Longtan residents change stance, paving way for TSMC's 1.4nm factory

A significant shift in local sentiment has paved the way for Taiwan Semiconductor Manufacturing Company (TSMC) to potentially establish its advanced 1.4nm and other factories at the Longtan Science Park. The expansion, known as Longke Phase III, was previously stalled due to strong local opposition but has now been revived, with TSMC expressing interest in setting up five advanced facilities, including 1.4nm chip plants and advanced packaging facilities.

TSMC is expected to set up five factories, including 1.4nm and advanced packaging plants.

The project initially planned to acquire 158.59 hectares, with 88% being private land, which sparked fierce resistance from residents who formed a self-help group and protested multiple times. This led TSMC to officially withdraw its plant construction plan in Longtan in October 2023. Subsequently, TSMC explored other locations in Tainan, Kaohsiung, and Chiayi, leading to economic benefits in those areas.

TSMC announced its withdrawal from the Longtan plant construction plan.

However, a change in perspective among Longtan residents, who realized the economic opportunities lost, prompted renewed discussions and negotiations. The Science Park Administration and Taoyuan City Government engaged in extensive communication with residents, adjusting the expansion plan. The revised plan now covers 104.19 hectares, allocating approximately 46 hectares for industrial use. The National Science and Technology Council approved the Longke Phase III plan in May, with the Executive Yuan receiving it in June. The goal is to complete land acquisition by the end of 2029 and commence public infrastructure development in 2030, making the land available for companies to establish factories.

TSMC has expressed its willingness to set up facilities if the Longke Phase III procedures are approved.

Industry sources indicate TSMC plans to build two to three 1.4nm factories and two advanced packaging plants at the site, though the final plan is still under consideration. The revival of the Longtan Science Park expansion signifies a crucial development for Taiwan's semiconductor industry, balancing industrial needs with local community concerns.
