Doosan Tesna is making a large investment to expand its semiconductor testing infrastructure.

According to industry sources on the 29th, the company disclosed that it decided to acquire about 190.9 billion won worth of tangible assets, including semiconductor test equipment, from Teradyne (TERADYNE (ASIA) Pte.,LTD) and SEMES, among others. 

Doosan Tesna said it will bring in the equipment in stages through the end of this year and continue expanding its semiconductor testing capacity.

The company also increased a previously disclosed equipment investment plan of about 171.4 billion won, announced in October last year. Citing rising product demand, it raised the planned amount to about 205.3 billion won. Counterparties include Advantest Corporation and SEMES, among others.

In addition, Doosan Tesna disclosed it will fully resume investment in a new facility for its second plant in Pyeongtaek, after adjusting the start date in line with market conditions. The investment totals about 230.3 billion won, with completion targeted for November 2027.

A Doosan Tesna official said the asset purchases and plant construction are “proactive steps to secure a foundation for future growth,” adding they are expected to play an important role in boosting revenue and operating profit over the mid to long term.
