TAIPEI/SEOUL -- Taiwan Semiconductor Manufacturing Co. is the heavyweight champion of contract chipmaking. But the company, which controls half of the business worldwide, is now facing a serious challenge from Samsung Electronics, its archrival in South Korea.
Samsung is using its huge war chest to catch up on the next battleground: 5G, the next-generation mobile communication standard. But TSMC's lead may be insurmountable, given the stellar finance and business strategy of founder Morris Chang.
