TipWhy This Matters

SK Hynix’s Chongqing back-end (2013 agreement, mass production 2014, phase-2 2019, ~$1.2B cumulative) — the assembly/test counterpart to its Wuxi DRAM and Dalian NAND fabs, and the reason the Korean memory maker’s China exposure is not only about wafer fabs.

Chinese name: 爱思开海力士半导体（重庆）有限公司 (Àisīkāi Hǎilìshì Bàndǎotǐ (Chóngqìng))

What does this facility make?

Packaging and test of NAND flash modules/SSD components.

Why does it matter?

As of August 2026 SK Hynix is reportedly weighing options incl. selling a stake (~$3B valuation, possible Chinese fund buyers) while keeping the site running — the first major case of a Korean memory back-end in China facing a divest-or-double-down decision under tool-control pressure.
