Embodiment
Below, best form of implementation of the present invention is described in conjunction with Fig. 1 to Fig. 7.
Fig. 1 illustrates an example of the form of implementation of the 1st scheme, is the end view that one of the transfer roller of one of the inscape to substrate board treatment, for example development processing apparatus is showed with the broken section form.General structure for development processing apparatus, be described in conjunction with Fig. 8, therefore its explanation is omitted, but transfer roller 10 shown in Figure 1, be corresponding to the transfer roller 4b's of the middle part that is configured in treatment trough 2 among a plurality of transfer roller 4a~4b of development processing apparatus shown in Figure 8.
Transfer roller 10 is that the whole width of lower surface of its outer peripheral face and substrate 1 is contacted cylindrical.This transfer roller 10, support substrate 1 also transmits, thereby but also has the function that the whole width contact edge rotation of the lower surface of limit and substrate 1 is cleaned the lower surface of substrate.Under transfer roller 10, dispose liquid storing barrel 12.In liquid storing barrel 12, accommodate the moistening liquid of use of supplying with by giving pump 15 from the feed flow source, this is moistening is for example that surface from substrate 1 flows to downwards bottom treatment trough and is recycled to the developer solution 14 of sending by giving pump 15 from recycling can after recycling can (not shown) with liquid.Supply with continuously developer solution in liquid storing barrel 12, make to be in all the time the state that is full of developer solution 14 in liquid storing barrel 12, the developer solution that overflows from the top of liquid storing barrel 12 is through recycling use.And the part outer peripheral face of transfer roller 10 is immersed in the developer solution 14 that is full of liquid storing barrel 12.
As the device with structure shown in Figure 1, the part outer peripheral face of transfer roller 10 is immersed in the developer solution 14 that is full of liquid storing barrel 12, and therefore, the outer peripheral face of transfer roller 10 is in the wetting state of liquid 14 that is developed all the time.Therefore, trickle down and be attached on the outer peripheral face of transfer roller 10 from the surface of substrate 1 even contain the developer solution of resist, also the developer solution exhaustion can not occur and the phenomenon of resist composition curing on the outer peripheral face of transfer roller 10.Therefore, needn't worry that the resist that transfer roller 10 can be cured pollutes.In addition, because transfer roller 10 in the developer solution 14 that is full of liquid storing barrel 12 just is immersed in wherein, thereby needn't worry that developer solution splashes.Therefore, can not be attached to and pollute substrate 1 on substrate 1 owing to splashing the developer solution that causes containing resist, perhaps contain resist development liquid and be attached on sensor equipment and cause misoperation.
Secondly, Fig. 2 illustrates an example of the form of implementation of the 2nd scheme, the end view that one of transfer roller that is one of the inscape to development processing apparatus is showed.This transfer roller shown in Figure 2 16 is corresponding near the most transfer roller 4a that accounts among a plurality of transfer roller 4a~4c of development processing apparatus shown in Figure 8, transfer roller 4b, the 4c middle part that is configured in respectively treatment trough 2 and port of export opening 3b.
Transfer roller 16 is circular plate shape, perhaps is fixed with a pair ofly at the two ends of rotation fulcrum 18, perhaps is fixed with on fulcrum 18 a plurality ofly in rotation, is for example that two ends and the central part at rotation fulcrum 18 is fixed with 3.And, below near the height and position of this transfer roller 16 and the substrate 1 supported than transfer roller 16, dispose outlet 22 and transfer roller 16 discharge liquid ejection nozzle 20 in opposite directions.For discharging liquid ejection nozzle 20, same with Fig. 1, will for example flow to the treatment trough bottom downwards from the surface of substrate 1 and be recycled to developer solution in recycling can, supply with by giving pump from recycling can.At this moment, must be lower to discharging the pressure setting that liquid ejection nozzle 20 supplies with developer solutions, the low developer solutions 14 to 16 discharges from outlet 22 to transfer roller of this pressure can not splash and the degree of dispersing everywhere.
Discharging developer solution 14 for the outlet 22 of discharging liquid ejection nozzle 20 to transfer roller 16 controls like this, namely, during process on transmission substrate 1 limit, limit, do not contact with the lower surface of substrate 1 at transfer roller 16, and when also being present near this transfer roller 16, substrate 1 do not discharge, and when transfer roller 16 contacts with the lower surface of substrate 1 and substrate 1 be present near the time, discharge the outlet 22 of liquid ejection nozzle 20 and do not discharge developer solution.By the intermittent developer solution of discharging as mentioned above, make the occasion that is cycled to repeat use at the developer solution that contains resist, can avoid being attached on substrate 1 and polluting substrate 1 from contain resist development liquid or its spittle that the outlet 22 of discharging liquid ejection nozzle 20 is discharged.On the other hand, during not transmitting substrate 1, discharging the outlet 22 of liquid ejection nozzle 20 and discharge developer solution 14 to transfer roller 16, is that intermittence is carried out at regular intervals.Intermittently carry out at regular intervals by the discharge that makes as mentioned above developer solution, thereby not only can make transfer roller 16 keep wetting state to prevent that the resist composition from solidifying during the processing of not carrying out substrate 1, but also can reduce the use amount of developer solution.
