  However, the present invention is not limited to the embodiments described below, and can be realized in various different forms. These embodiments merely complete the disclosure of the present invention and have ordinary knowledge. It is provided to fully inform those skilled in the art of the scope of the invention.

  FIG. 1 is a schematic configuration diagram illustrating a substrate processing system in which a substrate processing apparatus according to the present invention is used, and FIG. 2 is a schematic cross-sectional view illustrating the substrate processing apparatus according to the present invention.

  As shown in the figure, the substrate processing system will be described on the assumption that it is an in-line method capable of processing a large number of substrates 10 quickly. The substrate processing system includes a carry-in unit 1000 into which a substrate 10 to be processed is carried in, a carry-out unit 5000 that is located away from the carry-in unit 1000 and carries out a processed substrate 10, and a carry-in unit 1000 and a carry-out unit 1000. And a plurality of substrate processing units 3000a to 3000c that are disposed inline with the unit 5000 and process the substrate 10. In addition, the substrate processing system includes a processing preparation unit 2000 that places the substrates 10 placed at the tips of the plurality of substrate processing units 3000a to 3000c and loaded into the substrate processing units 3000a to 3000c on the substrate holder 200 for alignment. The unloading preparation unit 4000 is further provided for removing the substrate 10 from the substrate holder 200 in order to unload the processed substrate 10 disposed at the ends of the substrate processing units 3000a to 3000c to the unloading unit 5000.

  The carry-in unit 1000 is a space where a large number of substrates 10 on which an organic thin film is deposited is placed at an end portion on one side of the substrate processing system, and a large number of substrates 10 are placed in the carry-in unit 1000. A mounted substrate cassette is arranged, and a buffer stage on which the substrate 10 taken out from the cassette stands by for the vapor deposition process is arranged.

  The substrate processing units 3000a to 3000c are spaces that are interposed between the carry-in unit 1000 and the carry-out unit 5000 to deposit an organic thin film, and include a chamber 400 in which at least one reaction space is provided, At least one or more organic raw material supply unit 100 provided corresponding to the reaction space in the chamber 400, and a substrate that is provided so as to be conveyed opposite to the organic raw material supply unit 100 and supports and conveys the substrate 10 A holder 200. In addition, when the single substrate processing units 3000a to 3000c are disposed and the single organic raw material supply unit 100 is disposed, a separate transport rail for transporting the substrate holder 200 is not necessary. However, when a large number of substrate processing units 3000 a to 3000 c are disposed and a large number of organic raw material supply units 100 are disposed, the substrate 10 is arranged along the transport rail 300 in order to face the respective organic raw material supply units 100. Are preferably conveyed. Of course, the method for transporting the substrate holder 200 is not limited to the method using the transport rail, and various transport methods can be adopted as long as they are used by those skilled in the art.

  The chamber 400 is arranged so as to have one or a plurality of reaction spaces. Although not shown, the chamber 400 is provided with a gate through which the substrate 10 and the substrate holder 200 enter and exit, and the chamber 400 is evacuated or exhausted to exhaust unreacted gas and the like inside the chamber 400. A line is formed.

  As the substrate holder 200, any type of holder can be used as long as the substrate 10 is transported while being supported horizontally or vertically. The present invention proposes a holder that holds the periphery of the substrate 10 and supports it vertically. At this time, the substrate holder 200 is transported while being supported and guided by the transport rail 300 provided in the chamber 400.

  Further, an organic material supply unit 100 that supplies an organic material to be deposited on the substrate 10 is disposed at a position facing the substrate holder 200.

  FIG. 3 is a schematic cross-sectional view showing a vapor deposition material supply apparatus according to the present invention. As shown in the figure, the organic raw material supply unit 100 includes a crucible 110 in which a storage space 110a in which a raw material is filled and a vaporization space 110b in which the raw material is vaporized are linearly connected, The material unit filled in the crucible 110 is transported continuously or periodically from the storage space 110a to the vaporization space 110b, and disposed outside the vaporization space 110b formed in the crucible 110, and the vaporization. A heat generating unit 130 that supplies heat for vaporizing the raw material to the space 110b, and a thermal change of the raw material that is disposed outside the storage space 110a formed in the crucible 110 and stored in the storage space 110a is prevented. The cooling unit 140 and one side are connected to the vaporization space 110b side of the crucible 110 to form a flow path through which the vaporized source material flows. Comprises a communication pipe 150, the injector 160 raw material is injected is contacted to the other side of the vaporization already said communication pipe 150.

  The present invention presents an apparatus for manufacturing an organic light emitting device (OLED), and it is preferable that, for example, an organic material is used as a raw material in the present invention.

