Description

Technical Field

[0001] This invention relates to the field of flexible electronics manufacturing technology, specifically to a roll-to-roll mask exposure energy equalization method for flexible reinforcing components. Background Technology

[0002] Roll-to-roll masking refers to a technique in which flexible materials are unwound and transported using automated equipment, and a mask and ultraviolet light source are used to selectively expose the surface coated with photoresist during the movement, thereby defining the desired circuit or pattern. The main application areas of roll-to-roll masking include OLED display manufacturing, flexible circuit boards, and photovoltaic sensors.

[0003] Existing methods for achieving uniform energy distribution in roll-to-roll mask exposure for flexible reinforcements typically involve adding heterogeneous structures and covering the entire surface of the mask during exposure with a photosensitive film. This aims to achieve uniform mask exposure and address the issues of optical path difference and uneven energy distribution caused by height variations during roll-to-roll mask exposure. While this improvement method can achieve more uniform exposure of the surface to be exposed, it fails to analyze the height structure of the surface to be exposed and the time the surface spends in the exposure zone when masking flexible reinforcements. This leads to the inability to determine whether the exposure time of the flexible reinforcement is sufficient based on exposure standards when different structures of flexible reinforcements are in the exposure zone. Consequently, the flexible reinforcement may be overexposed or underexposed, affecting its performance. For example, patent application CN115968099A discloses a gold... The method for manufacturing a reinforcing plate involves providing a metal sheet; creating grooves in the metal sheet to form bosses; and forming a photosensitive film on the surface of the metal sheet with the grooves. This avoids uneven energy distribution caused by height differences. However, other improvements to roll-to-roll mask exposure energy equalization methods for flexible reinforcing parts typically focus on improving energy unevenness at the exposure edges and center. These improvements still fail to address the issue that, during mask exposure of flexible reinforcing parts, the lack of analysis of the height structure of the surface to be exposed and the time the surface spends in the exposure zone makes it impossible to determine whether the exposure time of the flexible reinforcing parts is sufficient based on exposure standards. This results in overexposure or underexposure of the flexible reinforcing parts, thus affecting their performance. Therefore, it is necessary to improve the existing roll-to-roll mask exposure energy equalization methods for flexible reinforcing parts. Summary of the Invention

[0004] This invention aims to at least partially solve one of the technical problems in the prior art by proposing a roll-to-roll mask exposure energy equalization method for flexible reinforcements. This method addresses the issue that existing roll-to-roll mask exposure energy equalization methods, when exposing flexible reinforcements with masks, fail to analyze the height structure of the surface to be exposed and the time the surface spends in the exposure zone. This results in the inability to determine whether the exposure time of the flexible reinforcement is sufficient based on exposure standards when flexible reinforcements with different structures are in the exposure zone, leading to overexposure or underexposure of the flexible reinforcement, thus affecting its performance.

[0005] To achieve the above objectives, this application provides a roll-to-roll mask exposure energy equalization method for flexible reinforcement components, comprising the following steps: Obtain the sample corresponding to the flexible reinforcement to be exposed and record it as the exposure sample; obtain the exposure test based on the process requirements, and obtain the standard exposure parameters corresponding to the exposure sample based on the exposure test results; The exposure area is partitioned and the exposure sub-area is obtained; when the flexible reinforcement is exposed to roll-to-roll mask in the exposure area, the flexible reinforcement entering the exposure area is partitioned and the flexible reinforcement sub-area is obtained based on the partitioning result. The system acquires the exposed parameters of each software sub-region in real time, and controls the light intensity during mask exposure within the exposure area based on the exposed parameters of the software sub-region and the standard exposure parameters.

[0006] Furthermore, the exposure test includes: Based on process requirements, the exposed sample is moved from the conveyor belt to the exposure area, and a camera is placed at the entrance of the exposure area, referred to as the height sensing camera. The height sensing camera is positioned parallel to the upper surface of the conveyor belt, and the orientation of the height sensing camera is perpendicular to the side of the conveyor belt. When the height-sensing camera is turned on, the midpoint of the image recorded by the height-sensing camera is recorded as the sensing midpoint, and the vertical line segment where the sensing midpoint is located in the image recorded by the height-sensing camera is recorded as the sensing centerline.

