Description of the invention (1) [Technical field to which the invention belongs] The present invention relates to an exposure device for directly exposing a functional pattern on an object to be exposed 'and a method for forming a pattern. In detail, it relates to an exposure device 'based on a reference position set by a photographic mechanism that detects a pre-formed pattern of the object to be exposed as a reference, and uses the reference position as a reference' to control the start of beam irradiation Or stop the irradiation, in order to improve the accuracy of the second function and figure, and reduce the cost of the exposure device. [Previous technology ^ Previously, it was a function-type transfer exposure (Mirror, which is a traditional combination of various layers of liquid crystal display arrays. The photomask is expensive. It is also necessary to transport the laser beam with another photomask at the source of the exposure device.) 'It uses a mask pattern of a phase pattern formed in advance on a glass substrate, and exposes the mask on the object to be exposed, for example, a stepper (S tepper), a symmetrical projection Projection), and a proximity function ( proximity). However, in the exposure device of the multi-layered functional pattern, the accuracy of the functional pattern is overlapped between the fields. Especially for the large photomask used in the formation of large-scale TFTs and color filters, the pattern must require absolute dimensional accuracy, and the price of the photomask must be different. In order to obtain the above-mentioned coincidence accuracy, the function of the bottom layer must be aligned. Patterns are especially difficult to align for large photomasks. In terms of θ, there are also pros and cons of exposures that do not use a mask, but use an electron beam and a laser beam to directly draw a CAD data pattern. Tian Shi Ji Fu. Violation ‘Equipped with laser light source’ for reciprocating scanning of the exposure optical system that emits light and light; and the & light-off mechanism that carries the exposed object controls the & emission status of the laser light source based on CAD data

Explanation of the invention (2) Scan the back and forth while moving the exposed object to the direction perpendicular to the scanning direction of the laser beam, and form a CAD data figure equivalent to the functional figure in a two-dimensional manner (for example, JP 2) 0 (Π-1 4 4 4 1 5 gazette). However, such direct drawing type traditional exposure devices must have a high degree of precision in the arrangement of CAD data patterns. This is the same as the exposure device using a photomask. Functionality is also formed by using a plurality of exposure devices. In the manufacturing process of patterns, if the accuracy between exposure devices is uneven, the accuracy of the coincidence of the functional patterns becomes worse. Therefore, in order to solve such a problem, β In addition, it is necessary to have a high-precision exposure device to increase its cost. Φ In addition, it is necessary to align the underlying functional pattern and CAD data map in advance. This is the same as other exposure devices using photomasks. Therefore, in order to cope with this problem, the present invention aims to provide a pattern accuracy that can improve the coincidence function, and at the same time can reduce the cost of the exposure device. In order to achieve the above object The first invention is an exposure device that uses an exposure optical system to scan a laser beam toward an exposed object, and directly exposes the exposed object to a functional pattern. On the same side of the optical system, and along the conveyance direction of the exposed object, a photographing position is located in front of the laser beam scanning position, to take a photograph of a functional pattern previously formed on the exposure device of the glass substrate as a reference Mechanism; a illuminating device arranged on a functional pattern that uses illumination as a reference in at least one of the up and down directions of the exposed object so that the photographing mechanism can take pictures

Description of the invention (3) structure; and detecting a preset reference position on the pattern taken by the photographing agency and controlling the start or stop of laser beam irradiation based on the reference position Optical system control mechanism. With this configuration, a lighting mechanism provided in at least one of the up-down direction of the exposed object is used to illuminate a functional pattern previously formed on the exposed object as a reference, and the light beam is scanned in the direction of the exposed object conveyance. In front of the position, the camera as the shooting position captures the functional pattern that is used as the reference, and detects the functional pattern that is taken by the optical control mechanism as the reference. The preset reference position is set by the control. With this reference position as a reference, the beam irradiation starts or stops. Therefore, it is possible to perform high-precision exposure of a predetermined functional pattern of the reference position at a predetermined position. When a functional pattern of a plurality of layers is formed, the accuracy of overlapping the functional patterns of the layers can be improved. Therefore, in the case of forming a multi-layered pattern by using a plurality of exposure devices, the problem of lowering the accuracy of functional pattern registration due to the accuracy difference between the exposure devices can be eliminated, and the cost of the exposure device can be suppressed. Also, because the