  The crucible 110 is formed in a cylindrical tube having one side opened. At this time, in the crucible 110, a storage space 110a filled with the source material is formed on the lower side, and a vaporization space 110b in which the source material is vaporized is formed on the upper side. The storage space 110a and the vaporization space 110b are not spaces provided by predetermined installation means but are spaces partitioned according to the state of the raw material. For this reason, a space in which the source material exists in a solid phase or a liquid phase is defined as a storage space 110a, and a space in which the solid or liquid phase source material is vaporized by heat is defined as a vaporization space 110b. At this time, although not shown, the crucible 110 may be connected to a vacuum line for maintaining the inside of the crucible 110 in an ultra-vacuum pressure environment during the vapor deposition process.

  The transport unit 120 is a means for gradually transporting the raw material filled in the storage space 110a of the crucible 110 to the vaporization space 110b. The head 121 is disposed inside the crucible 110 and pumps the raw material, The rod 122 is connected to the head 121, the other side is disposed outside the crucible 110 and moved together with the head 121, and the other side of the rod 122 is connected to the rod 122. And a drive unit to be moved.

  As the drive unit, any one that can move the rod 122 up and down, such as a motor 123 or a hydraulic cylinder, can be used. The present invention employs a motor 123 as a drive unit according to a preferred embodiment. More specifically, the transport unit 120 includes a motor 123 driven by a power source, a ball screw 124 rotated by the motor 123, and a lifting body that moves up and down by the rotation of the ball screw 124 on the ball screw 124. 125, and a support 126 that supports the rod 122 on the other side, the other side being fixed to the lift 125 so as to be moved integrally with the lift 125. For this reason, when the ball screw 124 is rotated by the rotation of the motor 123 and the elevating body 125 moves up and down, the support body 126 is moved integrally with the elevating body 125 and the rod 122 is moved up and down. As a result, the head 121 disposed at the upper end of the rod 122 conveys the source material from the storage space 110a of the crucible 110 to the vaporization space 110b.

  The heat generating unit 130 is a means for supplying thermal energy for heating and vaporizing the raw material conveyed from the storage space 110a of the crucible 110 to the vaporizing space 110b, and is capable of supplying thermal energy for vaporizing the raw material. Anything can be used. For example, a core heater or a lamp heater can be used as the heating unit 130, and in this embodiment, a core heater is used. The heat generating unit 130 is formed by winding a resistance heating wire 131 around the outer peripheral surface of the crucible 110 where the vaporization space is formed. At this time, Ta, W, Mo metal, or alloy wires thereof can be used as the resistance heating wire 131.

  Further, in order to facilitate the heating of the source material by the heat generating unit 130, a metal sheet 111 having high thermal conductivity is disposed on the inner wall of the crucible 110 where the vaporization space 110b is formed. It may be. At this time, the metal sheet 111 is preferably formed in a donut shape or a pipe shape.

  The cooling unit 140 is means for preventing the raw material filled in the storage space 110a of the crucible 110 from being altered by the heat of the heat generating unit 130, and cools the storage space 110a in which the raw material is stored. Anything can be used. For example, in the present embodiment, a cooling jacket is used as the cooling unit 140. The cooling unit 140 is disposed so as to surround a portion of the outer peripheral surface of the crucible 110 where the storage space 110a is formed, preferably a portion adjacent to the portion where the heat generating unit 130 is disposed. The cooling unit 140 is formed by surrounding a cooling flow path 141 through which cooling water flows on the outer peripheral surface of the crucible 110 where the storage space 110a is formed.

  Further, a connecting pipe 150 is connected to the upper part of the crucible 110 to flow the source gas vaporized by the heat generating unit 130 to the injector 160.

  The communication tube 150 may be bent into a predetermined shape so as to be able to communicate with the injector 160. In addition, a heat generation line 151 is disposed on the outer peripheral portion of the communication tube 150 in order to prevent the vaporized source gas from further changing into a liquid phase or a solid phase.

  At this time, the diameter and length of the connecting pipe 150 adversely affects the denaturation of the raw material. More specifically, the denaturation of the source material occurs due to the high temperature and pressure in the crucible 110. For this reason, in order to prevent denaturation of the raw material, it is necessary to keep the temperature and pressure in the crucible 110 low. In addition, since the vaporization temperature of the raw material is affected by the degree of vacuum and the vaporization temperature tends to decrease as the degree of vacuum decreases, it is better to keep the degree of vacuum in the crucible 110 low in order to prevent denaturation of the raw material. More efficient.

  The degree of vacuum in the crucible 110 can be interpreted as a concept of conductance, and the conductance is greatly influenced by the length and diameter of the pipe. Equation 1 below is an equation for calculating conductance.

