As shown in fig. 2, an exposure method of the exposure apparatus 1 according to an embodiment of the present utility model includes:

s1, the upper table 11 and/or the lower table 21 are moved in a direction away from each other, and the substrate is placed on the upper table 11 and/or the lower table 21.

Specifically: in the case where the substrate is one, for example: the upper table 11 may be moved out leftward by the first driving member to transfer the substrate to the upper table 11, and of course, the lower table 21 may be moved out rightward by the second driving member to transfer the substrate to the lower table 21; under the working condition that the number of the substrates is two, the first driving piece can be utilized to move the upper workbench 11 leftwards, the second driving piece can be utilized to move the lower workbench 21 rightwards, and the corresponding substrates are respectively conveyed to the upper workbench 11 and the lower workbench 21. In this way, it is convenient to dispose the substrate on the upper table 11 and/or the lower table 21.

S2, the upper stage 11 and/or the lower stage 21 are moved in a direction toward each other, and one of the upper exposure tool 13 and the lower exposure tool 23 exposes one surface of the substrate.

That is to say: in the case where the substrate is one, for example: after the substrate is carried onto the upper table 11, the first driving member may drive the upper table 11 to move rightward, and in the process of moving rightward, the substrate is subjected to pattern exposure by the lower exposure member 23, and after the exposure is completed, the position of the upper table 11 is located right above the lower table 21. Of course, after the substrate is transferred onto the lower table 21, the second driving member may drive the lower table 21 to move leftwards, and in the process of moving leftwards, the upper exposure member 13 is used to perform pattern exposure on the substrate, and after the exposure is completed, the position of the lower table 21 is located right below the upper table 11.

In the working condition that the number of substrates is two, after the corresponding substrates are respectively conveyed to the upper workbench 11 and the lower workbench 21, the first driving member can drive the upper workbench 11 to move rightwards, and in the moving process, the upper exposure member 13 can perform pattern exposure on one surface of the substrate positioned below, and meanwhile, the lower exposure member 23 can perform pattern exposure on one surface of the substrate positioned above. Alternatively, the second driving member drives the lower stage 21 to move leftward, and during the movement, the upper exposure member 13 may perform pattern exposure on one side of the substrate positioned below, while the lower exposure member 23 may perform pattern exposure on one side of the substrate positioned above. Of course, the first driving member may drive the upper table 11 to move rightward while the second driving member drives the lower table 21 to move leftward, and the upper exposure member 13 may perform pattern exposure on one side of the substrate positioned below while the lower exposure member 23 may perform pattern exposure on one side of the substrate positioned above during the movement of the upper table 11 and the lower table 21 toward each other.

S3, the substrate on the upper table 11 is exchanged onto the lower table 21, and/or the substrate on the lower table 21 is exchanged onto the upper table 11.

In the case where the substrate is one, for example: after one surface of the substrate on the upper stage 11 is exposed by the lower exposure member 23, the substrate on the upper stage 11 may be exchanged onto the lower stage 21, facilitating subsequent exposure of the other surface of the substrate by the upper exposure member 13. Alternatively, after one surface of the substrate on the upper and lower tables 21 is exposed by the upper exposure member 13, the substrate on the lower table 21 may be exchanged onto the upper table 11, so that the other surface of the substrate is exposed by the lower exposure member 23.

In the working condition that the substrates are two, after one side of the substrate positioned on the upper workbench 11 is exposed by the lower exposure piece 23 and one side of the substrate positioned on the upper workbench 21 is exposed by the upper exposure piece 13, the substrate positioned on the upper workbench 11 can be exchanged onto the lower workbench 21 and the substrate positioned on the lower workbench 21 is exchanged onto the upper workbench 11, so that the subsequent upper exposure piece 13 can expose the other side of the substrate originally positioned on the upper workbench 11, and the subsequent lower exposure piece 23 can expose the other side of the substrate originally positioned on the lower workbench 21.

S4, the upper stage 11 and/or the lower stage 21 are moved in a direction away from each other, and the other of the upper exposure member 13 and the lower exposure member 23 exposes the other surface of the substrate.

