SK Hynix Inc, South Korea’s No 2 chipmaker, has completed the construction of a new chip production line in the country in order to expand its memory business.

The world’ second-largest DRAM maker’s M16 chip fabrication plant is located at its main production base in Icheon, south of Seoul.

Since November 2018, SK hyinx has invested 3.5 trillion won ($3.1 billion) for constructing the project. When chip manufacturing equipment inside the plant is counted, its total investment reaches about 20 trillion won.

The new factory is its largest chip factory at 336 meters long, 163 meters wide and 105 meter high, which is equivalent to the height of a 37-story apartment building, reports Yonhap news agency.

The company plans to produce the fourth-generation 10-nanometer (1anm) DRAM products from the second half of this year using the equipment. The M16 is expected to begin its mass-production starting in June.
