[0077] Further, the present embodiment Nio, Te is the acceleration meter 90 is provided with a Z acceleration measuring instrument 9 3 a plurality of (three). Specifically, the acceleration meter 90, Z acceleration measuring device is arranged in the X-axis direction on the upper surface of the nozzle member 70 93A, and 93B, a position aligned with respect to the Y-axis direction with respect to the Z acceleration measuring device 93B that it has a Z acceleration measuring device 93C provided.

Alternatively, the X acceleration measuring device 91 1 Tsutoshi, the Y acceleration measuring instrument 92 may be provided two. In short, a plurality of acceleration measuring devices 91 one 93 the acceleration in the direction of six degrees of freedom of the nozzle member 70 may be composed so as to be measured by using.
[0080] Next, Tsu the method of exposing the pattern image of the mask M onto the substrate P by using the exposure apparatus EX having the above configuration, Te be described.
[0081] The controller CONT supplies the parallel line of the liquid LQ with respect to the upper substrate P by the liquid supply mechanism 10, while performing recovery of the liquid LQ on the substrate P by the liquid recovery mechanism 20, for supporting lifting the substrate P while moving the substrate stage PST in the X axis direction (scanning direction), the projection exposure onto the substrate P via the liquid LQ and the projection optical system PL between the pattern image of the mask M and the projection optical system PL and the substrate P to.
[0082] liquid LQ supplied from the liquid supply unit 11 of the liquid supply mechanism 10 in order to form the liquid immersion area AR2 is supply pipes 13A, 13B, and the tube member 16A, after flowing through the 16B, Nozzle member 70 supply passage 14A formed therein, the liquid supply ports 12A through 14B, are supplied to 12B by Ri substrate P. Liquid supply ports 12A, liquid LQ supplied from 12B onto the substrate P is supplied to wets and spreads between the lower end surface and the substrate P at the end portion of the projection optical system PL (optical element 2), the projection area AR1 on a part of the substrate P including, locally form a large liquid immersion area AR2 than and the projection area AR1 smaller than the substrate P. At this time, the control unit CONT, the liquid supply ports 12A disposed in the X axis direction (scanning direction) on both sides of the projection area AR1 of the liquid supply mechanism 10, from each of 12B, both sides or these projection area AR1 in the scanning direction to supply the liquid LQ onto the substrate P simultaneously. Accordingly, the liquid immersion area AR2 is uniform and well formed.
[0083] Further, the liquid LQ on the substrate P via the liquid recovery port 22A of the nozzle member 70, after being recovered from 22B, the recovery flow passage 24A, 24B, tube member 26A, 26B, and the recovery tube 23A, and 23B It is recovered by the liquid recovery section 21 and. At this time, the control unit CONT is capable of controlling the liquid recovery amount per unit time by the liquid recovery unit 21, the liquid LQ of the substrate P is recovered by a predetermined amount per unit time.
The exposure apparatus EX in [0084] this embodiment, the pattern image of the mask M while moving the mask M and the substrate P in the X axis direction (scanning direction) be one which projection exposure onto the substrate P, the scanning exposure times some of the pattern image of the mask M via the liquid LQ and the projection optical system PL of the liquid immersion area AR2 is projected in the projection area AR1, the mask M gar X direction (or + X direction) velocity V synchronously to move, speed beta 'Upsilon beta in the + X direction (or X direction) with respect to the substrate P is the projection area AR1 move the projection magnification). On the substrate Ρ is set a plurality of shot areas, after exposure is completed for one shot area, the next shot area Te cowpea stepping movement of the substrate Ρ is moved to the scanning start position, hereinafter, Step ' the scanning exposure process for each shot area is sequentially performed while moving the substrate Ρ in and 'scan method.
[0085] By performing the supply and recovery of the liquid LQ, Ru if there vibrations on the nozzle member 70 occurs. Further, resulting in board P side by the movement in the Z-axis direction and the tilt direction for moving and focusing 'leveling adjustment to ΧΥ direction of the substrate stage PST for scanning exposure (0 X, 0 Y-direction) in some cases that Tsutawa the nozzle member 70 through the liquid LQ of the vibration component force the liquid immersion area AR2. Also, when scanning the substrate P, it is conceivable to move the nozzle member 70 more viscous resistance of the liquid LQ of the liquid immersion area AR2. In other words, there is a possibility that the liquid LQ of the immersion area AR2 exert a force on the nozzle member 70.
