       BACKGROUND OF THE INVENTION  
       [0005]     1. Technical Field  
         [0006]     The invention relates to a projection objective with a lens arrangement, which can be divided into six lens groups. The first, third, fifth and sixth lens groups have positive power and the second and fourth lens groups respectively have negative power. The division of the lens system into lens groups is described in more detail hereinafter, based on the direction of propagation of the radiation.  
         [0007]     The first lens group is positive and ends with a lens of positive power. A bulge is formed by the first lens group; it is unimportant if negative lenses are also arranged in the bulge.  
         [0008]     The second lens group is of negative total power. This second lens group has as its first lens a lens having a concave lens surface toward the image. This second lens group substantially describes a waist. Here, also it is not of substantial importance if a few positive lenses are included in the second lens group, as long as the waist is maintained.  
         [0009]     The third lens group begins with a lens having positive power and a convex lens surface on the image side, and which can be a meniscus. If a thick meniscus lens is provided as the first lens, the separation of the lens groups can be considered to be within the lens.  
         [0010]     The fourth lens group is of negative power. This fourth lens group begins with a lens of negative power, followed by several lenses having negative power. A waist is formed by this lens group. It is unimportant if lenses having positive power are also contained within this lens group, as long as these influence the course of the beam over only a short distance and thus the waisted shape of the fourth lens group is maintained.  
         [0011]     The fifth lens group has positive power overall. The first lens of this fifth lens group has a convex lens surface on the image side. A bulge is formed by the fifth lens group.  
         [0012]     After the lens of maximum diameter (the bulge), there follow at least an additional two positive lenses in the fifth lens group, further negative lenses also being permitted.  
         [0013]     The sixth lens group is likewise positive in its total power. The first lens of the sixth lens group is negative and has on the image side a concave lens surface. This first lens of the sixth lens group has a considerably smaller diameter in comparison with the maximum diameter of the bulge.  
         [0014]     2. Background Art  
         [0015]     Such projection objectives are in particular used in microlithography. They are known, for example, from the German Applications DE 198 55 108A, DE 198 55 157A, and DE 198 55 158A, in which the Applicant participated, and from the state of the art cited therein. These documents are incorporated herein by reference.  
         [0016]     These projection objectives are usually constructed from purely spherical lenses, since the production and testing technology is advantageous for spheres.  
         [0017]     Projection objectives are known from German Application DE 198 18 444 A1 which have lenses having aspheric surfaces in at least the fourth or fifth lens group. An increase of the numerical aperture and of the image quality can be attained by means of the aspheric surfaces. The projection objectives shown have a length from the mask plane to the image plane of 1,200 mm to 1,500 mm. A considerable use of material is associated with this length. High production costs are entailed by this use of material, since because of the required high image quality only high quality materials can be used. Aspheric lenses up to a diameter of about 300-mm are required, the provision of which is particularly expensive. It is not at all clear in the technical world whether aspheric lenses with such large lens diameters can be provided in the required quality. “Aspheric surfaces” are understood to include all surfaces which are not spherical and which are rotationally symmetrical. Rotationally symmetrical splines can also be considered as aspheric lens surfaces.  
       SUMMARY OF THE INVENTION  
       [0018]     The invention has as its object to provide a projection objective which has as few lenses as possible, with reduced use of material, the aspheric lens surfaces used being as few and as small as possible, with the lowest possible asphericity. A high aperture projection objective of short structure is to be cost-efficiently provided in this way.  
         [0019]     The object of the invention is attained in particular by a projection objective for microlithography having a lens arrangement comprising a first lens group having positive power; a second lens group having negative power; a third lens group having positive power; a fourth lens group having negative power; a fifth lens group having positive power; and a sixth lens group having positive power; wherein a lens at the end of the second lens group, particularly the last lens of the second lens group, or a lens at the beginning of the third lens group, particularly the first lens of the third lens group, has an aspheric surface. In addition, the object of the invention is attained by a projection objective having a lens arrangement having at least a first waist of a pencil of rays, wherein the lens arrangement comprises at least one of the following: a lens having an aspheric surface arranged before the first waist, a lens having an aspheric surface arranged after the first waist, and lenses having aspheric surfaces arranged before and after the first waist.  
         [0020]     In a projection objective with a lens arrangement, by the measure of providing, in the forward half of this lens arrangement, at least one lens provided with an aspheric lens surface, the possibility was realized of furnishing a projection objective of compact construction and having a high image quality.  
