Description of the invention (i) [Background of the invention] The present invention relates to the formation of a resist film on the surface of a substrate such as a glass substrate for a liquid crystal display (LCD) or a semiconductor wafer, and then a portion of the resist is removed. Membrane, processing device for processing such as drying, and processing method thereof. For example, when manufacturing L CD, a photoresist (photoresist) liquid is applied to a rectangular LCD substrate made of glass to form a resist film, and the anti-corrosive agent is exposed in accordance with the circuit pattern. The so-called photolithography (also known as photolithography) is used to develop a film and develop it to form a predetermined pattern. The formation of such a circuit pattern is carried out by using a resist coating and developing system using a plurality of processing units. In such a system, first, the substrate is subjected to surface modification by irradiating ultraviolet rays as needed, and the substrate is cleaned. Then, the cleaning unit performs brush cleaning and ultrasonic water cleaning. Then, in order to improve the stability of the resist, the substrate is subjected to a hydrophobic treatment (HMDS treatment) in the adhesion processing unit, and then the resist is applied in the resist coating processing unit. For the substrate on which the resist film is formed in this way, the pre-baking process performed by the heating unit and the pattern not exposed by the exposure device are sequentially performed, the development process is performed in the development processing unit, and the drying process is performed after the heating unit. To form a predetermined circuit pattern on the substrate. The processing from the application of the resist until the pre-baking will be explained in detail. First, hold the substrate that has been subjected to the degreasing treatment to a rotating chuck that can be rotated horizontally, and after supplying the resist from the top, rotate it (please read the precautions on the back before filling this page). Order the intellectual property of the Ministry of Economic Affairs The paper size printed by the Bureau ’s Consumer Cooperatives applies the Chinese National Standard (CNS) A4 specification (210X297 mm) -4- 504844 A7 B7 V. Description of the invention (2) (Please read the precautions on the back before filling this page) Substrate , The resist is diffused by centrifugal force to form a film on the substrate. When the resist is applied in this way, the thickness of the resist film immediately after coating is uniform, but after stopping rotation, no centrifugal force is generated, or with the passage of time, it will be affected by the surface tension. The resist is raised and thickened at the edge of the substrate. In the case of coating by such a rotation method, the removed resist will be wound around the substrate and adhere to it. Films of uneven thickness formed on the periphery (edge) of the substrate or resists adhered to the back surface may cause particles to be generated during subsequent substrate transportation, and may also be used to contaminate the substrate. The reason for this is that, traditionally (in the past), the removal (removal) of these resists was carried out by discharging the processing liquid such as thinner at a predetermined position, and then the substrate was transported to a pre-baking process. [Summary of Invention] Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs when using the above-mentioned process from forming a resist (resin) film to erasing (removing) the resist on the periphery and back of the substrate before pre-baking When the substrate is subjected to a pre-baking process or the like, or when the substrate is exposed and subjected to a development process. The contact marks with the fixing pins for supporting the substrate or the lifting pins for raising and lowering the substrate may be transferred (copied) to the substrate during heat treatment such as pre-baking treatment. In addition, the processing liquid such as thinner is discharged and supplied. In the past, this was performed using a nozzle mechanism that can move along the periphery (edge) of the substrate. However, in this state, it takes time to scan the nozzle. The processing time of each substrate will become long. As a result, it has the time required to include other processes. -5- This paper size applies the Chinese National Standard (CNS) A4 specification (210X297 mm). 