photographic device is arranged on the same side of the exposure optics, the exposure optics and the photography mechanism can be integrally formed to manufacture, which can improve the mechanical stability of this part, reduce the cost, and assemble the device easily. And the lighting mechanism is the same as that of the exposure body arranged in the photographing mechanism. The illumination mechanism is used to illuminate the functional pattern pre-formed on the exposed object from the same side of the photographic mechanism as the reference, and the photographic mechanism is used to acquire the functional pattern as the reference by reflecting illumination. When an opaque film is formed on the reference functional pattern, the reference functional pattern can also be captured. In addition, the exposed system is a transparent substrate, and the lighting mechanism is

Description of the invention (4) The exposed object is arranged in a photo shape in advance, and it is formed in the shape of a dollar, and it is borrowed by the photography agency. As a result, the accuracy of the data obtained by the photographic institution is also improved. Furthermore, the lighting mechanism can use the lighting on both sides of the light body in the up and down direction of the body to perform functional projection lighting as a reference. Either one is taken to make the film on the transparent or opaque pattern of the exposed object transparent or opaque. In addition, according to the invention, the exposed object is exposed to the scanning light. The front is the photographing position, and the direction is at the exposure position of the exposed object in front of the beam scanning, and it is arranged on the functional map lighting mechanism for the exposed object as the reference; and the photographic pattern is detected. A preset reference controls the start or side of the beam irradiation. The high system configuration obtained by the exposure of the exposure is therefore the basis of the structure, and it is based on the 'no matter'-the implementation of the beam 'and it has the exposed photography which is based on the photography as the reference. Stop this to make the accuracy of the image from the subject, the machine that illuminates each other for photography is formed in the same example system, and is directly exposed to the position where the light body is moved to form first. The exposure of the photographed machine with the reference of the optical shadow mechanism as a reference can be exposed, and the exposed body can be replaced with a pre-formed mechanism to borrow the permeability pattern as a reference. For the direction to be transported and on the lesser side exposed to take pre-patterns, the shadow mechanism should be used as the base reference position, and the functional performance of the control unit on the opposite side of the control unit should be optimized to achieve the daylight. The up and down direction is set to be exposed to the exposed lighting or. Cope with functional features that are not. The department's through-the-lens pattern is formed on the exposure body in the beam. The light body is first formed on the camera and used to take pictures.

Description of the invention (5) With the above-mentioned structure, the reference functional figure formed in advance at the exposed position of the exposed object is illuminated by the illumination mechanism provided on at least one side in the up-down direction of the transparent exposed object ' A photographing mechanism with the photographing position in front of the beam scanning position in the conveying direction of the exposed object captures the reference functional pattern through the transparent exposure substrate from below, and detects the image captured by the photographing mechanism through the optical control mechanism. A preset reference position on the reference functional pattern is used to control the start or stop of the irradiation of the light beam that is scanned back and forth based on the reference position. In this way, the accuracy of the functional pattern formed on the object to be exposed / referenced is increased to the accuracy of the predetermined functional pattern. In other words, when a transparent film is formed on the reference functional pattern, the reference functional pattern may be captured to detect the reference position. Therefore, even if the reference functional pattern is covered by an opaque film, the predetermined patterns of the layers can be superposed with high accuracy. In addition, the lighting mechanism is one in which the subject to be exposed is located on the same side of the photographing mechanism. Therefore, the illumination mechanism is used to illuminate the functional pattern pre-formed on the exposed object from the same side of the photographic mechanism, and the reference pattern is captured by the photographic mechanism by reflected illumination. Therefore, when an opaque film is formed on the reference functional pattern, the reference functional pattern can still be captured. In addition, the lighting mechanism is one in which the exposed object is disposed on the side of the photography mechanism. Therefore, the illumination mechanism illuminates the functional pattern previously formed on the transparent exposed body from the reverse side of the photographic mechanism as a reference, and the photographic mechanism obtains the reference functional pattern through the illumination. Therefore, the comparison of the images obtained by the photography agency can be improved, and the accuracy of acquiring the image data can be improved, so that 'high-precision exposure can be achieved.

