TipWhy This Matters

Hua Hong’s FIRST Wuxi 12-inch fab — the line that broke ground 2 March 2018 and took its first wafers 17 September 2019 — which this tracker had missed entirely while covering the newer Fab 9 (Phase II) and Phase 3. This is also a naming correction: Wikipedia and secondary sources label the Wuxi site ‘Fab 7’; the $6.7B Phase-II fab is Fab 9. Design capacity grew from the original 40,000/month (phase 1, $2.5B of a ~10-year $10B site plan) to ~95,000/month installed, running above 100% utilization through 2025.

Chinese name: 华虹半导体（无锡）有限公司 (Huáhóng Bàndǎotǐ (Wúxī))

What does this facility make?

12-inch power semiconductors for EVs, PV, and industrial applications — IGBTs, MOSFETs, BCD analog — plus eNVM and RF platforms.

Why does it matter?

Fab 7 is where China’s 12-inch power-semiconductor migration started; its >100% utilization and the group-wide 2026 8-inch price hikes (>10%) define the supply picture for domestic EV power electronics. The Wuxi campus’s three-way split (Fab7 / Fab9 / Phase3) is why this tracker keeps per-phase entries.
