In 4Q20, wafer shipments increased 1.7% QoQ to 2,293K, while quarterly capacity remained flat at 2,311K. As a result, the overall utilization rate in 4Q20 was 99%.

Capacity4

Total capacity in the fourth quarter totaled 2,311K 8-inch equivalent wafers. We foresee in the first quarter, that capacity will decline to 2,280K 8-inch equivalent wafers, mainly reflecting the product mix changes at WTK and Fab 8A.
