nx_litho_gate.nx

nx_litho_gate.nx -- GATE: the chip-fab litho twin, pinned to the real DIY frontier (CMU Hacker Fab). T1 PROCESS -- the 9-step recipe (clean->oxidize->coat->expose->develop->etch->dope->strip->metallize) completes -> a transistor. T2 YIELD -- Seeds model on a CMU-class small die = 943 permil (~94%, matching CMU Hacker Fab's real yield). T3 TRANSISTORS-- 952 transistors at ~10 um feature on the die (CMU Hacker Fab's real device count). T4 FRONTIER -- shrink feature 10 um -> 5 um -> 3808 transistors (4x): the path from a flip-flop toward a real CPU. T5 COST -- cost per WORKING chip = wafer cost / (dies * yield) = 53c. T6 LIAR-KILL -- skip the dope step -> NO transistor; a bigger die -> lower yield (769 permil). The physics bites. GREEN iff all. Sovereign nx_cc->nxasm. Fabricates the RV64IM CPU we designed in sim -> printing our own chips. expect_exit: 0 license_tier: ORIGINAL
