(1) One 6-inch wafer is converted into 0.5625(6 2 /8 2 ) 8-inch equivalent wafer; one 12-inch wafer is converted into 2.25(12 2 /8 2 ) 8-inch equivalent wafers. Capacity total figures are expressed in 8-inch equivalent wafers.
 
4 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.
