It is sectional drawing of the substrate processing apparatus 1c which concerns on 4th Embodiment. It is a perspective view of the conventional substrate processing apparatus.

  The substrate processing apparatus 1 according to the embodiment of the present invention performs a heating process (or a cooling process) on a substrate. However, this is merely an example, and the present invention can also be applied when the substrate processing apparatus 1 performs a process other than the heat treatment on the substrate. The substrate to be processed by the substrate processing apparatus 1 is not particularly limited. For example, a semiconductor wafer, a glass substrate for a liquid crystal display device, a glass substrate for a PDP (plasma display panel), a glass substrate for a magnetic disk, and a glass for an optical disk. A substrate and a ceramic substrate for a magnetic disk. Below, the structure of the said substrate processing apparatus 1 is demonstrated, referring FIGS. 1-8.

  FIG. 1 is a perspective view of the substrate processing apparatus 1 according to the first embodiment of the present invention as viewed from the maintenance area side. In FIG. 1, an XYZ orthogonal coordinate system is defined in which the floor surface FL on which the substrate processing apparatus 1 is installed is the XY plane. The same XYZ rectangular coordinate system is used in the subsequent figures.

As shown in FIG. 1, the substrate processing apparatus 1 is a multi-stage apparatus in which a plurality of processing chambers 21 are stacked in a vertical direction inside a processing apparatus frame 2 and are stacked in this embodiment. The pitch of each stage in the Z direction is about 1 m. Although FIG. 1 shows the substrate processing apparatus 1 having three processing chambers 21, the number of processing chambers 21 may be two or less or four or more. The processing apparatus frame 2 is a substantially rectangular parallelepiped casing formed by connecting rod-like members such as pipes and angles that form a skeleton, and functions as a support structure that supports the processing chamber 21 inside. A plate-like member serving as an exterior or a shelf is attached to the skeleton of the processing apparatus frame 2 as necessary. Each of the processing chambers 21 has a substantially rectangular parallelepiped shape with a lid, and can be separated into a box-shaped main body 211 serving as a lower member and an upper lid 212 serving as an upper member.
The substrate is transferred to the processing chamber 21 by a substrate transfer device (not shown) from the + Y direction or the + X direction and the −X direction, and a predetermined process is performed.

  A maintenance frame 3 is provided adjacent to the substrate processing apparatus 1 adjacent to the −Y side of the processing apparatus frame 2. Similarly to the processing apparatus frame 2, the maintenance frame 3 is also formed by connecting rod-like members such as pipes and angles serving as a skeleton, and has a substantially rectangular parallelepiped shape.

  FIG. 2 is a front view of the substrate processing apparatus 1 according to the embodiment of the present invention as viewed from the maintenance frame 3 side. 3 is a cross-sectional view taken along the line AA of FIG.

  As shown in FIGS. 1 and 2, the maintenance frame 3 is provided with a working scaffold 31 and a beam portion 32 at substantially the same height as the surface on which the processing chamber 21 accommodated in the processing apparatus frame 2 is disposed. Has been. Corresponding to the processing chambers 21 arranged in a stacked manner, a working scaffold 31 and a beam portion 32 are also arranged. In this embodiment, similarly to the stacking pitch of the processing chamber 21, the stacking pitch of each stage arranged in the maintenance frame 3 is about 1 m, respectively.

  The work scaffold 31 is a substantially plate-like member formed using, for example, an aluminum material, and is fixedly arranged in the Y direction with respect to each stage of the maintenance frame 3. The work scaffold 31 is mainly used for pulling out the processing chamber 21 arranged in the processing apparatus frame 2 to the maintenance frame 3.

  In addition, each work scaffold 31 is arranged in a step difference in the X direction with respect to the work scaffold 31 adjacent in the vertical direction. In other words, the work scaffolds 31 of each height are arranged with regions that do not overlap each other when viewed from the Z direction with respect to the work scaffolds 31 adjacent in the vertical direction. Therefore, the worker can easily move the processing chamber 21 while standing on the work scaffold 31 and walking in the Y direction.

  The beam portion 32 is a rod-shaped member formed using, for example, an aluminum material. The beam portion 32 is formed so that the Y beam 321 extending in the Y axis direction and the X beam 322 extending in the X axis direction intersect with each other, and has sufficient strength for an operator to work on the upper surface. I have. A part of the work scaffold 31 is fixed to the Y beam 321 of the beam portion 32, and the strength of the work scaffold 31 is secured by the beam portion 32.

