TSMC to open two new advanced chip packaging plants in Taiwan's Chiayi

Taiwan Semiconductor Manufacturing Co (TSMC) plans to build two additional advanced chip packaging plants at the Chiayi Science Park in southern Taiwan, according to Reuters. The second plant is expected to begin mass production soon, expanding what is becoming one of TSMC's most important packaging hubs.
The Chiayi park is projected to generate over $300 billion in annual production value and create more than 9,000 jobs, according to Yahoo Finance. The expansion signals TSMC's push to keep advanced packaging capacity concentrated on home soil.
TSMC is turning the Chiayi Science Park into a major hub for advanced chip packaging. The two new plants will join facilities already being developed there. Advanced packaging is a key step in chipmaking. It stacks and connects chips to boost performance without shrinking the transistors further.
Taiwan's science minister confirmed the expansion plans. The second of the two new plants is on track to enter mass production in the near future, Reuters reported. That ramp-up pace reflects how quickly demand for advanced packaging has grown, driven by AI chips and high-performance computing.
The Chiayi park is not just a chip facility — it is a regional economic engine. Authorities estimate it will produce over $300 billion in annual output once fully operational, according to Yahoo Finance. That figure would make it one of the most productive science parks in Taiwan.
The park is also expected to create more than 9,000 jobs in the region. Southern Taiwan has historically lagged behind the north in high-tech industry. This expansion is part of a broader government effort to spread semiconductor investment across the island.
While TSMC has been building fabs in the United States, Japan, and Germany, advanced packaging remains heavily rooted in Taiwan. Packaging technologies like CoWoS — which connects chips used in Nvidia's AI processors — are central to TSMC's competitive edge. Keeping that work in Taiwan gives the company tighter control over quality and supply.
Demand for CoWoS and similar packaging has surged alongside the AI boom. TSMC has been racing to add capacity to meet orders from customers like Nvidia and Apple, according to Market Screener. The Chiayi expansion is a direct response to that pressure.
The Chiayi buildout fits a larger pattern. Taiwan has been investing heavily to keep the most advanced parts of chipmaking on its own soil. Advanced packaging is increasingly seen as just as important as chip design or fabrication. Whoever controls packaging controls a critical bottleneck in the global chip supply chain.
For Taiwan, the stakes are high. The island's economy is deeply tied to TSMC's success. A park generating $300 billion annually and employing thousands of workers would strengthen that bond further, according to Yahoo Finance.
