Origin Story
Inversion Semiconductor was founded in 2024 by Rohan Karthik and Daniel Vega, who met through the Entrepreneur First program and later joined Y Combinator. Karthik, with a background in mechanical engineering and experience at Arm and CMR Surgical, brings expertise in system architecture and automation. Vega, a physicist with research experience at CERN and in particle accelerators for cancer treatment, leads the development of the novel LWFA light source. The idea emerged from combining their skills to radically improve lithography by shrinking particle accelerators to create brighter, tunable light sources, enabling faster and more precise chip manufacturing. Early traction includes prototype development and laser stability testing in a Y Combinator lab[1][2][5].
