Mosaic Microsystems, located in Rochester, New York, was founded in 2016 to provide a manufacturing solution for inserting glass as a substrate into advanced packaging for next generation products. The core technology is a temporary bond technique that was developed and licensed from Corning, and enables handling and processing of thin glass substrates within a high-volume production environment. The company believes this is a key enabler for insertion of thin glass because their solution employs the use of existing semiconductor processing equipment.
Mosaic’s initial products are thin glass wafers temporarily bonded to a silicon or other type of wafers with or without through glass vias and with or without metallization. The company has recently been awarded multiple SBIR and STTR grants. This includes efforts to collaboratively develop ultra-low loss solutions for next-generation radar arrays with the University of Florida, establish low loss mobile electronically steerable antenna (ESA), heterogeneous integration, and more recently to develop low loss integrated passive devices (IPDs) with commercial partners. The awards are sponsored by the Air Force Research Lab (AFRL) under the AFWERX Agility Prime Open Topic as well as the National Science Foundation. We recently spoke with Christine Whitman, Mosaic’s Chairman and CEO about the company’s history, technology origins, recent and planned milestones, vision, emerging applications, and marketplace dynamics. Mosaic raised $2 million from Corning and BlueSky Capital in May 2020.
