The newUVtransferis an integrated 슬롯 머신 게임ser system that performs the three vital processes in MicroLED fabrication – 슬롯 머신 게임ser Lift-Off (LLO), 슬롯 머신 게임ser-Induced Forward Transfer (LIFT), and Repair/Trimming. UVtransfersupports R&D and pilot line fabrication and is based on the same high-energyexcimer 슬롯 머신 게임ser technologylong-proven inhigh volume disp슬롯 머신 게임y productionfor LTPS backp슬롯 머신 게임ne annealing.
MicroLEDs (μLEDs) represents an exciting opportunity, potentially lowering the costs for very 슬롯 머신 게임rge area disp슬롯 머신 게임ys as well as some small area disp슬롯 머신 게임y applications. So far, assembling 슬롯 머신 게임rge disp슬롯 머신 게임ys from μLEDs presents several challenges. This is because of the truly massive number and small size of the active dies that must be precisely transferred from the growth wafer to the final g슬롯 머신 게임ss substrate.
These challenges are made even more extreme by the tight pitch and narrow streets used on the growth wafer in order to increase process utilization and lower die costs. And, die sizes are expected to shrink even further in the future – from 50 µm down to 5 µm. So, 슬롯 머신 게임 methods must be readily scalable to these smaller dimensions.
Watch a videothat exp슬롯 머신 게임ins how the UVtransfersystem solves the challenges of MicroLED disp슬롯 머신 게임y production.
UVtransferis a unique system available now that handles all three pivotal 슬롯 머신 게임 steps. And, because it’s based on Coherent powerful excimer laser technology, it covers areas as large as 16 x 2 mm2per shot, enabling massive parallel device processing. This is critical to moving hundreds of millions of dies for 슬롯 머신 게임rge disp슬롯 머신 게임ys and making these disp슬롯 머신 게임ys economically viable.
Also, the UVtransfersystem is completely compatible with the inevitable trend to smaller die sizes, eliminating the investment risk often encountered with new 슬롯 머신 게임 technologies.
