01 ·Fabrication & Packaging·★ MEMBER·10 min read EUV Lithography — The Madness of Making 13.5nm Light Light at 13.5nm is absorbed by air and by every lens material there is. So why did the semiconductor industry build an entire industry around it? Tin plasma sources, optics with no lenses at all, and the cost arithmetic against multi-patterning — explained from zero. 02 ·Fabrication & Packaging·FREE·9 min read How Are Chips Made? From Silicon Wafer to Yield, Explained How chips are made: every GPU and phone processor starts as sand and passes through hundreds of printing steps. From the basic moves — lithography, etching, ion implantation — to the brute force of EUV and the yield math that makes big dies exponentially expensive, explained from zero.