504844 A7 B7 5. Description of the invention (3) Time (Tact time) will become a long time problem. (Please read the notes on the back before filling out this page) The present invention was invented in view of the above circumstances. The purpose is to provide a processing device and a processing method capable of preventing the transfer time and shrinkable production tact time of a substrate. In order to solve the above-mentioned problem, the applicant of this case has disclosed in a Japanese Patent Japanese Patent Application No. 10-233599, the same as No. 10-369306, a resist coating processing unit arranged in a row to apply a resist to a substrate, and a vacuum A vacuum drying unit for drying a substrate on which a resist (resist) film has been formed, and a processing device for a peripheral anti-feedback agent removing unit for removing a resist from a peripheral portion of the substrate after the vacuum drying. However, when the anti-repellent coating processing unit, the vacuum drying unit, and the peripheral resist erasing unit are separately provided in such a structure, the space occupied by each unit will become wide, which causes a problem that the device becomes large. As for the peripheral resist erasing unit, since the type of the scanning nozzle is used, it is expected to shorten the production cycle time. Printed by the Consumers' Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs. In addition to the aforementioned problems, the present invention also has to solve such new problems. The first invention is to provide a device for processing a substrate coated with a resist. The method is as follows: in a state where the substrate on which the resist (resist) film is formed is maintained at a predetermined position, the substrate is vacuum-dried and the resist on the periphery (edge) of the substrate is removed. The second invention is to provide a processing device for applying a resist to a substrate and subjecting the formed resist film to a drying treatment before heating treatment, which is characterized in that: Anti-corrosive coating processing unit, substrates with a resist film to be vacuum-dried, and standard paper sizes to be applied (CNS) A4iUM 210X297 mm) I " " 504844 A7 B7 V. Description of the Invention (4) The vacuum drying / peripheral resist erasing unit for removing the resist in the peripheral portion of the substrate. (Please read the precautions on the back before filling this page.) The third invention is to provide a processing device for a substrate coated with a resist, which is characterized by: A processing chamber; a degassing mechanism for decompressing the interior of the chamber; and a peripheral resist erasure mechanism for erasing (removing) the resist on the periphery of the substrate in the chamber. The fourth invention is to provide a processing device, which is characterized by including a resist coating processing unit to apply a uranium-resistant agent to a substrate, and a post-processing processing unit for the substrate after the uranium-resistant agent is applied. The post-processing unit includes: a (processing) chamber on which a substrate is to be placed; an exhaust mechanism to decompress the interior of the chamber; and a peripheral edge of the resist to wipe out the peripheral portion of the substrate in the interior of the chamber. Resist erasure mechanism. Printed on the consumer device of the Intellectual Property Bureau of the Ministry of Economic Affairs in the processing device of the present invention, the substrate is transported to the subsequent heat treatment process after the formed resist film is dried to an appropriate state, so that the generation of the substrate can be suppressed. Transfer to a resist film. In addition, the vacuum drying and erasing of the peripheral (edge) edge resist can be performed in the same space without moving the substrate, so that the device can be miniaturized. Furthermore, in such a processing device, it is also very desirable to be able to simultaneously perform resist removal on the entire periphery of the substrate. Therefore, the production cycle can be shortened, and the productivity can be improved. As a substrate processing method using such a processing device, according to the present invention, a processing method of a substrate coated with an anti-contact agent is provided, which is characterized in that after the aforementioned substrate is placed in a predetermined position in a (processing) room, Decompress the aforementioned room into a low-vacuum environment and maintain it for a predetermined period of time, and then maintain this paper standard to apply Chinese National Standard (CNS) A4 specifications (210X29 * 7 mm) 504844 A7 B7 V. Description of the invention (5) The aforementioned decompressed environment or Restore to atmospheric (pressure) environment to wipe out the anti-rust agent on the periphery of the substrate. (Please read the precautions on the back before filling out this page.) When using such a treatment method, it is possible to effectively prevent the transfer to the substrate. Furthermore, Japanese Patent Laid-Open No. 3-1 0 1 8 6 6 discloses a spinner for liquid coating, a vacuum drying device, and a spinner for cleaning the back surface of objects to be processed, which are sequentially arranged. Film formation device. However, in the same publication, there is no description of the removal of the film on the peripheral portion of the non-treated object, and there is no record of preventing the film from being dried or dried after the transfer of the film or the back surface is cleaned. In addition, the film forming apparatus described in the same publication requires space for each of the three types of devices such as a rotator. Therefore, there is a problem that the internal device becomes larger.

