Description of the Invention: [Technical Field] The present invention relates to an exposure apparatus for exposing exposure light to an exposed body supported on a platform via a photomask to form a predetermined pattern, in detail, With respect to an exposure apparatus, a non-periodic pattern exposure of a large-area exposed body can be performed with high resolution. [Prior Art] The conventional exposure apparatus is configured to intermittently illuminate an exposure light that is conveyed at a constant speed through a mask to expose a mask pattern of the mask to a specific position, and is provided with: The image pickup mechanism is disposed such that it can be photographed at an exposure position of the photomask or closer to the conveyance direction of the object to be exposed than the exposure position, and has a direction substantially orthogonal to the conveyance direction. a plurality of X-ray elements; the second imaging means is arranged to be capable of imaging the exposure position of the mask or the proximity of the exposure direction of the object to be exposed; a plurality of light receiving elements arranged in a substantially parallel manner; the alignment mechanism is configured to relatively move the exposed object and the mask in a direction substantially orthogonal to the transport direction to correct an exposure position of the mask; and a control mechanism And detecting, by the ith imaging unit, the exposure position correction for the preset on the exposed objecta reference position, wherein the driving of the alignment mechanism is controlled according to the above, and when the exposure of the exposure light preset on the exposed object is detected by the first imaging mechanism, the remaining position is "2", (4) the exposure light In the case of the conventional exposure apparatus, when the exposure apparatus (substrate) is subjected to exposure with a periodic pattern, It is easy to control the irradiation timing of the exposure light at a specific cycle while transporting the substrate at a certain speed in a specific direction, but the exposure of the non-periodic pattern is difficult. Further, the exposure is relatively close to the opposite direction of the wire. Therefore, due to the presence of the viewing angle (collimation half-angle) in the light source of the illuminating light, there is a problem that the pattern image on the substrate is reduced, and the fine pattern cannot be exposed to form a fine pattern. Although it is possible to use a stepper exposure device (exposing the image of the reticle to the substrate by reducing the projection by the imaging lens), In the case of exposing a large-area substrate having a size of, for example, 1 m £ or more, there is a problem that the lens aperture to be used becomes larger in accordance with the size of the substrate, which becomes an expensive object. [Invention] A problem is to provide an exposure apparatus capable of performing exposure of a non-periodic pattern of a large-area exposed object with a resolution. To achieve the above object, the exposure apparatus of the present invention includes a lens member. The lens member is formed between the stage on which the object to be exposed is placed and the mask on which the cover pattern is formed so as to be movable in a plane parallel to the surface of the object to be exposed and the surface of the mask, and In 8 201219988 two-way! Submitting a mask pattern having a plurality of sheets arranged in a row in a direction, the vertical lens member is such that the plurality of lens groups in which the mask is formed are in a direction intersecting the moving direction: a plurality of lens rows are formed through the through-column; each of the single-dense media/ft, each lens group of each lens row and an axis that obliquely intersects the three-direction direction with respect to the two-type The lines are arranged in parallel with each other. One: the mirror array is formed in a phase intersecting the moving direction, and the adjacent ends are cut into parallel=axis. The lens group of each lens column is spread over the lens. The components are arranged in a certain arrangement pitch. Thus, the lens member formed on the exposed H surface can be formed by the lens member formed on the mask surface of the mask can be moved in parallel to the mask. Exposure to the face-side, even if the cover pattern is a non-periodic pattern, can be exposed with a degree of continuation. In this case, the size of the lens member can be smaller than the size of the mask. From *, even the mask The size is increased corresponding to a large area of the exposed object, and the lens member used can be reduced, and the cost of the part can be reduced. Thereby, the manufacturing cost of the device can be reduced. Further, since the lens member is a plurality of unit lens members The arrangement of the H phase is such that the plurality of unit lens members are arranged differently, so that the Wei-shaped movement can be shortened, and the production time of the exposure process can be shortened. Further, each of the unit lens members is such that each of the lens groups overlaps in a direction in which the lens member is moved in the direction of movement of the lens member. This even if the cover pattern is larger than the lens size, it will be cut off in the middle, and can be