UNITED SEMICONDUCTORS, LLC

United Semiconductors, LLC specializes in the design, development, and production of advanced semiconductor crystals for extreme-environment applications, with deep expertise in physical vapor deposition, bulk crystal growth, and in-space manufacturing of III-V binary and ternary compounds. The company leverages proprietary techniques to fabricate high-purity aluminum nitride and semimetal-semiconductor composite crystals tailored for electro-optical infrared systems and space-based instrumentation. Their technical differentiation lies in scaling single-crystal growth processes under microgravity and vacuum conditions, enabling the production of defect-minimized materials critical for next-generation sensors, power electronics, and space-qualified photonic devices. This focus on novel crystal synthesis for mission-critical aerospace systems sets them apart in the niche field of space-adapted materials engineering. The contractor has established a consistent relationship with NASA and the Department of Defense, delivering SBIR-phase research and development solutions focused on in-space materials fabrication. For NASA, they advance autonomous manufacturing capabilities for space-based semiconductor production, while for the DoD, they enable the domestic supply of high-performance infrared-grade crystals for defense electro-optical systems. Their work is mission-driven, aligned with strategic imperatives in space sustainability and sovereign semiconductor sovereignty. Their primary industry focus is research and development in physical and engineering sciences, specifically advancing semiconductor materials science beyond terrestrial constraints. They operate at the intersection of materials engineering and space systems, serving the defense, aerospace, and advanced sensor markets with a vertically integrated approach to crystal growth and validation. As a Women-Owned Small Business certified under the 8(a) program and designated as a Woman-Owned Business, United Semiconductors, LLC brings a unique perspective to federal R&D procurement. Based in Los Alamitos, California, the company positions itself as a specialized innovator in high-value, low-volume semiconductor manufacturing for national security and space exploration missions.
