In addition, side face at nozzle 71a, 71b is formed with a plurality of supply port 72a, 72b respectively along Y direction devices spaced apart, and, directions X adjacent nozzles 71a each other, 71b each other, 71a and 71b each other, the modes different with the Y width position form.Thus, can roughly on whole, cool off the substrate G that utilizes 5 conveyances of rolling transport mechanism equably.
(Fig. 5 is the figure that is used to illustrate the type of cooling of the rolling member 50b that is arranged on the substrate cooling apparatus) as shown in Figure 5, be configured in the rolling member 50b in the main cooling chamber 65b, has the not shown stream that connects Y direction (direction of principal axis) respectively in inside, simultaneously, Y direction both ends are connected with the pipe arrangement 52 with cooler (chiller) 51 across swivel coupling, make cooling fluid in the pipe arrangement 52 that utilizes cooler 51 to be adjusted to set point of temperature, for example cooling water at internal circulation.Thus, rolling member 50b is cooled to the temperature of regulation respectively, performance is as the effect of the part of the cooling body 7 of cooling base G when contacting with substrate G.In addition, at the adjacent rolling member 50b of directions X each other, the circulating direction of cooling water becomes reverse (reference arrow direction), thus, can utilize whole evenly coolings of the substrate G of rolling transport mechanism 5 conveyances.In addition, the symbol among the figure 53,54 is respectively and is used to make the pump that cooling water circulates and is used to adjust the valve that is sent to the flow of the cooling water in the rolling member 50b in the pipe arrangement 52 in pipe arrangement 52 and rolling member 50b.The temperature of substrate G is as requested utilized the temperature of the cooling water of the flow of cooling water of cell controller 104 control pumps 53, valve 54 and cooler 51, i.e. the temperature of rolling member 50b.
Be configured in the preparation cooling chamber 65a rolling member 50a at least outer peripheral face form by low heat conductivity materials such as resins, substrate G is not caused thermal impact.
The upper wall portions and the bottom wall portion of housing 6 have double-wall structure, and this double wall comprises inwall 66 and the outer wall 67 that is spaced from each other the space setting.On inwall 66, be provided with a plurality of for example netted exhaust outlet 68a that extend along the Y direction along the directions X devices spaced apart; Simultaneously, on outer wall 67, be provided with exhaust outlet 68b; In the space between inwall 66 and outer wall 67, be provided with the exhaust line 68c that is communicated with a plurality of exhaust outlet 68a and exhaust outlet 68b.Exhaust outlet 68a, exhaust outlet 68b and exhaust line 68c are configured for discharging the exhaust portion of gas in the housing 6.In addition, in the time of only can obtaining sufficient exhaust effect, can exhaust portion be set yet,,, preferably be connected with exhaust source 68d such as ventilation fan in order to increase exhaust effect when when upper wall portions is provided with exhaust portion in upper wall portions by the exhaust portion that is located at bottom wall portion.
Below, describe at the cooling processing of the substrate G in the cooling unit (COL) 25 that constitutes as mentioned above.
Fig. 6 is the figure that is used for illustrating in the substrate cooling processing of substrate cooling apparatus.
In the cooling unit (COL) 25, in adhesion unit (AD) 24 (cooling unit) (COL) in 29,32, utilize substrate G after the heating of transport mechanism conveyance of heat treated unit (HT) 28,31 sides by moving into mouthfuls 61 respectively, will be passed to rolling transport mechanism 5, utilize rolling transport mechanism 5 to carry out conveyance on one side, housing 6 in utilize cooling body 7 to cool off on one side.Therefore, owing to carry out the conveyance and the cooling of substrate simultaneously, so can realize reduction in processing timeization.
At this moment, at first, substrate G is cooled to about normal temperature by supplying with gas at normal temperature from nozzle 71a in preparation cooling chamber 65a, removes heat (with reference to Fig. 6 (a)) roughly.Then, substrate G passes through port 63, in main cooling chamber 65b, because contacting with the air of supplying with ring 71c and with rolling member 50b from nozzle 71b of cell controller 104 control flows and temperature is cooled to the temperature (with reference to Fig. 6 (b)) of regulation.Therefore, can prevent that substrate G from deforming, carry out meticulous cooling simultaneously.In addition, cool off from the two sides side because substrate G, supplies with ring 71c and rolling member 50b by nozzle 71a, 71b, thereby can prevent bending.
In case the substrate G that utilizes 5 conveyances of rolling transport mechanism is by taking out of mouth 62, will be passed to resist coating element (CT) 26 (in cooling unit (COL) 29,32, be respectively interface station 4, inspection unit (IP) 35) transport mechanism of a side, utilize this transport mechanism to carry out conveyance on conveyance circuit A (B).Therefore, the conveyance with the substrate G that cools off front and back during cooling only is the so-called planar flows dynamic formula that utilizes rolling transport mechanism 5 grades, and is as safe as a house.
Below, describe for the variation of preparing cooling end 7a and main cooling end 7b.
Fig. 7 is the figure that expression is arranged on the variation of preparation cooling end 7a in the substrate cooling apparatus and main cooling end 7b.
Shown in Fig. 7 (a), preparation cooling end 7a also can constitute, and is provided with fan filter unit 75, replaces air supply source 73a and nozzle 71a, and this fan filter unit is located at the upper wall portions of preparation cooling chamber 65a, has fan 75a and filter 75b.Fan filter unit 75 sucks the air of for example normal temperature outside the housing 6 by the rotation of fan 75a, utilizes filter 75b to purify, and supplies with to the surface of the substrate G that utilizes 5 conveyances of rolling transport mechanism.Because fan filter unit 75 is generally slim, and does not need external air supply source 73a, therefore, can realize the slimming of housing 6, simultaneously, can control the whole pedestal area (footprint) of reduction means.For example, a plurality of fan filter units 75 are arranged, make in preparation cooling chamber 65a according to size assortment on directions X and Y direction of substrate G, can be to all surfaces air supply of substrate G.
Shown in Fig. 7 (b), main cooling end 7b also can constitute, and is provided with conduit 76, replaces nozzle 71b and supplies with ring 71c, and this conduit is connected with tempering air supply source 73b, is located at the upper wall portions of main cooling chamber 65b.The peristome 76a of conduit 76 forms the mode that diameter enlarges gradually, and making can be to all surfaces air supply of substrate G in main cooling chamber 65b.Further, in this case, conduit 76 preferably will have the diffuser plate 76b of a plurality of supply holes, or filter and fan filter unit (all not shown) etc. are arranged in the peristome 76a, make it possible to all surfaces of substrate G air supply equably.
In addition, the invention is not restricted to above-mentioned execution mode, can carry out various distortion.For example, nozzle 71a and fan filter element 75 can be set also, constitute preparation cooling chamber 65a; Nozzle 71b and conduit 76 also can be set, constitute main cooling chamber 65b.In addition, also can make the same structure that to cool off that constitutes of rolling member 50a with rolling member 50b.
Utilizability on the industry
According to the present invention, be applicable to the situation of glass substrate, particularly large substrate such as FPD, But be not limited to glass substrate, also can be widely used in the heating of other substrates such as semiconductor wafer Process.
