TSMC to Cut Fab14 Mature-Node Capacity by 15%-20% to Reflect Changing Demand Mix
- The company is expected to reduce Fab14’s 12” mature-node capacity by 15%-20% by 2028.
- The move primarily aims to address structurally weak utilization at legacy nodes while freeing resources to support the expansion of advanced packaging technologies.
- To ensure continuity of supply for customers reliant on mature and mid-range nodes, TSMC is increasingly leveraging overseas fabs and affiliated manufacturing platforms.
TSMC has outlined a strategic realignment of mature-node capacity at its Fab14 facility, reflecting disciplined capital allocation and long-term portfolio optimization. According to Counterpoint Foundry Service’s Monthly Intelligence Report, the company is expected to reduce Fab14’s 12” mature-node capacity by 15%-20% by 2028, primarily addressing structurally weak utilization at legacy nodes while freeing resources to support the expansion of advanced packaging technologies.
Going by Counterpoint’s Foundry Market Supply Tracker data, this capacity adjustment is driven by persistently low UT Rate at 40-90nm nodes, where it has remained at ~80% levels with limited visibility for recovery. In contrast, demand for advanced packaging solutions continues to intensify. As a result, TSMC is prioritizing the reallocation of cleanroom space, equipment and capital toward higher-value manufacturing segments.
However, the company has emphasized that this initiative does not reflect a deterioration in end demand for mature-node semiconductors. Rather, it represents a structural optimization of where such production is best located within TSMC’s global manufacturing ecosystem.
To ensure continuity of supply for customers reliant on mature and mid-range nodes, TSMC is increasingly leveraging overseas fabs and affiliated manufacturing platforms. In Japan, the Kumamoto fab (Fab23) is expected to ramp capacity at 40/45nm and 12/16nm by the end of 2026, supporting automotive and ISP-focused supply chains. In Europe, the Dresden fab (Fab24) is progressing through construction and is expected to begin equipment installation in 2027, with meaningful capacity planned at 22/28nm and 12/16nm toward the end of the decade. Select equipment from Fab14 is expected to be redeployed to these sites, enhancing asset utilization while containing overseas capital expenditure.
In parallel, TSMC affiliate VIS is playing an increasingly important role in absorbing mature-node capacity. VIS has announced plans to acquire 12” tools from TSMC to support its expansion into 130nm~40nm processes at its Singapore manufacturing base, VSMC. This arrangement reinforces a clearer division of labor within the group – TSMC focuses on advanced logic and advanced packaging, while VIS addresses stable, long-cycle mature-node demand with greater capital efficiency.
Based on current visibility, TSMC expects to phase out around 50KWPM of Fab14 capacity by 2028, improving operational flexibility and profitability while maintaining customer supply through diversified manufacturing channels.
This realignment underscores TSMC’s long-standing commitment to capital discipline, supply-chain resilience and global manufacturing diversification, positioning the company to meet evolving technology requirements while sustaining long-term value creation for customers and stakeholders.
