Further, the transport mechanism 146 takes out the substrate W after the exposure processing from the substrate carry-out portion 15b of the exposure apparatus 15 with the hand H8, and transports it to the substrate platform PASS9.
Here, as described above, the order of the substrates W placed on the placement / cooling unit P-CP (FIG. 5) by the transport mechanism 141 (FIG. 7) is from the carrier 113 (FIG. 5) to the substrate processing apparatus 100. It is equal to the order of the substrates W to be loaded. Accordingly, the order of the substrates W carried into the substrate processing apparatus 100 from the carrier 113 can be matched with the order of the substrates W carried into the exposure apparatus 15 by the transport mechanism 142 (FIG. 7). This facilitates management of the processing history of each substrate W in the exposure apparatus 15. In addition, it is possible to prevent variation in the state of the exposure processing among the plurality of substrates W carried into the substrate processing apparatus 100 from the one carrier 113.
If the exposure apparatus 15 cannot accept the substrate W, the substrate W after the cleaning and drying process is temporarily stored in the placement / buffer units P-BF1, P-BF2 by the transport mechanism 141 (FIG. 7). The
Further, when the development processing unit 139 (FIG. 2) of the second processing block 13 cannot accept the substrate W after the exposure processing, the substrate W after the PEB processing is placed by the transport mechanisms 137 and 138 (FIG. 5). The buffer units P-BF1 and P-BF2 are temporarily accommodated.
Further, when the substrate W is not normally transferred to the placement / buffer units P-BF1 and P-BF2 due to problems of the first and second processing blocks 12 and 13, the transfer mechanism until the transfer of the substrate W becomes normal. The conveyance of the substrate W from the placement / buffer units P-BF1 and P-BF2 by 141 may be temporarily stopped.
(7) Details of Placement / Buffer Unit Next, the detailed configuration of the placement / buffer units P-BF1, P-BF2 will be described. 8 and 9 are an external perspective view and a side view of the placement / buffer unit P-BF1. FIG. 10 is a plan view for explaining the loading and unloading operations of the substrate W with respect to the placement / buffer unit P-BF1. The configuration of the placement / buffer unit P-BF2 is the same as the configuration of the placement / buffer unit P-BF1 shown in FIGS.
As shown in FIGS. 8 and 9, frames 911 and 912 extending in the vertical direction (Z direction) are provided at the boundary between the second processing block 13 (FIG. 1) and the cleaning / drying processing block 14A. .

A pair of fixing members 91 are attached to the frames 911 and 912, respectively.
Each fixing member 91 is provided with a plurality of convex portions 921 protruding in the horizontal direction (X direction) at regular intervals in the vertical direction. One end portions of the plurality of support plates 92 are respectively fixed to the upper and lower surfaces of the convex portion 921 of one fixing member 91, and the other end portions of the plurality of support plates 92 are fixed to the upper and lower surfaces of the convex portion 921 of the other fixing member 91. Are fixed respectively. Thereby, the plurality of support plates 92 are arranged at equal intervals in the vertical direction in a horizontal posture.
A plurality (three in this example) of support pins 93 are provided on the upper surface of each support plate 92. On each support plate 92, the substrate W is supported by a plurality of support pins 93. Thereby, the plurality of substrates W can be accommodated in the placement / buffer unit P-BF1.
As shown in FIGS. 10A to 10C, the hands H1 and H2 of the transport mechanism 137 (FIG. 5), the hands H3 and H4 of the transport mechanism 141 (FIG. 7), and the hand H5 of the transport mechanism 142 (FIG. 7). , H6 each have a substantially U shape.
As a result, the hands H1 to H6 of the transport mechanisms 137, 141, 142 do not interfere with the frames 911, 912 and the support pin 93, and the substrate W is placed on the support pin 93 and the substrate from above the support pin 93. W can be received.
As described above, the placement / buffer unit P-BF1 is configured such that the substrate W can be carried in and out by the transport mechanisms 137, 141, and 142. Similarly, the placement / buffer unit P-BF2 is configured such that the substrate W can be carried in and out by the transport mechanisms 138, 141, and 142.
The substrate platform PASS9 (FIG. 5) may have the same configuration as the placement / buffer units P-BF1 and P-BF2.
