MC 4: Inspection Technologies in Micro and MiniLED Manufacturing

MicroLED manufacturing involves the production of millions of LED devices, and the transfer of these LEDs onto the display substrates.

Given the imperfect yield at nearly all stages of manufacturing from growth to transfer to bonding, a critical part of the manufacturing strategy is inspection and repair.

In this class, you will learn about:
Challenges in microLED production and challenges in identifying and repairing defects at various stages of production
PL and EL measurements
MicroLED sorting, binning and tagging
Manufacturing-ready technologies for inspection and repair of microLED at all stages of the production from wafer growth to transfer to bonding
