## AI 摘要

地球上每一块AI芯片都需要一种单一的薄膜材料。GPU、TPU、定制ASIC。无一例外。全球98%的供应由一家日本化学公司控制。目前没有可投入生产的替代品。唯一的生产商产能已排期至2027年。正在提价。交货期超过6个月。NVIDIA如此担忧，以至于他们自行承担一半资本支出以扩建供应商的晶圆厂。关键词是“umami”。目前无人讨论此事。但很快人们就会开始关注。

## 正文

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