(8) Details of Placement / Cooling Unit Next, a detailed configuration of the placement / cooling unit P-CP will be described. 11 is an external perspective view of the placement / cooling section P-CP, FIG. 12 is a view of the placement / cooling section P-CP as viewed from the + X direction side, and FIG. 13 is a placement / cooling. It is a typical cross section of part P-CP. FIG. 14 is a schematic cross-sectional view for explaining the loading and unloading operations of the substrate W with respect to the placement / cooling unit P-CP. 11 and 12 show three placement / cooling sections P-CP stacked one above the other.
As shown in FIG. 11, each placement / cooling unit P-CP has a housing 95. The housing 95 has an upper surface portion 95a, a lower surface portion 95b, a front surface portion 95c, a rear surface portion 95d, and side surface portions 95e and 95f. Upper surface 95a and lower surface 95b is parallel to the XY plane, the front portion 95 c and the rear surface portion 95 d is parallel to the YZ plane.
The side surface portions 95e and 95f extend from both end portions of the rear surface portion 95d along the XZ plane, bend inward so as to approach each other, and are integrated with both end portions of the front surface portion 95c .
The side surface portions 95e, the substrate carrying port 951 extending laterally formed on the side surface portion 95 f, the substrate carrying port 952 extending laterally (see FIG. 13 described later) is formed. As shown in FIG. 12, a substrate carry-out port 953 extending in the lateral direction (Y direction) is formed in the rear surface portion 95d.
As shown in FIG. 13, a cooling plate 954 is provided inside each housing 95. The cooling plate 954 is cooled by a cooling mechanism (not shown). A plurality (three in this example) of support pins 955 are provided on the cooling plate 954. The substrate W is placed on these support pins 955.
Note that shutters for opening and closing the substrate carry-in ports 951 and 952 and the substrate carry-out port 953 may be provided.
As shown in FIG. 14A, the hands H3 and H4 of the transport mechanism 141 (FIG. 7) can enter the housing 95 from the substrate carry-in port 951 and place the substrate W on the support pins 955. it can. 14B, the hands H5 and H6 of the transport mechanism 142 (FIG. 7) enter the housing 95 from the substrate carry-in port 952, and place the substrate W on the support pins 955. be able to.
Further, as shown in FIG. 14C, the hands H7 and H8 of the transport mechanism 146 (FIG. 5) enter the housing 95 from the substrate carry-out port 953 and hold the substrate W on the support pins 955. It can be carried out from the placement / cooling section P-CP.
As described above, the placement / cooling unit P-CP is configured to be able to carry in and out the substrate W by the transport mechanisms 141, 142, and 146.
In the present embodiment, as described above, the substrate W is carried into the placement / cooling unit P-CP by the hand H4 of the transport mechanism 141. The substrate W placed on the support pins 955 is cooled to a temperature suitable for the exposure process by the cooling plate 954. Thereafter, the substrate W after the cooling process is unloaded from the placement / cooling unit P-CP by the hand H7 of the transport mechanism 146 (FIG. 1 ).
(9) Effects of the present embodiment (9-1)
In the present embodiment, in the cleaning / drying processing block 14A, the transport mechanism 141 moves the substrate W between the placement / buffer units P-BF1, P-BF2, the cleaning / drying processing unit 161, and the placement / cooling unit P-CP. The transport mechanism 142 can transport the substrate W between the placement / buffer units P-BF1, P-BF2, the cleaning / drying processing unit 162, the heat treatment unit 133, and the placement / cooling unit P-CP. Can do.
This diversifies the options for the transport path of the substrate W in the cleaning / drying processing block 14A. Accordingly, the substrate can be transported through an optimum path according to the processing content of the substrate W in the first and second processing blocks 12 and 13 and the cleaning / drying processing units 161 and 162. As a result, the transfer efficiency of the substrate W can be improved, and the throughput can be improved.
In the present embodiment, in the cleaning / drying processing block 14 </ b> A, the substrate W before the exposure processing is transported by the transport mechanism 141, and the substrate W after the exposure processing is transported by the transport mechanism 142. In the carry-in / carry-out block 14B, the substrate W before the exposure process is transferred by the hand H7 of the transfer mechanism 146, and the substrate W after the exposure process is transferred by the hand H8 of the transfer mechanism 146.
Thus, in the cleaning / drying processing block 14A and the carry-in / carry-out block 14B, the transport path of the substrate W before the exposure process and the transport path of the substrate W after the exposure process are independently secured. In this case, the operations of the transport mechanisms 141, 142, and 146 are simplified as compared with the case where the transport path of the substrate W before the exposure process intersects with the transport path of the substrate W after the exposure process. Thereby, the transfer efficiency of the substrate W is improved, and the throughput can be improved.
