Norwegian startup, Lace Lithography, has raised $40 million to replace the use of chip-making light with helium atoms. The company uses a beam the width of a single hydrogen atom to etch chip features up to ten times smaller than current extreme ultraviolet lithography can achieve. The current machine used by ASML, which produces the most advanced chips, costs upwards of $350 million. Lace's Series A was led by Atomico, the European venture firm, with participation from Microsoft’s M12, Linse Capital, Nysnø, a Norwegian state climate investment company, and the Spanish Society for Technological Transformation. The firm has already developed prototype systems and is targeting a test tool in a pilot chip fabrication plant, or fab, around 2029.
