Doosan Corp. bets $700 mil. on chip substrate material biz

Doosan Corp., the holding company of the Doosan Group, plans to invest 970 billion won ($702.6 million) in expanding its production capacity for copper clad laminates (CCLs). This significant investment will be utilized to increase both domestic and overseas production capacity within the company's electromaterials business unit. The approval of this investment was made by the company's board of directors on Thursday.

CCLs are a crucial material for advanced semiconductor substrates and printed circuit boards (PCBs), which are integral components in virtually all electronic devices. The demand for CCLs has remained robust in recent months, as the market for the material continues to witness strong growth due to the persistent demand-supply imbalance in the broader semiconductor value chain.

This investment represents the largest in Doosan Corp.'s history and constitutes roughly 8 percent of its total equity capital. The company intends to allocate 420 billion won specifically towards expanding its domestic production lines for CCLs, which are used in optical transceivers. These devices play a vital role in data communication networks, further highlighting the strategic importance of this expansion plan for Doosan Corp.
