Black Semiconductor

Black Semiconductor develops Integrated Graphene Photonics (IGP) technology, which places graphene-based optical modulators and detectors on the same wafer as electronic circuits. The stated aim is faster, lower-power chip-to-chip communication, with optical waveguides replacing copper connections.

The website describes the technology as aimed at data centers and AI and high-performance computing platforms, and states that the process is CMOS-compatible. It does not name specific customers or describe a revenue model. The company is building FabONE, a 300mm pilot fab for this technology.

Black Semiconductor was founded in 2020 by Daniel and Sebastian Schall, with headquarters in Aachen, Germany, and a second location in the Netherlands. In March 2025 it acquired Applied Nanolayers, a graphene specialist based in the Netherlands. The website reports €25.7M of private investment and a €228.7M IPCEI grant secured in 2024, and lists open roles in fab management, design enablement, product engineering, finance and procurement.

Product: Integrated Graphene Photonics (IGP) technology for optical and electronic integration on a single chip wafer, with a 300mm pilot fab under construction.
