The Department of Defense today announced an award of $14.4 million via the Defense Production Act Investment (DPAI) Program to 5N+ Semiconductors (5N Semi) to sustain and expand the capability to produce germanium substrates used in solar cells for defense and commercial satellites. This effort supports the 2024 National Defense Industrial Strategy to continue and expand support for domestic production within the resilient supply chains strategic priority area.
"Space-based capabilities are vital to U.S. national security," said Dr. Laura Taylor-Kale, Assistant Secretary of Defense for Industrial Base Policy (ASD(IBP)). "This effort will feed supply chains that support the space power ecosystem while also helping ensure the long-term business viability of the U.S. defense industrial base for space-qualified germanium wafers."
The award facilitates the enhancement of space-qualified germanium wafer manufacturing capabilities, vital for solar cells utilized in commercial and national security satellites. It involves upgrading and expanding production facilities and tools while minimizing production variability. Additionally, the initiative will address process integration with solar cell producers' evolving germanium substrate requirements. The effort also includes improvements in germanium sourcing, recovery, and refining. Finally, it supports product diversification to ensure long-term merchant supplier business viability. The technical effort will take place at 5N Semi's facility in St. George, Utah and is planned to last four years.
This is the latest of 13 awards made by the DPAI program across multiple areas totaling $322 million since the beginning of fiscal year 2024. DPAI is overseen by the ASD(IBP)'s Manufacturing Capability Expansion and Investment Prioritization (MCEIP) Program, in the Office of the Deputy Assistant Secretary of Defense for Industrial Base Resilience.
