Abstract
Description
Technical Field
[0001] The present invention relates to the field of semiconductor processing, and particularly to a alignment synthesis system and an alignment synthesis method. Background Art
[0002] With the continuous progress of science and production technology, more energy-efficient and bendable OLED screens were introduced in previous years. Compared with OLED screens, LCD screens are too thick, have a lower contrast ratio, and a slow response speed; although OLED screens have many advantages, their lifespan is not long enough and the resolution is relatively low. Considering the advantages and disadvantages of the former two, the concepts of MicroLED and MiniLED were proposed in recent years. MiniLED is to miniaturize the direct-lit LED backlight module and make the panel color palette very good and the contrast ratio very high; however, this approach increases the usage of LEDs, the cost is very high, and it is not easy to promote and use on a large scale.
[0003] The difference between MicroLED and OLED is that it does not use organic substances for manufacturing, but a new material, gallium nitride. Therefore, it will not have the image burnin (commonly known as screen burn-in phenomenon) like OLED even after long-term use. Like OLED displays, MicroLED displays have perfect black, excellent color, and almost perfect viewing angles, and they are brighter, less prone to aging, and in the long run, cheaper than OLEDs. MicroLED TVs are also based on a modular system, allowing users to customize the screen size. Currently, compared with OLEDs, the production cost of MicroLED is still too high, and the existing mass transfer solutions lead to too high production costs. Summary of the Invention

[0071] Example 1
[0072] See also Figure 1 , is a schematic diagram of the structure of a counter-position synthesis system provided by an embodiment of the present invention. Figure 1 As shown, the alignment synthesis system is used to synthesize LED wafer units using initial wafer units. Figure 2 and Figure 3As shown, the initial chip unit Carrier1 includes a first chip unit RRR, a second chip unit GGG, a third chip unit BBB, and a fourth chip unit WWW of Carrier2, where W is a blank chip; the alignment synthesis system includes a laser detection unit, an adsorption table, and a moving component.
[0073] The moving component is used to move the first chip unit RRR to the laser working module 1, and the adsorption table is used to adsorb the first chip unit RRR and move the fourth chip unit WWW to the lower part of the adsorption table, so that the first chip unit RRR and the fourth chip unit WWW are aligned and synthesized into a first intermediate chip unit RWW;
[0074] The moving component is further used to move the second chip unit GGG to the laser working module 1, and the adsorption table is used to adsorb the second chip unit GGG, so that the second chip unit GGG and the first intermediate chip unit RWW are aligned and synthesized into a second intermediate unit RGW;
[0075] The moving component is further used to move the third chip unit BBB to the laser working module 1, and the adsorption table is used to adsorb the third chip unit BBB, so that the third chip unit BBB and the second intermediate unit RGW are aligned and synthesized into an LED chip unit RGB.
[0076] According to a specific embodiment of the present disclosure, the alignment synthesis system further includes a manipulator 14, a left pre-calibration module 9, a left pre-calibration stage 7, a right pre-calibration module 8, and a right pre-calibration stage 6.
[0077] According to a specific embodiment of the present disclosure, the alignment synthesis system includes a first left stage 3, a second left stage 5, the left pre-calibration stage 7, the left pre-calibration module 9, the left loading and unloading module 11, and the left magazine switching module 13 arranged on the left side along the operation flow direction, and a first right stage 2, a second right stage 4, the right pre-calibration stage 6, the right pre-calibration module 8, the right loading and unloading module 10, and the right magazine switching module 12 arranged symmetrically on the right side along the operation flow direction. Among them, the first left stage 3 and the first right stage 2 are arranged at one end close to the laser working module 1, and the left magazine switching module 13 and the right magazine switching module 12 are arranged at one end far from the laser working module 1.
[0078] Specifically, among the above components, the laser working module 1 is lifted and lowered by a galvanometer under the drive of a motor lead screw module. The pre-calibration stage is a fixed stage with a backlight. When there is a chip on the stage, the backlight is turned on to cooperate with the camera on the pre-calibration module to capture the MARK points on the chip and determine the position status coordinates of the chip. The pre-calibration module is a motor lead screw module that drives the pre-calibration camera to move back and forth. When there is a chip that needs to be pre-calibrated, the module moves the camera directly above the pre-calibration stage to pre-align and position the chip. After completion, it returns to the initial position to avoid interference. The loading and unloading module is a motor lead screw module with an arm with adsorption holes fixed on the slider. The module controls the arm to extend into and out of the lower part of the product in the cassette. Then, the cassette switching module descends to transfer the chip to the arm for adsorption and then takes out the chip. The cassette switching module is a module with lifting and left-right movement functions. The lifting is a motor lead screw module, and the left-right switching is a rack and pinion device. The position where the arm of the loading and unloading module picks up the material can be selected by controlling the lifting and left-right switching of the cassette. It should be noted that the above-mentioned motor lead screw modules and rack and pinion devices can be replaced by devices such as synchronous belts, chains, linear motors, and cylinders with corresponding functions, and should not be construed as a limitation on the possible real-time structures. Figure 2 In it, Carrier1 is fixed on the adsorption stage at the top of the upper alignment device, and Carrier2 is on the stage of the six-axis motion platform.
[0079] The alignment and synthesis system provided in this embodiment solves the problem of transferring gallium nitride inorganic light-emitting units from Carrier 1 to Carrier 2 during the "mass transfer" process of MicroLED. A chip manufacturing method disclosed by the present invention improves production efficiency by optimizing the chip manufacturing sequence. It optimizes the alignment accuracy and full automation degree of the mass transfer and synthesis process of LED chip units in the Micro LED processing technology.
[0080] Next, the specific processes of multiple alignment and synthesis methods that can be implemented by the above alignment and synthesis system will be explained respectively using Embodiments 2-5.

