Samsung commits $1.5bn to a Vietnam chip-testing plant, with $2.5bn more on the table

Samsung Electronics will invest 39 trillion dong, about $1.5bn, in a semiconductor testing plant in Vietnam. Construction has started in an industrial park 60 kilometres north of Hanoi, with operations planned to begin in November 2027. The facility will be Samsung’s first dedicated chip-testing site in Vietnam and is sized to deliver 153.3 billion gigabits per year of DRAM and 255.6 billion gigabits per year of NAND. Samsung plans to reinvest profits, if any, up to an additional $2.5bn for a potential second facility, subject to project performance. Testing verifies and bins memory dies before packaging, addressing industry-wide capacity constraints driven by AI-grade memory demand. The investment also supports Vietnam’s strategy to attract semiconductor supply-chain investment amid shifting regional decisions.

"Samsung Electronics will invest 39 trillion dong, or about $1.5bn, in a semiconductor testing plant in Vietnam, according to a document seen by Reuters on Wednesday. Construction has already begun in an industrial park 60 kilometres north of Hanoi, with operations scheduled to start in November 2027. The plant will be Samsung's first dedicated chip-testing facility in Vietnam."

"The facility is sized to deliver 153.3 billion gigabits a year of DRAM and a further 255.6 billion gigabits of NAND. Samsung has also indicated it intends to reinvest profits from the project, 'if any,' up to a further $2.5bn for a potential second facility, bringing the total committed and contingent footprint to roughly $4bn. Vietnamese authorities approved the first phase in March; the contingent expansion remains subject to project performance."

"Testing, in chip-industry terms, sits between wafer fabrication and final assembly. It is the step at which every memory die produced upstream is verified, binned by performance and prepared for packaging. Capacity in that part of the chain has been an industry-wide bottleneck through 2025 and 2026 as demand for AI-grade memory has run well ahead of installed test infrastructure. Samsung's Vietnam plant addresses that constraint directly without committing to the higher capital expenditure of a new wafer fab."

"The site selection is also a geopolitical signal. Vietnam has spent the past three years actively soliciting chip-supply-chain investment as part of a broader strategy to position itself as a Southeast Asian semiconductor hub. Samsung is already the largest single foreign investor in Vietnam, with cumulative commitments above $23bn across consumer-electronics manufacturing, R&D and supplier operations. The new plant deepens that footprint at exactly the moment US tariff policy has begun pushing chip-supply-chain decisions away from mainland China."
