Presenter: Francois Henley, President and CEO Tesoro Scientific and QMAT, Inc
Abstract: There are three main problems with microLED commercialization:
- The high cost and variability of the microLED devices and print processes
- The lack of manufacturing technologies necessary to test, transfer, and interconnect these devices reliably on the display surface.
- Low microLED efficiency at the 5-50um form factor.
To address these issues, QMAT is developing a novel epi wafer technology that improves microLED efficiency, uniformity and manufacturability. Tesoro Scientific is developing compatible mass-production capable equipment designed to functionally inspect the microLED devices to identify known good die and then very rapidly remove the devices using a laser ablation process. The presentation will describe this manufacturing process combining an epi wafer with integrated test and release layers with functional test & mass-transfer equipment to realize high-yield microLED mass-production.