[0007] Furthermore, the exposure test also includes: When the exposed sample moves from the conveyor belt at the entrance of the exposure area to the exposure area, the height-sensing camera is activated. When any area of ​​the exposed sample coincides with the sensing center line, the height-sensing camera starts recording images. When the height-sensing camera starts recording images, and the sensing center line does not coincide with any area of ​​the exposed sample, the height-sensing camera stops recording images and records the obtained images as height analysis images. All height analysis images are obtained after the exposed sample has completely passed through the conveyor belt at the entrance of the exposure area.

[0008] Furthermore, the exposure test also includes: For any height analysis image: establish a Cartesian coordinate system with the horizontal axis in seconds and the vertical axis in millimeters, denoted as the height analysis coordinate system; denote the duration of the height analysis image as t; for any frame in the height analysis image corresponding to image A, denote the length by which the exposed sample and the sensing centerline in image A coincide as the sample height of image A, denote the time in the height analysis image corresponding to the frame where image A is located as T, and denote the point with coordinates (T, sample height) in the height analysis coordinate system as the height point of image A; Within the height analysis coordinate system, the height points of the images corresponding to all frames within the height analysis image are obtained, and the curve obtained by fitting all height points is recorded as the height feature curve of the height analysis image.

[0009] Furthermore, the exposure test also includes: Based on process requirements, the light intensity of the exposed sample during mask exposure within the exposure area is obtained and recorded as the standard light intensity. The time when the exposed sample begins to be recorded in the height analysis image is recorded as the sample entry time. The time when the foremost tip of the exposed sample in the height analysis image contacts the exit of the exposure area is recorded as the sample exit time. The number of seconds corresponding to the difference between the sample entry time and the sample exit time is recorded as the exposure time corresponding to the height analysis image. The product of the exposure time and the standard light intensity is recorded as the characteristic exposure dose of the height analysis image. Acquire all height analysis images obtained from the exposed sample, and record the height characteristic curves and characteristic exposure doses corresponding to all height analysis images as the standard exposure parameters of the exposed sample.

[0010] Furthermore, the exposure area is partitioned, and exposure sub-regions are obtained. When the flexible reinforcement undergoes roll-to-roll mask exposure in the exposure area, the flexible reinforcement entering the exposure area is partitioned, and the flexible reinforcement sub-regions are obtained based on the partitioning results, including: For the conveyor belt transporting the flexible reinforcement within the exposure area: the area within the conveyor belt exposed by the mask is denoted as the exposeable area; the exposeable area is divided into k equal regions along the moving direction of the conveyor belt, and successively denoted as exposure sub-regions BZ1 to BZ. k And denote the length of the exposed sub-region as L; As the flexible reinforcement moves from the conveyor belt to the exposure area, starting from the very front of the flexible reinforcement, it is divided every L in the opposite direction of the conveyor belt's movement. The resulting multiple regions corresponding to the flexible reinforcement are then sequentially designated as flexible sub-regions RZ1 to RZ. r Where the product of L and r is denoted as E, and E is greater than or equal to the length of the flexible reinforcement in the conveyor belt.

[0011] Furthermore, the exposed parameters of each software sub-region are acquired in real time, and the light intensity during mask exposure within the exposure area is controlled based on the exposed parameters of the software sub-region and the standard exposure parameters, including: For any flexible reinforcement α entering the exposure area for mask exposure: when the flexible reinforcement α moves from the conveyor belt to the exposure area, based on the exposure test, a height-sensing camera is used to acquire all height analysis images corresponding to the flexible reinforcement α, and these are sequentially recorded as real-time analysis images SF1 to SF2. p ; For any real-time analysis image, the height feature curve corresponding to the real-time analysis image is obtained using the height analysis coordinate system based on the exposure test, and recorded as the real-time feature curve; the height analysis image corresponding to the height feature curve with the highest similarity to the real-time feature curve among the standard exposure parameters is recorded as the exposure reference image of the real-time analysis image, and the characteristic exposure dose of the exposure reference image is recorded as the exposure reference value.

[0012] Furthermore, the real-time acquisition of the exposed parameters of each software sub-region, and the control of the light intensity during mask exposure within the exposure area based on the exposed parameters of the software sub-region and the standard exposure parameters, also includes: The area where the flexible reinforcement α is located within the real-time analysis image is denoted as the image reinforcement area, and the flexible sub-region corresponding to the image reinforcement area is denoted as the sub-region to be analyzed. For any sub-region to be analyzed and any sub-region to be exposed: the time from the first overlap of the front end of the sub-region to be analyzed with the sub-region to the time when the sub-region to be analyzed is completely within the sub-region to be exposed is recorded as the sub-region exposure time; the light intensity when the mask is exposed within the sub-region is recorded as the sub-region light intensity; the product of the sub-region exposure time and the sub-region light intensity is recorded as the real-time exposure dose corresponding to the sub-region to be analyzed and the sub-region to be exposed.