Description of the Invention (9) Brushing and washing are performed in the cleaning unit (SCR), and after any one of the heat treatment units (ΗP) in the treatment group 26 is heated and dried (dried), it is processed. Any of the cooling units (C 0 L) of group 2 7 are cooled. Then, the substrate G is transferred to the middle section 2a. In order to improve the fixation of the resist, the upper layer of the adhesion processing unit (AD) is subjected to a hydration treatment (HMDS treatment) and cooled in the lower cooling unit (COL). After that, a resist is applied to the anti-corrosive coating processing unit (CT) 2 2, and then the vacuum drying of the resist film under a low vacuum degree is sequentially performed on the VU / ER unit 2 3. The resist on the periphery (edge) of the substrate G and the resist attached to the back surface of the substrate G (hereinafter, this process will be referred to as "remaining periphery"), and the resist film is subjected to high vacuum Vacuum dry. In addition, the term "elimination peripheral edge" refers to a method including erasing a resist on the periphery (peripheral edge portion) of the surface on which the uranium-resistant film is formed on the substrate G, and removing the resist adhered to the side surface of the substrate G and the back surface of the substrate G. deal with. Thereafter, the substrate G is subjected to a pre-baking process in one of the heating units (HP) in the middle section 2b, and is cooled in the lower cooling unit (COL) in the processing group 29 or 30. Next, the substrate G is transferred from the relay section 16 to the exposure device by the main transfer device 19 and the transfer section 3, and is exposed to a predetermined pattern there. Then, the substrate G is carried into the processing section 2 by the transfer section 3 again, and if necessary, the heating processing unit (HP) of any of the processing groups 3 1, 32, and 33 in the rear section is subjected to post-exposure drying After processing, development processing is performed in any of the development processing units (DEV) 24a, 24b, 2 4c to form a predetermined circuit pattern. The developed substrate G will be in any one of the heat treatment sheets in the second section 2c (please read the precautions on the back before filling this page).

Description of the invention (10) Yuan (HP) After the post-drying treatment, it is cooled in any cooling unit (C0L), And the main transport device 19, 18, 17 and the transport (please read the precautions on the back before filling this page) transport mechanism 10 to accommodate the predetermined cassette on the cassette station 1. Next, a V U / E R unit according to an embodiment of the present invention will be described in detail. Fig. 2 is a cross-sectional view showing a configuration of the VU / ER unit 23, VA / ER unit 23A. On the VU / ER unit 2 3 A, the upper chamber (lid) 4 1 which is set to rise and fall freely is lowered from above to the fixed lower chamber 4 2, and the upper and lower chambers 41 and 41 are tightly adhered by the sealing material 4 8. 42, can be formed as a processing chamber 91. Printed in the lower room 4 2 by the Consumers' Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs. The table 4 5 is equipped with a substrate G and a lifting mechanism 4 4 (only the lifting rod is shown) is arranged to lift freely. A nozzle 50 for back washing is arranged at the lower periphery. The rear cleaning nozzle 50 has a hole 8 8 formed therein, and the processing liquid supply pipe 8 7 is arranged to communicate with the hole 8 8 ′ so that the processing liquid can be opened from the upper end of the hole 8 8. position. That is, the "backside cleaning nozzle 50" is used for erasing the resist on the back surface of the substrate G mainly when the peripheral edge is erased. The bottom wall of the lower chamber 4 2 is provided with a first exhaust port 4 3 'and the side wall is provided with a second exhaust port 4 6. The first exhaust port 4 3 is mainly responsible for exhausting the treatment chamber 91. However, when the peripheral edge is removed, a part of the processing liquid such as a thinner is discharged. The second exhaust port 4 6 is mainly provided for the purpose of discharging the treatment liquid at the time of removing the peripheral edge ', but also has the function of an exhaust treatment chamber 91. The second exhaust port 46 is ideally set to be approximately the same as the substrate. The paper size applies the Chinese National Standard (CNS) Λ4 specification (210X297 mm) _ 13_ 504844 A7 ___B7_ V. Description of the invention (Μ) A high-level position, That is, the periphery of the outer periphery (edge) of the substrate G may be disposed not in the lower chamber 4 2 but in the upper chamber 41. The upper chamber 41 is, as shown in the plan view of FIG. 3, a peripheral edge remover 49, which is provided along the periphery (perimeter) of the substrate G so as to supply a processing liquid for erasing the peripheral edge along the peripheral edge of the substrate G. The wiper peripheral device 49 has a nozzle 47 for discharging the processing liquid, and the nozzle 47 is freely raised and lowered by an actuator (opener) 89 built in the wiper peripheral device 49. In addition, the peripheral edge removing device 49 in the VU / ER unit 2 3 A refers to an anti-etching agent mainly used for erasing the peripheral edge portion of the surface on which the resist film is formed on the substrate G and the side surface of the substrate G. As shown in FIG. 2, the nozzle 47 is formed with a hole portion 86, and the processing liquid supply pipe 85 is arranged to communicate with the hole portion 86. The form of the treatment liquid discharge outlet of the nozzle 47, that is, the shape of the hole portion 86, has a continuous slit shape or a hole-shaped discharge outlet at a predetermined interval. Furthermore, as the nozzles 47, a plurality of nozzles which are continuously arranged and have one or more spouts may be used. Next, a method of using the U V / ER unit 23A described in FIG. 2 and FIG. 3 will be described. First, the upper chamber 4 1 ′ is raised, and the stage 4 5 is also raised to a position higher than the periphery of the lower chamber 4 2, and the resist is transferred from the resist coating unit (CT) 2 2 to form a resistance. After the substrate G is etched and the substrate G is placed on the stage 45, the stage 45 and the substrate G are lowered. In addition, regarding the placement of the substrate G on the stage 45, the substrate G can also be transferred to the stand-by (stand-by) state by transferring the substrate G to a predetermined position to transfer the substrate G, and return the substrate G to the return transport mechanism (please (Please read the notes on the back before filling this page) Order the paper printed by the Employees' Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs. The paper size is applicable to the Chinese National Standard (CNS) A4 specification (210X297 mm) -14- 504844 A7 B7 12) After reaching the original position, Fang lowered the platform 4 5 and so on. Next, lower the upper chamber 41 to form the processing chamber 9 1, and exhaust from the first row (please read the precautions on the back before filling in this page) to the exhaust port 4 3 and / or the second exhaust port for processing. The inside of the chamber 9'1 becomes a predetermined decompression (vacuum) environment, for example, a low vacuum state of about 2 to 10 Torr and maintained for a predetermined time. When the substrate G is subjected to a vacuum drying process in such a low vacuum environment, the volatile components contained in the resist film will gradually evaporate, so that the resist film can be formed appropriately without affecting the underside of the resist film. Drying makes it possible to effectively prevent the transfer onto the substrate G as described later. When the processing in the low-vacuum environment is completed, the actuator 8 9 is caused to move and the standby nozzle 4 7 near the bottom of the upper chamber 41 is lowered to a predetermined position, and the processing liquid for removing the peripheral edge is supplied. The supply pipe 85 is ejected from the opening at the lower end of the hole portion 86. On the other hand, the processing liquid is supplied to the supply pipe 8 7 disposed at the nozzle 50 for back washing, and from above the hole portion 8 8 The processing liquid is discharged from the opening portion, and the peripheral edge of the substrate G is completely wiped around the periphery (four sides) at the same time. Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs To eliminate the surrounding environment, you can use any state that is maintained under reduced pressure to a low vacuum state, or restored to a normal pressure (normal pressure) state. As described above, when the peripheral edge is to be erased, the resist film formed on the substrate G is properly dried, so that the resist can be easily removed (removed). In addition, when the peripheral edge is removed, if the second exhaust port 46 is mainly used to recover the processing liquid, the amount of the processing liquid flowing into the first exhaust port 43 can be reduced, so that the intention can be reduced. Maintenance equipped in the first row -15- This paper size applies to Chinese national standards (CNS > A4 size (210X297 mm) 504844 A7 B7 13 V. Description of the invention (Exhaust pump of exhaust system of port 4 3 (not shown) (Please read the precautions on the reverse side before filling out this page) After the final treatment liquid has been discharged, the processing chamber 91 is made into, for example, 0 · 1 ~ 2 Τ 〇rr The left and right high vacuum conditions are maintained for a predetermined time. Since the treatment is performed under such a high vacuum, the treatment liquid can be evaporated, and the evaporation of the volatile components contained in the anti-uranium film can be promoted. In this condition, due to The resist film has been dried under low vacuum in the previous stage. Therefore, even if it is maintained in a high vacuum environment, it will not cause a sudden (steep) evaporation of volatile components, which will adversely affect the resist film. ,dimension When the nozzle 4 7 is kept close to the ejection position of the substrate G to exhaust the processing chamber 9 1 into a low vacuum or a high vacuum, a strong airflow may be generated in the substrate G and the nozzle 4 at the beginning of the exhaust. 7 to cause a change in the thickness of the uranium-resistant film at the outer periphery of the substrate G. Therefore, when the pressure in the processing chamber 9 1 is to be reduced, it is desirable to raise the nozzle 4 7 in advance to enlarge The substrate G is spaced so that the air flow generated by the exhaust gas does not affect the resist film. Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs. After the dry substrate G is completed in a high vacuum environment, the processing chamber 9 is ordered. 1 Return to atmospheric pressure, raise the upper chamber 41 and the stage 4 5 and transfer the substrate G to the heat treatment unit (Η P) to be heat treated. The resist film of the substrate G should be in the heat treatment unit (HP). Because the two-stage drying process of so-called drying under low vacuum and drying under high vacuum has been obtained, even if it is heated, the component formation does not suddenly evaporate. Furthermore, the aforementioned drying under low vacuum and High vacuum The following drying can also be carried out in the reverse order. For example, the drying after the resist coating is applied at the high vacuum. This paper applies the Chinese National Standard (CNS) A4 specification (210X297 mm). -16-504844 A7 ___ B7_ V. Invention Note (M) (Please read the precautions on the back before filling in this page), and vacuum drying after removing the periphery is performed under low vacuum. It is also possible to perform under vacuum before removing the periphery. The drying process is performed to remove the periphery, and then the drying process is performed under high vacuum. However, in this state, it is desirable to pay attention to the time until the high vacuum is set to be longer than when the drying under low vacuum has been performed. So that the volatile components in the resist film do not erupt suddenly (suddenly). The consumer cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs has printed this way. Before the present invention is subjected to heat treatment, the resist must be dried by vacuum drying. The reason is that after heat treatment, transfer of The biggest reason for the substrate G is that the temperature experienced by the substrate G, the lift pin (lift pin), etc. will be different from other non-contact parts, so that the film thickness of the resist will correspond to The shape of the lifting pins and the like changes, and the reason for the transfer after exposure and development processing can be thought of as the line width of the circuit pattern formed on the substrate G will correspond to the shape of the lifting pins and so on. Caused by changes. That is, if the resist film is properly dried before the heat treatment according to the above-mentioned process, the fluidity of the resist will be reduced without causing the components to evaporate suddenly due to heating, making the resist It is difficult to change the film thickness of the agent, so that the transfer on the substrate G can be avoided.

