What Inversion Semiconductor does
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.

Inversion Semiconductor
Manufacturing powerful chips 15x faster
We're building a next-gen lithography machine that patterns silicon chips using a new, powerful light source. We created a particle accelerator scaled down 1000x to generate light intense enough to shrink circuit features beyond current limits. This lets chip fabs double transistor density and triple throughput, making chips up to 15x faster.
We live in San Francisco and plan to base the company here after YC.
San Francisco gives us access to top-tier engineering talent and venture capital networks which are critical for scaling our hardware startup.