In the case where the substrate is one, for example: when the substrate originally on the upper stage 11 is exchanged onto the lower stage 21, the lower stage 21 moves leftward, and the upper exposure tool 13 exposes the other surface of the substrate on the lower stage 21 during the leftward movement. Alternatively, when the substrate originally on the lower stage 21 is exchanged onto the upper stage 11, the upper stage 11 is moved rightward, and the lower exposure member 23 may expose the other surface of the substrate on the upper stage 11 during the rightward movement.

In the case where the substrates are two, after the substrates on the upper table 11 are exchanged onto the lower table 21 and the substrates on the lower table 21 are exchanged onto the upper table 11, the lower table 21 is stationary, the upper table 11 can be moved rightward, and in the process of moving rightward, the other surface of the substrate on the upper table 11 is exposed by the second exposure member and the other surface of the substrate on the lower table 21 is exposed by the first exposure member. Alternatively, the upper table 11 is stationary, the lower table 21 is moved leftward, and during the leftward movement, the other surface of the upper substrate on the lower table 21 is exposed with the first exposure member, and the other surface of the upper substrate on the upper table 11 is exposed with the second exposure member. Alternatively, the upper table 11 is moved rightward while the lower table 21 is moved leftward, and the other surface of the upper substrate positioned on the lower table 21 is exposed by the first exposure tool while the upper table 11 and the lower table 21 are moved, and the other surface of the upper substrate positioned on the upper table 11 is exposed by the second exposure tool.

S5, the substrate is moved away from the upper table 11 and/or the lower table 21.

In the case where the substrate is one, for example: after the other surface of the substrate on the upper table 11 is exposed, the substrate on the upper table 11 may be carried back to the production line. Alternatively, after the other surface of the substrate on the lower table 21 is exposed, the substrate on the lower table 21 may be carried back to the production line; under the working condition that the substrates are two, after the exposure of the other surface of the substrate on the upper workbench 11 and the substrate on the lower workbench 21 is completed, the substrate on the upper workbench 11 can be carried to the production line again, and meanwhile, the substrate on the lower workbench 21 can be carried to the production line again. In this way, the entire exposure process of the exposure apparatus 1 can be completed.

As shown in fig. 2, the number of substrates is one, and in step S3, the method includes:

and S311, the upper adsorption member 12 moves downwards or the lower adsorption member 22 moves upwards to adsorb the substrate on the opposite workbench.

That is, in the process of exchanging the substrate on the lower table 21 onto the upper table 11, first, the upper suction member 12 moves downward, and when moving to contact the substrate, the upper suction member 12 is opened to vacuum-suck the substrate, and the second suction cup closes the vacuum to release the substrate while sucking the substrate, thereby completing the suction work of the upper suction member 12 on the substrate on the lower table 21; or, in the process of exchanging the substrate on the upper table 11 to the lower table 21, the lower suction member 22 is moved upward first, when moving to contact the substrate, the lower suction member 22 is opened to vacuum-suck the substrate, and the first suction cup closes the vacuum to release the substrate while sucking the substrate, thereby completing the suction work of the lower suction member 22 on the substrate on the upper table 11.

S312, the upper absorbing member 12 is contracted upward or the lower absorbing member 22 is contracted downward, and the upper table 11 or the lower table 21 absorbs the substrate.

That is, in the process of exchanging the substrate on the lower table 21 onto the upper table 11, after the upper suction member 12 moves down to suck the substrate, the upper suction member 12 contracts upward, when the substrate contacts the first suction cup, the first suction cup vacuum is opened to suck the substrate, and then the upper suction member 12 is closed to vacuum-release the substrate, at this time the upper suction member 12 releases the substrate, and the upper table 11 completes the suction of the substrate; or, in the process of exchanging the substrate on the upper table 11 to the lower table 21, after the lower suction member 22 moves up to suck the substrate, the lower suction member 22 is contracted downward, when the substrate contacts with the second suction cup, the second suction cup is opened to suck the substrate, then the lower suction member 22 is closed to vacuum release the substrate, at this time, the lower suction member 22 releases the substrate, and the lower table 21 completes the suction of the substrate.

As shown in fig. 2, two substrates are provided on the upper table 11 and the lower table 21, respectively, and in step S3, the method includes:

s321, the substrate on one of the upper table 11 and the lower table 21 is temporarily removed.

