en.Wedoany.com Reported - Samsung Electronics of South Korea plans to advance the production start of the first wafer fabrication plant in the Yongin Semiconductor National Industrial Park to 2029, one to two years earlier than the previously discussed 2030 to 2031 timeframe. Industry sources indicate that Samsung Electronics intends to build six semiconductor manufacturing plants in the park and is currently adjusting construction schedules with the goal of starting operations at the first plant in 2029. However, the company has not yet officially released a revised complete project timeline.
Working backward from this target, site preparation work for the Yongin park must begin by the second half of 2026 at the latest, and the main construction of the first wafer fabrication plant must start within 2027. Advanced semiconductor plants typically require about two years from main construction, cleanroom building, to production equipment installation and production line commissioning. Therefore, accelerating the timeline involves not only shortening the plant construction period but also compressing multiple preliminary stages such as land and above-ground property compensation, land expropriation rulings, contractor selection, infrastructure connections, and equipment installation. Any delay in any of these stages could affect the 2029 production target.
Before the wafer fabrication plant can begin production, it must also complete cleanroom environmental control, ultra-pure water supply, stable power connection, specialty gas delivery, chemical systems, and wastewater treatment facility commissioning. Samsung Electronics of South Korea has not yet disclosed the process node, wafer size, product type, monthly wafer capacity, or the initial equipment list for the first Yongin plant.
Power and water supply are the most critical external conditions in the schedule adjustment. The South Korean government is pushing to accelerate the construction of liquefied natural gas power generation facilities with a total capacity of approximately 3GW, while also studying ways to compress the construction timelines for second and third-phase power supply projects and phased water supply facilities. Lithography, etching, thin-film deposition, ion implantation, cleaning, and inspection equipment in semiconductor production lines require continuous operation; voltage fluctuations or power interruptions can directly affect the wafer batches being processed. Cleaning, wet processes, and facility systems also require a continuous supply of large amounts of high-purity water. Therefore, completing the main plant ahead of schedule does not mean the production line can start immediately; power, industrial water, and facility systems must be operational before equipment commissioning.
The Yongin Semiconductor National Industrial Park is located south of Seoul and is planned as Samsung Electronics' next-generation semiconductor manufacturing base. This adjustment involves the first plant planned by Samsung Electronics and should not be confused with another semiconductor cluster project in the Yongin area being pursued by SK Hynix.
With the construction timeline advanced, the sequencing of the main plant, cleanroom electromechanical systems, and wafer manufacturing equipment also needs to be rearranged. Large wafer fabs typically require cleanroom finishing, power equipment installation, and production equipment move-in to proceed in phases before construction is fully completed, followed by individual machine testing, system integration, trial production, and yield verification. Current public reports only confirm the target production start date of 2029, without specifying whether it will mark factory completion, trial production initiation, or stable mass production. Some media outlets use different terms such as "production start," "operation," and "mass production," and the specific milestone will need to be clarified based on Samsung Electronics' subsequent project plans.
In its investment plan announced last month, Samsung Electronics of South Korea plans to invest approximately 2,030 trillion won in the Pyeongtaek and Yongin semiconductor clusters and build two new chip factories in Gwangju, South Korea. The most clear change for the Yongin project is that the production start target for the first of the six planned plants has been adjusted to 2029; the construction sequence, equipment configuration, and production start timelines for the subsequent five plants have not yet been disclosed.
