LG Innotek is building a new semiconductor substrate factory in Vietnam to accelerate its future growth. This strategic move is a direct response to the explosive demand for high-performance substrates, a critical component for the rapidly expanding AI industry.
The timing for this expansion is driven by clear market signals. The global AI boom, encompassing everything from massive data centers to on-device AI in our smartphones, requires increasingly sophisticated semiconductor packages. This has created a structural shortage of high-end substrates like FC-BGA. LG Innotek’s existing 'mother factory' in Gumi, Korea, is already operating at full capacity to meet current orders, making new production lines an urgent necessity.
Several key factors solidified the company's confidence in this large-scale investment. First, LG Innotek's strong financial performance, as seen in its Q1 2026 earnings, provides the necessary capital to fund the expansion. Second, the company has proven its technological prowess by recently unveiling next-generation substrate technologies, assuring customers of its capability to produce cutting-edge products. Third, the competitive landscape is favorable. With rivals focusing heavily on server-use substrates, LG Innotek sees an opportunity to strengthen its position in the mobile substrate market, improving its overall product mix and profitability.
Vietnam, specifically the city of Hai Phong, was chosen for its strategic advantages. The region is already a well-established hub for electronics manufacturing. LG Group companies and other global tech giants, like the semiconductor assembly firm Amkor, have a significant presence there. This existing ecosystem, often called a 'cluster,' reduces supply chain risks, ensures access to a skilled workforce, and streamlines logistics. Furthermore, supportive policies from both the Korean and Vietnamese governments create a favorable environment for this investment.
Ultimately, this new factory is a cornerstone of LG Innotek's vision to transform its package solutions division into a business with KRW 3 trillion in annual revenue by 2030. It's not just about adding capacity; it's about securing a pivotal role in the future of the AI and high-performance computing supply chain.