Description of the invention (6) Furthermore, the lighting mechanism is arranged on both sides of the object to be exposed in the vertical direction and can be used interchangeably. Therefore, the lighting mechanisms provided on the upper and lower sides of the exposed object are used interchangeably, and the functional pattern based on the & Ming pre-formed on the exposed object is used as a reference. A functional pattern based on ingestion. Therefore, regardless of whether the exposed object is transparent or opaque, and regardless of the functional figure formed as a reference, the film on the model is transparent or opaque, and can be handled by the same exposure device.

Description of the invention (8) The direction in which the light beam travels in the setting direction of the polygon mirror 12 described below belongs to a plane mirror. Furthermore, the polygon mirror 12 is used for reciprocating scanning of a laser beam, such as eight mirrors formed on the side of a regular octagonal cylindrical rotating body. At this time, the laser beam reflected by one of the mirrors is scanned in the one-dimensional direction along with the rotation of the polygon mirror 12 in the direction of 〃, and the position where the laser beam is irradiated moves to the next mirror surface to return to the complex direction instantly. Following the rotation of the polygon mirror 12 again, one-dimensional scanning in the 〃 direction is started. The f 0 lens 13 is used to make the scanning speed of the laser beam equal to the speed on the glass substrate ′. The focal position is arranged at a position approximately the same as that of the polygon mirror [2. The second mirror 14 is used to reflect the laser beam passing through the f 0 -lens 13 and make it incident on the surface of the glass substrate 8 slightly perpendicular to the plane mirror. On the surface near the exit side of the lens of ίθ, near the part where the laser beam scanning start side of the complex scan is located, a line sensor 17 is set to be orthogonal to the scanning direction to detect the predetermined scanning position of the laser beam and the actual The scan position is offset, and the laser beam scanning start time is detected at the same time. In addition, this on-line sensor 17 is not only on the f 0 lens 1 3 side, but can be installed anywhere as long as it can detect the laser beam scanning start point. For example, it can also be provided on the glass substrate transporting platform 18 to be described later. . . A transport mechanism 4 is provided below the first mirror 14 '. This transport mechanism 4 is to carry the glass substrate 8 on the platform 18, and to transport it at a predetermined speed in a direction orthogonal to the laser beam scanning direction. It has a mobile platform 18, such as a transport roller 19, such as The conveyance drive unit 20 such as a motor that drives the conveyance rollers 3 in a rotary manner is 20. 7 On the conveyor: the laser beam sweeping in the conveying direction shown by arrow a above the structure 4

Description of the invention (12) Next, the operation of the exposure device 1 configured as described above and the method of forming the pattern will be described. When the power is first applied to the exposure device 1 ', the optical system control mechanism 7 is driven. When the laser light source 2 is activated, a laser beam is emitted. At the same time, the polygon mirror 12 starts to rotate and can scan the laser beam. However, at this time, the optical switch 9 is still in the state of 0 F F, and the laser beam is not irradiated yet. Next, the glass substrate 8 is mounted on the stage 18 of the conveyance mechanism 4. In this "Xibu", since the conveying mechanism 4 conveys the glass substrate 8 at a constant speed, as shown in Fig. 6, the scanning position of the laser beam (arrow B) is inclined relative to the moving direction of the station 18 (arrow A). to. Therefore, if the glass substrate 8 is set parallel to the movement f direction (arrow A), as shown in Figure (a), the exposure position may be in the black matrix 2 1 when scanning starts at day 2 2 a and at the end of scanning 2 2 b is shifted. In this case, as shown in Figure (b), the glass substrate 8 may be tilted to the conveying direction (arrow A direction), so that the arrangement direction of the pixels 22 and the scanning trajectory of the laser beam (arrow B) can be consistent with each other. . However, in fact, since the scanning speed of the laser beam is much faster than the conveying speed of the glass substrate 8, the above-mentioned offset is not too large. Therefore, it is also possible to set the glass substrate 8 parallel to the moving direction and measure the offset by using the data captured by the photographing mechanism 5 and control the light deflection mechanism 10 of the exposure optical system 3 to correct the offset. In addition, in the following description, the offset is considered to be negligible. _ Next, move the drive unit 2 in the direction of arrow A in Figure 1 〇 Mobile station = ^ At this time, the transport controller 2 6 of the optical system control mechanism 7 is used to control the structure.