         [0021]     In the division of this lens arrangement into six lens groups: a first lens group having a positive power, a second lens group a negative power, a third lens group a positive power, a fourth lens group a negative power, and a fifth and sixth lens group respectively a positive power, a preferred position of the aspheric surface is at the end of the second lens group. It is then arranged, in particular, on the last lens of the second lens group or at the beginning of the third lens group, and indeed preferably on the first lens of the third lens group. A correction of image errors in the region between the image field zone and the image field edge is possible by means of this aspheric lens surface. In particular, the image errors of higher order, which become evident on considering sagittal sections, can be corrected. Since these image errors apparent in sagittal section are particularly difficult to correct, this is a particularly valuable contribution. In an advantageous embodiment, only one lens has an aspheric surface. This has a positive effect on the production costs, since it is the production of highly accurate aspheric surfaces that requires considerable technological effort, which entails increased costs. It was only with the use of exactly one aspheric lens that it was possible to provide a very compact objective, in which case the additional costs for the aspheric lens are not important, since considerable cost savings were connected with the reduction of the required material and of the surfaces to be processed and tested.  
         [0022]     By the measure of providing a lens arrangement that has at least a first waist, an aspheric surface before and an aspheric surface after the waist, a lens arrangement is produced which makes possible a high numerical aperture with high image quality, particularly for the DUV region. In particular, it is possible by the use of these aspheric surfaces to furnish a projection objective of short structure and high image quality. Objectives used in microlithography generally have a high material density over their whole length, so that the reduction of the length is connected with a considerable saving of material. Since only very high-grade materials can be used for projection objectives, particularly for microlithography, the required use of material has a severe effect on the production costs.  
         [0023]     The aspheric surface arranged before the first waist can be arranged at the end of the first lens group or at the beginning of the second lens group. Furthermore, it has been found to be advantageous to arrange an aspheric surface, arranged after the first waist, on the last lens of the second lens group or on the first lens of the third lens group.  
         [0024]     The aspheric surface provided before the first waist in particular makes possible a targeted correction of coma in the region of the image field zone. This aspheric lens surface has only a slight effect on the skew spherical aberration in tangential section and in sagittal section. In contrast to this, the skew sagittal aberration, particularly in the region between the image field zone and image field edge, can be corrected by the aspheric lens surface after the waist.  
         [0025]     The provision of a second aspheric lens surface is thus a worthwhile measure, in order to counter at high numerical aperture a reduction of image quality due to coma.  
         [0026]     In a few cases of application, particularly with very high numerical aperture, it has been found to be favorable to provide a projection objective wherein the third lens group has a lens having an aspheric surface, and, in particular, the last lens of the third lens group has an aspheric surface.  
         [0027]     It has been found to be advantageous to provide a first lens in the sixth lens group with an aspheric surface for a further correction of coma, especially in the region of the image field edge. For this aspheric lens surface, the first lens of the sixth lens group has been found to be a particularly well suited position.  
         [0028]     Furthermore, the numerical aperture can be increased, at constant image quality, by the provision of a further aspheric surface on the last lens of the third lens group.  
         [0029]     It is an advantage of the invention to provide a refractive microlithographic projection objective, wherein all aspheric lens surfaces have a vertex radius (R) of at least 300-mm. Thus the aspheric surfaces are provided on long radii, since the production and testing is easier for lens surfaces with long radii. These surfaces are easily accessible to processing equipment because of their low curvature. In particular, surfaces with long radii are accessible with Cartesian coordinates for tactile measurement processes.  
         [0030]     It has been found to be advantageous to use at least two different materials for achromatization, for projection objectives designed for an illumination wavelength of less than 200 nm, because of the stronger dispersion of the lenses, even with the use of narrowband light sources. In particular, fluorides, especially CaF 2 , are known as suitable materials, besides quartz glass.  
         [0031]     It has been found to be advantageous to provide at least two lenses of CaF 2 , which are arranged before an aperture stop in the fifth lens group, for the correction of color transverse errors.  
         [0032]     It has been found to be advantageous for the further correction of color errors to integrate an achromat after the aperture stop by means of a positive CaF 2  lens and a following negative quartz lens. This arrangement has a favorable effect on the correction of the spherical portions. In particular, longitudinal color errors can be corrected by the lenses after the aperture stop.  
         [0033]     A reduction of the longitudinal error already results in general from the shortening of the length of the projection objective. Thus a good achromatization with a reduced use of CaF 2  lenses can be attained with the objective according to the invention.

     DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS  
       [0045]     The principle of the construction of a projection exposure device is first described with the aid of  FIG. 1 . The projection exposure device  1  has an illuminating device  3  and a projection objective  5 . The projection objective includes a lens arrangement  19  with an aperture stop AP, an optical axis  7  being defined by the lens arrangement  19 . A mask  9  is arranged between the illuminating device  3  and the projection objective  5 , and is supported in the beam path by means of a mask holder  11 . Such masks  9  used in microlithography have a micrometer to nanometer structure, which is reduced by means of the projection objective  5  by a factor of up to 10, particularly a factor of four, and is imaged on an image plane  13 . A substrate positioned by a substrate holder  17  or a wafer  15  is supported in the image plane  13 . The minimum structures which are still resolvable depend on the wavelength λ of the light used for illumination, and also on the numerical aperture of the projection objective  5 , the maximum attainable resolution of the projection exposure device  1  increasing with decreasing wavelength of the illuminating device  3  and with increasing numerical aperture of the projection objective  5 .  
         [0046]     The projection objective  5  contains, according to the invention, at least one aspheric surface to provide a high resolution.  
         [0047]     Various embodiments of lens arrangements  19  are shown in  FIGS. 2-4  and  8 - 10 .  
         [0048]     These projection objectives  5  designed for more stringent requirements for image quality and for resolution, and in particular their lens arrangement  19 , are described in more detail hereinafter. The data of the individual lenses L 101 - 130 , L 201 - 230 , L 301 - 330 , L 401 - 429 , L 501 - 529 , L 601 - 629 , can be found in detail in the associated tables. All the lens arrangements  19  have at least one aspheric lens surface  27 .  
         [0049]     These aspheric surfaces are described by the equation:  
         P   ⁡     (   h   )       =           δ   ·   h   ·   h       1   +       1   -       (     1   -   EX     )     ·   δ   ·   δ   ·   h   ·   h             +       C   1     ⁢     h   4       +   …   +       C   n     ⁢     h       2   ⁢   n     +   2       ⁢           ⁢   δ       =     1   /   R           
 
 in which P is the arrow height as a function of the radius h (height to the optical axis  7 ) with the aspheric constants C 1  through C n  given in the Tables. R is the vertex angle given in the Tables. 
 
         [0051]     The lens arrangement  19  shown in  FIG. 2  has 29 lenses L 101 -L 129  and a plane parallel plate L- 130 . This lens arrangement  19  can be divided into six lens groups, which are denoted by LG 1  for the first lens group through LG 6  for the sixth lens group. The first, fifth and sixth lens groups have positive refractive power, while the second lens group LG 2  and the fourth lens group LG 4 , by which a first waist  23  and a second waist  25  are formed, have negative refractive power. This lens arrangement  19  is designed for the wavelength λ=193.3 nm which is produced by a KrF excimer laser, and has an aspheric lens surface  27 . A structure width of 0.10 μm is resolvable with this lens arrangement  19  at a numerical aperture of 0.75. On the object side, the light transmitted by the lens arrangement propagates in the form of a spherical wavefront. In the objective, the greatest deviation from the ideal wavefront, also denoted by the RMS factor, is 10.4 mλ with respect to the wavelength λ=193.3 nm. The image field diagonal is 28 mm. The constructional length from mask plane to object plane is only 1,000 mm, and the maximum diameter of a lens is 235 mm.  
         [0052]     In this embodiment, this aspheric lens surface  27  is arranged on the side of the lens L 110  remote from the illumination device.  
         [0053]     The projection objective having the previously mentioned good performance data could for the first time be furnished with the use of this aspheric lens surface  27 . This aspheric lens surface  27  serves to correct image errors and also to reduce the required constructional length, with image quality remaining constant. In particular, image errors of higher order in the region between the image zone and image field edge are corrected here by this aspheric surface  27 . This correction brings about, in particular, an increase in the image quality in the sagittal direction.  
         [0054]     The dispersion of the available lens materials increases with shorter wavelengths. Consequently, increased chromatic image errors arise in projection objectives for short wavelengths such as 193 nm or 157 nm. The usual embodiment for 193 nm therefore has quartz glass as the flint and CaF 2  as the crown, as lens materials for achromatization.  
         [0055]     With an overall minimum use of the problematic CaF 2 , care has to be taken in that a CaF 2  lens L 114  in the third lens group LG 3  places an increased requirement on the homogeneity of the material, since it is arranged far from the aperture stop AP. For this purpose, however, it has a moderate diameter, which substantially improves the availability of CaF 2  with an increased requirement.  