continuously connected for exposure. Further, each unit lens member is aligned and overlapped by corresponding convex lens pairs of the first, second, third, and fourth lens arrays in which the plurality of convex lenses are formed corresponding to each other in the front surface of the transparent substrate, and The intermediate inverted image of the mask pattern of the reticle is imaged on the $2 lens array. Between the column and the third lens array. Thereby, it is possible to easily form a lens member in which a plurality of unit lenses are arranged in a plurality of planes. Thereby, the manufacturing cost of the lens member can be lowered. Further, each unit lens member is provided adjacent to the surface of the convex lens located on the upstream side in the light traveling direction of the third lens array, and a first aperture having a characteristic opening is provided, and the exposure region formed by the lens group is limited to the lens. Central Department. Thereby, the equal-fold erect image of the mask pattern of the reticle can be accurately imaged on the surface of the object to be exposed, excluding the influence of the aberration of the lens. Thereby, the formation precision of the exposure pattern can be improved. Further, the first aperture opening is an opening having a rectangular shape in plan view, and an area overlapping a portion of the adjacent i-th aperture opening when viewed from a moving direction of the lens member is an entire area of the overlapping portion. Half of it is partially obscured. Thereby, since the exposure patterns are connected, overexposure can be prevented even in the case of performing superimposed exposure. Thereby, the formation accuracy of the exposure pattern can be further improved. Further, each unit lens member is provided adjacent to the surface of the lens on the upstream side in the light traveling direction of the fourth lens array, and is provided with a second aperture which restricts the light beam 8 201219988. Therefore, the first beam diameter can be limited, and the resolution achieved by the lens group of the lens member can be further improved. Further, the platform can transport the object to be exposed in a specific direction, and the lens member moves in a state where the movement of the stage is temporarily stopped. It can be exposed to the exposed body continuously, which improves the efficiency of the exposure process. [Embodiment] Hereinafter, the embodiment of the present invention will be described in detail based on the closed type. Fig. 2 is a front view showing an embodiment of the exposure apparatus of the present invention, and Fig. 2 is a plan view of Fig. 1. This exposure apparatus exposes a non-periodic pattern of a large-area exposure object with high resolution, and includes a transport mechanism 1, a first exposure optical unit 2, and a second exposure optical unit 3. In the following description, the case of the substrate for a thin film transistor (hereinafter referred to as "TFT") in which the object to be exposed is a display device will be described. Fig. 3 is a plan view of the TFT substrate 4 of the present day (fourth), and the exposure patterns of the plurality of signal lines and the scanning lines are formed in the display frame 5 in a predetermined cycle by the other exposure means. In addition, the area 6 which is displayed on the outside of the display area 5 in the same figure by a broken line is formed to form a region 'region 7 for connecting the plurality of signal lines to the signal side material provided on the external signal side driving circuit.

In the same manner as the lens terminal 11 for the signal terminal shown in FIG. 5, each of the unit terminals 25A to 25C for scanning terminals, and the lens group 29 of each lens array 30 are moved relative to the lens member 25 for scanning terminals. The direction (the direction of the arrow C) is obliquely aligned and the axes are arranged in parallel so that the lens rows 30 are displaced by a certain amount in the direction intersecting with the arrow C, and the adjacent end portions 25Aa, 25Ba and 25Bb, 25Ca (see 2) The lens group 29 of each lens array 30 is arranged to be parallel to the above-mentioned axis, and the lens group 29 of each of the scanning terminal lens members 25 is arranged at a constant arrangement pitch. More specifically, the above-mentioned respective scanning terminal lens members are arranged. As shown in Fig. 11 (a), 25A to 25C are arranged at a pitch 匕 (for example, a pitch of 150 μπι) in a direction intersecting with respect to a moving direction of the scanning terminal lens member 25 (in the direction of an arrow c shown in the drawing). The lens array 30 of the lens group 29 is set at a pitch ρ 201219988 (for example, 150 Å pitch) in the moving direction indicated by an arrow C, and each lens group of each lens row 3 观看 is viewed from the above-described shift (arrow C direction). One of the lens arrays 30 adjacent to each other in the overlapping manner is a part of the lens group 30, and is arranged in the direction in which the lens group 29 is arranged. The row pitch P3 of the complex lens group 29 is l/m (m is 2 or more) In addition, each of the scanning terminal lens members 25A to 25C is configured to correspond to each other in the front and back of the transparent substrate as shown in Fig. 1(b).

