Breakthrough Technology of MicroLED Testing for Mass Production
Education:
Micro-LED has excellent technical advantage, and the manufacturing cost should be getting reduced recently. To be mainstream technology, the next bottle neck is the testing cost. The typical test approach on micro-LED is PL, AOI, EL and Diode Characteristic testing. PL and AOI tests are one of good approaches, but it is required to have EL test, Diode Characteristics test after them. Therefore, EL test and Diode Characteristics test efficiency improvement shall be must for upcoming mass production phases. To improve it, current issues of performance, accuracy, and throughput need to be solved to reach efficient manufacturing cost as entire test workflow. This presentation introduces testing workflow model and offers brand-new approach of the cost reduction on micro-LED wafer testing especially for Mass Production looming in front of us which has electrical/optical test embedded as single setup, super massive parallel test of electrical/optical test with excellent throughput.
