1100nm Nanosecond laser
Laser Stealth Dicing is a non-contact cutting technique that can cut semiconductor materials accurately and efficiently. The wafer Stealth Dicing laser introduced by Precilasers has achieved high quality stealth dicing on a variety of wafer materials. The infrared laser’s pulse width and waveform can be adjusted, also feature with pulse width and repetition rate be adjusted continuouly, to achieve accurate processing of the wafer.
