Glass fabrication solutions for MEMS and RF applications

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.

Micro 3D printing for emerging MEMS and microfluidics applications

Boston Micro Fabrication (BMF) is a leader in microscale 3D printing systems aimed towards short-run industrial production of micro-sized devices. The newest printer in BMF’s line enables larger build volumes, faster printing speeds, and supports the use of industrial-grade materials. BMF’s 3D printers provide MEMS designers with an alternative to micromachining processes that require multiple steps and can only create low-aspect ratio devices. Unlike surface micro machining, BMF’s tools can create micro-devices with high aspect ratios. Plus, with its faster build times, BMF’s printers also offer advantages over bulk micro machining, which is slow to etch and requires bonding to form complex structures. We recently spoke with BMF’s CEO John Kawola about the company’s history, recent accomplishments, current traction in the marketplace, and plans for the future.

MEMS manufacturing: Mosaic Microsystems, Axus Technology collaborating on thin glass wafer processing solutions

Axus Technology, a provider of CMP, wafer thinning, and wafer surface processing solutions for semiconductor applications, is working with Mosaic Microsystems to build the supply chain for thin glass and through-glass via (TGV) processing and heterogeneous microelectronic packaging. Overcoming the challenges of handling, thinning, and cleaning <200 um thick wafers cost effectively prior to metallization is a key element in providing a robust, scalable process. Mosaic’s thin glass solutions provide key performance characteristics such as low loss, CTE match, environmental stability, and cost-effectiveness particularly desirable for 5G applications, as well as for MEMS and sensors for the internet of things (IoT). The company’s proprietary temporary bond technology supports thin glass substrates during downstream processing. This thin glass handling technology allows the supply chain to leverage the existing infrastructure for next generation microelectronics and photonics applications.
