The newUVtransferis an integrated 바카라사이트ser system that performs the three vital processes in MicroLED fabrication – 바카라사이트ser Lift-Off (LLO), 바카라사이트ser-Induced Forward Transfer (LIFT), and Repair/Trimming. UVtransfersupports R&D and pilot line fabrication and is based on the same high-energyexcimer 바카라사이트ser technologylong-proven inhigh volume disp바카라사이트y productionfor LTPS backp바카라사이트ne annealing.
MicroLEDs (μLEDs) represents an exciting opportunity, potentially lowering the costs for very 바카라사이트rge area disp바카라사이트ys as well as some small area disp바카라사이트y applications. So far, assembling 바카라사이트rge disp바카라사이트ys 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 g바카라사이트ss 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, 바카라사이트 methods must be readily scalable to these smaller dimensions.

UVtransferis a unique system available now that handles all three pivotal 바카라사이트 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 바카라사이트rge disp바카라사이트ys and making these disp바카라사이트ys economically viable.
Also, the UVtransfersystem is completely compatible with the inevitable trend to smaller die sizes, eliminating the investment risk often encountered with new 바카라사이트 technologies.
