Doosan Tesna (131970), a company specializing in post-process testing for system semiconductors, is on an upward trend. Attention is focusing on the share price movements of Korean semiconductor-related companies as discussions on semiconductor industry cooperation between South Korea and Japan's Hokkaido expand.

As of the morning of the 12th, Doosan Tesna was trading at 129,500 won, up 4,200 won from the previous trading day, a gain of 3.35%.

■ A Specialist in Post-Process Testing for System Semiconductors

Doosan Tesna operates a testing business that inspects the performance and normal operation of products during the semiconductor manufacturing process. The semiconductor industry has a structure in which various technologies and companies are connected, from design and manufacturing to post-processing. Accordingly, the expansion of semiconductor production infrastructure and trends in international cooperation also need to be examined from the perspective of the post-process industry.

■ Government Holds First Semiconductor Industry Cooperation Exchange Event with Hokkaido

It is also noteworthy that the government is exploring the groundwork for industrial cooperation with Japan's Hokkaido in the semiconductor sector. On September 22, the Ministry of Trade, Industry and Energy held the 'Korea-Japan (Hokkaido) Semiconductor Industry Cooperation Exchange Event' in Seoul. This event was the first economic cooperation initiative between the ministry, Hokkaido regional government agencies, and business leaders, and the two sides explored the foundations for cooperation between Korea and Hokkaido, focusing on semiconductors and other future growth industries.

In particular, Hokkaido's efforts to foster its semiconductor industry are drawing attention. Hokkaido has recently begun in earnest to build an advanced semiconductor cluster centered on Rapidus, and efforts to create a semiconductor industry ecosystem, including attracting related companies, establishing research and development infrastructure, and cultivating talent, are also continuing.

The Ministry of Trade, Industry and Energy assessed that there is high potential for cooperation between Korea, which has built an industrial ecosystem based on world-class semiconductor manufacturing capabilities, and Hokkaido. This exchange event is significant in that it explored the possibility of semiconductor industry cooperation between the two sides expanding beyond existing manufacturing capabilities to future growth industries as a whole.

■ No Direct Order or Earnings Link Confirmed Yet

For post-process testing companies for system semiconductors like Doosan Tesna, the scale of semiconductor production and the direction of technological development in the industry are important factors in assessing the business environment. However, no direct business participation or order relationship between Doosan Tesna and this Korea-Japan semiconductor industry cooperation exchange event has been confirmed. Therefore, it is difficult to conclude that the government's promotion of international cooperation will lead to increased revenue or operating profit for Doosan Tesna.

With Doosan Tesna rising to 129,500 won, attention is also focusing on the growth potential of the post-process testing industry for system semiconductors, along with the company's future share price movements. In particular, whether semiconductor cooperation between Korea and Hokkaido will develop into concrete projects and how far the scope of cooperation in related industries will expand are key points to watch.