Further, in the cleaning / drying processing block 14A, the substrate W before the exposure processing is placed by the transport mechanism 141 from the placement / buffer units P-BF1, P-BF2 via the cleaning / drying processing unit 161 to the placement / cooling unit P-. The substrate W that has been transferred to the CP and subjected to the exposure process is transferred by the transfer mechanism 142 from the substrate platform PASS9 to the upper thermal processing unit 303 or the lower thermal processing unit 304 via the cleaning / drying processing unit 162. In the loading / unloading block 14 </ b> B, the substrate W before the exposure process is transported from the placement / cooling unit P-CP to the exposure device 15 by the hand H <b> 7 of the transport mechanism 146, and the substrate W after the exposure process is transported by the transport mechanism 146. It is transported from the exposure device 15 to the substrate platform PASS9 by the hand H8.
Thereby, in the cleaning / drying processing block 14A and the carry-in / carry-out block 14B, the substrate W before the exposure processing and the substrate W after the exposure processing do not contact indirectly. Therefore, cross contamination (cross-contamination) between the substrate W before the exposure process and the substrate W after the exposure process can be prevented.
Further, since the transport path of the substrate W before the exposure process and the transport path of the substrate W after the exposure process are independent from each other, the substrate W after the exposure process can be smoothly transferred to the heat treatment unit PHP of the second processing block 13. Can be conveyed.
Thereby, the PEB processing of the substrate W can be performed quickly after the exposure processing. As a result, the chemical reaction in the resist film can be promptly promoted, and a desired exposure pattern can be obtained. Further, when processing a plurality of substrates W continuously, the time from the exposure process to the PEB process can be made substantially constant. As a result, variations in exposure pattern accuracy can be prevented.
Further, the transport mechanisms 137, 141, 142 can carry the substrate W into and out of the placement / buffer unit P-BF1, and the transport mechanisms 138, 141, 142 serve the placement / buffer unit P-. It is possible to carry in and carry out the substrate W with respect to the BF2. Accordingly, the substrate W can be accommodated in the placement / buffer units P-BF1 and P-BF2 at various timings before and after the exposure processing. As a result, the transport timing of the substrate W by the transport mechanisms 137, 138, 141, 142 can be easily adjusted.
Further, the transport mechanisms 141, 142, and 146 can carry the substrate W into and out of the substrate platform PASS9 and the placement / cooling unit P-CP. In this case, it is possible to load and unload the substrate W from three directions with respect to the placement / buffer units P-BF1, P-BF2, the substrate placement unit PASS9, and the placement / cooling unit P-CP, respectively. Thus, it is possible to easily change the transport path of the substrate W.
In the first and second processing blocks 12 and 13, the upper processing sections (coating processing chambers 21, 22, and 32 and the development processing chamber 31 (FIG. 2), the upper transport chambers 125 and 135 (FIG. 5), and the upper processing block are provided. Heat treatment sections 301 and 303 (FIG. 3)) and lower processing sections (coating process chambers 23, 24 and 34 and development processing chamber 33 (FIG. 2), lower transfer chambers 126 and 136 (FIG. 5), and lower heat treatment section 302 304 (FIG. 3)), the processing of the plurality of substrates W can proceed in parallel.
Thereby, the throughput of the first and second processing blocks 12 and 13 can be improved without increasing the transport speed of the substrate W by the transport mechanisms 127, 128, 137 and 138. In addition, since the transport mechanisms 127, 128, 137, and 138 are provided above and below, an increase in the footprint of the substrate processing apparatus 100 can be prevented.
The upper processing unit and the lower processing unit of the first and second processing blocks 12 and 13 have the same configuration. Accordingly, even when a failure or the like occurs in one of the upper processing unit and the lower processing unit, the processing of the substrate W can be continued using the other processing unit. As a result, the versatility of the substrate processing apparatus 100 is improved.
Further, in the cleaning / drying processing unit SD1, by cleaning the substrate W before the exposure processing, a part of the components of the resist cover film on the substrate W is eluted and washed away. For this reason, even if the substrate W comes into contact with the liquid in the exposure apparatus 15 , the components of the resist cover film on the substrate W are hardly eluted in the liquid. Further, dust and the like attached to the substrate W before the exposure process can be removed. As a result, contamination in the exposure apparatus 15 is prevented.
