WebAnother use of laser ablation in LED industries is wafer dicing. As GaN is normally grown on sapphire, and sapphire is the second hardest material in the world, a diamond blade is the only viable tool for mechanical dicing. On the other hand, a diamond blade often deviates from its intended dicing direction when the blades are thin, causing WebThere are primarily two types of laser oscillation for processing: continuous wave (CW) oscillation and pulse oscillation. The pulse oscillation process can minimize the thermal effect and is mainly used for laser dicing in …