The image is formed between the second lens array 31b and the third lens array 31c. In this case, the lens group 29 is constituted by eight convex lenses 28a to 28h which are arranged in line with each other in the optical axis. Further, the lens member for the scanning terminal is used. Since the configuration of 25 is the same as that of the unit terminal members η' to 11C for the signal terminals of the first exposure optical unit 2, the specific configuration of the lens group 29 and the function of each of the convex lenses 28 will be omitted.

The width W2 (referenced in Fig. 10) is the same. Thereby, the light passing through the scanning terminal mask 24 can be completely shielded before the movement of the scanning terminal lens member 25 is started and after the movement is completed. Further, a moving mechanism 26 for moving the above-described scanning terminal lens member 25 is provided. The moving mechanism 26 is configured to move the scanning terminal lens member 25 in the direction of the arrow c in FIG. 2 in a plane parallel to the scanning terminal mask 24 and the stage 8, for example, an electromagnetic actuator, an electric platform, or the like. . The person-to-person describes the operation of the exposure apparatus thus constructed. Firstly, by means of the assembly adjustment device of the lens member provided separately, = the surface of each unit of the Wei component (4) is assembled and adjusted in the manner of "in the material value: in the manner of hitting. Specifically, the adjustment is as shown in Fig. 12 = Ming. In the description of the assembly adjustment of the signal terminal _ mirror member u, the assembly adjustment of the scanning terminal mirror member 25 is performed in the same manner, and the description thereof will be omitted. First, in the plural reference mark, 3513 is arranged in a certain order. , p (integer multiple of P!) - straight __ formed on the reference substrate 36 on the opposite side of the configuration signal terminal mirror member ^ second terminal unit lens member 11A - through the shovel ς ί ί ί ί ί ί ί ί ί ί The reference mark 35a performs imaging 22=: The lens member 11 moves in the horizontal plane and is positioned in the micromirror 3; = : 201219988 The reference mark 35a is positioned. Then, the above-mentioned furnace enters the furnace <<> ci The microscope 37 moves horizontally with the arrangement direction of the reference marks 35a and 35b of the above-mentioned bases "5 hex 35a, 35b", and ^ 7 m « .. ^ 乍 horizontally, via the signal U.S. H 35b H UB Lens group 15 to observe the second The number of the == terminal is united by the unit lens member, the head D ^ is moved as shown in the field of view of the microscope 37, and the reference mark 35b of the No. 4 2 is positioned, and then the unit lens member for the signal terminal is also subjected to the same 5 ^^In this case, the lens groups of the reduced-order Wei component U are aligned with the moving direction indicated by the reading head b in FIG. 5 in the intersecting direction arrangement pitch ρι. The signal terminal lens member π and the scanning terminal lens member 25 which have been assembled and adjusted in the above manner are set in the first exposure optical unit 2 and the second exposure optical unit 3, respectively. In this way, the preparation for exposure is prepared. Next, 'the TFT substrate 4 having the signal line and the exposure pattern of the scanning line formed in advance in the display region 5 by another exposure device is positioned, and after being placed at a specific position on the flat σ 8 , the transport mechanism 1 is driven to make the flat opening 8 Moving in the direction of the arrow 图 of Fig. 1 at a constant speed, the substrate 4 is transported in the same direction. At this time, the light sources of the first and second exposure optical units 2, 3 are turned on. Then, the imaging unit θ which is omitted from the opposite side of the first optical unit 2 in the direction in which the substrate is conveyed by a predetermined distance is used to detect the base of the TFT substrate 4, which is omitted in advance. The mark is used to measure the distance of the platform 4 by the position sensing based on the position of the platform 8 at the detection time of the reference mark. Then, the signal side of the substrate for the TFT is once the platform 8 is moved by a predetermined distance. In the terminal forming region 6 of the exposure optical unit 2, the movement of the stage 8 is stopped immediately below the photomask 10. Further, the moving mechanism 12 of the first exposure optical unit 2 is driven to start the lens member for the nickname terminal. 