Description
Technical Field
The invention relates to the field of semiconductor manufacturing equipment, in particular to crystal grain transfer equipment and a crystal grain transfer process thereof.
Background
In the field of display technology, micro display technologies that are currently in mass production include HTPS TFT LCDs based on crystal glass, DLPs based on silicon wafers, and the like. Since the OLED technology has the limitation defects of light emitting efficiency, operating temperature range, and lifetime, the inorganic Micro LED will be the main technology of the future Micro display in the long term. As the conventional flat panel display technology and application gradually enter the mature period, the development of display application will step to the fields of wearing or virtual reality and augmented reality, and the micro display technology based on the wafer process is more suitable for emerging applications due to the influence of factors such as contrast value, panel precision and power saving. The technology for manufacturing Micro LED arrays on wafers is mature, so that mass production of Micro displays using the technology is expected, but when the technology is expanded to be applied to general flat panel displays, the huge transfer efficiency of crystal grains becomes the biggest technical bottleneck. How to effectively transfer the LED crystal grains to the glass or plastic substrate becomes a key factor for the large-scale development and popularization of the Micro LED technology.
In the process of developing a production line of a crystal grain transfer automation device, a carrier plate is required to load crystal grains to adapt to material transfer and loading and unloading in the automatic production process, and a single carrier plate is used for bearing a plurality of crystal grains to ensure the efficiency in the production process. Therefore, the problems of automatic storage of the carrier plate, cooperative action of carrier plate storage and taking and placing actions, and guiding limitation and fixation in the carrier plate storage process need to be solved in the crystal grain transfer process, so as to ensure the stability of the crystal grain position.
In addition, the problems of transfer and taking and placing of the carrier plate need to be solved in the production process; meanwhile, as the situation that the incoming and outgoing directions of the carrier plate are inconsistent possibly exists between the storage part and the crystal grain transfer production part, the problem of position or angle adjustment during transfer between different stations of the carrier plate needs to be solved; in addition, since the carrier is loaded with a plurality of crystal grains, the problems of position stability and accuracy of the carrier during the transfer process need to be solved.
In the process of developing a production line of a crystal grain transfer automation device, a carrier plate is required to load crystal grains to adapt to material transfer and loading and unloading in the automatic production process, and a single carrier plate is used for bearing a plurality of crystal grains to ensure the efficiency in the production process. The core process section in the grain transfer equipment is a grain transfer process, and the following technical problems need to be solved aiming at the grain transfer process: 1. the crystal grain to be transferred is generally placed on a carrier plate with a blue film horizontally clamped in the middle, the crystal grain needs to be transferred to a horizontal glass or plastic carrier plate, and the automatic bearing problem of the carrier plate and the automatic coordination problem between the taking and placing actions of the carrier plate and the carrier plate need to be solved in the crystal grain transfer process. 2. The crystal grain transfer process requires that the crystal grains on the blue film carrier plate are accurately transferred to the glass carrier plate, so that the automatic adjustment of the relative position or angle of the two carrier plates needs to be solved before the crystal grains are transferred, and the accuracy of the crystal grain transfer is ensured. 3. When the crystal grains are transferred, the blue film carrier plate and the glass carrier plate are required to be tightly adhered to each other so as to reduce the moving path of the crystal grains transferred between the two carrier plates and improve the position precision, and the glass carrier plate is made of easily damaged materials, so that the problem that the surfaces of the two carrier plates are scratched or damaged due to contact is required to be solved. 4. The damage of the crystal grain, the blue film or the lower glass carrier plate caused by excessive pushing is easy to occur in the downward probing process of the probe. 5. The blue film carrier of the crystal grain to be transferred is made of a flexible material and has certain internal elasticity, when the probe pushes one crystal grain on the blue film, the acting force of the probe received by the crystal grain is transmitted to the blue film, so that the blue film is partially protruded and deformed downwards from the original plane state along the crystal grain, and the situation can cause the position of other crystal grains around the crystal grain to deviate, or the position of other crystal grains around the crystal grain can not be completely restored to the original plane state after the blue film is deformed, so that the situation that the crystal grains drop is caused. 6. Based on the above situation, the blue film is upwards adsorbed by adopting vacuum negative pressure in the probe downward probing process, and the problem of cooperation between the movable probe and the adsorption cavity needs to be solved. 7. In addition, because the probe moves the crystal grains down at high speed in batches, the probe needs to be replaced frequently, and therefore the problem of rapid disassembly and assembly of the probe needs to be solved.
