According to UDN Money and CNA reports, the second phase of Chiayi Science Park held its groundbreaking ceremony on July 12, 2026. The site spans about 90 hectares and is expected to complete overall development by 2031. TSMC will build 3 more advanced packaging plants there, adding to the 2 already set up in Phase 1.
When was the Chiayi Science Park Phase 2 groundbreaking held, and who organized it?
According to UDN Money, the second phase of Chiayi Science Park held its groundbreaking ceremony on July 12, 2026 (E1). The event was organized by the Southern Taiwan Science Park Bureau under the National Science and Technology Council, which held a groundbreaking blessing ceremony on the 12th and formally announced the official launch of the Chiayi Science Park Phase 2 site (E11), as reported by TechNews.
What is the scale and development timeline of Phase 2?
According to UDN Money, the Phase 2 site covers approximately 90 hectares, with overall development expected to be completed by 2031 (E2). The report specifies the same 2031 target as the year for completing full development (E3).
How does TSMC's advanced packaging layout in Phase 2 compare to Phase 1?
According to CNA, TSMC (台積電) set up 2 advanced packaging (先進封裝) plants in Chiayi Science Park Phase 1 (E8). Building on that, TSMC will construct 3 more packaging plants in the Phase 2 site that broke ground on the 12th, aiming to build a global advanced packaging hub (E7).
| Phase | TSMC packaging plants | Source |
|---|
| Phase 1 | 2 advanced packaging plants | CNA (E8) |
| Phase 2 | 3 packaging plants | CNA (E7) |
What industries will move into Phase 2?
According to TechNews, beyond TSMC, firms in biomedicine, aerospace, and precision machinery are expected to move in and build facilities in the park over time (E12).
What is the projected economic impact once both phases are complete?
According to UDN Money, once Chiayi Science Park Phases 1 and 2 are fully completed, they are expected to create over NT$300 billion (3,000億元) in annual output value and more than 9,000 new jobs (E4).
What is the production status of TSMC's Phase 1 facility?
According to UDN Money, Phase 1 has entered substantive operation, with the TSMC facility starting mass production in June 2026 (E5).
What did County Magistrate Weng Chang-liang say about Chiayi's transformation?
According to UDN Money, County Magistrate Weng Chang-liang (翁章梁) said Chiayi is gradually transforming from a traditional agricultural city into a high-tech industrial hub, and will play a more critical role in Taiwan's overall industrial layout (E6). As reported by CNA, he said that in a few years, Chiayi will have shifted from a supplier of agricultural and fishery products into a global hub for high-end chip advanced packaging (E10). According to TechNews, he added that machinery, the low-altitude economy, and the satellite economy are all important foundational industries for the future (E13).
Who attended the groundbreaking ceremony?
According to CNA, the ceremony was hosted by NSTC Minister Wu Cheng-wen, with attendees including County Magistrate Weng Chang-liang, DPP legislators Tsai Yi-yu, Chen Kuan-ting, and Wang Mei-hui, as well as TSMC Facilities Vice President Chuang Tzu-shou, along with public works developers, plant construction contractors and their partners, and local representatives (E9).
What this means
The evidence links a clear progression: TSMC moved from 2 advanced packaging plants in Phase 1 (E8) to a planned 3 more in Phase 2 (E7), while the Phase 1 facility already began mass production in June 2026 (E5). Against the 90-hectare Phase 2 site targeting full development by 2031 (E2, E3), officials project over NT$300 billion in annual output and more than 9,000 jobs across both phases (E4). Magistrate Weng's statements (E6, E10, E13) frame this within Chiayi's described shift from an agricultural supplier to a stated global advanced packaging hub, with biomedicine, aerospace, and precision machinery firms also expected to enter (E12).
