The companies expect to use phase two of Fab 5 primarily for technology transitions of existing Yokkaichi wafer capacity. The new cleanroom will provide the space needed for additional equipment required for transitioning the wafer capacity in Fab 3, Fab 4 and phase one of Fab 5, to next generation 2D NAND technologies and to early generations of 3D NAND technology.
Fab 5 will have an earthquake absorbing structure and is designed to minimize environmental impact. Extensive use of LED lighting throughout the facility and up-to-date energy-saving production facilities, along with full and effective use of waste heat, are expected to reduce CO2 emissions to a level 13 percent lower than for Fab 4.
Fab 5 phase 2 will have an automated product transportation system and quake-absorbing structure and will be designed to minimize environmental loads. Deployment of LED lighting and up-to-date energy-saving production facilities, along with full and effective use of waste heat, are expected to cut CO2 emissions by 13% compared with Fab 4.
