The world talks about TSMC, NVIDIA, and multi-billion-dollar EUV machines. But no chip can exist without another pile of "snacks" almost nobody sees — photoresist, polishing slurry, specialty gases, and metal sheets purified to nine-nines — fed onto the wafer drop by drop across hundreds of steps. Together they're a market of just ~$67 billion — a fraction of the chip value they create — yet some have only 2–3 makers on Earth, and almost all of them are in Japan. This is the truest chokepoint of the chip era.