[0086] lower step 7 which supports the nozzle member 70 (main column 1) is also supported projection optical system PL, because the vibration generated by the nozzle member 70 is likely to be transmitted to the projection optical system PL there is. Vibration generated by Bruno nozzle member 70 and is transmitted to the projection optical system PL, Notan image projected onto the substrate P via the projection optical system PL and the liquids LQ deteriorate. Therefore, the controller CON T, using the vibration damping mechanism 60, the vibration of the nozzle member 70 is anti-vibration so as not transmitted to the projection optical system PL.
[0087] When the nozzle member 70 is vibrated, the position of the nozzle member 70 relative to the lower step part 7 of the main column 1 varies, the control unit CONT based on the measurement result of the nozzle position measuring device 80, proof driving the drive device 61- 63 of the oscillating mechanism 60. Position of the nozzle member 70 relative to the lower step part 7 is measured by the nozzle position measuring device 80. The control unit CONT based on the measurement result of the nozzle position measuring device 80 Te, so as to maintain the position of the nozzle member 70 relative to the lower step part 7 in the desired state, i.e., the lower side step part 7 and the nozzle member 70 the positional relationship between so as to keep the a constant to drive the drive device 61- 63 of the anti-vibration mechanism 60.
[0088] At this time, the control unit CONT, X, Y, Zeta position measuring device 81, 82, 83 performs arithmetic processing based on each measurement result, six degrees of freedom of the nozzle member 70 relative to the lower step part 7 the direction of (X-axis, Upsilon axis, Zeta axis, 0 X, θ Υ, and theta Zeta direction) determine the respective position information about. The control unit CONT based on the position information about the direction of the obtained six degrees of freedom, X, Y, by driving the respective Ζ drives 61, 62, 63, the nozzle member 70 relative to the lower step part 7 6 degrees of freedom directions (X axis, Upsilon axis, Zeta axis, 0 Χ, 0 Υ, and 0 Zeta direction) to control the Dear location related.
[0089] Further, the nozzle member 70 because supported by a passive vibration isolation mechanism 72 including an air panel, by the elastic action of the air panel gases and attempts Tsutawaro the lower step 7 from the nozzle member 70 side vibrating it is possible to reduce the high-frequency components. Then, by an active vibration isolation mechanism 65 including a driving device 61- 63, to reduce the relatively low frequency component of the vibration (e.g. 1Hz- 1 OHz), vibration isolation mechanism 60, a vibration damping effect in a wide frequency band it is possible to obtain. Thus, the active vibration isolation using a driving device 61- 63 (active vibration isolation), combining the passive anti-vibration using elastic action of the gas (passive vibration isolation), the Nozzle member 70 that act the vibration is transmitted to the projection optical system PL via the lower step 7 can be effectively suppressed. Also, among the vibration components of the nozzle member 70, a very low frequency components (e.g. 1Hz frequency components lower than), since the influence on the pattern transfer accuracy onto the substrate P is considered to be small, the image stabilization control for the frequency component it is also possible to construct a control system of the vibration isolating mechanism 60 so as not performed. By doing so, prevents non circumstances such as the oscillation of the control system, it is possible to construct a control system with a relatively simple configuration.
[0090] As described above, the vibration isolating mechanism 60, vibration generated by the nozzle member 70, is prevented from being transmitted to the projection optical system PL via the lower step 7 (the main column 1) it can. Therefore, it is possible to prevent deterioration of the pattern image projected onto the substrate P via the projection optical system PL and the liquid LQ.
[0091] Further, vibration isolating mechanism 60 is supported in a state of releasing the nozzle member 70 with respect to the projection optical system PL (optical element 2), Ru. A nozzle member 70 and the projection optical system PL (optical element 2) is supported apart by Rukoto, vibration generated by the nozzle member 70 is not directly transmitted to the projection optical system PL.
[0092] Further, the liquid supply mechanism 10 and liquid recovery mechanism 20, by a predetermined support mechanism is supported in isolation with respect to the barrel constant Release 5. Accordingly, vibration generated in the liquid supply mechanism 10 and liquid recovery mechanism 20, not transmitted to the projection optical system PL via the barrel surface plate 5.
