Then, on one side with reference to Fig. 5 on one side in the exposure device with regard to the 1st embodiment used liquid remove device 100 and describe.Liquid remove device 100 be arranged in the way in conveyance path of conveyer H, will be owing to immersion method attached to removing through the P liquid 50 of the substrate after the exposure-processed.In the present embodiment, liquid is removed device 100 and is set between the 2nd carrying device H2 and the 3rd carrying device H3.Liquid is removed device 100 and is had table device 20, is arranged at table device 20, keeps the cradle portion 21 of following central portion of substrate P and the rotating mechanism 22 that the cradle portion (holder) 21 that keeps substrate P is rotated.The vacuum suction hole of a part that keeps vacuum plant is being set on cradle portion 21, and cradle portion 21 absorption keep the following central portion of substrate P.Rotating mechanism 22 is made of the motor that is arranged at table device 20 inside, by making axial region 23 rotations that are connected to cradle portion 21 cradle portion 21 is rotated.And table device 20, cradle portion 21 and rotating mechanism 22 are set at chamber 25 inside as lid shell mechanism, are provided with liquid attracting device (liquid-sucking) 29 via stream 28 in chamber 25.Stream 28 is provided with valve 28A.
Cradle portion 21 liftably is provided with respect to the top of table device 20 with axial region (shaft) 23.When the cradle portion 21 that keeps substrate P rose with respect to table device 20, substrate P left from table device 20, can be rotated by means of the driving of rotating mechanism 22.On the other hand, substrate P is kept by the 2nd cradle portion 24 that is arranged at above the table device 20 when cradle portion 21 descends.
Chamber 25 has the 1st peristome 26 that is formed at the 2nd carrying device H2 side and the 2nd peristome 27 that is formed at the 3rd carrying device H3 side.The 1st peristome 26 is provided with the 1st baffle plate 26A that the 1st peristome 26 is opened and closed, and the 2nd peristome 27 is provided with the 2nd baffle plate 27A that the 2nd peristome 27 is opened and closed.1st, the on-off action of the 2nd baffle plate 26A, 27A is controlled by control device CONT.If the 1st baffle plate 26A can be removed the table device 20 of device 100 via the 1st peristome 26 visit liquid by open then the 2nd carrying device H2.That is, the 2nd carrying device H2 can carry out conveyance (moving into) with the table device 20 that substrate P removes device 100 to liquid via the 1st peristome 26.The 3rd carrying device H3 removes the table device 20 of device 100 via the 2nd peristome 27 addressable liquid.That is, the 3rd carrying device H3 can carry out conveyance (taking out of) with the table device 20 that substrate P removes device 100 to liquid via the 2nd peristome 27.On the other hand, by being closed, the 1st, the 2nd baffle plate 26A, 27A make chamber 25 inner sealings.
Then, utilizing Fig. 1 and Fig. 2 just to possess above-mentioned exposure device body EX and liquid removes the action of the device manufacturing system SYS of device 100 and describes.
In exposure device body EX, the substrate P that is kept on the chip bench PST1 utilizes immersion method to expose, with its parallel substrate P, carry out the detection of alignment mark or the measurement of surface information (AF (automatic focus)/AL (adjusting automatically) information) to being kept on the chip bench PST2.Fig. 1 represents that chip bench PST1 carries out exposure actions in exposure device body (exposure position) EX, and chip bench PST2 measures the situation of action on the measuring position.In the exposure device body, carry out the liquid supply of fluid Supplying apparatus 1 and the liquids recovery of liquid withdrawal system 2, the light path of the exposure light of the image planes side of projection optical system PL is full of with liquid 50.If the exposure-processed of the substrate P that is kept on the chip bench PST1 is finished, then the liquid of stop liquid feedway 1 is supplied with, and carries out liquids recovery by liquid withdrawal system 2.If utilize the liquids recovery of liquid withdrawal system 2 to finish, then chip bench PST1 keeps out of the way from exposure device body EX, and the chip bench PST2 that has finished various measurements simultaneously is placed into exposure device body (exposure position) EX.The substrate P of the exposure-processed that is through with on chip bench PST1 is loaded onto the 2nd carrying device H2 by means of chip bench PST1.The chip bench PST1 of the substrate P unloading after the exposure-processed that is through with accepts unexposed substrate P from the 1st carrying device H1, the various measurements on the beginning measuring position.On the substrate P that the 2nd carrying device H2 is unloaded, be attached with a little, remove device 100 to liquid by the 2nd carrying device H2 conveyance not by liquid withdrawal system 2 liquid 50 that is over that reclaims.Like this, carry out the exposure-processed of the substrate P that chip bench PST2 kept and the various measurements of the unexposed substrate P that chip bench PST1 is kept side by side, and with liquid remove device 100 carry out on tight front is through with the substrate P of exposure-processed the removing of residual liquid.