Description of the invention (13) The daylight image data of matrix 21 detects the exposure start position and the end position of exposure. The method of forming a pattern will be described below with reference to the flowchart shown in FIG. First, in step S1 ', a picture of the pixel 22 of the black matrix 2 丨 is obtained by the photographing mechanism 5. The acquired image data is sent to three ring buffer memories 3 3 a, 3 3 B, and 3 3 c for day image processing not shown in FIG. 4 for processing. Then, the latest • and three data are output from each of the ring buffer memories 3 3 A, 3 3 β, and 3 3 c. At this time, for example, the first two data are output from the ring buffer memory 33A, the previous data is output from the ring buffer memory 3 3B, and the latest data is output from the ring buffer memory 3 3 C. In addition, each of the data is composed of three rows of memory 3 4A, 3 4B, and 3 4C. For example, a 3 × 3 image of a CCD day element is arranged on the same time axis. The result is the portrait shown in Figure 8 (a). If this image is digitized, it corresponds to the value of 3 X 3 shown in the same figure (b). These digitized day images are aligned on the same time axis, and are digitized to compare the circuit 35 with the threshold value. For example, when the threshold value is 4, 5 ", the image in the same figure (a) can be binarized as in the same figure (c). Next, in step S2, the reference positions at which the exposure starts and the end of the exposure can be detected. Specifically, the detection of the reference position is obtained by comparing the above-mentioned binary data with the exposure start position obtained from the memory unit 30 shown in Fig. 1 by using the data of the LUT by using the exposure start position determination circuit 36. 'φ For example, when the first reference position for specifying the exposure start position is set at the upper left corner of the black matrix 2 1 of the black matrix 2 shown in FIG. 9 (a), the exposure start LUT is the same as that shown in (b) At this time, the data of the exposure start LUT is °,, 0 0 0 0 1 1 0 1 1.

