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

Doosan Corp., the holding company of Doosan Group which also operates an electromaterials business, will invest 970 billion won ($702.6 million) to expand its production capacity for copper clad laminates (CCLs), a key material for advanced semiconductor substrates. Doosan Corp. said in a regulatory filing Thursday that its board approved investment to expand the domestic and overseas production capacity of its electromaterials business unit. Under the plan, the company will invest 970 billion won by Dec. 31 next year to expand its production capacity in Korea and overseas. The investment is the largest in Doosan Corp.’s history and accounts for about 8 percent of its equity capital. CCL is a key material used in advanced chip substrates and printed circuit boards (PCBs) found in virtually all electronic devices. The market for the material has remained strong in recent months as demand continues to outpace supply across the broader semiconductor value chain. Doosan Corp. will spend 420 billion won to expand its domestic production lines for CCLs used in optical transceivers — device
