Recently, ON Semiconductor announced that it has completed the acquisition of a 20% stake in an 8-inch wafer fab of Fujitsu Semiconductor. At present, the total share of ON Semiconductor is 60%, and the name of the factory will be changed from Fujitsu Semiconductor to ON Semiconductor.

The factory is located in Aizu-wakamatsu City, Japan, and is a shared factory between Fujitsu Semiconductor and ON Semiconductor. In 2014, ON Semiconductor and Fujitsu Semiconductor reached an agreement under which ON Semiconductor acquired a 10% stake in Fujitsu's 8-inch wafer fab and began production of wafers in June 2015. In April 2018, ON Semiconductor increased its ownership interest in the plant to 40%. Now, ON Semiconductor has taken over most of the plant's business and operations by repurchasing a 20% stake. In addition, ON Semiconductor also said it will increase its proprietary shares to 100% in the first half of 2020. At the same time, ON Semiconductor also stressed that this additional capacity will allow ON Semiconductor to continue to expand its business to meet forecasting needs and increase supply chain flexibility.

In recent years, ON Semiconductor has acquired more capacity and management rights in the plant through the acquisition of equity, highlighting the rising demand for capacity of ON Semiconductor, and indirectly indicating that the market for analog electronics is accelerating. According to the data, ON Semiconductor has a 3% market share in the analog semiconductor market and a market share of over 40% in the automotive image sensor market.
