Anchor is controlled its driving with cylinder 47,48 by the 1st cylinder controller 51.Anchor is controlled its driving with cylinder 49 by the 2nd cylinder controller 52.Platform is controlled its driving by platform with cylinder controller 53 with cylinder 55.Master controller 50 carries out the control generally of drying under reduced pressure unit (VD), controls vacuum pump 54 according to the signal that transducer 64 detects.In addition, master controller 50 comes control cylinder controller 51,52,53 according to the input signal from input part 57.Input part 57 is guidance panels of handling with the input of manually carrying out contents processing of operating personnel etc. for example.
Below, the action of the drying under reduced pressure unit (VD) of such formation is described.
For example, operating personnel import the method for operation of drying under reduced pressure unit (VD) by input part 57.For example when batch be the method for operation of unit input coating development processing apparatus 1 integral body, the method for operation of importing drying under reduced pressure unit (VD) just can.Operating personnel import as method of operation 1 such as kind of for example glass substrate.The kind of glass substrate is divided according to the difference of the quantity of the regional A that becomes finished product on example glass substrate G1, the G2 as shown in Figure 7 and Figure 8.Fig. 7 represents for example to form 2 finished product districts, and Fig. 8 represents for example to form 3 finished product districts.
In addition, if form the substrate in 3 finished product districts, as shown in figure 10, under the control of the 1st cylinder controller 51, drive with cylinder 47,48 by anchor.For the substrate G2 that forms 3 finished product districts, non-product region is positioned at oblique line subregion as shown in Figure 8.Therefore in this case, master controller 50 drives the non-product region of supporting the substrate G2 in 3 finished product districts of formation with anchor 70a, 70b by making cylinder 47,48.
So after having kept substrate, with the driving of cylinder 55 platform 40 is descended by platform, upper container 46 is assembled on the bottom container 36, and is airtight in the container., make the pressure of container in reduce pressure regulation, carry out the dried of substrate thereafter.
After the dried, upper container 46 separates from bottom container, with the driving of cylinder 55 platform 40 is risen and by there not being illustrated transfer robot transmission substrate by platform.
In above present embodiment, owing to carrying out the switching of cylinder 47,48 and 49 corresponding to the kind of substrate, so just can prevent vestige at the product region transfer printing anchor 70 of substrate.In addition, in the present embodiment, owing to be that benchmark is driving anchor 70 liftings with platform 40, so can make the driving amount of cylinder 47,48,49 fewer, and can do one's utmost to suppress the generation of particulate.
In addition, in the present embodiment, in the processing of the drying under reduced pressure of the substrate G2 that for example forms 3 finished product districts, can also carry out following action.
For example, the change that is accompanied by the decompression degree in the container is big, and the substrate that diminishes that promptly is accompanied by pressure has the tendency that produces deflection downwards.At substrate is when forming 3 finished product district substrates, the central portion of substrate have with for example not the anchor 70b of support substrate dock possible.This example can not have platform 40 grades only to come with pin to see in the situation of support substrate.When anchor 70b docks with substrate, just stayed the transfer printing vestige of this anchor 70b in the product region of substrate.But the pressure that is accompanied by in the container diminishes, if the position step-down of the anchor 70b that is not supporting substrate, just can not dock.
In addition, as shown in figure 11, when substrate was 5 finished product districts of formation, the anchor that other are set was just passable with cylinder 59.In this case, cylinder 59 makes anchor 70d lifting, can support for example to form 3 the finished product districts in the finished product district in 5 finished product districts and the interval in 2 finished product districts, that is to say, 2/5ths position of longitudinal direction that can support substrate.By such structure, just can change anchor aptly corresponding to the difference of the substrate that forms 2 finished product districts, 3 finished product districts of formation, 5 finished product districts of formation, can prevent the transfer printing of anchor.In addition, also with to form 5 finished product districts same, support just passable in the situation of horizontal 7 chamferings at 3/7ths position configuration anchors of the longitudinal direction of substrate.Even form the situation in 3 finished product districts, also can be at 1/3rd position configuration anchors with respect to a side of the longitudinal direction of the asymmetrical substrate of center line of substrate.So, when the formation quantity of horizontal finished product is odd number, can between all product region, not dispose anchor yet, and be that the asymmetric and position beyond the product region of part disposes anchor at center line at least linearlyly with respect to substrate.By configuration in this wise, can reduce the quantity of anchor.Just can simplification device owing to follow in this quantity that has reduced movable part, and then can improve the reliability of device.In addition, when horizontal finished product district formation quantity is even number, just on the center line of substrate, dispose at least can, similarly, can reduce the quantity of anchor.
Next, describe at other execution modes of the present invention.Figure 12 is the plane graph of the plate in the unit of the related heat treatment of this mode of expression system, and Figure 13 is its profile of expression.For example can be used in the unit or the adhesion unit (AD) of the heat treatment system of above-mentioned prebake unit (PREBAKE), cooling unit (COL) etc.
Plate 65 is used to put substrate, for example is hot plate spare and cold drawing spare etc.On this plate 65, form a plurality of slotted hole 65a.In slotted hole 65a, holding anchor 170a, 170b, 170c, the bottom 85,86,87 of these anchors 170a, 170b, 170c below plate 65, pushes with push part 71,72,73 respectively.Push part 71 and 73 be that interval corresponding to anchor 170a and 170c is provided with at interval.Push part 71 and 73 and each bottom 85 of anchor 170a and 170c and 87 when opposed, push part 72 is staggered to be disposed, so that not opposed with the bottom 86 of anchor 170b.Push part 71,72,73 links by binding parts 69 and is fixing under such configuration relation.
These binding parts 69 are connected and slide with on the cylinder 67, and this cylinder 67 constitutes these binding parts are slided in the horizontal direction.Sliding is fixed on the plate member 66 with cylinder 67, and this plate member 66 is connected to also can lifting on the plate member usefulness cylinder 68.
