FPCNs are issued at least 90 days prior to implementation of the change. ON Semiconductor will consider this change approved unless specific conditions of acceptance are ## **DESCRIPTION AND PURPOSE:** This is the Final Notification by ON Semiconductor notifying customers of its plan to add Niigata Fab (Japan) as the qualified wafer source for Small Signal General Purpose Transistors and Bias Resistor Transistors. The Niigata Fab facility is an ON Semiconductor owned wafer fab that has been producing products for ON Semiconductor. Several existing technologies within ON Semiconductor’s product families are currently sourced from Niigata Fab. ON Semiconductor Niigata Wafer Fab is an internal factory that is TS16949, ISO-9001 and ISO-14000 certified. Qualification tests are designed to show that the reliability of the transferred devices will continue to meet or exceed ON Semiconductor standards.
