About Inversion Semiconductor
Summary
Inversion Semiconductor builds lithography machines for advanced chip fabrication. Its core innovation is a miniaturized particle accelerator, shrunk by a factor of one thousand, that generates a high-power light source to pattern transistors at smaller scales than current equipment allows. The machine doubles transistor density and triples throughput, replacing existing lithography tools for chipmakers pushing transistors to their physical limits.
Go-to-market
Inversion Semiconductor targets semiconductor fabs seeking to manufacture the most advanced chips, with a focus on restoring that capability to Western markets.

Manufacturing the most powerful chips, 15x faster
Inversion Semiconductor is developing the next-generation chip fabrication machine, to create the most powerful chips 15x faster. Our vision is to reshore advanced chip fabrication capabilities in the West. We're building a lithography machine. Lithography uses light to pattern circuit features on silicon. We're scaling transistors to their physical limits by shrinking particle accelerators 1000x, to create a high power light source. Using our light source we will double transistor density for a given numerical aperture and 3x throughput.

Score every batch against your own thesis
GPAgent's sourcing agent reads every company in a batch, scores each one against your fund's thesis in a private workspace, and lines up the founders worth meeting before Demo Day. You decide who to contact. Your scores, notes, and pipeline never appear on these pages.
