UMC Reports First Quarter 2013 Results

Capacity[5] for Foundry Segment

[5]	Estimated capacity numbers are based on calculated maximum output rather than designed capacity. The actual capacity numbers may differ depending upon equipment delivery schedules, pace of migration to more advanced process technologies, and other factors affecting production ramp-up.

Capacity for the first quarter was 1,461K 8-inch equivalent wafers. The estimated capacity for the second quarter will increase to 1,537K 8-inch equivalent wafers, mainly owing to the full-quarter consolidation of Fab8N.