In addition, on the substrate P that chip bench PST2 is kept when the fluid Supplying apparatus 1 beginning feed fluid, do not carry out the measurement action of essence at chip bench PST1, but only carry out moving of chip bench PST1, chip bench PST1 is stopped to good.By handling like this, just can prevent that on chip bench PST2 the vibration that produced brings influence to the measurement action of the chip bench PST1 the measuring position when fluid Supplying apparatus 1 beginning liquid is supplied with.In addition, when stopping on chip bench PST2 feed fluid, under the still unclosed situation of measurement action of chip bench PST1 on the measuring position, also can be when stop liquid be supplied with, do not carry out the measurement action of essence at chip bench PST1, but only carry out moving of chip bench PST1, chip bench PST1 is stopped.
Control device CONT is accompanied by the liquid of the 2nd carrying device H2 is removed the approaching with the 1st baffle plate 26A open (with reference to Fig. 5) of device 100.At this moment, the 2nd baffle plate 27A closes.The 2nd carrying device H2 gives the table device 20 that liquid is removed device 100 via the 1st peristome 26 with substrate P.At this moment, cradle portion 21 descends, and substrate P is held in cradle portion 21 and the 2nd cradle portion 24 on the table device 20.
In case substrate P is delivered to table device 20, the 2 carrying device H2 just to be kept out of the way from chamber 25 via the 1st peristome 26.If the 2nd carrying device H2 keeps out of the way then control device CONT closes the 1st baffle plate 26A from chamber 25.Thus, chamber 25 is inner sealed.If chamber 25 is inner sealed, then control device CONT rises cradle portion 21.When cradle portion 21 rose, the substrate P that absorption remains in this cradle portion 21 also rose with respect to table device 20.Then, control device CONT driven in rotation mechanism 22 makes cradle portion 21 be rotated towards θ Z direction with substrate P.Make substrate P rotation by rotating mechanism 22, just disperse from substrate P by means of action of centrifugal force attached to the liquid 50 of the upper and lower surface of substrate P.Thus, just remove attached to the liquid 50 of substrate P from substrate P.Here, because substrate P is configured in chamber 25 inside as lid shell mechanism, so around the liquid 5 that disperses from substrate P can not splash in.
The liquid 50 that disperses from substrate P is reclaimed by the liquid attracting device 29 that is connected to chamber 25.Liquid attracting device 29 is by attracting to reclaim the liquid 50 that disperses from substrate P with chamber 25 gas inside with the liquid 50 that splashes.Here, liquid attracting device 29 is proceeded chamber 25 gas inside and the attraction of the liquid 50 that splashes action.In view of the above, because liquid 50 can not remain in chamber 25 inside such as the inwall of chamber 25 or the end, so that chamber 25 humidity inside can not change is too big.In addition, even when open baffle 26A, 27A, gas moist in the chamber 25 can not flow out to outside the chamber 25 yet.
In case substrate P has rotated the stipulated time (perhaps stipulating rotation number), just the stop the rotation driving of mechanism 22 of control device CONT descends substrate P with cradle portion 21.Then, open the 2nd baffle plate 27A of control device CONT.In case the 2nd baffle plate 27A is by opening, the 3rd carrying device (the 2nd conveyance member) H3 is just via the 2nd peristome 27 visit table devices 20, the substrate P that keeps the liquid 50 on the table device 20 to be removed.Maintenance is removed the 3rd carrying device H3 that device 100 has been removed the substrate P of liquid 50 by liquid, substrate P is taken out of via the 2nd peristome 27 from chamber 25 inside.
As shown in Figure 1, remove the substrate P that device 100 has been removed liquid 50, be transported to applicator developer body C/D via interface portion IF by means of liquid.Applicator developer body C/D (developing apparatus D) implements development treatment to the substrate P that is sent here.Like this, before the exposure device EX-SYS of present embodiment takes out of substrate P applicator developer device CD-SYS via interface portion IF, remove device 100 by means of liquid and remove the liquid 50 that is attached to substrate P.
As described above such, arrive applicator developer device C/D-SYS (developing apparatus D) before owing to will in exposure device body EX, implement the substrate P conveyance of exposure-processed, remove device 100 with liquid and remove the liquid 50 that is attached to substrate P, so can eliminate the influence of liquid 50 for development treatment.In addition, remove the liquid 50 that is attached to substrate P by remove device 100 by liquid, just can prevent that in the conveyance of substrate P liquid falls, causes the 1st chamber device CH1 humidity inside to change (environmental change) from substrate P, perhaps make the generation of the good situation that each device on the conveyance path or parts get rusty etc.
