US specialty foundry SkyWater Technology Inc. has completed the first phase of a government-funded program to develop the capability to make silicon interposers.
The work has been done at SkyWater’s facility in Kissimmee, Florida, with BRIDG, a not-for-profit, public-private-partnership for the fabrication of microelectronics and research institute IMEC.
SkyWater is part of a trusted foundry network being developed in the US strengthen national security for critical emerging technologies. Through the government-funded program SkyWater has developed a fabrication flow for silicon interposers, which are increasingly used in heterogeneous integration – chiplet-style – applications.
John Allgair, BRIDG vice president of advanced systems integration, said: “As a US-based advanced packaging hub, we look forward to continuing to drive domestic self-sufficiency and to supporting customers through our partnership with SkyWater.”
Development will continue with the use of through-silicon vias (TSV) and RF-enabling materials and devices. The technology is available to both government and commercial customers.