[0013] Furthermore, the real-time acquisition of the exposed parameters of each software sub-region, and the control of the light intensity during mask exposure within the exposure area based on the exposed parameters of the software sub-region and the standard exposure parameters, also includes: Sequentially acquire the sub-region to be analyzed and the exposure sub-region BZ1 to the exposure sub-region BZ. k-1 The corresponding real-time exposure dose, and the sub-region to be analyzed and the exposure sub-region BZ1 to the exposure sub-region BZ k-1 The sum of the corresponding real-time exposure doses is recorded as the exposed parameters of the sub-region to be analyzed; When the exposed parameters of the sub-region to be analyzed are obtained, the speed of the conveyor belt transporting the flexible reinforcement α in the exposed area is recorded as V, and the value of L divided by V is recorded as the final area exposure time; the value obtained by subtracting the exposed parameters from the exposure reference value is recorded as the final area exposure meter. When the value of the final area exposure meter divided by the final area exposure time is compared with the value of the exposed sub-region BZ... kWhen the light intensity is equal during mask exposure, the conveyor belt is not controlled; When the value of the final zone exposure meter divided by the final zone exposure time is equal to the exposure sub-zone BZ k When the light intensities are unequal during mask exposure, the exposure metering of the final area divided by the exposure time of the final area is recorded as the exposure enhancement light intensity, and the exposure sub-region BZ is defined as follows. k The light intensity during mask exposure is adjusted to the exposure enhancement light intensity; until the sub-region to be analyzed is completely within the exposure sub-region BZ. k Within the time frame, the BZ sub-area is activated via callback. k The light intensity during mask exposure.

[0014] Furthermore, the real-time acquisition of the exposed parameters of each software sub-region, and the control of the light intensity during mask exposure within the exposure area based on the exposed parameters of the software sub-region and the standard exposure parameters, also includes: Based on the flexible sub-region corresponding to the image enhancement region, in the flexible sub-region RZ1 to the flexible sub-region RZ r The exposed parameters of each sub-region to be analyzed are obtained sequentially from smallest to largest number, and the exposure parameters of the sub-region BZ are then analyzed based on the latest obtained exposed parameters. k The light intensity is adjusted during mask exposure. Sequentially analyze real-time analysis images SF1 to SF2. p The corresponding image enhancement areas are then processed.

[0015] The beneficial effects of this invention are as follows: This application first obtains an exposure sample; then, it performs an exposure test on the exposure sample based on process requirements, and obtains the standard exposure parameters corresponding to the exposure sample based on the results of the exposure test. The advantage of this is that by performing an exposure test on the exposure sample and obtaining the corresponding standard exposure parameters, it is possible to analyze the height structure corresponding to different regions in the flexible reinforcement, thereby obtaining the exposure parameters corresponding to the exposure time required when performing mask exposure on different regions within the flexible reinforcement. This allows for more precise exposure of the flexible reinforcement in subsequent analysis by using the height structure corresponding to the flexible reinforcement entering the exposure area, thus avoiding overexposure or underexposure.

[0016] This application also partitions the exposure area and obtains exposure sub-regions. When the flexible reinforcement is exposed to a roll-to-roll mask in the exposure area, the flexible reinforcement entering the exposure area is partitioned and a flexible sub-region is obtained. Finally, the exposed parameters of each flexible sub-region are obtained in real time, and the light intensity during mask exposure in the exposure area is controlled based on the exposed parameters of the flexible sub-region and the standard exposure parameters. The advantage of this is that by partitioning the exposure area and the flexible reinforcement entering the exposure area separately, more precise exposure control can be achieved for the flexible reinforcement entering the exposure area. This ensures that the exposure intensity is increased or decreased before the flexible reinforcement moves out of the exposure area, based on the exposure progress of the flexible reinforcement, thereby avoiding overexposure or underexposure of the flexible reinforcement, which would affect the performance of the flexible reinforcement.