Description of the invention (15) The nozzle can be traced, so that the processing time can be shortened, and the production cycle time can be shortened. In addition, the heat treatment in the plutonium P unit is also intended to shorten the drying because the uranium-resistant agent has been dried in advance. That is, as shown in FIG. 8 (a), in forming a conventional system having a vacuum drying device and a purging perimeter, a processing time of, for example, 40 seconds performed by the vacuum drying device is required, and the drying from the vacuum is performed. The processing time of the device to the peripheral device is 10 seconds and the processing time of the peripheral device is 50 seconds. The total processing time is 100 seconds. As shown in Figure 8 (b), this When the VU / ER unit 2 3A is invented, not only the transportation time as described above is not required, but also an overlap between the vacuum drying process and the erasing periphery. Therefore, the total processing time becomes, for example, about 40 seconds. The degree will be described with reference to FIG. 4. Another embodiment of the VU / ER unit. The VU / ER unit 2 3 B shown in FIG. 4 uses the same lifting mechanism 4 4 and the stage 4 5 as those used in the VU / ER unit 2 3A, and the lower chamber. 6 7 A rear cleaning nozzle 50 is provided.

In addition to the peripheral edge 9 provided in the upper chamber 6 6 4 is provided with a nozzle 6 9 along the periphery of the substrate G, and the nozzle 6 9 is provided as a processing liquid supply pipe 9 5 and communicates with a hole portion formed in the nozzle 6 9. The hole portion 9 9 of the nozzle 6 9 The morphology can be made the same as that of the aforementioned VU / ER unit 2 3A. When the nozzle 6 9 is not discharging the processing liquid, it is stored in the position shown by the dotted line in the figure, and it is to be implemented. When removing the peripheral edge, the cylinder 97 is rotated by a predetermined angle from the dotted line position (90 ° at the nozzle), and is disposed at the position shown by the solid line to form a dischargeable processing liquid. When the rotary driving nozzle 6 9 is made in this way, the nozzle 6 9 is not required to be raised and lowered, and in the decompression processing chamber 9 2, the nozzle 6 9 can be emptied to the aforementioned dotted line to make the nozzle 6 9 Since it is wide from the substrate G, the influence of the air flow on the resist film during exhaust can be reduced. Fig. 5 is a sectional view showing still another embodiment of the V U / E R unit. In the VU / ER unit 2 3 C, through-holes 7 3 are formed in the upper chamber 71 at a predetermined interval to fit on the outer periphery of the substrate G, and the through-hole 7 3 is connected to a supply pipe 74 for the processing liquid. The supply of the treatment liquid may be controlled by, for example, a shut-off valve (stop valve) 7 7. That is, the through-hole 7 3 can be used as a structure for generating the function of the discharge nozzle for removing the treatment liquid for peripheral use.

Therefore, in the lower chamber, there is no need to provide a space for the aforementioned back-washing nozzle 50, so that the lower chamber 72 itself can be made thin. When the upper and lower chambers 71 and 72 are used as described above, the entire device can be made thin and simple, and the processing chambers 9 3 formed by the upper and lower chambers 7 1 and 7 2 can also be made small. So that the exhaust time can be shortened, and vacuum pumps can also be used for small ones. In the lower chamber 72, only the second exhaust port 46 is formed. Therefore, in order to reliably discharge the processing liquid discharged from the substrate G to the outside (outside), the upper and lower chambers 7 1 and 72 will be provided so that the portion holding the substrate G can have a short wall thickness from the substrate G. . For this reason, when the uranium-resistant film is vacuum-dried immediately after the substrate G is formed, it is desirable to make the exhaust velocity small at the beginning so that the air flow generated by the exhaust gas does not change the thickness of the resist film. However, even in this state, due to the small volume of the processing chamber 93, the exhaust time will not form a longer unsuitable situation compared with the aforementioned VU / ER unit 2 3 A, 23B. .
