In this coating developing system, for example, edge cleaning portion unit (ER) 44 for coating handling part 24 can adopt the present invention.Below, based on Fig. 3～Figure 17, the form of implementation that applies the present invention to cleaning unit, edge (ER) 44 is described.
Fig. 3 and Fig. 4 represent to be coated with photoresist coater unit (CT) 40 in the handling part 12, the structure of the major part of drying under reduced pressure unit (VD) 42 and cleaning unit, edge (ER) 44.
These coating system processing unit groups (CT) 40, (VD) 42, (ER) 44 on supporting station 60 arranged in order according to treatment process become a line.Lay pair of guide rails 62,62 in the both sides of supporting station 60, utilize along two guide rails, 62,62 parallel one or more groups mobile carrying arms 64,64 direct between the unit (without the main Handling device 54 of main carrying path 52 sides) exchange substrate G.
Photoresist coater unit (CT) 40 comprises: the container handling 66 of the cup-shaped of upper surface open, the liftable workbench 68 that the substrate of mounting maintenance flatly G uses in this container handling 66, be arranged on the lifting drive division 70 of the bottom of container handling 66 in order to make these workbench 68 liftings, the photoresist nozzle 72 that the photoresist that will drip from the substrate G on the last direction workbench 68 is used is along the nozzle scan mechanism 74 of XY direction driving, out-of-operation photoresist nozzle 72 is keeped in repair the nozzle maintenance department 76 of usefulness in the outside of container handling 66, control the controller (not illustrating among the figure) of each one.Nozzle maintenance department 76 comprises nozzle cleaning portion 78 and nozzle standby portion 80.
Drying under reduced pressure unit (VD) 42 has the lower chamber 90 of the pallet or the container type of the shallow end of upper surface open, can hermetic be adjacent to or be fitted to the upper chamber 92 of the lid shape that the upper surface ground of this lower chamber 90 constitutes.Lower chamber 90 is essentially square, and the workbench 94 that configuration level ground mounting supporting substrates G uses on central part is provided with exhaust outlet 96 on four jiaos of bottom surface.The blast pipe 98 that is connected on each exhaust outlet 96 from the bottom of lower chamber 90 leads on the vacuum pump (not shown).Under the state that upper chamber 92 is layed onto on the lower chamber 90, with this vacuum pump with the specified vacuum degree that reduces pressure of the processing space between two chambers 90,92.
On cleaning unit, edge (ER) 44, the workbench 100 that for example is made of aluminium sheet with the horizontal mounting of substrate G is set, the correcting mechanism 102 according to first embodiment that substrate G is located on workbench 100 is removed four cleanings 104 of unnecessary photoresist etc. from the circumference (edge) on four limits of substrate G.Correcting mechanism 102 is navigating to substrate G on the position of setting on the workbench 100, and under the fixing state that keeps with flat-hand position, each cleaning 104 one side move along each limit of substrate G, and one side is removed the unnecessary photoresist dissolving on the circumference on each limit of attaching substrates with solvent, for example diluent.
The correcting mechanism 102 of this first embodiment is in the ground configuration of a pair of diagonal institute direction upper surface opposite of workbench 100, and having can be along a pair of pushing portion 106,106 that equidirectional moves.As shown in Figure 3, two pushing portions 106,106 have leading section end effector of flare up right angle (90 °) basically in horizontal plane.With substrate G on workbench 100 during contraposition, for two end effectors on the corner part of the subtend that is engaged to substrate G on the diagonal of substrate G from both sides with fitting together perfectly, two pushing portions 106,106 move to the position of the outside motion of regulation respectively to the center of workbench 100 from position of readiness.
And then, as shown in Figure 5, correcting mechanism 102 has the interval that separates regulation and is configured in a plurality of fulcrum posts 108 that substrate G horizontal supporting is used on the workbench 100 dispersedly, makes substrate G float the portion of floating 110 of usefulness in fact from fulcrum post 108, and the absorption fixed part 112 that utilizes vacuum suction fixing base G to use.In illustrated embodiment, the direction that the row of the row of the fulcrum post 108 and the portion 110 of floating and absorption fixed part 112 follow alternately disposes.
As shown in Figure 6, fulcrum post 108 extends or outstanding to vertical top from the upper end central part that is fixedly installed to the tubular supporting mass 114 on the workbench 100, is born the lower surface of substrate G by the front end of pin.Float portion 110 and comprise the gas ejection portion 116 of the trumpet type that extends upward from the upper end circumference of tubular supporting mass 114, and be connected to gases at high pressure source of supply (not shown) in this gas ejection portion 116 via ventilating path 114a in the tubular supporting mass 114 and feed tube 118.The open and close valve (not shown) that opening/closing control usefulness is set midway in feed tube 118.The upper end of gas ejection portion 116 can be set in and mounting on the position of the height that forms small gap g between the back side of the substrate G on the fulcrum post 108 (lower surface).