When the corner is the first reference position, the row of the camera 5 corresponding to the first reference position [the component address on the cd, for example,, 1 0 0 0 ”,, 4 0 0 0” is the optical switch controller 24 On the other hand, the above-mentioned binary data is compared in the end-of-exposure determination circuit 37 with the exposure-end position obtained by the memory section 30 shown in FIG. 1 using [υτ data, for example, specifying the address of the end-of-exposure address. The second reference position is set to the black moment shown in Figure 1 (a) When the pixel 2 of the array 2 1 is at the upper right corner, the LUT at the end of exposure is the same as shown in Figure (b). At this time, the data of the LUT at the end of exposure is 1, 1 0 1 1 0 0 〇 (T . As a result of the comparison between the above-mentioned binary data and the LUT data for the exposure position, 11 001 1 0 00. When the two data match, the image data obtained by the photographing agency 5 is determined to be the end of the exposure. The reference position, and the end-of-exposure determination result is output by the end-of-exposure position determination circuit 37. In addition, as in the case described above, for example, when there are 6 day elements 2 2 juxtaposed as shown in FIG. 10, the upper right end of each pixel 2 2 The corner is the second datum
第18頁 200537257 五、發明說明(15) 置。 依據上述判定結果,在第5圖所示計數回路3 8 B計算上 述之相符次數。於是其計得數在比較回路3 9 B與第1圖所示 記憶部3 0所得之曝光終了晝素號碼相比較,兩數值一致 時,輸出曝光終了信號於第1圖所示之調變數據製成處理 部3 1。此時如圖所示,例如於雷射光束掃描方向,決定第 .一畫素221及第四畫素224之右上端角落為第二基準位置 時,對應於該第二基準位置的攝影機構5之行CCD上元件地 址,例如、、1 9 0 0,, ,,4 90 0 "即被光開關控制器22所記Page 18 200537257 V. Description of Invention (15). Based on the above determination result, the above-mentioned matching times are calculated in the counting circuit 3 8 B shown in FIG. 5. Therefore, the calculated number is compared in the comparison circuit 3 9 B with the exposure end day number obtained in the memory portion 30 shown in FIG. 1. When the two values are consistent, the exposure end signal is output as the modulation data shown in FIG. 1. Finished processing section 31. At this time, as shown in the figure, for example, when the upper right corner of the first pixel 221 and the fourth pixel 224 is determined as the second reference position in the laser beam scanning direction, the photographing mechanism 5 corresponding to the second reference position The address of the component on the CCD, such as, 1,900, 4,900, " is recorded by the optical switch controller 22.
。於是如上述情形,曝光開始位置及曝光終了位置的基 位置被檢出後,即進入步驟S3。 步驟S3中檢出在玻璃基板8移動方向之曝光位置。於 此如第3圖所示,雷射光束掃描位置F與攝影機構5攝影位 置E間之距離係設定為沿畫素2 2移動方向的排列節距p的整 數倍(η倍),因此計算雷射光束知描週期,即可得知曝光 位置。例如第1 2圖所示,雷射光束掃描位置與攝影機構5 攝影位置間之距離D設定為畫素2 2排列節距ρ之例如3倍 時,在步驟S 2中檢出位於畫素2 2端部之第一及第二基準位 置後(參照同圖(a))’俟玻璃基板8移動而畫素列中心線抵 鬱攝影機構5之攝影位置(參照同圖(b))時,與雷射光束婦 描開始時機一致。於是雷射光束以週期T掃描時,玻璃基1" 板8之搬運速度被控制成與雷射光束之週期τ同步移動書 22的一節距份。由是在下一次之^間,畫素22就^動^同 圖(c)所示位置。再2T後,畫素22移動同(d)所示位置,於. Therefore, as described above, after the base positions of the exposure start position and the exposure end position are detected, the process proceeds to step S3. An exposure position in the moving direction of the glass substrate 8 is detected in step S3. Here, as shown in FIG. 3, the distance between the laser beam scanning position F and the photographing mechanism E's photographing position E is set to an integer multiple (η times) of the arrangement pitch p along the moving direction of the pixel 22, so it is calculated The laser beam knows the scanning period, and the exposure position can be known. For example, as shown in FIG. 12, when the distance D between the scanning position of the laser beam and the shooting position of the photographing mechanism 5 is set to be 3 times the pixel 2 2 arrangement pitch ρ, for example, the pixel 2 is detected in step S 2. After the first and second reference positions of the two end portions (refer to the same figure (a)) 'when the glass substrate 8 moves and the center line of the pixel row abuts the photographing position of the photographing mechanism 5 (refer to the same figure (b)), The timing coincides with the start of laser beam tracing. Thus, when the laser beam is scanned at a period T, the carrying speed of the glass substrate 1 " plate 8 is controlled to move one pitch of Book 22 in synchronization with the period τ of the laser beam. Therefore, in the next time, pixel 22 will move to the same position as shown in Figure (c). After 2T, pixel 22 moves to the position shown in (d).
