Amid a global race for semiconductor leadership, an Aachen-based startup has raised €254.4mn for its chip technology in a big boost for the German as well as the European semiconductor sector. Brothers Daniel and Sebastian Schall launched Black Semiconductor in 2020, spinning it out from the University of Aachen. The startup is developing a new type of chip-connecting technology using graphene, a novel material discovered in 2010 by Andre Geim and Konstantin Novoselov.
