'Doosan Tesna' Official Launch... "Will Become the Number One Partner in System Semiconductors"

Doosan Completes Acquisition of Tesna, No.1 in Semiconductor Testing Field

[Asia Economy Reporter Oh Hyung-gil] Doosan Group has completed the acquisition process of Tesna, the number one company in the semiconductor testing field, and has set sail in the semiconductor business.

Doosan announced on the 27th that it has completed the acquisition process of Tesna and officially launched 'Doosan Tesna.' Last month, Doosan signed a stock purchase agreement (SPA) to acquire all shares held (38.7%), including common and preferred stocks, from AITree LLC, the largest shareholder of Tesna, for 460 billion KRW.

Tesna is a company specializing in testing, a post-process in system semiconductor production, and currently holds the number one market share in wafer testing.

Wafer testing is the process of receiving circular wafers engraved with 1,000 to 10,000 semiconductor chips in an unprocessed state, conducting electrical, temperature, and functional tests to determine whether they are good products.

The main test products of Doosan Tesna are camera image sensors (CIS) that convert light into electrical signals, application processors (AP) that implement various smartphone functions on a single chip, and radio frequency (RF) communication chips. It is explained that CIS testing has top-tier competitiveness among peer companies.

Doosan Tesna aims to solidify its leading position in the testing field and secure packaging technology that assembles semiconductors after wafer processing, establishing itself as a representative Korean semiconductor post-process specialist company.

A Doosan Tesna official said, "As global competition for system semiconductor supremacy intensifies and large-scale investments are being made in all process areas such as design and manufacturing, strengthening the competitiveness of post-process companies is also required," adding, "Doosan Tesna will play the role of the number one partner in domestic system semiconductors."