Detailed Implementation

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Example 1, please refer to Figure 1 As shown, this application provides 1. a roll-to-roll mask exposure energy equalization method for flexible reinforcement components, comprising the following steps: Step S1: Obtain the sample corresponding to the flexible reinforcement to be exposed and record it as the exposure sample; obtain the exposure test based on the process requirements, and obtain the standard exposure parameters corresponding to the exposure sample based on the exposure test results; The exposure test includes: step S101, moving the exposure sample from the conveyor belt to the exposure area based on the process requirements, and placing a camera at the entrance of the exposure area, denoted as the height sensing camera, wherein the position of the height sensing camera is parallel to the upper surface of the conveyor belt, and the orientation of the height sensing camera is perpendicular to the side of the conveyor belt. In the specific implementation process, for example, during a data analysis, the position of the height-sensing camera is obtained as follows: Figure 2As shown in GG, where, Figure 2 In the image, CT represents the conveyor belt that transports the exposed samples within the exposure area; arrow XJ1 indicates the orientation of the height-sensing camera; and arrow XJ2 indicates the direction of movement of the conveyor belt. In step S102, when the height-sensing camera is turned on, the midpoint of the image recorded by the height-sensing camera is recorded as the sensing midpoint, and the vertical line segment where the sensing midpoint is located in the image recorded by the height-sensing camera is recorded as the sensing centerline.

[0020] The exposure test also includes: step S103, when the exposure sample moves from the conveyor belt at the entrance of the exposure area to the exposure area, the height sensing camera is activated; when any area of ​​the exposure sample coincides with the sensing center line, the height sensing camera starts recording images; when the height sensing camera starts recording images, and the sensing center line does not coincide with any area of ​​the exposure sample, the height sensing camera stops recording images and records the obtained images as height analysis images. In the specific implementation process, due to the different sample structures of the flexible reinforcement, multiple independent partitions may appear in the same flexible reinforcement. For example, in the data analysis of this embodiment, the total length of the flexible reinforcement is 160mm, which contains four reinforcement partitions with lengths of 40mm, 40mm, 40mm and 10mm respectively. The length of the partition between the first and second reinforcement partitions is 10mm, the length of the partition between the second and third reinforcement partitions is 10mm, and the length of the partition between the third and fourth reinforcement partitions is 10mm. Therefore, when analyzing the flexible reinforcement in this embodiment, since "when the height sensing camera starts recording images, and the sensing centerline does not coincide with any area of ​​the exposed sample, the height sensing camera stops recording images and records the obtained images as height analysis images," the height analysis images corresponding to the four reinforcement partitions should be obtained separately to conduct a more detailed analysis of the structural height of different areas within the flexible reinforcement. All height analysis images are obtained after the exposed sample has completely passed through the conveyor belt at the entrance of the exposure area.

[0021] The exposure test also includes: step S104, for any height analysis image: establish a plane rectangular coordinate system with the horizontal axis in s and the vertical axis in mm, denoted as the height analysis coordinate system; denot the duration of the height analysis image as t; for any frame in the height analysis image corresponding to image A, denot the length of the exposed sample coinciding with the sensing centerline in image A as the sample height of image A, denot the time in the height analysis image corresponding to the frame where image A is located as T, and denot the point with coordinates (T, sample height) in the height analysis coordinate system as the height point of image A; In the data analysis of this embodiment, for example, when analyzing the second reinforcing partition in the above-mentioned flexible reinforcement, in the image corresponding to a frame with a time of 0.21s in the height analysis image, the length of the exposed sample coinciding with the sensing centerline is 0.2mm. Then, the point (0.21, 0.2) can be recorded as a height point. Step S105: In the height analysis coordinate system, obtain the height points of the images corresponding to all frames in the height analysis image, and record the curve obtained by fitting all height points as the height feature curve of the height analysis image. In the specific implementation process, by placing a height-sensing camera and acquiring height analysis images, the height points corresponding to all frames in the height analysis images are obtained based on the sensing centerline in the images recorded by the height-sensing camera. Then, the height feature curves corresponding to all height points are obtained, which can analyze the height structure of the region within the flexible reinforcement. In subsequent analysis, the regions in the flexible reinforcement are automatically matched through the height feature curves, and based on the subsequently obtained feature exposure measurement, the flexible reinforcement is subjected to more accurate mask exposure.

