Mosaic Awarded $1 Million from DBX Challenge

Mosaic Microsystems LLC proudly announces its success in winning a $1.0 million award as one of the competitors in the Defense Business Accelerator (DBX) Microelectronics Challenge. This strategic initiative, aimed at revolutionizing how the Department of Defense catalyzes commercial technology development, is both a significant milestone for Mosaic Microsystems and the start of an interesting new era in the broader defense technology landscape.

Mosaic Microsystems emerged as a finalist from a pool of over 270 applications, presenting their “Thin Glass Substrates for Advanced Microelectronics Packaging” solution at the Defense TechConnect Innovation Summit on November 28. A distinguished panel of industry, government, and investment experts evaluated the pitches, ultimately awarding seven winners a combined total of $10 million in funding.The DBX Microelectronics Challenge, a new program fostering innovation within the Department of Defense, serves as a catalyst for industrial base growth and private investment stimulation. By prioritizing commercial technology development, the challenge aims to expedite solution development and enhance the longevity of suppliers, ushering in a new era of collaboration between industry, government, and investment sectors.

The DBX challenge is a collaborative effort, merging the electronics industry expertise of the U.S. Partnership for Assured Electronics (USPAE) and the Department of Defense’s Manufacturing, Capability Expansion, and Investment Prioritization Directorate (MCEIP). Tactical support from Advanced Technology International (ATI), specifically the TechConnect division, further bolsters the challenge’s impact on the selected winners and the broader community.

Mosaic Microsystems showcased their innovative thin glass technology for advanced microelectronics packaging. The applications span various domains, including RF, compute, integrated photonics, and biomedical devices. Mosaic is prototyping thin glass with multi-layer interconnects, along with copper-filled through-glass vias connecting front to back of the glass, and will rapidly move these to production for both defense and commercial industries.

“We are pleased to have been selected for this prestigious award,” says Christine Whitman, CEO of Mosaic Microsystems. “The Defense Business Accelerator recognition validates our business strategy for expansion and underscores the critical role of Mosaic’s glass technology.”

Brittany Hedrick Joins Mosaic Microsystems as Integration Engineer

Mosaic Microsystems proudly announces the addition of Brittany Hedrick as Senior Engineering Manager.

DoD Awards Contract to Mosaic Microsystems

DoD Awards Contract to Mosaic Microsystems to work with AIM Photonics on cutting-edge glass-based electronic and photonic interposers

Mosaic Microsystems, a pioneering leader in advanced microelectronics glass packaging technology, is delighted to announce the successful award of a Phase II Small Business Innovation Research (SBIR) contract by the Department of Defense (DoD). This award reflects Mosaic Microsystems’ commitment to pushing the boundaries of innovation and its dedication to enhancing national defense capabilities.

Under this Phase II SBIR effort, Mosaic Microsystems will develop ultra-thin glass interposers with through-glass via (TGV) technology. These cutting-edge interposers will serve as the foundation for a high-speed packaging solution designed for analog and digital electronics and photonics. As part of this transformative initiative, in collaboration with the American Institute for Manufacturing Integrated Photonics (AIM Photonics), Mosaic Microsystems’ will demonstrate the integration of fiber optics, waveguides, and photonic integrated circuits (PICs) with glass.

Advanced application-specific integrated circuit (ASIC) or PIC-based systems currently rely on a silicon (Si) substrate for the electronic interposer or electronic and photonic interposer (respectively) and an organic laminate substrate for RF signals, power, and control. Mosaic Microsystems’ effort will leverage the capabilities of AIM Photonics’ Test, Assembly and Packaging (TAP) facility to develop photonics-enabled glass interposers. Mosaic’s glass interposers promise greater efficiency, superior electrical and thermal isolation, and more compact packaging solutions compared to the conventional packages.

This innovative approach will apply not only to defense technology but also to commercial applications. By introducing thin glass photonic interposers, Mosaic Microsystems seeks to demonstrate substantial cost savings, reduced size and weight, and enhanced overall performance over current solutions. These advantages are expected to have far-reaching implications for next-generation digital communications and have the potential to shape the future of 5G and ‘Next G’ technologies.

“This DoD SBIR Phase II contract supports our team’s ability to drive technological innovations in the important area of photonics packaging,” said Shelby Nelson, Chief Technology Officer and Co-Founder at Mosaic Microsystems. “We are thrilled to collaborate with AIM Photonics TAP on this venture, as we help build the future of electronics, photonics, and communications technologies.”
