| Tin droplets hit by lasers expand into disks |
62,000 liquid hot tin droplets per second, 92 electron volts of photon energy, 1 micrometer laser pre-pulse, 1 micrometer laser rarefaction disk flattening pulse, then big dog 100KW CO2 laser 10 micrometer main pulse hits the tin disk creating tin ion plasma expanding into tiny fart pulse.
Each ionized tin atom photon excited then upon relaxing emits 13nm deep extreme ultraviolet light, mirror bounced around mirror optics onto laser etched nickel metal masks containing the individual layer information for the chip of which they are 100-300 layers requiring the same number of masks & scanning stages, chemical etching, photopolymers, resists, solvents, acids, bases, ion bombardment, testing & verification, wafer separation, chip testing, chip mounting, chip packaging, final package IC testing, then boxing or tray sorting to sell retail or for bulk to OEM integration into desktops, laptops, tablets, smartphones or similar, like an Apple Watch.
We are talking about Chip Fab's core lithography equipment, mainly focusing on the light source & how liquid tin droplets moving hundreds of miles per hour are precious hit by 3 different laser pulses to make extreme UV light for the multilayer mirror optics projection system that puts mask information onto the wafer in a stepping machine moving blurry fast 24/7 chip production output, making transistors the most manufactured thing in the world.
