The South Korean firm is taking on bigger rival Taiwan Semiconductor Manufacturing Co Ltd (TSMC) in the contract manufacturing business, where it competes for orders from customers such as Qualcomm Inc .
“This new production facility will expand Samsung’s manufacturing capabilities,” the company said in a statement on Thursday.
Samsung is targeting the second half of next year to start producing advanced 5 nanometre chips, using extreme ultraviolet (EUV) technology, on the added line in its plant in Pyeongtaek city, within a two-hour drive of the capital, Seoul.
“This is Samsung’s effort to narrow the gap with TSMC, as it still lags behind TSMC in the contract chip making market,” said Park Sung-soon, an analyst at Cape Investment & Securities.
TSMC, the world’s biggest contract chipmaker, plans to build a $12 billion factory in the U.S. state of Arizona, it said last week.
Samsung now operates five foundry lines in South Korea and one in the United States.
Last year, Samsung said it planned to invest 133 trillion won ($107.97 billion) in non-memory chips through 2030, comprising 73 trillion won for domestic R&D and 60 trillion won for production infrastructure.
This month, President Moon Jae-in said he aimed to nurture the non-memory industry in his agenda to foster economic growth.
South Korea’s chip exports for the first 20 days of May soared 13.4%, while exports of mobile devices and cars collapsed 11.2% and 58.6% respectively, customs data showed.