As the device with structure shown in Figure 2, by discharging developer solution 14 by the outlet 22 of discharging liquid ejection nozzle 20 to transfer roller 16, make transfer roller 16 be in all the time and be developed the wetting state of liquid 14.Therefore, trickle down and be attached on transfer roller 16 from the surface of substrate 1 even for example contain the developer solution of resist, developer solution also can be exhausted, can avoid resist to solidify.Therefore, can prevent that the resist that transfer roller 16 is cured from polluting.In addition, because developer solution 14 is discharged from outlet 22 low pressure of discharging liquid ejection nozzle 20, and be to discharge developer solutions 14 from the position near transfer roller 16 to transfer roller 16, therefore, developer solution 14 is not easy to splash, and developer solution 14 disperses in can be not on a large scale everywhere.Therefore, even if be cycled to repeat the occasion of use at the developer solution that contains resist, yet can not splash the pollution that causes substrate 1 or be attached on sensor equipment and cause misoperation because containing resist development liquid.In addition, discharging liquid ejection nozzle 20 is the belows that are configured in the height and position of substrate 1, therefore, even contain resist development liquid from outlet 22 drippages, needn't worry that also this developer solution can be attached on substrate 1.
In addition, Fig. 3 is the end view of transfer roller that another form of implementation of the 2nd scheme is showed.In form of implementation shown in Figure 3, discharge the outlet 22 of liquid ejection nozzle 20 towards oblique below.If as form of implementation shown in Figure 2, will discharge liquid ejection nozzle 20 and be arranged to outlet 22 up, when ending outlet 22 discharge liquid, needn't worry that liquid can be from outlet 22 drippages, and with respect to this, in form of implementation shown in Figure 3, liquid might be from outlet 22 drippages.But, are the belows that are configured in the height and position of substrate 1 shown in double dot dash line L owing to discharging liquid ejection nozzle 20, therefore needn't worry containing resist development liquid and can be attached on substrate 1 from outlet 22 drippages.
Secondly, Fig. 4 illustrates an example of the form of implementation of the 3rd scheme, is the transfer roller of one of the inscape to development processing apparatus and the end view showed except the liquid roller.This transfer roller shown in Figure 4 24 is corresponding near the transfer roller 4c among a plurality of transfer roller 4a~4c of development processing apparatus shown in Figure 8, port of export opening 3b that be configured in treatment trough 2.
Be configured to directly over transfer roller 24 with transfer roller 24 in opposite directions except (rolling) liquid roller 26, be its outer peripheral face contact with the whole width of the upper surface of substrate 1 cylindrical, the whole width contact edge rotation of the upper surface of the substrate 1 that limit and transfer roller 24 are supported and transmitted, thus the function that the developer solution with crossing that covers on substrate 1 is removed from substrate 1 had.And near the below of the height and position (representing with double dot dash line L in Fig. 4) of substrate 1 transfer roller 24, that transfer roller 24 is supported and transmitted disposes outlet 30 and removes liquid roller 26 discharge liquid ejection nozzle 28 in opposite directions.Discharge liquid ejection nozzle 28 for this, same with discharge liquid ejection nozzle 20 shown in Figure 2, the developer solution that for example flows to the treatment trough bottom downwards from the surface of substrate 1 and be recycled in recycling can is supplied with by giving pump from recycling can.At this moment, the pressure setting when supplying with developer solution to discharge liquid ejection nozzle 28 must be lower, the low degree of dispersing everywhere to not splashing from outlet 30 to the developer solution 14 of discharging except liquid roller 26 of this pressure.
For the outlet 30 of discharging liquid ejection nozzle 28 to discharge the control of developer solutions 14 except liquid roller 26, same with discharge liquid ejection nozzle 20 shown in Figure 2, during process on transmission substrate 1 limit, limit, do not contact with substrate 1 at transfer roller 24 and except liquid roller 26, and when also being present near this transfer roller 24, substrate 1 do not discharge, and when contacting with substrate 1 at transfer roller 24 and except liquid roller 26 and substrate 1 be present near the time, the outlet 30 of discharge liquid ejection nozzle 28 is not discharged developer solution.In addition, during not transmitting substrate 1, discharging the outlet 30 of liquid ejection nozzle 28 to discharging developer solution 14 except liquid roller 26, is intermittently to carry out at regular intervals.