[0093] In the present embodiment, the supply passage 14A of the feed tube 13A, 13B and the nozzle member 70, the 14B, the tube member 16A having a stretchable and flexible, are connected via a 16B . Similarly, the recovery tubes 23A, 23B and the recovery flow passage 24A of the nozzle member, and 24B, the tube member 26A having a flexible stretch available-is connected through a 26B. Therefore, even when driving the nozzle member 70 with a driving dynamic device 61- 63, and summer as unimpeded driving of the nozzle member 70. Accordingly, anti-vibration mechanism 60 can be better vibration-damping support the Roh nozzle member 70 relative to the lower step 7. [0094] Also, although the configuration is mounted reference mirror of the interferometer system for measuring the position information of the substrate stage PST (fixed mirror) to the barrel PK of the projection optical system PL is considered, the projection optical science system PL vibration is a transmitted, by way, also reference mirror of the interferometer system for measuring the position information of the substrate stage PST (fixed mirror) is attached to the barrel PK, the position information of the base plate stage PST measurement, and based on the measurement result! /, were the position control can be accurately performed.
[0095] As described above, the liquid LQ of the liquid immersion area AR2 is also possible to exert a force on the nozzle member 70, the position of the nozzle member 70 is varied by the force, the substrate P and the projection area AR1, Oh Rui is Do disposed at the optimum position is the nozzle member 70 relative to the liquid immersion area AR2, while, also possibility of performing the supply and the recovery of the liquid LQ. In that case, the control unit CONT by using the driving device 61- 63 of the anti-vibration mechanism 60 adjusts the positional relationship between the nozzle member 70 and the lower step 7 (main column 1), the nozzle member 70 it is possible to perform the supply of the liquid LQ for forming the liquid immersion area AR2 in state like disposed in optimum positions and recovery. Therefore, it is possible to accurately immersion exposure liquid immersion area AR2 in good form.
[0096] Further, the control apparatus CONT uses the drive 61- 63, it is possible to adjust the position of the nozzle member 70. Therefore, for example, after liquid immersion exposure completion of the substrate P, in order to recover the liquid LQ on the substrate P (substrate stage PST), the liquid recovery nozzle member 70 by moving the nozzle member 70 in the Z direction (downward) in a state in which close the mouth 22 and the substrate P, and performs the liquid recovery! Chide monkey that was Tsu ヽ.
[0097] Alternatively, in accordance with the liquid immersion exposure condition (the scan speed of the substrate P, the liquid LQ of the physical properties (viscosity), etc.), including the distance between the lower surface 70A of the substrate P surface and the nozzle member 70, the substrate P and the nozzle member the positional relationship between the 70 and adjusted using a drive device 61- 63, it is also possible to immersion exposure. Also, when not using the nozzle member 70, move of Seto nozzle member 70 in the + Z direction (upward direction), Te, and come in contact with the nozzle member 70 and the substrate P or the nozzle member 70 and the substrate stage PST !, so as to prevent.
[0098] Incidentally, you!, Te to the above embodiments, so that the vibration of the nozzle member 70 is not transmitted to the projection optical system PL via the lower step 7, the control unit CONT, the nozzle position measuring device 80 based on the total measurement result of, but driving the driving device 61- 63, based on the measurement result of the acceleration meter 90, the driving device 61- 63 may be driven. At this time, the control unit CONT, X, Y, performs arithmetic processing based on the Zeta acceleration measuring device 91, 92, 93 each measurement result, the direction of six degrees of freedom of the nozzle member 70 (X-axis, Upsilon axis, Zeta axis, 0 Χ, θ Υ, obtain each acceleration information about RX theta Zeta direction).

[0107] FIG. 5 is a view showing another embodiment of the present invention. 5, the exposure apparatus EX, Bei Eteiru the nozzle position measuring device 110 for measuring the positional relation between the base plate stage PST and the nozzle member 70. Nozzle position measuring device 110 includes an X interferometer 111 to measure the positional relationship between the X-axis direction between the substrate stage PST and the nozzle member 70 (111A, 111B), the position in the Y-axis direction between the substrate stage PST and the nozzle member 70 Y interferometer 112 measures the relationship (but not shown in FIG. 5) and, Z interferometer 113 measures the position relationship in the Z axis direction between the substrate stage PST and the nozzle member 70 (113A-113C, However 113C is a V ヽ shown in FIG. 5) and a, Ru.

And each interferometer 111 one 113 and the control equipment CONT is connected, the measurement result of each interferometer 111 one 113 is output to the control device CON T.