[0109] After Carrier 1 (RRR①) completes pre-alignment, the manipulator 14 transports Carrier 1 (RRR①) to the right carrier stage 2 of Carrier 1 according to the position information of the pre-alignment, and the carrier stage docks and adsorbs it. At the same time, Carrier 2 (WWW①) on the left pre-loading stage 7 completes pre-alignment, and the manipulator 14 transports it to the right carrier stage 4 of Carrier 2.

The manipulator 14 transports Carrier 2 (RWW①) to the left loading and unloading module 11. The left loading and unloading module 11 sends Carrier 2 (RWW①) into the empty position of the cassette, then takes out Carrier 2 (WWW④). At the same time, the manipulator 14 transports Carrier 2 (WWW③) on the left pre-alignment carrier 7 to the right carrier 4 of Carrier 2, and then transports Carrier 2 (WWW④) on the left loading and unloading module 11 to the left pre-alignment carrier 7.

[0115] The manipulator 14 transports the Carrier 2 (RWW②) to the left loading and unloading module 11. The left loading and unloading module 11 sends the Carrier 2 (RWW②) into the empty position of the magazine, and then takes out the Carrier 2 (WWW⑤). At the same time, the manipulator 14 transports the Carrier 2 (WWW④) on the left pre-calibration stage 7 to the left Carrier 2 stage 5, and then transports the Carrier 2 (WWW⑤) on the left loading and unloading module 11 to the left pre-calibration stage 7. After three laser processing operations are completed, the state of the Carrier 2 (WWW③) changes to Carrier 2 (RWW③), and the state of the Carrier 1 (R_._①) on the adsorption stage of the laser working module 1 changes to Carrier 1 (_._._①). The right Carrier 2 stage 4 carrying the Carrier 2 (RWW③) moves to the unloading position. The manipulator 14 transports the Carrier 2 (RWW③) to the left loading and unloading module 11. The left loading and unloading module 11 sends the Carrier 2 (RWW③) into the empty position of the magazine, and then takes out the Carrier 2 (WWW⑥). At the same time, the right Carrier 1 stage 2 takes away the Carrier 1 (_._._①) on the adsorption stage of the laser working module 1 and moves to the unloading position. The left Carrier 1 stage 3 carrying the Carrier 1 (RRR②) moves under the laser working module 1. After alignment, the Carrier 1 (RRR②) is adsorbed on the adsorption stage of the laser working module 1. Then, the Carrier 2 (WWW④), Carrier 2 (WWW⑤), Carrier 2 (WWW⑥), and all subsequent Carrier 2 (WWW) repeat the actions of Carrier 2 (WWW①), Carrier 2 (WWW②), Carrier 2 (WWW③); the Carrier 1 (RRR②) and all subsequent Carrier 1 (RRR) repeat the actions of Carrier 1 (RRR①) until the states of all Carrier 2 (WWW) change to Carrier 2 (RWW).
[0116] The above steps complete the transfer of red grains R. The transfer of green grains G and blue grains B is consistent with the red grain transfer step. Repeat the above steps to complete the transfer of green and blue grains, transfer the grains on Carrier 1 (GGG) to Carrier 2 (RWW), change the state of Carrier 2 (RWW) to Carrier 2 (RGW), and then transfer the grains on Carrier 1 (BBB) to Carrier 2 (RGW), change the state of Carrier 2 (RGW) to Carrier 2 (RGB), until all Carrier 2 (WWW) wafers in the material box are processed. Take away the material boxes filled with Carrier 1 (_._._, _._._, _._._) and Carrier 2 (RGB, RGB, RGB) on the right material box switching module 12 and the left material box switching module 13.
[0117] In summary, the main synthesis process of the alignment synthesis system provided in this embodiment is: provide a blank wafer WWW to receive the R, G, and B grains that are removed by the laser from the first wafer RRR, the second wafer GGG, and the third wafer BBB. For example, simplify WWW into a 9 by 9 square, that is, the horizontal and vertical coordinates are both 1-9, and according to the color formation principle of the display screen, WWW, R, G, and B grains are arranged alternately. After the alignment is completed, rows 1, 4, and 7 of WWW receive the R grains from the second wafer RRR, and rows 2, 5, and 8 of WWW receive the G grains from the second wafer GGG, and finally rows 3, 6, and 9 of WWW receive the B grains from the second wafer BBB. In this way, WWW can be transformed from a blank wafer into a Carrier 2 with alternating R, G, and B grains.
[0118] The alignment synthesis method provided in this embodiment first replaces one grain in all fourth wafer units with a red grain R, and then replaces the green grain G and the blue grain B in sequence, thereby realizing a fully automatic cyclic alignment synthesis scheme and optimizing the processing flow of mass transfer.