As shown in Figure 7, in substrate G mounting under the state on the workbench 100, will be from the next gases at high pressure of above-mentioned gases at high pressure source of supply, air (also can be nitrogen etc.) for example, via the ventilating path 114a in feed tube 118 and the tubular supporting mass 114 from gas ejection portion 116 with the pressure of offsetting regulation, when being the gravity of substrate G or the pressure ejection that surpasses it, substrate G floats in fact from fulcrum post 108.Because gas ejection portion 116 forms trumpet type, so the air of running into the lower surface of substrate G can not produce eddy current, discharges by gap g smoothly.
The material of fulcrum post 108, owing to can very strong mutual friction mutually not take place with substrate G basically, so, can be the high arbitrary substance of physical strength, but preferably with respect to low rubber of substrate G coefficient of friction or resin etc.The float gas ejection portion 116 of portion 110 also can be a material arbitrarily, even but preferably contact with substrate G can be with the flexible material of its injury by flexible bending, for example rubber, cloth, engineering plastics etc.
As shown in Figure 5, absorption fixed part 112 is made of the cylindrical body that is installed in the upper surface of workbench 100 with the height substantially the same with fulcrum post 108 vertically upward, is connected on vacuum source, for example vacuum pump or the ejector (not shown) via the air intake duct (not shown) at the back side of workbench 100.With substrate G mounting under the state on the workbench 100, when the open and close valve (not shown) of the opening/closing control usefulness midway that will be located at this air intake duct is opened, will adsorb fixed part 112 and is connected on the vacuum source, utilize vacuum adsorption force that substrate G absorption is remained to and adsorb on the fixed part 112.In addition, the upper end that preferably contacts with substrate G at least of material of absorption fixed part 112 is not easy to injure the rubber of substrate and resin etc.
Here, the mass action to the correcting mechanism in the present embodiment 102 describes.As mentioned above, will be with photic resist-coating unit (CT) 40 painting photoresist liquid, accept to be transported into the edge by carrying arm 64,64 then and clear up unit (ER) 44, on the workbench 101 more correctly essentially horizontally on mounting and the fulcrum post 108 with the substrate G that drying under reduced pressure unit (VD) 42 carried out dried.When this substrate was transported into, float portion 110 and absorption fixed part 112 were in non-action status.
After substrate was transported into, at first, portion's 110 actions of floating as mentioned above, from gas ejection portion 116 ejection pressure-airs, utilized the pressure of air that substrate G is floated in fact from fulcrum post 108.Under the state that like this substrate G is floated, 106,106 actions of pushing portion, as mentioned above, two end effectors move on the corner part that is engaged to both sides in a pair of diagonal of substrate G always with fitting together perfectly, in this moving process, the position of substrate G is finely tuned in the XY direction, navigate on the desired location on the workbench 100.
When carrying out this contraposition, substrate G can be unsettled fully, also can contact gently with part or all fulcrum post 108.Since utilize the pressure of air that the gravity of substrate G is almost offset, even the lower surface of substrate G contacts also and can slide smoothly with fulcrum post 108, so, can not damage and scratch, can not pollute.In addition, near the substrate G of suspended state is higher than pin at least partly each fulcrum post 108 front end gets final product, between the pin 108,108 of adjacency and substrate circumference deflection downwards and be lower than the height and position of the front end of pin.
After the contraposition of aforesaid substrate G finished, the portion 110 of floating disconnected, and stops the ejection of pressure-air.Then, replace the portion of floating.112 actions of absorption fixed part are worked vacuum adsorption force, and substrate G is fixedly remained on desired location with flat-hand position.Pushing portion 106,106 is in this stage, and perhaps substrate G is left after just having finished in location in front, keeps out of the way position of readiness.
Like this, utilize correcting mechanism 102 that substrate G is navigated to desired location on workbench 100, and keep so that flat-hand position is fixing.In this state, as mentioned above, cleaning 104 action are removed unnecessary photoresist from the circumference of substrate G.After this edge cleans end, in correcting mechanism 102, will adsorb fixed part 112 and close, remove vacuum adsorption force.Afterwards, carrying arm 64,64 or other carrying mechanism transport the substrate G that disposes from workbench 100, are transported to back operation handling part.
