Vietnam’s first wafer fabrication plant is unlikely to hit its 2027 trial production target, according to sources cited by Reuters, with project execution and equipment procurement both behind schedule. Developer Viettel insists the project remains on track.
The sticking point is lithography. A deal to buy ASML equipment has not been signed, and without committed tools there is no route to a working line.
A national ambition running into physics
Vietnam has spent years building a semiconductor story that is mostly back end. Intel runs one of its largest assembly and test sites near Ho Chi Minh City, and a growing cluster of packaging and design work has followed. A wafer fab is a different order of undertaking – far more capital, more water and power, and a supply chain of gases, chemicals and spare parts the country does not yet have.
The plant has been framed as an entry point rather than a leading-edge play, aimed at mature-node parts for automotive, industrial and consumer customers. Even that tier needs a lithography toolset and a qualified process, and the queue for mature tools has lengthened as Chinese foundries absorb available capacity.
Why the slippage matters regionally
Southeast Asia has become the favoured hedge for companies moving assembly out of China without moving it to Taiwan. Malaysia, Singapore and Vietnam have all taken slices of that shift. A delayed Vietnamese fab does not stop the packaging boom, but it keeps the country on the wrong side of the margin line – earning assembly fees rather than wafer revenue.
Viettel’s public position is that nothing has changed. The missing tool deal is the fact that will decide it.
