TipWhy This Matters

SMIC’s smallest of the four 2020-2022 mega-fab JVs (中芯深圳, 55.05% SMIC-owned), a $2.35 billion 28nm foundry with the Shenzhen municipal government.

Chinese name: 中芯深圳 (Zhōngxīn Shēnzhèn)

What does this facility make?

12-inch (300mm) wafers at the 28nm node.

Why does it matter?

28nm is the workhorse node for automotive, IoT, and power-management chips — the segment of demand China’s fabs can serve without needing export-controlled EUV lithography. Chinese industry trade coverage confirms the fab entered production by the end of 2022, on schedule against its original target.