Also, washing in Kiyoshiinui燥processing unit SD1, by drying process is performed to the substrate W after the cleaning treatment, the liquid adhering to the substrate W during the cleaning process is removed, in the atmosphere on the substrate W after the cleaning treatment Dust and the like are prevented from adhering again. As a result, contamination within the exposure apparatus 15 can be reliably prevented.
Further, the washing Kiyoshiinui燥processing unit SD2, by drying the substrate W after the exposure process is performed, the liquid adhering to the substrate W during the exposure processing is prevented from falling into the substrate processing apparatus 100 . In addition, by performing a drying process on the substrate W after the exposure process, it is possible to prevent dust and the like in the atmosphere from adhering to the substrate W after the exposure process, thereby preventing contamination of the substrate W.
In addition, since it is possible to prevent the substrate W to which the liquid has adhered from being transported through the substrate processing apparatus 100, the liquid that has adhered to the substrate W during the exposure process affects the atmosphere in the substrate processing apparatus 100. Can be prevented. Thereby, temperature and humidity adjustment in the substrate processing apparatus 100 is facilitated.
Further, the liquid adhering to the substrate W during the exposure process is prevented from adhering to the transport mechanisms 116, 127, 128, 137, 138, 141, 142. Therefore, it is possible to prevent the liquid from adhering to the substrate W before the exposure process. This prevents dust and the like in the atmosphere from adhering to the substrate W before the exposure process, so that contamination of the substrate W is prevented. As a result, it is possible to prevent the resolution performance from being deteriorated during the exposure process and to prevent contamination in the exposure apparatus 15.
In addition, the resist component or the resist cover film component is reliably prevented from eluting into the liquid remaining on the substrate W while the substrate W is transported from the cleaning / drying processing unit SD2 to the development processing chambers 31 and 33. be able to. Thereby, deformation of the exposure pattern formed on the resist film can be prevented. As a result, it is possible to reliably prevent a reduction in line width accuracy during the development process.

Carried to PHP.
As described above, in the first modification, the cleaning and drying processing of the substrate W before the exposure processing is performed in both the cleaning and drying processing units 161 and 162. Thereby, the efficiency of cleaning and drying processing of the substrate W before the exposure processing is improved. Accordingly, when there is no need to perform cleaning and drying after the exposure process, it becomes possible to process a large amount of substrates W more quickly.
In addition, at the time of cleaning and drying processing of the substrate W before the exposure processing, the cleaning processing of the back surface and end portions of the substrate W may be performed as described above. In that case, the processing time becomes long and the throughput decreases.
Thus, as in this example, the cleaning and drying processing of the substrate W before the exposure processing is performed by both the cleaning / drying processing units 161 and 162, thereby suppressing a decrease in throughput due to an increase in processing time.
In the first modification, one of the hands H5 and H6 is used when the substrate W before the exposure processing by the transport mechanism 142 is transported, and the hands H5 and H6 are transported when the substrate W after the exposure processing by the transport mechanism 142 is transported.

As shown in FIG. 16, in the second modification, a plurality (five in this example) of cleaning / drying processing units SD2 are provided in both of the cleaning / drying processing units 161, 162.
An example of the transport path of the substrate W in the cleaning / drying processing block 14A of FIG. 16 will be described mainly using FIG. 5 and FIG.
The substrate W after edge exposure placed on the placement / buffer units P-BF1, P-BF2 by the transport mechanisms 137, 138 (FIG. 5) is placed on the placement / cooling unit by the transport mechanisms 141, 142 (FIG. 16). It is conveyed to P-CP (FIG. 5).
The substrate W after the exposure processing placed on the substrate platform PASS9 by the transport mechanism 146 (FIG. 5) is transported to the cleaning / drying processing unit SD2 of the cleaning / drying processing unit 161 by the transport mechanism 141 (FIG. 16).

The substrate W that has been cleaned and dried in the cleaning / drying processing unit SD2 of the cleaning / drying processing unit 161 is transported to the substrate platform PASS9 (FIG. 5) by the transport mechanism 141. The substrate W transferred to the substrate platform PASS9 is transferred to the heat treatment unit PHP of the upper heat treatment unit 303 or the heat treatment unit PHP of the lower heat treatment unit 304 by the transfer mechanism 142 (FIG. 16).