         [0056]     For the correction of color transverse error, three CaF 2  lenses L 119 , L 120 , L 121  are arranged in the fifth lens group LG 5 , before the aperture stop AP. An achromat  37 , consisting of a convex CaF 2  lens L 122  and a following meniscus lens L 123  of quartz glass are arranged directly behind the aperture stop AP. These CaF 2  lenses can be of lower quality than the CaF 2  lens L 114 , since quality deviations in the middle region can easily be simultaneously corrected for all image field regions (by lens rotation during adjustment).  
         [0057]     A further CaF 2  lens L 129  is arranged in the sixth lens group. It is possible by means of this lens of CaF 2  to reduce the effects of lens heating and refractive index changes due to irradiation, named compaction.  
         [0058]     The individual data for the lenses L 101 -L 130  can be found in Table 1. The optically utilized diameter of all the CaF 2  lenses is less than 235 mm. Since the availability of CaF 2  is furthermore limited in dependence on the diameter required, the required diameter of the CaF 2  lenses used is of central importance.  
         [0059]     A lens arrangement  19  designed for the wavelength λ=248 nm is shown in section in  FIG. 3 . This lens arrangement  19  has two aspheric lens surfaces  27 ,  29 . The first aspheric lens surface  27  is arranged on the image side on the lens L 210 . It can also be provided to arrange this second aspheric lens surface  27  on the side of the lens L 211  facing toward the illumination device. The two lenses L 210  and L 211  are predetermined for the reception of the aspheric lens surface  27 . Provision can also be made to provide a meniscus lens having an aspheric lens surface instead of the lenses L 210  and L 211 . The second aspheric lens surface  29  is arranged in the end region of the first lens group, on the side of the lens L 205  remote from the illumination device  3 . It can also be provided to arrange this aspheric lens surface  29  on the lens L 206  following thereafter in the beginning of the second lens group.  
         [0060]     A particularly great effect is obtained when the aspherics  27 ,  29  are arranged on lens surfaces at which the incident rays include a large angle with the respective surface normals. In this case the large variation of the angle of incidence is important. In  FIG. 10 , the value of sin i at the aspheric lens surface  31  reaches a value of up to 0.82. Because of this, the two mutually facing lens surfaces of lenses L 210 , L 211  in this embodiment have a greater effect on the course of the rays in comparison with the respective other lens surfaces of the corresponding lenses L 210 , L 211 .  
         [0061]     With a length of 1,000 mm and a maximum lens diameter of 237.3 mm, this lens arrangement has a numerical aperture of 0.75 at a wavelength of 193.3 nm. The image field diagonal is 27.21 mm. A structure width of 0.15 μm is resolvable. The greatest deviation from the ideal wavefront is 13.0 mλ. The exact lens data with which these performance data were attained can be found in Table 2.  
         [0062]     A further embodiment of a lens arrangement  19  for the wavelength 248.38 nm is shown in  FIG. 4 . This lens arrangement  19  has three lenses L 305 , L 310 , L 328  which respectively have an aspheric lens surface  27 ,  29 ,  31 . The aspheric lens surfaces  27 ,  29  have been left at the positions given by  FIG. 3 . The coma of middle order can be adjusted for the image field zone by means of the aspheric lens surface  27 . The repercussions on sections in the tangential direction and in the sagittal direction are then small.  
         [0063]     The additional, third aspheric lens surface  31  is arranged on the mask side on the lens L 328 . The aspheric lens surface  31  supports coma correction toward the image field edge.  
         [0064]     By means of these three aspheric lens surfaces  27 ,  29 ,  31 , there are attained, at a wavelength of 248.38 nm and at a length of only 1,000 mm and a maximum lens diameter of 247.2 mm, the further increased numerical aperture of 0.77 and a structure width of 0.14 μm which can be well resolved in the whole image field. The maximum deviation from the ideal wavefront is 12.0 mλ.  
         [0065]     In order to keep the diameter of the lenses in LG 5  small, and in order for a Petzval sum which, advantageously for the system, should be kept nearly zero, the three lenses L 312 , L 313 , L 314  in the third lens group LG 3  are enlarged. The thicknesses, and thus the diameters, of other lenses, particularly the lenses of the first group LG 1 , have been reduced in order to furnish the required axial constructional space for these three lenses L 312 -L 314 . This is an excellent way to arrange very large image fields and apertures in a restricted constructional space.  