As the device with structure shown in Figure 4, due to from the outlet 30 of discharging liquid ejection nozzle 28 to discharging developer solutions 14 except liquid roller 26, make to be in all the time the state that is developed liquid wetting except liquid roller 26.In addition, be discharged to except the developer solution 14 on liquid roller 26 outer peripheral faces, flow on the outer peripheral face of the transfer roller 24 that is positioned at the below downwards via the outer peripheral face except liquid roller 26, thereby make transfer roller 24 also be in all the time the state that is developed liquid wetting.Therefore, even what contact with the upper surface of substrate 1 has adhered to except on liquid roller 26 developer solution that for example contains resist, and be attached on transfer roller 24 from the unrestrained resist development liquid that contains in the surface of substrate 1, developer solution can be inexhausted yet, can prevent that the resist composition from solidifying.Therefore, can prevent that the resist that is cured except liquid roller 26 and transfer roller 24 from polluting.In addition, because developer solution 14 is discharged from outlet 30 low pressure of discharging liquid ejection nozzle 28, and be near position from transfer roller 24 to discharging developer solutions 14 except liquid roller 26, therefore, developer solution 14 is not easy to splash, developer solution 14 disperses in can be not on a large scale everywhere.Therefore, even if be cycled to repeat the occasion of use at the developer solution that contains resist, can not occur to splash and pollute substrate 1 or be attached to phenomenons such as causing misoperation on sensor equipment because containing resist development liquid yet.In addition, discharge liquid ejection nozzle 28 is configured in the height and position below than substrate 1, therefore, even contain resist development liquid from outlet 30 drippages, needn't worry that also this developer solution can be attached on substrate 1.
Fig. 5 and Fig. 6 illustrate the modified example of the 3rd scheme, and Fig. 5 is that the transfer roller of one of inscape to development processing apparatus reaches the sectional side view of being showed except the liquid roller, and Fig. 6 is its front view.This Fig. 5 and transfer roller shown in Figure 6 60 and except liquid roller 52,54, displaying be near the transfer roller 4c that configures the port of export opening 3b of the treatment trough 2 of development processing apparatus shown in Figure 8 and near roller.
The development processing apparatus that this modified example is related, transmit substrate 1 in the cardinal principle in treatment trough 2 whole zone with horizontal attitude, and send to next process after making substrate 1 become lateral attitude near the downstream for the treatment of trough 2.Therefore, the zone at (namely near port of export opening 3b place), the transfer roller 62 that substrate 1 is fixed in treatment trough 2 transmits with horizontal attitude near the downstream for the treatment of trough 2.And in zone in addition, namely near the zone of port of export opening 3b, substrate 1 is transmitted roller 60 and removes liquid roller 52,54 and transmit.Except liquid roller 52,54, be arranged in and form the minim gap that substrate 1 can therefrom pass through between them.Transfer roller 60 reaches except liquid roller 52,54, is arranged on roller installing component 64,66.Roller installing component 64,66 as shown in Figure 6, can be under the driving of not shown drive source, take from except the point 0 on the extended line of the rotating shaft 68 of liquid roller 52 through and the straight line parallel with the substrate direction of transfer (Fig. 6 for through point 0 and perpendicular to the straight line of paper) centered by, the set angle of direction rotation (single-point rule A and A ' angle) up and down.
Be positioned at roller installing component 64,66 under the state of lower position, as shown in the solid line in Fig. 5 (a) and Fig. 6, transfer roller 60 and being horizontal except liquid roller 52,54.And, on this horizontal level except between liquid roller 52 and adjacent transfer roller 60, be provided with the oscillator 72 whether detection substrate 1 is sent to the checkout gear 70 on transfer roller 60.In the downstream of oscillator 72, be provided with to the discharge liquid ejection nozzle 74 except liquid roller 54 discharge developer solutions that is positioned at horizontal level.Discharge liquid ejection nozzle 74, be arranged to horizontal level substantially on parallel ejection nozzle pipe 75, be provided with a plurality of along the depth direction of pointing to Fig. 5 paper except liquid roller 54.For this ejection nozzle pipe 75, same with discharge liquid ejection nozzle 20 shown in Figure 2, the developer solution that for example flows to the treatment trough bottom downwards from the surface of substrate 1 and be recycled in recycling can is supplied with by giving pump from recycling can.Checkout gear 70 and ejection nozzle pipe 75 are fixed on treatment trough 2.In addition, among the transfer roller 60 that is arranged on roller installing component 64,66 between the transfer roller 60 and transfer roller 62 of upstream side, also be provided with the checkout gear 76 that detects substrate 1.
