MicroLED End-to-End Process Control

MicroLED displays offer many key performance benefits such as brightness, contrast, power consumption and lifetime, however, cost and manufacturing maturity remain barriers to wide market acceptance. Improved yield through better process control provides a pathway to lower costs and manufacturing readiness. In this paper we discuss yield and end-to-end process control from epitaxy and microLED patterning, driver IC (optional), backplane, mass-transfer, and bonding.