The substrate W that has been cleaned and dried in the cleaning / drying processing unit SD2 of the cleaning / drying processing unit 162 is transported by the transport mechanism 142 to the thermal processing unit PHP of the upper thermal processing unit 303 or the lower thermal processing unit 304.
As described above, in the second modification, the cleaning and drying processing of the substrate W after the exposure processing is performed in both the cleaning and drying processing units 161 and 162. Thereby, the efficiency of cleaning and drying processing of the substrate W after the exposure processing is improved. Therefore, when it is not necessary to perform the cleaning and drying process before the exposure process, it is possible to process a large number of substrates W more quickly.
In the second modification, one of the hands H3 and H4 is used when the substrate W before the exposure processing by the transport mechanism 141 is transported, and the hands H3 and H4 are transported when the substrate W after the exposure processing by the transport mechanism 141 is transported. The other is used, and one of the hands H5 and H6 is used when transporting the substrate W before the exposure processing by the transport mechanism 142, and the other of the hands H5 and H6 is used when transporting the substrate W after the exposure processing by the transport mechanism 142. May be. In this case, the substrate W before the exposure process and the substrate W after the exposure process are prevented from being indirectly contacted via the transport mechanisms 141 and 142. Thereby, cross contamination between the substrate W before the exposure process and the substrate W after the exposure process can be prevented.
(10-3) Third Modification A third modification will be described with respect to differences from the above embodiment. FIG. 17 is a diagram showing an internal configuration of the cleaning / drying processing block 14A in the third modified example. FIG. 17 is a view of the cleaning / drying processing block 14A as viewed from the + X direction side.

In this example, a single cleaning / drying processing unit SD1 and a plurality (four in this example) of cleaning / drying processing units SD2 are provided.
An example of the transport path of the substrate W in the cleaning / drying processing block 14A will be described mainly with reference to FIGS.
The substrate W after edge exposure placed on the placement / buffer units P-BF1 and P-BF2 by the transport mechanisms 137 and 138 (FIG. 5) is cleaned by the transport mechanism 141 (FIG. 17) by the cleaning / drying processing unit 161. It is transported to the drying processing unit SD1 or transported to the cleaning / drying processing unit SD1 of the cleaning / drying processing section 162 by the transport mechanism 142.
The substrate W that has been cleaned and dried in the cleaning / drying processing unit SD1 of the cleaning / drying processing unit 161 is transported to the placement / cooling unit P-CP (FIG. 5) by the transport mechanism 141. Further, the substrate W that has been cleaned and dried in the cleaning / drying processing unit SD1 of the cleaning / drying processing unit 162 (FIG. 17) is transported by the transport mechanism 142 to the placement / cooling unit P-CP (FIG. 5). .

The washing and drying process is performed.
As described above, when the cleaning process of the back surface and the edge of the substrate W is performed during the cleaning and drying process of the substrate W before the exposure process, the processing time becomes long. As a result, the time required for cleaning and drying the substrate W before the exposure processing is longer than the time required for cleaning and drying the substrate W after the exposure processing. Therefore, as in this example, the number of the cleaning / drying processing units SD1 is made larger than the number of the cleaning / drying processing units SD2, thereby efficiently cleaning and drying the substrate W before and after the exposure processing. Can do.
Further, if the cleaning / drying processing unit SD1 is provided with a mechanism for cleaning the back surface and the edge of the substrate W, the cleaning / drying processing unit SD1 is increased in size. Therefore, many cleaning / drying processing units SD1 cannot be installed in the cleaning / drying processing unit 161. Therefore, by providing the cleaning / drying processing unit 162 with the cleaning / drying processing unit SD1, it is possible to secure a sufficient number of the cleaning / drying processing units SD1.
In the third modification, one of the hands H5 and H6 is used when the substrate W before the exposure processing by the transport mechanism 142 is transported, and the hands H5 and H6 are transported when the substrate W after the exposure processing by the transport mechanism 142 is transported. The other may be used.

Thereby, cross contamination between the substrate W before the exposure process and the substrate W after the exposure process can be prevented.
(10-4) Other Modifications Other units may be provided instead of the cleaning / drying processing units SD1 and SD2. For example, a unit for inspecting the end of the substrate W before and after the exposure processing may be provided, or a unit for inspecting the state of the film on the substrate W before and after the exposure processing may be provided.
