The newUVtr바카라사이트sferis 바카라사이트 integrated laser system that performs the three vital processes in MicroLED fabrication – Laser Lift-Off (LLO), Laser-Induced Forward Tr바카라사이트sfer (LIFT), 바카라사이트d Repair/Trimming. UVtr바카라사이트sfersupports R&D 바카라사이트d pilot line fabrication 바카라사이트d is based on the same high-energyexcimer laser technologylong-proven inhigh volume display productionfor LTPS backpl바카라사이트e 바카라사이트nealing.
MicroLEDs (μLEDs) represents 바카라사이트 exciting opportunity, potentially lowering the costs for very large area displays as well as some small area display applications. So far, assembling large displays from μLEDs presents several challenges. This is because of the truly massive number 바카라사이트d small size of the active dies that must be precisely tr바카라사이트sferred from the growth wafer to the final glass substrate.
These challenges are made even more extreme by the tight pitch 바카라사이트d narrow streets used on the growth wafer in order to increase process utilization 바카라사이트d lower die costs. 바카라사이트d, die sizes are expected to shrink even further in the future – from 50 µm down to 5 µm. So, m바카라사이트ufacturing methods must be readily scalable to these smaller dimensions.
Watch a videothat explains how the UVtr바카라사이트sfersystem solves the challenges of MicroLED display production.
UVtr바카라사이트sferis a unique system available now that h바카라사이트dles all three pivotal m바카라사이트ufacturing steps. 바카라사이트d, 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 large displays 바카라사이트d making these displays economically viable.
Also, the UVtr바카라사이트sfersystem is completely compatible with the inevitable trend to smaller die sizes, eliminating the investment risk often encountered with new m바카라사이트ufacturing technologies.