  As shown in FIG. 3, each processing chamber 21 is supported by the processing apparatus frame 2 at a processing time position (indicated by a solid line) inside the processing apparatus frame 2 when processing a substrate. . When a maintenance operation is performed, the processing chamber 21 is supported by the maintenance frame 3 at a maintenance position (a position indicated by a virtual line) inside the maintenance frame 3. Each of the main body 211 and the upper lid 212 is independently movable between a processing position and a maintenance position.

  The main body 211 or the upper lid 212 of the processing chamber 21 disposed at the maintenance position is located below the work scaffold 31 and the beam portion 32. Therefore, an operator can perform maintenance work on the main body 211 or the upper lid 212 of the work room by getting on the work scaffold 31 and the beam part 32.

  Further, since the work scaffold 31 and the beam portion 32 are always arranged on the maintenance frame 3, it is not necessary to install a temporary scaffold during maintenance work, and the work time can be shortened.

  The work scaffold 31 disposed on the maintenance frame 3 is disposed in the drawer region A1 occupying the central portion in the X direction inside the maintenance frame 3. This pull-out area A1 is an area (the second work area in the claims) that does not have the X beam 322 of the beam portion 32 and has a blowout structure in the vertical direction. Therefore, in the pull-out area A1, when the processing unit 21 is pulled out from the processing device frame 2 in the −Y direction on the maintenance frame 3 side, it is possible for the worker to work in a standing posture. Furthermore, since the work scaffold 31 extends in the Y direction, the worker can move while pulling out the processing unit 21 on the work scaffold 31.

  The beam portion 32 is formed in the maintenance area A2 located on the + X side and the −X side inside the maintenance frame 3. The maintenance area A2 is an area including the X beam 322 of the beam portion 32 (a first work area in the claims). The operator performs maintenance work on the processing chamber 21 from between the beams while riding on the Y beam 321 and the X beam 322 of the beam portion 32. In addition, maintenance work can be performed on the processing chamber 21 moved to the maintenance position from any direction.

  Further, the main body 211 and the upper lid 212 are provided with a pull-out handle 23. When the operator pulls out the main body 211 and the upper lid 212, the main body 211 and the upper lid 212 can be pulled out by moving in the −Y direction on the work scaffold 31 while holding the pulling handle 23.

  Next, the moving mechanism 22 will be described with reference to FIG. As conceptually shown in FIGS. 2 and 3, the main body 211 and the upper lid 212 of the processing chamber 21 are connected to the moving mechanism 22. FIG. 4 is a cross-sectional view of the moving mechanism 22 viewed from the inside of the substrate processing apparatus 1 in the + X direction.

  Specifically, the moving mechanism 22 includes a main body rail 221, an upper lid rail 222, a main body guide member 223, an upper lid guide member 224, an upper lid up / down mechanism 225, and a guide roller 226.

  In FIG. 4, attention is paid to the structure of the moving mechanism 22, and the main body 211 and the upper lid 212 are indicated by phantom lines for easy explanation. Further, only a part of the work scaffold 31 and the beam part 32 arranged in the maintenance frame are shown, and the others are omitted.

  The main body rail 221 is arranged so as to communicate in the Y direction from each stage of the processing apparatus frame 2 to a corresponding stage of the maintenance frame 3. The main body guide member 223 is connected to a main body rail 221 extending in the Y direction via a guide roller 226. The main body guide member 223 is connected to the main body 211 indicated by a two-dot chain line. Thus, the main body 211 can be moved from the processing apparatus frame 2 to the maintenance frame 3 together with the main body guide member 223. FIG. 4 shows a state in which the main body 211 is pulled out to the maintenance frame 3 side while the upper lid 212 is held on the processing apparatus frame 2 side.

  Similarly, the upper lid rail 222 is arranged so as to communicate in the Y direction from each stage of the processing apparatus frame 2 to a corresponding stage of the maintenance frame 3. The upper lid guide member 224 is connected to an upper lid rail 222 extending in the Y direction via a guide roller 226. Further, the upper lid guide member 224 is connected to the upper lid 212 indicated by a two-dot chain line via an up / down mechanism 225. Accordingly, the upper lid 212 can be moved from the processing apparatus frame 2 to the maintenance frame 3 together with the vertical mechanism 225 and the upper lid guide member 224.

