At IMID, AP Systems of Korea said that it can create fine metal masks (FMM) with an ultra-short pulse layer with 1,000 ppi and the company said that this could be extended as high as 1,170ppi according to a report from OLEDNet. The firm depends on being able to eliminate the burr that is usually created around the holes in the mask which normally gets created when a laser is used to create the holes. The company’s technology is also said to be able to control the taper angle of the holes.
The AP Systems Korona FMM system can support substrates of up to 300mm x 300mm with position accuracy of 1μm and has 50 laser beams.
