In a massive strategic bet on the next wave of tech demand, South Korea’s leading semiconductor testing provider, Doosan Tesna, is pouring over KRW170 billion (approx. US$120 million) into new testing equipment. Industry observers believe this huge capex plan is a direct move to prepare for a sharp surge in orders from its primary customer, Samsung Electronics, which is set to ramp up production of CMOS image sensors (CIS) for Apple.
