There is a single thin-film material required by every AI chip on earth. GPUs， TPUs， custom ASICs. All of them. 98% of global supply controlled by one Japanese chemical company. Zero production-ready alternatives. One producer fully booked through 2027. Raising prices. Lead times past 6 months. NVIDIA is so scared they're paying half the capex to expand supplier fabs themselves. The keyword is "umami". Nobody's talking about this. They will be in about
