# Chinese Semiconductor Supply Chain Entities

Every entry below is a lead to investigate, not a fact to cite. Your job is to verify,
contradict, or discover what's missing. China's supply chain is evolving fast, so entries
here may be outdated. STAR Market IPO prospectuses are the richest public source for
supplier details.

## Entity List Exposure Risk (assess before reporting)
Companies at highest risk of future US Entity List designation:
1. SMEE — lithography is #1 target
2. AMEC — advanced etch at leading nodes
3. Naura — breadth of equipment portfolio
4. Piotech — ALD for advanced nodes
5. NSIG/Zing — enabling advanced fab capacity

**Already on Entity List:** SMIC (added Dec 2020), YMTC (added Dec 2022)

## Key Intelligence Notes
- **STAR Market (688xxx) IPO prospectuses** disclose TOP-5 SUPPLIERS BY NAME with amounts. This is the richest public source for Chinese semiconductor supply chain mapping.
- **EastMoney (东方财富)** aggregates all Chinese broker reports — free PDF downloads.
- **Big Fund (大基金)** investment portfolio is partially opaque. Phase I, II, III total >$100B.
- Chinese companies frequently claim technology capabilities that exceed verified production quality — triangulate claims against actual fab qualification status.