[0108] The control unit CONT based on the measurement results of a plurality of interferometers 111 one 103, 6 degrees of freedom directions (X axis, Y axis, Z axis, 0 X, 0 Y, and 0 Z-direction) to a substrate it is possible to obtain the position of the nozzle member 70 against the stage PST.

[0109] As described above, the liquid LQ in the present embodiment is constituted by pure water. Pure water can be obtained in large quantities at a semiconductor manufacturing plant or the like, that it has no adverse effects on the photoresist and the optical element (lens) and the like on the substrate P. Further, pure water has no adverse effects on the environment and contains very few impurities, also acts to clean the surface of the optical element provided surface of the substrate P, and the distal end surface of the projecting projection optical system PL expectations it can. When the purity of pure water supplied factory power is low, the exposure apparatus may be provided with an ultrapure water Manufacturing device.
[0110] Then, the wavelength is the index of refraction n is approximately 1.4 4 purified water (water) with respect to the exposure light EL of about 193 nm, ArF excimer laser light as the light source of the exposure light EL (wavelength 193 nm) If you were use, LZN, i.e. to reduce the wavelength is high resolution of about 134nm obtained on the substrate P. Furthermore, approximately n times the depth of focus than in the air, i.e. about 1.5 because is enlarged to 44 times, when the depth of focus approximately the same as that when used in air may be secured, the projection optical system PL numerical aperture can be made to more increase Caro, and resolution improves on this point.
[0111] In the case of using the liquid immersion method as described above, the numerical aperture NA of the projection optical system is 0.9 one 1.3. Since the when the numerical aperture NA of the projection optical system becomes large, is used as the exposure light conventionally! /, Ru is random polarized light is also evil I spoon is imaging performance by polarization effects, it is therefore preferable to use polarized illumination. In that case, the mask performs a linear polarization illumination to match the longitudinal direction of the line pattern of the line 'and' space pattern (Les chicle), the mask from the pattern of (reticle), S-polarized light component (TE-polarized Mitsunari minute), i.e. it may be as diffracted light of the polarization direction component along the longitudinal direction is Desa morphism many line pattern. If between the resist coated on the projection optical system PL and the substrate P surface is filled with the liquid Ru, between the resist coated on the projection optical system PL and the substrate P surface is filled with air (gas) as compared with a case in which, since the transmittance of the resist surface of the diffracted light that contributes S-polarized light component to improve the contrast (TE-polarized component) becomes high, the numerical aperture NA of 1.0 of the projection optical science system high imaging performance even when the excess can be obtained. Moreover, it is further effective to combine a phase shift mask Ya oblique incidence illumination method, which is adjusted to the longitudinal direction of the Rainpa turn as disclosed in JP-A 6 188 169 discloses (in particular dipole illumination method) or the like as appropriate. For example, forming a transmittance of 6% halftone phase Shifutoma disk (Nono Fupitchi 45nm approximately pattern) is illuminated by a combination of the linear polarized illumination method and the dipole illumination method, the dipole in the pupil plane of the illumination system to dual light 0. 95 illumination sigma defined by the outer contact circle of the bundle, the 0.1 the radius of each light flux at the pupil plane 125 sigma, and the numerical aperture of the projection projection optical system PL and ΝΑ = 1. 2, random Rather than using polarized light, it is possible to focus the depth of the (DOF) is increased by about 150 nm.
[0112] For example, when the ArF excimer laser as the exposure light, with the projection optical system PL having a reduction magnification of about 1Z4, fine line 'and' space pattern (e.g., 25-50 nm about line 'and' space) If the like is exposed on the substrate P, depending on the structure of the mask M (for example, pattern fineness and the thickness of chromium), the mask M acts as a polarizing plate due to the Wave guide effect, P-polarized light component to lower the contrast diffracted light most mask M power of the S-polarized component from the diffracted light (TE-polarized component) of (TM-polarized light component). also to be emitted. In this case, it is desirable to use the linear polarized illumination as described above, even if light irradiation of the mask M with a random-polarized light, if the numerical aperture NA of the projection optical system PL is 0. 9-1. 3 as large But it is possible to obtain high resolution performance.