         [0066]     The high image quality which is attained by this lens arrangement can be seen in  FIGS. 5   a - 5   g ,  6   a - 6   g  and  7   a - 7   f.    
         [0067]      FIGS. 5   a - 5   g  give the meridional transverse aberration DYM for the image height Y′ (in mm). All show an outstanding course up to the highest DW′.  
         [0068]      FIGS. 6   a - 6   g  give the sagittal transverse aberrations DZS as a function of the half aperture angle DW′ for the same image heights mm).  
         [0069]      FIGS. 7   a - 7   f  give the groove error DYS, which is nearly zero throughout.  
         [0070]     The exact lens data can be found in Table 3; the aspheric lens surfaces  27 ,  29 ,  31  have a considerable participation in the high image quality which can be ensured.  
         [0071]     A further lens arrangement for the wavelength λ=248.38 nm is shown in  FIG. 8 . With a length of only 1,000 mm, this lens arrangement  19  has, with only three aspheric lens surfaces  27 ,  29 ,  31 , a numerical aperture of 0.8; a structure width of 0.13 μm is well resolvable in the whole image field, whose diagonal is 27.21 mm. The maximum lens diameter is 255 mm and occurs in the region of the fifth lens group LG 5 . The lens diameter is unusually small for the numerical aperture of 0.8 at an image field having a 27.21 mm diagonal. All three aspheric lens surfaces  27 ,  29 ,  31  are in the front lens groups LG 1 -LG 3  of the lens arrangement  19 . The deviation from the ideal wavefront is only 9.2 mλ in this lens arrangement.  
         [0072]     The exact lens data of this lens arrangement can be found in Table 4.  
         [0073]     A further increase of the numerical aperture, from 0.8 to 0.85, could be attained by the provision of a further, fourth aspheric  33  on the side of the lens L 513  remote from the illuminating device. This high numerical aperture, from which there results an acceptance angle of 116.4°, as against an angle of 88.8° with a numerical aperture of 0.70, is unparalleled for the image field with diagonal 27.21 mm. The well resolvable structure width is 0.12 μm, and the maximum deviation from the ideal wavefront is only 7.0 mλ. Such a lens arrangement  19  is shown in  FIG. 9 , and the exact lens data can be found in Table 5.  
         [0074]     In comparison with the preceding embodiments of  FIGS. 1-3  and with the cited DE 198 18 444 A, the last two lenses are united into one lens in this lens arrangement  19 . By this measure, in addition to the savings in lens production, a lens mounting can be saved in the end region, so that constructional space is created for auxiliary devices, especially for a focus sensor.  
         [0075]     A lens arrangement  19  designed for the wavelength λ=157.63 nm is shown in  FIG. 10 . The image field which can be illuminated with this lens arrangement has been reduced to 6×13 mm, with an image field diagonal of 14.3 mm, and is adapted for the stitching process.  
         [0076]     With a length of only 579.5 mm and a maximum diameter of 167 mm, and with four aspheric lens surfaces  27 ,  29 ,  31 ,  33 , a numerical aperture of 0.85 and a well resolvable structure width of 0.07 μm were attained. The deviation from the ideal wavefront is 9.5 mλ at the wavelength λ=157.63 nm.  
         [0077]     The absorption of quartz lenses is quite high because of the short wavelength, so that recourse was increasingly had to CaF 2  as the lens material. Single quartz glass lenses are provided in the region of the waists  23 ,  25 , i.e., in the second and fourth lens groups LG 2  and LG 4 . These quartz glass lenses are to have the highest possible transmission. A further lens of quartz glass, in the form of a meniscus lens L 625 , is provided in the lens group LG 5  to form an achromat. Furthermore in lens group LG 6 , the lens L 628  having an aspheric lens surface is of quartz glass. The aspheric surface  33  is thus constituted of the material which is easier to process.  
         [0078]     The color longitudinal error of this lens arrangement  19  is thus very small, even at this very high numerical aperture.  
         [0079]     The embodiments hereinabove show that good performance data can be attained without aspheric surfaces ( 27 ,  29 ,  31 ,  33 ) having large diameters, especially in the fifth lens group. The small aspheric lens surfaces utilized can easily be made and tested.  
         [0080]     These lens arrangements  19  illustrated in the embodiments show solely the design space set out by the claims. Of course, the features according to the claims and their combinations, put in concrete terms with the aid of the embodiments, can be combined with each other.
