Black Semiconductor

Black Semiconductor is a German technology company developing Integrated Graphene Photonics (IGP™), a way to bring high-speed photonics directly onto electronic chips. Founded by Daniel and Sebastian Schall, the company aims to address the limits of conventional electrical chip connections, which can restrict bandwidth, increase heat and energy use, and work over short distances.

Its technology combines electronics and graphene-based photonics on a wafer, allowing chips to process information electrically and communicate using light. Black Semiconductor says this approach can support faster, lower-latency data transfer, reduce energy consumption, and enable longer-distance connections through optical waveguides. The company also emphasizes integration with standard CMOS manufacturing processes, with the goal of making the technology suitable for scalable production.

Black Semiconductor is building FabONE, a facility in Aachen, Germany, for a scalable pilot line based on 300-millimeter wafer technology. Its work focuses on semiconductor connectivity for applications including data centers, where growing compute demand is putting pressure on existing chip-to-chip communication.