For example: when the substrate on the lower stage 21 is exchanged to the upper stage 11, the substrate on the upper stage 11 may be first transported leftwards by the first transporting member 15 and temporarily removed from the upper stage 11, so that the upper stage 11 may be used to adsorb the substrate on the lower stage 21.

S322, the adsorbing member corresponding to one of the upper table 11 and the lower table 21 adsorbs the substrate on the other of the upper table 11 and the lower table 21, and transfers it to one of the upper table 11 and the lower table 21.

For example: when the substrate on the lower table 21 is exchanged to the upper table 11, the substrate on the upper table 11 may be temporarily removed, the upper suction member 12 on the upper table 11 may be moved downward, when the upper suction member 12 is moved to contact the substrate on the lower table 21, the vacuum of the upper suction member 12 is opened to suck the substrate, then the second suction cup vacuum is closed to release the substrate, then the upper suction member 12 is contracted upward, when the substrate contacts the first suction cup, the first suction cup vacuum is opened to suck the substrate, then the upper suction member 12 vacuum is closed to release the substrate, and thus the substrate on the lower table 21 may be exchanged to the upper table 11.

S323, the temporarily removed substrate is transported to the upper end or the lower end of the other of the upper table 11 and the lower table 21.

For example: in the working condition that the substrate on the lower table 21 is exchanged to the upper table 11, after the substrate on the lower table 21 is exchanged to the upper table 11, the substrate which has been temporarily removed from the upper table 11 can be transported to the upper side of the lower table 21, so that the lower suction members 22 corresponding to the lower table 21 can easily suck and transfer the substrate.

S324, the suction member corresponding to the other of the upper table 11 and the lower table 21 sucks the temporarily removed substrate, and transfers it to the other of the upper table 11 and the lower table 21.

For example: after the substrate on the lower table 21 is exchanged to the upper table 11, the substrate of the upper table 11, which was temporarily removed previously, may be transported to above the lower table 21, and then the lower suction member 22 starts to move upward, and when the lower suction member 22 moves upward to contact with the substrate, the lower suction member 22 is opened to vacuum-suck the substrate, and then the lower suction cup 28 of the first transporting member 15 is closed to vacuum-release the substrate, and then the lower suction member 22 may drive the substrate to shrink downward, and when the substrate contacts with the second suction cup, the first suction cup is opened to vacuum-suck the substrate, and then the lower suction member 22 is closed to vacuum-release the substrate, so that the substrate on the upper table 11 may be exchanged to the lower table 21. In this way, the exchange between the substrates on the upper table 11 and the lower table 21 can be achieved.

Further, as shown in fig. 1 and 2, the exposure apparatus 1 further includes: the first and second alignment members 14, 24, after step S1, and before step S2, further comprise:

s10, the first alignment member 14 aligns one surface of the substrate on the lower table 21, and/or the second alignment member 24 aligns one surface of the substrate on the upper table 11.

The first alignment member 14 and the second alignment member 24 can play a role in alignment, and it should be noted that, the first alignment member 14 and the second alignment member 24 all pick points through MARK points on the substrate, and then calculate a specific position of the substrate in the system, and the alignment process is: since MARK picking points of the substrate are calculated by the first alignment member 14 and the second alignment member 24, the first alignment member 14 is required to pick the substrate on the lower table 21, and the second alignment member 24 is required to pick the substrate on the upper table 11.

In addition, since the substrates are transported to the upper stage 11 and the lower stage 21, respectively, and the two stages are at the loading and unloading stations, but not at the alignment stations, the MARK point of the substrate is not in the field of view of the first alignment member 14 or the second alignment member 24, and the alignment can be performed only when the MARK is relatively moved to the field of view of the first alignment member 14 or the second alignment member 24.

In addition, in the working condition of the two substrates, when the two substrates are respectively placed behind the upper workbench 11 and the lower workbench 21, the distance between the upper substrate and the second alignment member 24 is not equal to the distance between the lower substrate and the first alignment member 14, in order to realize that the first alignment member 14 and the second alignment member 24 can simultaneously align the two substrates, it is required that the first alignment member 14 and the second alignment member 24 can independently move back and forth and right and left, so that the MARK point of the upper substrate is in the field of view of the second alignment member 24, and the MARK point of the lower substrate is in the field of view of the first alignment member 14.