  The vertical mechanism 225 inserted between the upper lid guide member 224 and the upper lid 212 is a drive mechanism for moving the upper lid 212 up and down with respect to the upper lid guide member 224, and specifically includes a ball screw or a cylinder. can do. Accordingly, the substrate can be processed by moving the upper lid 212 up and down relative to the main body 211 and carrying the substrate into the processing chamber 21 by a substrate transport mechanism (not shown).

  In the first embodiment, an example in which the work scaffold 31 is installed at one place with respect to the processing chamber 21 is shown, but the present invention is not limited to the above-described embodiment.

  FIG. 5 is a front view of the substrate processing apparatus 1a according to the second embodiment of the present invention as viewed from the maintenance frame 3 side. 6 is a cross-sectional view taken along the line BB of FIG.

  As shown in FIG. 5, two working scaffolds 31 are arranged in each stage of the maintenance frame 3 of the substrate processing apparatus 1a. Further, as shown in FIG. 6, a temporary scaffold 33 is disposed between the left and right work scaffolds 31. The same components as those in the first embodiment are denoted by the same reference numerals (hereinafter the same).

  The number of work scaffolds 31 arranged for each stage may be appropriately selected depending on the arrangement pitch of the processing chambers 21 and the maintenance work thereof. However, at least one work scaffold 31 in each stage needs to be arranged in the aforementioned drawer area A1. In FIG. 6, of the two work scaffolds 31, the work scaffold 31 on the + X side is arranged in the drawer area A1. In the drawing area A1, the X beam 322 that prevents the drawing work is not installed. Therefore, the worker can move while walking while standing on the work scaffold 31 on the side arranged in the drawer area A1 when the processing unit 21 is pulled out.

  Moreover, workability can be further improved by disposing the temporary scaffold 33 between the work scaffolds 31 after the drawing work is finished. The temporary scaffold 33 is a substantially plate-like member formed using, for example, an aluminum material similarly to the work scaffold 31, and a predetermined member between the work scaffolds 31 is formed by a fixing member formed at an end of the temporary scaffold 33. It is possible to fix the position. Since the temporary scaffold 33 can be formed lighter than the work scaffold 31, it can be appropriately moved depending on the point where the maintenance work is performed.

  With such a configuration, even when the substrate processing apparatus 1a and the maintenance frame 3 are enlarged due to the increase in size of the substrate, the work scaffold 31 can be arranged only at a necessary portion. Further, by using the temporary scaffold 33, the maintainability at the intermediate point between the left and right work scaffolds 31 is improved.

  Moreover, although the beam part 32 arrange | positioned at each step | level of the maintenance frame 3 showed the same shape in the above-mentioned embodiment, this invention is not limited to the above-mentioned embodiment.

  FIG. 7 is a front view of the substrate processing apparatus 1b according to the third embodiment of the present invention as viewed from the maintenance frame 3 side.

  As shown in FIG. 7, in the maintenance frame 3 of the substrate processing apparatus 1b, a beam portion 32 and a work scaffold 31 are arranged at each stage. The beam portions 32 of the substrate processing apparatus 1b are stepped in the X direction at each step. Similarly, the respective work scaffolds 31 are arranged in a step difference in the X direction with respect to the work scaffolds 31 adjacent in the vertical direction. By arranging the beam portion 32 and the work scaffold 31 in this way, the operator can move while pulling out the processing unit 21 on the work scaffold 31 arranged in each stage.

  Note that, in the third embodiment, the working scaffolds 31 at each height partially have regions overlapping each other when viewed from the Z direction with respect to the working scaffolds 31 adjacent in the vertical direction. However, since a drawing work passage 34 (shown by a virtual line in FIG. 7) extending in the Y direction is secured on the work scaffold 31, the drawing work can be easily performed. In other words, the work scaffold 31 may have a partially overlapping area when viewed from the Z direction as long as a movable work area is secured so that the processor 21 can be moved while being pulled out.

  By adopting such a configuration, it is possible to secure a space necessary for the drawing work while simplifying the configuration of the maintenance frame 3.

  Similarly, in the above-described first and second embodiments, the work scaffolds 31 arranged on each stage of the maintenance frame 3 are completely in the X direction with respect to the work scaffolds 31 adjacent in the vertical direction. Although they are arranged in a stepped manner, the drawing work passage 34 is secured on the work scaffold 31 as in the third embodiment (partially overlapped as shown by the phantom line in FIG. 7). Any difference is sufficient.