[Formula 1]
C = 3.81 (T / M) ^1/2 D ³ /(L+1.33D)
D: Diameter of piping L: Length of piping T: Temperature M: Molecular weight of raw material

  As apparent from the above equation 1, the conductance tends to increase as the length of the pipe is shorter and the diameter is larger. For this reason, in this embodiment, in order to reduce the degree of vacuum in the crucible 110 and prevent alteration of the raw material, the length of the connecting tube 150 is made as short as possible and the diameter of the connecting tube 150 is increased. Is preferred. In particular, since the conductance value greatly depends on the diameter of the connecting tube 150 rather than the length of the connecting tube 150, in this embodiment, in consideration of the organic material used as the raw material and the temperature in the crucible 110, The diameter of the connecting pipe 150 is 20 to 200 mm. This is because if the diameter of the connecting pipe 150 is 20 mm or less, the conductance is too low to obtain an effect of preventing the raw material from being altered so much, whereas if the diameter of the connecting pipe 150 is 200 mm or more, This is because compatibility with other devices is limited. In particular, the diameter of the connecting pipe 150 is preferably 70 mm in consideration of the efficiency of preventing deterioration of the raw material and compatibility with other devices.

  Further, an engagement member 170 is connected to one side of the communication pipe 150, and a thread is formed on the engagement member 170 and is screwed to the upper end of the crucible 110. At this time, the storage space 110a, the vaporization space 110b, the inside of the engaging member 170, and the inside of the connecting pipe 150 of the crucible 110 are communicated. By engaging the engagement member 170 and the crucible 110 in this manner, the engagement member 170 and the crucible 110 can be easily attached and detached. Thereby, when filling the raw material, after removing the engaging member 170 from the crucible 110, the raw material can be easily filled into the storage space 110a of the crucible 110.

  Further, an injector 160 is connected to the other side of the communication pipe 150.

  The injector 160 has a flow path communicating with the communication pipe 150 therein, and a gas injection port 161 through which the vaporized raw material is injected at an end thereof. At this time, the injector 160 has a linear shape, and the gas injection ports 161 are arranged in a straight line so as to face the substrate 10. An exothermic line 162 is also provided at the outer periphery of the injector 160 in order to prevent the vaporized raw material from further changing into a liquid phase or a solid phase.

  The injector 160 affects the degree of vacuum of the crucible 110 by communicating with the communication pipe 150. For this reason, it is preferable to set the diameter of the injector 160 to 20 to 200 mm, and more preferable to set the diameter of the injector 160 to 70 mm so as to correspond to the connecting pipe 150, for the same reason as that for limiting the diameter of the connecting pipe 150. . In addition, it is preferable to form the diameter of the gas injection port 161 of the injector 160 larger than 8 mm.

  Since the crucible 110, the transport unit 120 and the injector 160 are disposed in the chamber 400, they are integrally supported by a support unit 180. In addition, the support unit 180 is disposed on a rail 185 provided so that the injector 160 is transported toward the substrate 10 in order to adjust the distance between the injector 160 and the substrate 10.

  The support unit 180 supports the movable body 181 moved along the rail 185, a support frame 182 fixed to the movable body 181 and integrally supporting the crucible 110 and the transport unit 120, and the injector 160. And a support plate 183. Of course, the shapes of the movable body 181, the support frame 182, and the support plate 183 are not limited, and any shape and structure that integrally supports the crucible 110, the transport unit 120, and the injector 160 can be adopted. is there. The movable body 181 may be anything as long as it can move on the rail 185. For example, a driving method using a ball screw, a driving method using an LM guide, or the like can be applied.

  Further, an injection amount measurement sensor 184 that measures the injection amount of the vaporized raw material from the injector 160 is disposed in front of the injector 160. Therefore, according to the injection amount of the raw material measured by the injection amount measuring sensor 184, the amount of the raw material vaporized by controlling the heating temperature of the heating unit 130 and the moving speed of the head 121 of the transport unit 120 is determined. Adjust.

  Furthermore, a shutter 190 that selectively restricts the flow of the raw material injected from the injector 160 is interposed in front of the injector 160, preferably between the injector 160 and the substrate holder 200. The shutter 190 is manufactured in a shape having a surface closing the front of the gas injection port 161 formed in the injector 160, and operates by a rotation method or a sliding method. In the present embodiment, a method is proposed in which the shutter 190 is rotated by driving the motor 191 to selectively open and close the front of the injector 160. Of course, the shape and operation method of the shutter 190 are not limited to the above embodiment, and any shutter can be used as long as it can selectively restrict the flow of the raw material injected from the injector 160 onto the substrate 10. It can be adopted.

  Furthermore, as shown in FIG. 1, the unloading unit 5000 is placed on the other end of the substrate processing system and waits for the large number of substrates 10 on which the organic thin film is deposited to be unloaded. An unloader is disposed in the carry-out unit 5000, and the unloader loads a large number of vapor-deposited substrates 10 on a substrate cassette and takes them out.