第19頁 200537257 五、發明說明(16) --- 是3T後,如同圖(e)所示,畫速22的列中心線就抵達於雷 射光束之知描位置。如此就可檢出曝光位置。 其次在步驟S4中,一面以雷射光束掃描,一面調整曝 光位置。具體而言,如第1 3圖所示,曝光位置的調整,係 以一f0透鏡中所設行傳感器17檢出之現在雷射光束掃描位置 (7L件地址)與既定基準元件地址比較而檢出其偏差量,控 制光偏向機構1 0使雷射光束掃描位置與基準元件地址(美 準掃描位置)一致。 其次,於步驟S5中,開始曝光,係藉光開關控制器24 #制光開關9的動作。此時首先使光開關9成〇N的狀鳆而以 -雷射光束掃描,並界行傳感器17檢出雷射光束的掃^開始 .時刻後立即關閉光開關9。此時可從調變數據製成處理° 3 1讀出例如對應於第丨〇圖之曝光開始位置的攝影機構5 元件地址、、1 0 0 0 "而控制部32演算出從雷射光束掃描 時刻至曝光開始位置之時間t丨。此時預先計測從雷射: 的掃描開始時刻至攝影機構5之元件地址、' 丨〃的掃描時門 10 ’並使雷射光束的掃描速度同步於攝影機構5之行Ccj)時 間軸CLK,則由計算至元件地址、、丨〇 〇 〇 〃止之時間軸數,、 可谷易求得掃描開始時刻11 = t 〇 + 1 〇 〇 〇 c L K。由是在雷射 • |束掃描開始時刻至11後,使光開關9 0 N而開始曝光。 其次在步驟S 6中檢出曝光終了位置。與上述情形一 _樣,例如在元件地址、、1 9 〇 〇,,之曝光終了時刻t 2 = 10 + 1 9 0 0CLK求得。由是在雷射光束掃描開始時刻至12後關閉 '光開關9而終止曝光。Page 19 200537257 V. Description of the invention (16) --- After 3T, as shown in Figure (e), the center line of the column at the drawing speed 22 reaches the position of the laser beam. This will detect the exposure position. Next, in step S4, the exposure position is adjusted while scanning with a laser beam. Specifically, as shown in FIG. 13, the adjustment of the exposure position is performed by comparing the current laser beam scanning position (7L address) detected by the line sensor 17 set in an f0 lens with the predetermined reference element address. The deviation amount is controlled, and the light deflection mechanism 10 is controlled so that the laser beam scanning position is consistent with the reference element address (US standard scanning position). Next, in step S5, the exposure is started, which is based on the operation of the light switch controller 24 #light control switch 9. At this time, the optical switch 9 is first scanned with a laser beam, and the scanning of the laser beam is detected by the boundary line sensor 17. The optical switch 9 is closed immediately after the time. At this time, the modulation data can be created and processed. 3 1 reads, for example, the camera address 5 corresponding to the exposure start position of the image in FIG. 1 and the control unit 32 calculates the laser beam from the laser beam. The time t 丨 from the scanning time to the exposure start position. At this time, the scanning time from the laser: to the component address of the camera 5 and the scan time gate 10 'of the camera 5 are measured in advance, and the scanning speed of the laser beam is synchronized with the time of the camera 5 (Ccj) time axis CLK, From the calculation to the component address, the number of time axes until 丨 〇〇〇〃, can be easily obtained from the scan start time 11 = t 〇 + 1 〇〇〇c LK. The exposure is started by turning the optical switch 90 N after the laser scanning start time until 11 o'clock. Next, the end-of-exposure position is detected in step S6. As in the above case, for example, it can be obtained at the end of the exposure of the device address, 1 900, t 2 = 10 + 19 0 0CLK. The exposure is terminated by turning off the 'light switch 9' after the start time of the laser beam scan to 12 o'clock.
