SkyWater Florida and BRIDG Complete Phase One of Government-Funded IBAS Interposer Technology Development Program

Establishes capability to support bridge interposer fabrication to strengthen national security for critical emerging technologies

SkyWater Technology (NASDAQ: SKYT), the trusted technology realization partner and BRIDG, a not-for-profit, public-private-partnership for the fabrication of microelectronics, today announced completion of phase one of a DOD-funded Industrial Base Analysis and Sustainment (IBAS) technology development program. Through this program with BRIDG and imec, a world-leading research and innovation center in nanoelectronics and digital technologies, SkyWater has developed a baseline fabrication flow for silicon bridge interposers, which are increasingly used in heterogeneous integration applications.

The IBAS program’s goal is to establish a comprehensive domestic silicon interposer manufacturing capability, supporting several advanced electronic systems. Silicon interposers are used to integrate semiconductor devices into a highly compact and power efficient format, providing increased performance and capability. Versatile and compact, silicon interposers are quickly becoming one of the most popular choices for advanced packaging.

“Completing phase one of this IBAS program is a major milestone for BRIDG and its ecosystem of partners who are establishing capabilities to manufacture domestic, reliable, next-generation microelectronic systems utilizing advanced packaging solutions in an open foundry,” said Dr. John Allgair, BRIDG vice president of advanced systems integration. “As a U.S.-based advanced packaging hub, we look forward to continuing to drive domestic self-sufficiency and to supporting customers through our partnership with SkyWater.”

Elements of the phase one bridge interposer capability will also be used in subsequent phases of the silicon interposer development program, where through-silicon vias (TSV) and RF-enabling materials and devices will be incorporated. The technology is available to both government and commercial customers.

“We are excited to have the first phase of the development program complete. SkyWater and BRIDG can now support initial customer inquiries for the interposer design and fabrication. This is a significant step for the program, our site and our partnership with BRIDG,” said Dale Miller, SkyWater Florida vice president and general manager.
