History of Changes
Data correction: Seoul Economic Daily (Apr 23, 2026) reports Samsung will bring P4 to full operation within 2026, about six months ahead of the original schedule; P4 is currently running at half capacity, with temporary-use approvals targeted for July and November 2026. The record previously showed January 2026.
