Taiwan’s legacy chipmakers, once dominant in the production of mature node chips, are grappling with increased competition from Chinese foundries that are rapidly expanding their market share. The shift began in 2015 when Taiwan’s Powerchip Technology entered a deal with China’s Hefei city to establish a foundry, Nexchip. Initially hoping to access the promising Chinese market, Powerchip now faces Nexchip as a major competitor, leveraging Beijing’s support and steep price discounts. This rivalry is most prominent in the $56.3 billion market for 28-nanometer chips, which are commonly used in sectors like automotive and display panels.
Chinese foundries, including Nexchip, Hua Hong, and SMIC, have aggressively expanded production capacities and undercut Taiwanese prices, further intensifying competition. The increased Chinese capacity has prompted concerns in Taiwan’s chip industry, with Powerchip and other Taiwanese companies like UMC and Vanguard International now focused on more advanced or specialized chip technologies.
Taiwanese chipmakers are struggling to maintain their foothold in the mature node segment as Chinese firms benefit from substantial state backing and lower margins. According to TrendForce, in 2024, China is projected to control 34% of global legacy chip production, surpassing Taiwan’s 43% share by 2027. The situation is made worse by the U.S. trade tensions, with U.S. President Donald Trump proposing up to 100% tariffs on semiconductors produced outside the U.S., which could impact Taiwanese exports.
Chinese foundries have become more aggressive in their efforts to capture business from Taiwanese clients. Many Chinese customers, particularly in consumer sectors like display panels, are increasingly opting to use Chinese fabs, following Beijing’s push for domestic supply chain localization. Taiwanese chip designers have acknowledged that they must adapt to survive, with some already shifting focus to more advanced technologies like 3D stacking, which combines logic and DRAM chips to enhance performance.
Despite the growing Chinese competition, some relief may come from the U.S. efforts to restrict China’s chip industry, particularly in light of rising geopolitical tensions. Taiwanese chipmakers are beginning to receive orders from international clients asking for chips to be made outside of China, a shift away from previous reliance on Chinese foundries.
