摘要

一篇研究指出，磷化铟（InP）供应链的结构性瓶颈并非市场关注的铟价，而是高纯磷的供应。关键供应商是日本公司NCI和Rasa，它们提供用于InP原料的高纯红磷。这种材料直接影响到晶体生长良率和认证。

客观事实
  • 磷化铟供应链的结构性瓶颈是高纯磷
  • NCI和Rasa是日本高纯红磷关键供应商
NCI Rasa InP 高纯磷

原文

My friend GSR wrote a really good piece. He found a new bottleneck.

The market is overly focused on indium prices, but the more structural bottleneck in the InP supply chain is qualified high-purity phosphorus.

NCI and Rasa are key Japanese suppliers of red phosphorus for InP feedstock, or 6N/7N high-purity red phosphorus. Once again, obscure Japanese companies I had never heard of are controlling the bottleneck lol.

This material is not just a simple commodity input. It is a process-sensitive material directly tied to crystal growth yield and qualification.
