromatic diamine, and the powdered material is filled from the upper surface opening of the cylindrical body 5. It has become so. Thus, even if it fills the cylindrical body 5 with the powdery organic material 7, since these organic materials 7 are cohesive, they are piled up almost without leaking from each mesh
- the organic material 7 as described above generally has poor thermal conductivity, and in addition, unlike the material that vaporizes through the liquid phase, convection of the material in the crucible does not occur during heating. For this reason, when the organic material 7 is directly filled in the crucible Pc and deposited as in the conventional example, as shown in FIG. 2 (a), when the crucible Pc is heated by a heating means not shown, heat is directly transferred. The organic material 7 sublimates from the organic material 7 in contact with the wall surface of the crucible Pc. From the upper layer portion Pu of the filled organic material 7 facing the upper surface opening Po of the crucible Pc, the sublimated organic material 7a becomes the upper surface opening Po of the crucible Pc.
- the organic material 7b sublimated in the lower layer portion Pd located below the substrate (not shown) passes through the substrate 7 (not shown) and is heated to a relatively low temperature (in other words, still a sublimation temperature). It is collided with the organic material 7 and returns to solid. As a result, the sublimated organic material 7 is scattered only from a limited range, so that the amount of sublimation per unit time under the same pressure is small and the deposition rate for the deposition object is low.
- the vapor deposition source DS of this embodiment when the organic material 7 is deposited on the substrate Sw in a vacuum atmosphere, when the crucible 4 is heated by the heating means Ht, it is directly heated through each mesh 52 by the radiant heat from the crucible 4.
- the organic material 7 is sublimated from the organic material 7 and the organic material 7 that is directly transferred from the metal mesh wire 51 heated by radiant heat.
- the sublimated organic material 71 the upper layer portion of the filled organic material 7 directly passes through the upper surface opening 41 of the crucible 4, and the lower layer portion of the filled organic material 7 has the first space 6 a and the second space 6. Due to the conductance of the space 6b, the light is guided from the first space 6a and from the second space 6b to the upper surface opening 41 of the crucible 4 through the first space 6a, and scattered from the jet port toward the substrate Sw.
- the sublimated organic material 71 is taken out from each mesh 52 of the metal mesh, and can collide with a relatively low temperature material (that is, an unheated material) to return to a solid. Because it is suppressed as much as possible (in other words, because the area where the sublimated material is scattered increases), the sublimated material is scattered only from a limited range. The amount of sublimation increases, and the deposition rate for the deposition object can be increased. That is, as shown in FIG. 3, when the deposition rate with respect to the heating temperature of the crucible 4 and Pc is measured, the embodiment of the present invention indicated by the- ⁇ -line is compared with the conventional example indicated by the -O- line. In the case of a material, a deposition rate of 1.1 to 2 times can be obtained.
- the inner container has been described as an example in which a metal mesh is formed into a cylindrical shape.
- the inner container is not limited to this, and a circular or slit-shaped opening (The one formed with a cylindrical shape of the one having a through-hole) or the one formed by expanding the expanded metal into a cylindrical shape can be used, and on the other hand, the cylindrical body can be composed of porous ceramics, Moreover, a through hole is not necessarily required in the bottom wall of the inner container.
- the hole diameter of the through hole is not particularly limited as long as it allows the passage of the sublimated organic material, and the ratio of the total area of all the through holes to the outer surface area of the cylindrical body is determined by the deposition rate. It is set as appropriate in consideration.
- the crucible 4 which opened the upper surface as an outer container was demonstrated to the example, in order to adjust the conductance of the 1st space 6a and the 2nd space 6b, on the upper surface of the crucible 4 A lid provided with at least one injection nozzle may be attached.
- the outer container although not specifically illustrated and described, a container (so-called line source) in which injection nozzles are arranged on the upper surface of the storage box can be used.
