Lux Semiconductors has raised $2.1M in total across 2 funding rounds.
Lux Semiconductors develops metal core substrates and interposers for system-in-package (SiP) designs. Their technology significantly improves thermal dissipation and reduces warpage in microelectronics. Leveraging a patent-pending recrystallization process, Lux creates thin-film semiconductors and smart metal modules, enabling reduced size, weight, power, and high-density routing for advanced chiplets.
The company originated from the ambition to build the first ubiquitous flexible semiconductor platform, dubbed 'Wafer 2.0'. This vision stemmed from leveraging metal as a foundational material for next-generation semiconductor substrates. This innovative approach aims to redefine microelectronics architecture through advanced material science in packaging.
Lux Semiconductors' solutions serve demanding applications in defense and aerospace, evidenced by awards from the US Air Force and Space Force. Its vision centers on pioneering flexible, high-performance semiconductor platforms. By re-imagining wafer technology with metal-based solutions, Lux aims to enable compact, powerful, and thermally efficient electronic systems.

Lux Semiconductors is a microelectronics startup founded in 2017 and headquartered in Albany, New York, specializing in advanced system-level packaging for semiconductors. The company develops a proprietary System-on-Foil platform using metal substrates and interposers, enabling heterogeneous integration of chiplets for System-in-Packages (SiP) and Multi-Chip Modules (MCM). This addresses key challenges like thermal dissipation, warpage, high bandwidth, low latency, and small form factors in applications from defense to AI, autonomous vehicles, and healthcare.[2][3][5]
Lux serves defense contractors, energy sectors, and commercial industries needing high-performance, lightweight electronics. It solves limitations of traditional silicon wafers and organic substrates—such as fragility, heat trapping, and poor scalability—by providing flexible, single crystal-like thin-film metal platforms that support 3D stacking of processors, memory, sensors, RF, displays, and more. With prototypes at Cornell NanoScale Facility and enrollment in ORNL’s Innovation Crossroads, Lux has raised $6M in grants and $2.3M in seed funding, showing early momentum toward a $6M Series Seed round.[1][5][6]
Lux Semiconductors emerged in 2017 amid the slowdown of Moore’s Law, which historically doubled transistor counts every two years but now shifts focus to advanced packaging like chiplets on high-performance substrates. Co-founders Luke McMahon (CEO) and Graeme Housser (CTO), both based in Ithaca, NY, identified the need for metal-based substrates to replace heat-trapping organics, leveraging metal's superior thermal management and warp resistance.[5][6]
The idea gained traction through the ORNL Innovation Crossroads program, where Lux developed roll-to-roll prototyping for flexible semiconductors, enhancing crystal quality and scalability. Early milestones include 6 patents on chip carriers and electromagnetism, a 4,100 sq ft lab in Ithaca, and support from top defense contractors like Lockheed Martin. This evolution from R&D to prototype positions Lux as a "More than Moore" pioneer.[1][2][6]
Lux rides the chiplet revolution and "Moore’s Law of packaging," as transistor scaling slows and heterogeneous integration becomes essential for performance gains in AI, edge computing, and defense. Timing aligns with demands for ultra-thin, flexible electronics beyond rigid silicon wafers (95% of devices today), fueled by market forces like U.S. onshoring, supply chain resilience, and SWaP-constrained applications in autonomous systems and renewables.[1][6]
By pioneering metal substrates, Lux influences the ecosystem shift to SiP/MCM, enabling lightweight, high-function devices and reducing reliance on Asian manufacturing. Its ORNL ties and grants amplify U.S. advanced packaging innovation, competing with firms like Bridge Semiconductor and Microchip.[2][6]
Lux is poised for growth via its $6M Series Seed, commercial partnerships in AI/healthcare, and manufacturing scale-up from Ithaca prototypes. Trends like 3D integration and DoD funding will propel it, potentially capturing share in the $50B+ advanced packaging market as chiplets dominate.
As a "Wafer 2.0" enabler, Lux's metal platforms could redefine flexible semiconductors, delivering the ubiquitous platform for next-gen electronics from its high-level vision of low-cost, high-performance thin-films.[1][5]
