Black Semiconductor

Black Semiconductor is a technology company focused on graphene integrated photonics. It develops photonic circuits directly fabricated on silicon-scale electronics, enabling chip-to-chip communication at higher data transfer rates, over longer distances, with reduced energy consumption. By combining electronics and photonics on a single wafer, the company aims to overcome bandwidth and energy limits of traditional copper interconnects. The approach uses graphene to connect electrical signals and light, offering CMOS-compatible processing that fits into existing chip production pipelines. This enables faster, more energy-efficient data transfer and scalable integration for data centers and other computing applications. The company is advancing a scalable 300mm wafer pilot line and has established fabrication facilities in Aachen, Germany (FabOne) to support scalable production.