As mentioned above, in the correcting mechanism 102 of present embodiment, when on workbench 100, utilizing pushing portion 106,106 mechanically to carry out the contraposition of XY direction, substrate G is become the state that floats in fact from the fulcrum post 108 by the portion of floating 100, can not make injury and scratch to the lower surface of substrate G, and can not pollute yet, can be along on the desired location of sliding and accurately substrate G being positioned on the workbench 100.And then, since the gas ejection portion 116 of the portion 110 of floating with the mode of surrounding fulcrum post 108 be arranged on fulcrum post 108 near, so, can substrate G be floated from fulcrum post 108, can reduce the consumption of gases at high pressure as much as possible.
In addition, in the cleaning unit, edge (ER) 44 of present embodiment, since can utilize correcting mechanism 102 with substrate G safety, correctly, contraposition promptly is on the desired location on the workbench 100, so, can utilize the circumference on each limit of cleaning 104 couples of substrate G to carry out safety, high accuracy and the cleaning of high efficiency edge.
Secondly, based on the calibration substrate 102 of Fig. 8～Figure 13 explanation according to second embodiment.The correcting mechanism 102 of this second embodiment for example also can be applied to the cleaning unit, edge (ER) 44 of present embodiment, has the pushing portion 106 (Fig. 3, Fig. 4) the same with above-mentioned first embodiment.
As shown in Figure 8, in the present embodiment, the interval that on workbench 100, separates regulation dispersedly, for example with latticed configuration pattern arrangement double as support and float portion and the fixing jut 120 for example cylindraceous of absorption.
This jut 120 is as Fig. 9, Figure 11, shown in Figure 13, bottom cylinder 122 with the upper surface that is fixedly installed to workbench 100, and via trumpet type gas channeling portion 124 on the top of bottom cylinder 122 direction and the horizontal direction top cylinder portion 126 of installing with displacement up and down.The flange shape bottom 124a that forms on the inwall of bottom cylinder 122 gas channeling portion 124 embeds the fixedly slot part 122a of the ring-type of usefulness, and the trumpet type upper end 124b that forms on the inwall of top cylinder body 126 gas channeling portion 124 embeds the fixedly ring-type slot part 126a of usefulness.The bottom of gas channeling portion 124 is connected on the flue 128 that runs through workbench 100.
The material of bottom cylinder 122 can be the high any member of physical strength.The material of top cylinder body 126 is owing to directly contact with the lower surface of substrate G, so be preferably the rubber that can not injure substrate G or resin etc.The material of gas channeling portion 124 is preferably flexible rubber or cloth etc.
As Figure 10 and shown in Figure 12, the flue 128 that is connected on the jut 120 (gas channeling portion 124 more correctly says so) is communicated with gases at high pressure source of supply 134 and vacuum source 136 via the open and close valve 130 of opening/closing control usefulness and the dibit pattern triple valve 132 of stream switching usefulness.Open and close valve 130 and triple valve 132 for example are made of electromagnetically operated valve, the open/close position of control part 138 control open and close valves 130 and the switching position of triple valve 132.In addition, in gases at high pressure source of supply 134 and vacuum source 136, include the pressure control device (not shown) respectively.
In substrate G mounting under the state on the workbench 100, as shown in figure 10, when open and close valve 130 being switched to the locational while of opening, when triple valve 132 is switched to gases at high pressure source of supply 134 1 sides, be supplied to gas channeling portion 124 in each cylinder 120 via flue 128 from the gases at high pressure of gases at high pressure source of supply 134, for example air (also can be nitrogen etc.).Whereby, as shown in figure 11, gas channeling portion 124 plays a part ejection portion, and vertically upward gases at high pressure are blown on the lower surface of substrate G.By with the pressure that makes this air vertically upward the counteract gravity forces of substrate G or the mode that surpasses this gravity being set the air pressure of gases at high pressure source of supply 134 1 sides, substrate G can float from the upper surface of top cylinder body 126.At this moment, the air that sprays vertically upward from gas channeling portion 124 by being formed on substrate G lower surface and the gap g between the upper surface of top cylinder body 126 discharge.In addition, as shown in figure 11, the pressure of gas channeling portion 124 quilts air vertically upward stretches upward, and top cylinder body 126 becomes from the state of bottom cylinder 122 come-ups.
In the present embodiment, same, at float state, the lower surface of substrate G also can contact lightly with the upper surface of top cylinder body 126.In this case, when because the pushing force of the horizontal direction that pushing portion 106,106 produces, substrate G is to the horizontal direction displacement or when mobile, because top cylinder body 126 is bearing in the flexible gas channeling portion 124, so, can imitate moving of substrate G to identical direction displacement.Therefore, can not damage and scratch substrate G.Thereby, can be safely, rapidly, correctly substrate G is navigated on the desired location of workbench 100.