11 is moved in the direction of the arrow B in FIG. 1, and the plurality of lens groups 15 (see FIG. 5) continuously moving in the same direction are used to make the signal terminal cover pattern 13 of the signal terminal mask 1 shown in FIG. The equal-fold erect image is projected on the surface of the TFT substrate 4, and the exposure pattern of the signal-side terminal is formed on the signal-side terminal forming region 6 of the TFT substrate 4. At this time, as shown in FIG. 7, it is limited to the lens group 15. The exposed area of the opening 20 of the first aperture 19, the area corresponding to the overlapping portion 22 is received by the two lens groups 15 which are successively present in the moving direction of the signal terminal lens member u shown by the arrow B in the same figure. The exposure is superimposed, whereby the exposure pattern of the signal side terminal is continuously connected without interruption in the middle. In this case, since the opening 20' of the first aperture 19 corresponds to the portion of the overlapping portion 22 Since the area is formed as one half of the entire area of the overlapping portion 22, the exposure of the two lens groups 15 is performed at a certain depth, and there is no overexposure. The lens member 11 is moved by a specific distance to form a signal terminal for the signal terminal 8 in the signal side terminal forming region 6 of the TFT substrate 4. The full exposure pattern of the cover pattern 13 stops the moving mechanism 12 and starts moving the platform 8 to restart the TFT. The substrate 4 is transported. The sweat σ is moved so that the TFT substrate 4 is moved by a predetermined distance so that the scanning side terminal forming region 7 of the TFT substrate 4 reaches the second exposure light and the scanning terminal mask 24 of the unit 3. Immediately below, the stage 8 is stopped: movement 0. Next, the moving mechanism 26 of the second exposure optical unit w is driven to cause the scanning terminal lens member 25 to start moving in the direction of the arrow c in FIG. 2, and continuously move in the same direction. The multi-lens group 史 (history picture 11) projects the equal-right image of the scanning terminal cover 27 of the scanning terminal for the scanning terminal shown in Fig. 2 on the surface of the gripping substrate 4 to make the scanning side The exposure pattern of the terminal is formed on the scanning side terminal forming region 7 of the TFT panel 4. The exposure region of the opening 33 of the first aperture 32 of the 蚬砰29 corresponds to the region of the overlapping portion. And the case of the signal terminal mirror member u of the exposure optical unit 2 is the same as the two lens groups in which the moving direction of the mirror member is successively 2 =:, the exposure pattern of the scanning side terminal is not interrupted in the middle. , the first / light division and the first exposure unit 2 22 / Τ, with its area becoming the full area of the overlap, so by the stack of the above two lens groups 29 Deep exposure, there will be no overexposure. 201219988 Then, when the scanning terminal lens member 25 is moved by a certain distance and the scanning-side terminal forming region 7 of the TFT substrate 4 is formed with the full-exposure pattern of the scanning-terminal body pattern 27, the moving mechanism 26 is stopped so that the substrate 4 for the TFT is used. The exposure is all over. Thereafter, the movement of the stage 8 is started again so that the TFT substrate 4 is discharged to the outside. In the present invention, the signal terminal lens member u and the scanning terminal lens member 25 each have a plurality of signal terminal sheets.
