Startup Substrate Could Enable the Age of XRay Lithography for sub-Nanometer Chips
by Brian Wang from NextBigFuture.com on (#72V3Q)
Startup Substrate is building next-generation semiconductor fabs using advanced X-ray lithography. This goes beyond extreme ultraviolet 13.5 nanometer wavelengths down to 0.01 nanometers. At the core of Substrate's technology is a custom particle accelerator which propels electrons (produced by an unknown emitter) to near the speed of light using radio-frequency cavities. As these electrons pass ...
