Plans to shrink particle accelerators by 1,000x could speed chipmaking by 15X - Inversion Semiconductor proposes 'tabletop' particle accelerators with petawatt lasers


Y-Combinator-backed startup eyes powerful laser wakefield accelerator for advanced lithography techniques.

Among all makers of litho systems, only ASML has successfully created EUV light to print the smallest chip features — but one startup has a radical new idea to change the status quo. Inversion Semiconductor, a San Francisco startup backed by venture capital firm Y Combinator, plans to develop a light source based on a compact particle accelerator, which it claims would be 33 times more powerful than ASML's existing technology and could pave the way for producing finer chip features. They have also partnered with the Lawrence Berkeley National Laboratory and the BELLA Center to collaborate on the BELLA-LUX project, focusing on refining laser stability and improving the generation of suitable light for semiconductor use.
