Previously, such LEDs were diced together with the sapphire substrate and used in the form of chips.

By epitaxially growing GaN on a sapphire substrate, light-emitting diodes (LEDs) that produce UV, blue and green light can be fabricated 1. Q: I must admit I’ve not heard of Bolite before. Laser lift-off (LLO) is a process of separating layers on a substrate. With these experiences in both semiconductor laser processing and MEMS processing, I decided to start Bolite and build a team to develop state-of-the-art laser solutions for microprocessing applications. I was also a vital member of the team that successfully demonstrated the world’s shortest wavelength diode laser at the time, a 250 nm UV laser for military applications. Army Research in collaboration with Oracle. I was a research engineer at Xerox PARC and helped develop surface micromachined microspring interconnects in a project funded by the U.S.

Cheng, can you please tell us a little about your background, prior to starting Bolite? Cheng to learn more about this trending subject and the company he started.

The title of his talk was “Laser Processing Applications for the Manufacturing of Mini and MicroLED Displays.” Since it was presented in Mandarin only, caught up with Dr. Bowen Cheng, was invited to present at the recent Touch Taiwan 2021 Conference in April. The founder and General Manager of Bolite Optoelectronics, Dr.
