His work has implications for the efficiency and effectiveness of LED manufacturing.

Latest Patents

Dima Simonian holds a patent for an underfill process for flip-chip LEDs. This technique utilizes compression molding to encapsulate an array of flip-chip LED dies mounted on a submount wafer. The process allows liquid underfill material to fill the gap between the LED dies and the submount wafer, which is then hardened through curing. The cured underfill material is subsequently removed using microbead blasting, and the exposed growth substrate is eliminated from the LED dies by laser lift-off. This innovative method supports the brittle epitaxial layers of each LED die during the lift-off process, significantly reducing fabrication time and accommodating a variety of materials with different viscosities.
