The ferroelectric materials used for FRAM affects the reliability issue. Data retention and fatigue characteristics can lead polarization charge decrease. Fujitsu Semiconductor shows the resistance reliability of FRAM throgh evaluating Test Element Group (TEG) and products.
Fujitsu controls whole processes of FRAM: research, development and mass production. Since the first mass production in 1999, we have been producing and shipping a great number of FRAM products. Controlling the whole FRAM production within the group including wafer and assembly processes, makes stable supply possible. This also achieves the delivery of high quality FRAM products with our own technology such as Fujitsu original ferroelectric film forming technology, ferroelectric capacitor processing technology and degradation(canused by wiring and ILD
Established in October 1984. Mie plant is one of the leading plants of Fujitsu Semiconductor, which works for Logic LSI production (Front-end process). Its property in Kuwana, MIE, spreads over 307,000m3. There are 200mm and 300mm line for wafer production since April 2005 and another 300mm line since 2007. Also, the Mie plant is voluntarily working for "green" activities such as hybrid seismic isolation structure, NAS batteries and Zero emission.
Established in October 1997. The Nantong plant is a Fujitsu's joint company in China. It focuses on assembly and testing for general-use microcontrollers and linear integrated circuit for analogue.