[0022] The exposure test also includes: step S106, based on process requirements, obtaining the light intensity of the exposed sample when it is exposed to the mask in the exposure area, and recording it as the standard light intensity; recording the time when the exposed sample in the height analysis image begins to be recorded as the sample entry time, recording the time when the foremost tip of the exposed sample in the height analysis image contacts the exit of the exposure area as the sample exit time, recording the number of seconds corresponding to the difference between the sample entry time and the sample exit time as the exposure time corresponding to the height analysis image, and recording the product of the exposure time and the standard light intensity as the characteristic exposure dose of the height analysis image; In a specific implementation process, such as in the data analysis of this embodiment, the light intensity obtained when masking the second reinforcing partition in the above-mentioned flexible reinforcement is 45 mW / cm², and the exposure time is 0.8s. Therefore, it can be calculated that the characteristic exposure metering of the height analysis image corresponding to the second reinforcing partition is 36 mJ / cm². 2 By acquiring feature exposure measurement, in subsequent real-time exposure, when the height feature curve corresponding to the height structure of the flexible reinforcement to be exposed is the same as the height feature curve of the second reinforcement zone as identified by the height sensing camera, the feature exposure measurement of the height analysis image corresponding to the second reinforcement zone can be used to accurately expose the flexible reinforcement to be exposed. Step S107: Obtain all height analysis images obtained from the exposed sample, and record the height characteristic curves and characteristic exposure doses corresponding to all height analysis images as the standard exposure parameters of the exposed sample.

[0023] Step S2: Partition the exposure area and obtain the exposure sub-area; when the flexible reinforcement is exposed to roll-to-roll mask in the exposure area, partition the flexible reinforcement entering the exposure area and obtain the flexible reinforcement sub-area based on the partitioning result. Step S2 includes: Step S201, for the conveyor belt transporting the flexible reinforcement within the exposure area: the area within the conveyor belt exposed by the mask is denoted as the exposeable area; the exposeable area is divided into k regions along the moving direction of the conveyor belt, and sequentially denoted as exposure sub-regions BZ1 to BZ. k And denote the length of the exposed sub-region as L; Step S202: When the flexible reinforcement moves from the conveyor belt to the exposure area, starting from the front end of the flexible reinforcement, the flexible reinforcement is divided every L along the opposite direction of the conveyor belt movement. The multiple regions corresponding to the divided flexible reinforcement are then sequentially denoted as flexible sub-regions RZ1 to RZ. r Where the product of L and r is denoted as E, and E is greater than or equal to the length of the flexible reinforcement in the conveyor belt; In the specific implementation process, the value of k can be specifically set according to the length of the conveyor belt transporting the flexible reinforcement in the exposure area in the analysis. In the analysis of this embodiment, the length of the area exposed by the mask in the conveyor belt in the exposure area is 80mm, so the value of k can be set to 4, thereby obtaining 4 areas with a length of 20mm, and at the same time, the value of L can be obtained as 20mm. If the length of the flexible reinforcement entering the exposure area is 160mm, then starting from the front end of the flexible reinforcement, along the opposite direction of the conveyor belt movement, the flexible reinforcement can be divided every 20mm, thereby obtaining 8 flexible reinforcement sub-regions, that is, the value of r is 8.

[0024] Step S3: Real-time acquisition of the exposed parameters of each software sub-region, and control of the light intensity during mask exposure in the exposure area based on the exposed parameters of the software sub-region and the standard exposure parameters. Step S3 includes: Step S301, for any flexible reinforcement α that enters the exposure area for mask exposure: when the flexible reinforcement α moves from the conveyor belt to the exposure area, based on the exposure test, a height-sensing camera is used to acquire all height analysis images corresponding to the flexible reinforcement α, and these images are sequentially recorded as real-time analysis images SF1 to SF2. p ; Step S302: For any real-time analysis image, obtain the height feature curve corresponding to the real-time analysis image using the height analysis coordinate system based on the exposure test, and record it as the real-time feature curve; record the height analysis image corresponding to the height feature curve with the highest similarity to the real-time feature curve in the standard exposure parameters as the exposure reference image of the real-time analysis image, and record the characteristic exposure dose of the exposure reference image as the exposure reference value. In the specific implementation process, for example, during a data analysis, the real-time feature curve corresponding to the obtained real-time analysis image is as follows: Figure 3 As shown in curve ST1, the height feature curve with the highest similarity to the real-time feature curve obtained through curve comparison is height feature curve ST2 of the height analysis image corresponding to the second reinforcement zone in the above-mentioned flexible reinforcement. Therefore, the height analysis image corresponding to the second reinforcement zone in the above-mentioned flexible reinforcement can be recorded as the exposure reference image, and 36 mJ / cm 2 Recorded as the exposure reference value.