Under the working condition of one substrate, for example: after the substrate is transferred from the production line to the lower stage 21, the first alignment member 14 may be used to align the substrate, so as to ensure that one surface of the substrate is at a predetermined position, and after the alignment is completed, the lower stage 21 is moved leftward, and the upper exposure member 10 is used to expose the substrate.

Under the working condition of two substrates, when the upper workbench 11 moves left, the lower workbench 21 moves right, the two substrates are respectively conveyed to the upper workbench 11 and the lower workbench 21, then the upper workbench 11 can move right, one surface of the substrate positioned on the lower workbench 21 is aligned by utilizing the first alignment piece 14, and meanwhile, the second alignment piece 24 performs micro movement in the front-back left-right direction to a proper position, and one surface of the substrate positioned on the upper workbench 11 is aligned.

In addition, as shown in fig. 2, after step S3, and before step S4, further includes:

s30, the upper table 11 and/or the lower table 21 are moved in a direction away from each other, and the first alignment member 14 aligns the other surface of the substrate on the lower table 21, and/or the second alignment member 24 aligns the other surface of the substrate on the upper table 11.

Under the working condition of one substrate, for example: after the substrate on the lower stage 21 is exchanged to the upper stage 11, the lower stage 21 is moved out to the right, so that after the second alignment member 24 is moved to a proper position, the other surface of the substrate on the upper stage 11 can be aligned, and the other surface of the substrate is ensured to be at a predetermined position.

Under the working condition of two substrates, after the upper and lower substrates are exchanged, the upper table 11 is moved to the left to the alignment position, and the first alignment member 14 can align the substrates on the lower table 21. At the same time, the second alignment member 24 aligns the other surface of the substrate positioned on the upper stage 11 by adjusting to a proper position. Therefore, the other surfaces of the two substrates can be ensured to be at preset positions, and subsequent exposure of the other surfaces of the two substrates is facilitated.

Under the working condition of one substrate, for example: the lower table 21 can be moved out rightward, then the lower suction cup 28 vacuum on the second conveying member 25 is opened to absorb the substrate on the production line, then the third driving member drives the second conveying member 25 to the lower table 21, when the substrate reaches the position which is matched with the lower table 21 in a preset mode, the second suction cup vacuum is opened to absorb the substrate, and meanwhile the lower suction cup 28 vacuum of the second conveying member 25 is closed to release the substrate, so that the substrate can be moved onto the lower table 21.

Under the working condition of two substrates, the lower workbench 21 can be moved out rightwards, the upper workbench 11 is moved out leftwards, when the lower workbench 21 is moved out rightwards, the lower sucker 28 vacuum on the second conveying piece 25 is opened to absorb the substrates on the production line, then the third driving piece drives the second conveying piece 25 to the lower workbench 21, when the substrates reach the position which is matched with the lower workbench 21 in a preset mode, the second sucker vacuum is opened to absorb the substrates, and meanwhile, the lower sucker 28 vacuum of the second conveying piece 25 is closed to release the substrates, so that the substrates can be moved onto the lower workbench 21.

Also, when the upper table 11 moves out leftwards, the upper suction cup 27 vacuum on the first carrying member 15 is opened to suck the substrate on the production line, then the third driving member drives the first carrying member 15 to the upper table 11, when the substrate reaches the position which is matched with the upper table 11 in advance, the first suction cup vacuum is opened to suck the substrate, and meanwhile, the upper suction cup 27 vacuum on the first carrying member 15 is closed to release the substrate, so that the substrate can be moved onto the upper table 11.

Further, in the step of S5, it includes:

the first carrier 15 moves away from the substrate on the upper table 11 and/or the second carrier 25 moves away from the substrate on the lower table 21.

Under the working condition of one substrate, for example: after the other surface of the substrate on the upper table 11 is exposed, the first transporting member 15 is driven by the third driving member to a position matching with the substrate, then the upper suction cup 27 of the first transporting member 15 is opened to vacuum the substrate, the substrate is sucked, the first suction cup vacuum is closed to release the substrate, so that the substrate can be sucked onto the first transporting member 15, and then the first transporting member 15 is driven by the third driving member to transport the substrate from the left side or the right side onto the production line.