  The operation state of the substrate processing system to which the vapor deposition material supply apparatus and the substrate processing apparatus according to the present invention having such a configuration are applied will be described.

  4 and 5 are cross-sectional views showing the usage state of the vapor deposition material supply apparatus according to the present invention.

  First, as shown in FIG. 4, after removing the crucible 110 of the vapor deposition material supply device from the engaging member 170, a storage material 110 a inside thereof is filled with a raw material material to be vapor deposited on the substrate 10, that is, an organic material. Then, the crucible 110 and the engaging member 170 are engaged. Here, when many kinds of organic thin films are sequentially stacked, a plurality of substrate processing units 3000a to 3000c are formed correspondingly, and the organic material supply unit 100 is arranged in each of the substrate processing units 3000a to 3000c. After the installation, the crucible 110 is filled with an organic material to be deposited. At this time, the storage space 110a of the crucible 110 is filled with a sufficient amount of an organic substance capable of performing the organic thin film deposition process continuously or periodically. The organic material filled in the storage space 110a can be stored for a long time without being altered by the cooling of the cooling unit 140. It should be noted that the movable body 181 to which the crucible 110 and the injector 160 are fixed is moved to set an interval between the substrate 10 to be processed and the injector 160.

  When the organic raw material supply unit 100 is thus prepared, the substrate 10 prepared in the carry-in unit 1000 is carried into the processing preparation unit 2000, and the substrate 10 is placed on the substrate holder 200 and aligned. The substrate 10 thus prepared is transported by the substrate holder 200 and placed at a position facing the organic material supply unit 100 disposed in each of the substrate processing units 3000a to 3000c.

  When the substrate 10 is transported and placed in front of the organic raw material supply unit 100, preferably in front of the injector 160, the transport unit 120 of the organic raw material supply unit 100 operates to store the crucible 110 as shown in FIG. The organic material filled in the space 110a is transported to the vaporization space 110b. More specifically, as the motor 123 operates and rotates, the ball screw 124 rotates and the elevating body 125 moves up and down. Then, the rod 122 is moved up and down while the support 126 is moved integrally with the elevating body 125, whereby the head 121 disposed at the upper end of the rod 122 moves the raw material from the storage space 110 a of the crucible 110 to the vaporization space 110 b. To transport. Then, the organic substance is vaporized by heating the heat generating unit 130 provided around the vaporization space 110b. At this time, the amount of the organic substance to be vaporized is determined by controlling the heating temperature of the heat generating unit 130 and controlling the transport speed of the head 121 of the transport unit 120. And the organic substance stored in the storage space 110a without reaching the vaporization space 110b is prevented from being altered by cooling of the cooling unit provided around the storage space 110a.

  Thus, the organic substance vaporized by a desired amount in the vaporization space 110b is injected to the outside of the injector 160 through the engagement member 170 and the communication pipe 150 and through the gas injection port 161 formed in the injector 160. Further, by operating the shutter 190 and opening the shutter 190, the organic substance is smoothly ejected. The injected organic material is deposited on the substrate 10 to form an organic thin film on the substrate 10. At this time, the injection amount measurement sensor 184 disposed in front of the injector 160 measures the injection amount of the organic substance from the injector 160, and calculates the measurement amount to calculate the heating temperature of the heat generating unit 130 and the head 121 of the transport unit 120. To control the transport speed.

  If the transport of the substrate 10 is a continuous process, the shutter 190 disposed in front of the injector 160 is always kept open, whereas the transport of the substrate 10 is discontinuous. That is, if the process is performed periodically, it is preferable to operate the shutter 190 so as to be selectively opened or closed.

  When the vapor deposition of the single-layer or multilayer organic thin film is completed through the desired processing unit among the substrate processing units 3000a to 3000c in this way, the substrate 10 is transported to the unloading preparation unit 4000 and removed from the substrate holder 200. The removed substrate 10 is unloaded to the unloading unit 5000, and the multiple unloaded substrates are mounted on a cassette and taken out of the substrate processing system.

  As described above, the substrate processing system according to the present invention has been described on the assumption that it is an in-line method capable of processing a large number of substrates quickly. However, the present invention is not limited to this, and an organic thin film can be deposited. As long as it is, it can be applied to various types of processing systems. In the present invention, the organic thin film is deposited after the substrate and the injector are arranged perpendicular to the ground, and the substrate holder and the organic raw material supply are provided in order to arrange the substrate and the injector parallel to the ground. The portions may be arranged in the horizontal direction. As mentioned above, although this invention was demonstrated based on attached drawing and the suitable embodiment mentioned above, this invention is not limited to this, It is limited by the claim which is mentioned later. Therefore, those who have ordinary knowledge in this technical field can variously modify and modify the present invention without departing from the technical idea of the claims to be described later.