Be positioned at roller installing component 64,66 under the state of uppermost position, as shown in the double dot dash line in Fig. 5 (b) and Fig. 6, transfer roller 60 and tilting as low side to put 0 one sides except liquid roller 52,54, and, this transfer roller 60 and except liquid roller 52,54 its extreme lower positions will be higher than ejection nozzle pipe 75.In Fig. 5 (b), do not draw the tilt condition of roller on the depth direction.
The operation principle of this development processing apparatus is as described below.In development processing apparatus, substrate 1 is sent into from arrival end opening (not shown Fig. 5) the one-tenth horizontal attitude for the treatment of trough 2, the developer solution that developer solution ejection nozzle 5 is discharged covers on substrate 1, and the limit keeps horizontal attitude to send to downstream under transfer roller 62 drives carrying out the development treatment limit under this state.At this moment, roller installing component 64,66 is positioned at lower position, transfer roller 60 and be positioned at horizontal level except liquid roller 52,54.And, there is this moment developer solution to discharge from discharging liquid ejection nozzle 74, the developer solution of discharge is discharged to except on liquid roller 54, keeps being developed the state of liquid wetting except liquid roller 54.In addition, be positioned at except liquid roller 54 belows except liquid roller 52, also be in by the wetting state of developer solution from flowing down except liquid roller 54.Therefore, can be because not solidifying except liquid roller 52, the 54 dry resist compositions that cause.
Afterwards, send and when making oscillator 78 action of checkout gear 76, stop discharging developer solutions from discharging liquid ejection nozzle 74 when substrate 1.This is to discharge liquid ejection nozzle 74 because, substrate 1 has approached, if developer solution continues to discharge from discharging liquid ejection nozzle 74, the spittle of the developer solution that might discharge is splashed on substrate 1 and produces and process the bad phenomenon such as irregular.Afterwards, when making oscillator 72 action of checkout gear 76 when further transmission substrate 1, the rotation of transfer roller 60 stops, and substrate 1 will stop on transfer roller 60.Afterwards, make aforementioned drive source work, roller installing component 64,66 rises and makes transfer roller 60 tilt take its point 0 one sides as low side, and the substrate 1 that is placed on above it also becomes lateral attitude.So the developer solution major part that covers on substrate 1 is trickled downwards and basically is removed.Then, after most of liquid flows down, again drive transfer roller 60 and except liquid roller 52,54 rotations, make it to keep lateral attitude to transmit downstream substrate 1, the port of export opening 3b that forms adaptably from the position with this lateral attitude sends and is sent to next process.At this moment, because roller installing component 64,66 rises, the oscillator 72 of discharge liquid ejection nozzle 74 and checkout gear 70 etc. is positioned at the below of transfer roller 60, thereby can not hinder the transmission of substrate 1, and, even liquid spills from discharging liquid ejection nozzle 74 unintentionally, can not be attached on substrate 1 yet.After substrate 1 was sent from port of export opening 3b, roller installing component 64,66 descended to wait for next substrate.
In addition, Fig. 7 illustrates an example of the form of implementation of the 4th scheme, is the cutaway view that the bottom of the treatment trough of the inscape of development processing apparatus is showed.In device shown in Figure 7, the top at the incline direction of the inner bottom surface 34 of the inclination for the treatment of trough 32 disposes outlet 38 towards the discharge liquid ejection nozzle 36 of inner bottom surface 34.Discharge liquid ejection nozzle 36 for this, with for example flowing to the treatment trough bottom downwards from the surface of substrate 1 and being recycled to developer solution in recycling can, supply with from recycling can.
As the device with structure shown in Figure 7, discharge developer solution 14 from the outlet 38 of discharging liquid ejection nozzle 36 to the top of the incline direction of the inner bottom surface 34 for the treatment of trough 32, the developer solution 14 of this discharge flows downward on inner bottom surface 34 along the gradient of inner bottom surface 34.Therefore, whole inner bottom surface 34 is in the wetting state of liquid 14 that is developed all the time.Therefore, even the developer solution that contains resist is unrestrained on inner bottom surface 34 from the surface of substrate 1, this developer solution also can be exhausted, thereby resist can not solidify, and can prevent that the resist that the inner bottom surface 34 for the treatment of trough 32 is cured from polluting.
Abovely be illustrated with regard to development processing apparatus, but the present invention also can be applied to carry out the substrate board treatment processed such as cleaning, burn into striping etc.
