Our company took over inherited the Mie 300mm fab from Fujitsu Semiconductor Limited. The fab started operations in 2005.
From the beginning of operations, this fab has been mainly providing foundry services for the advanced logic LSIs, and has established manufacturing, information management, quality control, and customer support systems for the foundry business In accordance with ISO14001, we pursue "Green Fab".
According to the ISO9000 series and automotive ISO/TS16949 certifications, we have established quality assurance and control systems.. Additionally, we have been making our utmost efforts towards safety and quality improvements.

For our earthquake management, we are the first semiconductor fab in the world to adopt a hybrid seismic isolation structure. Three types of seismic isolation systems have been placed between the building and its foundation, which under normal conditions minimize the effect of fine vibrations, allowing us to achieve a stable supply for our customers.
Seismic Isolation System: "Laminated rubber supports"
A rubber bearing that absorbs vibrations and attenuates the swaying of the building.
Seismic Isolation System: "Solid sliding supports"
A Teflon-coated sliding face that slides horizontally and absorbs the building's vibrations.
Seismic Isolation System: "Oil damper"
This restricts the range of lateral movement of the Solid sliding supports bearing.
In preparation for a stoppage of the supply of city gas in the event of a large scale disaster, we have installed a liquefied natural gas (LNG) satellite base. As a result, in the event of a stoppage of gas, we are able to supply LNG using the satellite base and tanker vehicles. We continue to further strengthen our fab infrastructure against such disasters.
As a countermeasure against instantaneous voltage drops or power failures, we have adopted NAS (Sodium – Sulfur) batteries. This enables the continuous operation of a stable fab.