  In the first to third embodiments described above, the working scaffolds 31 arranged at the respective stages of the maintenance frame 3 are fixedly arranged with respect to the maintenance frame 3. Is not limited to the above-described embodiment.

  FIG. 8 is a front view of the substrate processing apparatus 1c according to the fourth embodiment of the present invention as viewed from the maintenance frame 3 side. 9 is a cross-sectional view taken along the line CC of FIG.

  As shown in FIG. 8, in the maintenance frame 3 of the substrate processing apparatus 1c, a beam portion 32 and a movable work scaffold 311 are arranged at each stage. The movable work scaffold 311 is a substantially plate-like member that is formed using, for example, an aluminum material and extends in the Y direction.

  As shown in FIG. 9, the + Y side and −Y side ends of the movable work scaffold 311 are installed via the slide mechanism 312 with respect to the frame corresponding to each stage of the maintenance frame 3.

  The slide mechanism 312 includes a guide member 313 disposed on the maintenance frame 3 and a base 314 provided on the guide member 313 so as to be slidable in the X direction. The base 314 is fixed to the + Y side and the −Y side end of the movable work scaffold 311. Therefore, the movable work scaffold 311 and the base 314 can be moved together in the direction of the arrow in the figure (X direction). Further, the base 314 can be fixed so as not to move with respect to the guide member 313.

When the processing unit 21 is pulled out in the maintenance work, the movable work scaffold 311 at a predetermined stage is moved to the pull-out area A1 without the beam part 32 and fixed to the guide member 313 disposed on the maintenance frame 3. To do. The lead-out area A1 is an area where there is no X beam 322 of the beam portion 32 and has a blowout structure in the vertical direction. The worker performs a drawing operation of the processing chamber 21 by standing and moving on the movable work scaffold 311 arranged in each stage.
In addition, after the processing unit 21 is pulled out, the movable work scaffold 311 at a predetermined stage can be moved by the slide mechanism 312 in accordance with a point where the work is performed.

  With such a configuration, the work scaffold 311 can be disposed in an area where it can move while standing. Further, since the movable work scaffold 311 can be arbitrarily moved with respect to a point requiring maintenance, the number of work scaffolds for performing the maintenance work can be reduced.

  Moreover, this invention is not limited to the above-mentioned embodiment, A various aspect can be considered in the range which does not change a summary.

  For example, the work scaffold 31 and the movable work scaffold 311 may not be a rectangular parallelepiped shape as shown in FIGS. 1 to 9, but may be formed by a frame body and a plate-like member. Ribs or the like may be provided as appropriate. A safety fence or the like may be provided for the purpose of improving work safety. If a safety fence is permanently installed at each stage, it will hinder the movement of the processing chamber 21, so that it is desirable to have a structure that is separately attached to the necessary stage.

  Further, for example, if the moving mechanism 22 is configured to move the processing chamber 21 including the main body 211 and the upper lid 212 from the processing apparatus frame 2 to the maintenance frame 3, the moving mechanism 22 may be applied to the rail, guide member, roller, or the like as described above. It is not limited and can be appropriately selected by those skilled in the art. Specifically, a linear guide, a floating guide, a feed mechanism using a ball screw, and the like can be considered.

  Further, the processing chamber 21 is separated into the main body 211 and the upper lid 212 and can be independently moved from the processing apparatus frame 2 to the maintenance frame 3, but is not limited thereto. That is, a configuration in which the processing chamber 21 moves as a unit, or a configuration in which the processing chamber 21 is divided by a division method other than the main body 211 and the upper lid 212 and moves independently from each other may be employed.

  In the above-described embodiment, the drawer area A1 is arranged at the center of the maintenance frame 3. However, the present invention is not limited to this. That is, the drawer area A1 may be disposed at the + X side end or the −X side end of the maintenance frame 3, and the maintenance area A2 may be disposed at the center.

In the above-described embodiment, the maintenance frame 3 completely surrounds the processing chamber 21, but the present invention is not limited to this. That is, the maintenance frame 3 has a short configuration in the Y direction, and during maintenance, the half of the processing chamber 21 is maintained by pulling out the half of the processing chamber 21, and then the remaining half is pulled out for maintenance. Is also possible.