In addition, carry out conveyance with the 2nd carrying device H2, use the 3rd carrying device H3 different to carry out conveyance the substrate P that has removed liquid 50, so the 3rd carrying device H3 can not drenched by liquid 50 with the 2nd carrying device H2 owing to will be attached with the substrate P of liquid 50.Thereby, can attaching liq 50 on the substrate P of the 3rd carrying device H3 institute conveyance, in addition, can prevent the splashing of liquid 50 on the conveyance path of the 3rd carrying device H3 reliably.
In addition,, liquid is arranged in the way in conveyance path of conveyer H, so the liquid that can utilize the exposure-processed of exposure device body EX simultaneously and utilize liquid to remove device 100 is removed processing because being removed device 100.Thereby, can not make productive capacity reduce ground and carry out each processing.And, owing to be to carry out liquid in chamber 25 inside to remove processing, so around can preventing that liquid 50 is splashed to.
In addition, though in the present embodiment, when the applicator developer device C/D-SYS as treating apparatus is arrived in the substrate P conveyance after the exposure-processed, carrying out conveyance via the interface portion IF as connecting portion so is illustrated, but for example in applicator developer device C/D-SYS, possess under the situation of interface portion IF, perhaps be not directly connected under the situation of exposure device EX-SYS via interface portion IF at applicator developer device C/D-SYS, perhaps, treating apparatus be the substrate accommodation device and not via the substrate P conveyance of interface portion IF after with exposure-processed under the situation of substrate accommodation device, the peristome of the 1st chamber device CH1 just becomes the connecting portion of exposure device EX-SYS.
As described above, the liquid in the present embodiment 50 is made of pure water.Pure water can easily obtain in a large number at semiconductor fabrication factory etc., also has not the advantage for the bad influence of photoresist on the substrate P (photoresist) or optical element (lens) etc. simultaneously.In addition, for the bad influence of environment, the amount of impurity is extremely not low simultaneously for pure water, so can also expect the surface of substrate P and be arranged at the effect that the surface of optical element of the front end face of projection optical system PL is cleaned.
And, pure water (water) is that the refractive index n of the exposure light EL of 193nm degree is considered to about 1.44～1.47 with respect to wavelength, penetrate under the situation of light (wavelength 193nm) as the light source of exposure light EL utilizing the ArF exciplex to swash, on substrate P with 1/n, promptly about 131～134nm degree is obtained higher exploring degree by the short wavelengthization.And then, compare in the depth of focus and the air doubly, promptly about 1.44～1.47 times of degree are extended with about n, so under the situation that the situation that can guarantee and use in air gets final product with the depth of focus of degree, the numerical aperture of projection optical system PL is further increased, and the exploring degree also will improve in this.
Though in the present embodiment, at the front end of projection optical system PL lens 60 have been installed, but, can also be used optical sheet in the adjustment of optical characteristics, for example aberration (spherical aberration, coma aberration etc.) at projection optical system PL as the optical element of the front end that is installed on projection optical system PL.It perhaps also can be the planopaallel plate that can see through exposure light EL.By being made as planopaallel plate with the optical element that liquid 50 contacts than lens cheapness, even will make when the carrying of exposure device EX, assembling, adjustment etc. the material that the homogeneity of the illumination of the transmission coefficient of projection optical system PL, the exposure light EL on the substrate P and Illumination Distribution reduces (for example silicon family organism etc.) be attached to this planopaallel plate, only before feed fluid 50, change this planopaallel plate and get final product, have the advantage lower and so on than its replacement cost of situation that will be made as lens with the optical element that liquid 50 contacts.Promptly, the surface of making adhering to of impurity the liquid 50 etc. the optical element that contacts with liquid 50 dirty owing to the particle or result from of splashing that takes place from resist because of the irradiation of exposure light EL, so need change this optical element termly, by this optical element being made as cheap planopaallel plate, compare the cost step-down that just can make the replacing parts with lens, and can make and change the desired time and shorten, can also suppress the low of the rising of maintenance cost (operating cost) or productive capacity.
In addition, under the optical element of the front end of the projection optical system PL produced because of flowing of liquid 50 and the bigger situation of the pressure between the substrate P, can also not replaceable this optical element but firmly fix optical element so that it can be because of this pressure activity.
In addition, though in the present embodiment, be the formation that between projection optical system PL and substrate P surface, is full of, but also can be the constituting of full of liquid 50 under the state that the cover glass be made up of planopaallel plate is installed on the surface of substrate P for example with liquid 50.
In addition, in the respective embodiments described above, the shape of said nozzle does not limit especially, for example can carry out the supply or the recovery of liquid 50 with two pairs of nozzles for the long limit of leading section 60A yet.In addition, since in the case from+directions X or-either direction of directions X all can carry out the supply and the recovery of liquid 50, so also can dispose supply nozzle up and down side by side and reclaim nozzle.
