Exclusive: Samsung Electronics and SK Hynix are evaluating chipmaking equipment from China's Advanced Micro-Fabrication Equipment for possible use at their Chinese factories, as the South Korean firms hedge against the risk of tighter US export controls

What happened

Samsung Electronics and SK Hynix are reviewing chipmaking tools made by China's Advanced Micro‑Fabrication Equipment to see if they can be used in their Chinese factories, aiming to reduce exposure to possible tighter U.S. export restrictions.

Confirmed

Global impact / market context

If U.S. rules limit the sale of advanced semiconductor gear to South Korean firms, these companies could lose access to critical equipment. Turning to a Chinese supplier helps keep production running and limits supply‑chain disruption.

Analyst inference

The move comes amid escalating U.S.–China tech tensions that have already pressured equipment makers and chipmakers. A shift toward Chinese‑made tools could reshape demand patterns in the global semiconductor‑equipment market.

Analyst inference

What to watch

1. Any official U.S. export‑control announcements targeting South Korean chip firms, which would confirm whether the firms’ hedging is necessary. Proposed
2. Progress of Samsung and SK Hynix’s trials with Advanced Micro‑Fabrication Equipment, indicating whether Chinese tools meet performance and reliability standards. Proposed
3. Reactions from other chipmakers about sourcing equipment from China, which could signal broader industry shifts away from traditional Western suppliers. Proposed