[0025] Step S3 further includes: step S303, where the area of ​​the flexible reinforcement α within the real-time analysis image is recorded as the image reinforcement area, and the flexible sub-region corresponding to the image reinforcement area is recorded as the sub-region to be analyzed; In the specific implementation process, since the height analysis image corresponding to the second reinforcement zone is recorded as the exposure reference image, when performing mask exposure on the sub-area to be analyzed in the flexible reinforcement α, the light intensity during mask exposure should be adjusted to the light intensity during mask exposure on the second reinforcement zone, i.e., 45 mW / cm². Step S304: For any sub-region to be analyzed and any sub-region to be exposed: the time from the first overlap of the front end of the sub-region to be analyzed with the sub-region to the time when the sub-region to be analyzed is completely within the sub-region to be exposed is recorded as the sub-region exposure time; the light intensity when the mask is exposed in the sub-region is recorded as the sub-region light intensity; the product of the sub-region exposure time and the sub-region light intensity is recorded as the real-time exposure dose corresponding to the sub-region to be analyzed and the sub-region to be exposed.

[0026] Step S3 further includes: Step S305, sequentially obtaining the sub-region to be analyzed and the exposure sub-regions BZ1 to BZ. k-1 The corresponding real-time exposure dose, and the sub-region to be analyzed and the exposure sub-region BZ1 to the exposure sub-region BZ k-1 The sum of the corresponding real-time exposure doses is recorded as the exposed parameters of the sub-region to be analyzed; Step S306: When the exposed parameters of the sub-region to be analyzed are obtained, the speed of the conveyor belt transporting the flexible reinforcing member α in the exposure area is recorded as V, and the value of L divided by V is recorded as the final area exposure time; the value obtained by subtracting the exposed parameters from the exposure reference value is recorded as the final area exposure meter. When the value of the final area exposure meter divided by the final area exposure time is compared with the value of the exposed sub-region BZ... k When the light intensity is equal during mask exposure, the conveyor belt is not controlled; In specific implementation, such as in the data analysis of this embodiment, through data acquisition, the sum of real-time exposure doses corresponding to exposure sub-regions BZ1 to BZ3 of the sub-region to be analyzed is obtained as 27 mJ / cm. 2 Therefore, the exposed parameter is 27 mJ / cm. 2The exposure dose in the final region was 36 mJ / cm. 2 Subtract 27mJ / cm 2 That is, 9mJ / cm 2 ; Data acquisition revealed that the speed of the conveyor belt transporting the flexible reinforcing member α within the exposure zone was 100 mm / s. Since L is 20 mm, the final zone exposure time is 0.2 s. Calculation showed that the final zone exposure metering divided by the final zone exposure time yielded a value of 45. The light intensity during mask exposure was 45 mW / cm². This indicates that the sub-region under analysis can be fully exposed within the exposure sub-region BZ4 without overexposure or underexposure. Therefore, no control of the conveyor belt is required. Step S307, when the value of the final area exposure meter divided by the final area exposure time is equal to the exposure sub-region BZ k When the light intensities are unequal during mask exposure, the exposure metering of the final area divided by the exposure time of the final area is recorded as the exposure enhancement light intensity, and the exposure sub-region BZ is defined as follows. k The light intensity during mask exposure is adjusted to the exposure enhancement light intensity; until the sub-region to be analyzed is completely within the exposure sub-region BZ. k Within the time frame, the BZ sub-area is activated via callback. k The light intensity during mask exposure.

[0027] Step S3 further includes: Step S308, based on the flexible sub-region corresponding to the image enhancement region, in the flexible sub-region RZ1 to the flexible sub-region RZ r The exposed parameters of each sub-region to be analyzed are obtained sequentially from smallest to largest number, and the exposure parameters of the sub-region BZ are then analyzed based on the latest obtained exposed parameters. k The light intensity is adjusted during mask exposure. Step S309: Sequentially analyze real-time analysis images SF1 to SF2. p The corresponding image enhancement areas are then processed.