[0113] Further, when a very fine line 'and' space pattern on the mask M such that the exposure on the substrate P, P-polarized light components by Wire Grid effect (TM-polarized light component). The S-polarized light component (TE-polarized component) there is also likely to be larger than, for example, when the ArF excimer laser as the exposure light, with the projection optical system PL having a reduction magnification of about 1/4, 25 nm greater than the line 'and' scan pace pattern on the substrate P If such is exposed to, because the diffracted light of the S polarization component (TE polarization component) is emitted most mask M power than the diffracted light of the P polarized light component (TM-polarized light component), the opening of the light projecting projection optical system PL the number NA leaves in the Rukoto obtain the high resolution performance even when large as 0. 9-1. 3.
[0114] Further, a mask as disclosed in aligned in the longitudinal direction linearly polarized light illumination (S polarization illumination) only Nag Hei 6-53120 discloses a line pattern (reticle), and centered on the optical axis combination with tangentially of the circle was (peripheral) polarized illumination method that linearly polarizes in a direction oblique incidence illumination method is also effective. In particular, as the pattern of the mask (reticle) is when a line pattern extending in a direction different to Nag only line pattern extending in one predetermined direction are mixed is also disclosed in Japanese Patent Laid-Open No. 6- 53120 to, in the tangential direction of a circle centering on the optical axis by a combination of a polarization illumination method and the zonal illumination method that linearly polarized, it is possible to obtain high imaging performance even when the numerical aperture NA of the projection optical system is large it can. For example, permeability over 6% halftone type phase shift mask (Nono Fupitchi 63nm approximately pattern), polarization illumination method that linearly polarizes light in a direction tangential to a circle centered on the optical axis and the zonal illumination method (zonal when used to illuminate a specific 3Z4) and the illumination sigma 0. 95, and the numerical aperture of the projection optical system PL and Ν a = l. 00, rather than using the random polarized light, depth of focus (DOF) can be increased by about 250 nm, the half-pitch aperture of 55nm about a pattern in the projection optical system NA = l. 2, it is possible to the depth of focus increases approximately LOOnm.
[0115] In this embodiment, the optical element 2 is attached to the tip of the projection optical system PL, and performs the optical characteristics of the projection optical system PL, for example, aberration (spherical aberration, coma aberration, etc.) adjustment of the lens be able to. The optical element to be attached to the tip of the projection optical system PL, and may be an optical plate used to adjust the optical characteristics of the projection optical system PL. Or a exposure light EL plane parallel plate that can transmit a good even ヽ.
[0116] The optical optionally pressure is large, the pressure force than the replaceable its optics Nag between the substrate P and the optical element at the tip of the projection optical system PL caused by the flow of the liquid LQ element Do not move, even when tightly fixed so,.
[0117] Incidentally, in the present embodiment, the space between the projection optical system PL and the substrate P surface that is configured which is filled with the liquid LQ, for example Closing the cover glass becomes a plane-parallel plate force on the surface of the substrate Pヽ it may also be configured to meet the liquid LQ in the state.
[0118] In addition, the liquid LQ of this embodiment may be a liquid other than force water is water, for example, when the light source of exposure light EL is F laser, the F 2 laser beam is not transmitted through water ,
[0119] Furthermore, the substrate P in each of the above embodiments, not only a semiconductor wafer for fabricating semiconductor devices but glass substrates for display devices, the mask used in a ceramic wafer or an exposure apparatus, for a thin film magnetic head or precursor of a reticle (synthetic quartz, silicon Kon'weha) or the like is applied.
[0120] As for the exposure apparatus EX, in the other scanning exposure apparatus by a step-and 'scan type by synchronously moving the mask M and the substrate P to 查露 optical run the pattern of the mask M (scanning scan Tetsu Pas), the mask the pattern of the mask M collectively exposed in a stationary state and a M and the substrate P, in a projection exposure apparatus (Sutetsu Roh step-and-repeat system for moving sequential steps the board P can be applied. Further, the present invention is also applicable to an exposure apparatus of the step 'and' Suteitchi method of partially overlaid and transferred at least two patterns on the substrate P
[0121] In addition, the reduced image of a first pattern in a state wherein the first pattern and the substrate P are substantially stationary with the projection optical science system (e.g. a refractive projection optical system including no catoptric element with 1Z8 reduction magnification) group It can be applied to an exposure apparatus of a type that first pattern and the plate P. In this case, further subsequently, a reduced image of the second pattern in a state where the second pattern and the substrate P are substantially stationary with the projection optical system, the one-shot exposure in the first pattern partially superposes the substrate P It can also be applied to full-field exposure apparatus Sutitsuchi method to.
