UMC Reports Second Quarter 2015 Results

Capacity[4]for Foundry Segment

Wafer shipments increased 3.7% quarterly to 1,536K in 2Q15. Quarterly capacity grew to 1,659K, resulting in an overall utilization rate of 94% for the quarter.

Capacity[4] for Foundry Segment

Overall capacity in the second quarter was 1,659K 8-inch equivalent wafers. Deployment of 28nm capacity at Fab12A increased quarterly capacity from 183K in 1Q15 to 198K in 2Q15. Capacity expansion for 40nm at Fab12i continued, bringing the quarterly capacity from 139K in 1Q15 to 144K in 2Q15. Projected capacity during the third quarter will grow by 1.6% to 1,685K 8-inch equivalent wafers due to ongoing 28nm capacity deployment at Fab12A and continuous 8" expansion at Fab8N.