200537257 五、發明說明(17) 其次在步驟S 7中,判斷雷射光束之一巡掃描是否終 了 。如果判斷為N 0 〃 ,則回歸S 2而重複上述動作。於是 在S 2中,如第1 0圖所示,例如檢出第二曝光開始位置 "4 0 0 0 及第二曝光終了位置、' 4 9 0 0 ",則京S 4而進入 S 5,與上述情形一樣,從元件地址a 4 0 0 0 β開始曝光,而 曝光終了於元件地址Μ 9 0 0 〃 。 . 又在步驟S7中,如果判斷為^ YES β ,即回歸S 1,移 行於新的曝光位置檢出動作。於是上述動作反覆進行結 /果,在所希望之領域形成曝光圖形。 φ 如此,依照本發明之曝光裝置及圖形之形成方法,係 -1攝影機構5取得之玻璃基板8上預先形成的黑色矩陣2 1之 晝素2 2畫像,檢出在其上預先設定之基準位置,並以此為 ’基準進行雷射光束之照射開始與照射停止之控制,由是形 成曝光圖形,這樣一來,可提高畫素22的曝光精度。 又因依據畫素2 2上預先設定之基準位置形成曝光圖 形,可排除起因於曝光裝置間精度差之機能性圖型重合經 度劣化的問題,因此應用於使用複數之曝光裝置1形成積 層圖形之製程仍可確保很高的重合經度。藉此可抑制曝光 裝置1之成本。 • _ 再者,藉配置照明機構5於曝光光學系3之同側,可將 兩者一體成形,故可提高此部分的機械安定性,減低成 本,組裝裝置也容易。 於此,藉配置照明機構6於以透明玻璃基板8為界攝影 〜機構5之相反側,可提高攝影機構5所取得畫像的對照及畫200537257 V. Description of the invention (17) Next, in step S7, it is judged whether one of the laser beam scanning scans has ended. If it is determined that N 0 〃, the process returns to S 2 and the above operation is repeated. Therefore, in S 2, as shown in FIG. 10, for example, if the second exposure start position " 4 0 0 0 and the second exposure end position " 4 9 0 0 " are detected, then S 4 enters S 5. As in the above case, the exposure starts from the element address a 4 0 0 0 β, and the exposure ends at the element address M 9 0 0 〃. In step S7, if it is determined that ^ YES β, it returns to S 1 and moves to the new exposure position to detect the action. Then, the above-mentioned actions are performed repeatedly, and an exposure pattern is formed in a desired area. φ In this way, according to the exposure device and pattern forming method of the present invention, it is a black matrix 2 1 daytime element 2 2 image formed in advance on the glass substrate 8 obtained by the -1 photographing mechanism 5, and a pre-set reference is detected thereon. Position, and using this as a reference to control the start and stop of the laser beam irradiation, so as to form an exposure pattern, the exposure accuracy of the pixel 22 can be improved. Because the exposure pattern is formed according to a preset reference position on the pixel 22, the problem of functional pattern overlap and longitude deterioration caused by poor accuracy between exposure devices can be ruled out. Therefore, it is applied to the use of multiple exposure devices 1 to form laminated patterns. The process still ensures a high coincidence longitude. Thereby, the cost of the exposure apparatus 1 can be suppressed. • _ Furthermore, by arranging the lighting mechanism 5 on the same side of the exposure optical system 3, the two can be formed integrally, so the mechanical stability of this part can be improved, the cost can be reduced, and the device can be easily assembled. Here, by arranging the lighting mechanism 6 on the transparent glass substrate 8 as the boundary to the side opposite to the mechanism 5, the contrast and drawing of the image obtained by the photography mechanism 5 can be improved.
