VIS weighs second Singapore plant as AI demand fills its first fab

Vanguard International Semiconductor (VIS) is planning a second wafer fabrication plant in Singapore. Its first one there just opened, and its capacity is already spoken for.

The move runs through VSMC, the joint venture VIS operates with NXP Semiconductors. The reason is AI demand, specifically for the less glamorous specialty chips that AI infrastructure quietly depends on.

A fab that sold out before it switched on

VSMC inaugurated its first 300mm fab in Tampines on September 28, 2026. Production is expected to begin in Q1 2027.

That gap matters. The initial capacity of the facility has already been fully booked, so customers committed to output that does not exist yet.

VIS Chairman Leuh Fang said customer demand has stretched the first facility’s capacity beyond its limits. That pressure is what prompted the company to start evaluating a second plant.

The economics of the first site are not small. The investment is estimated at approximately US$6.7 billion to US$7.8 billion.

The plan calls for the Tampines fab to reach 44,000 wafers per month by 2029. It is also expected to create about 1,600 jobs.

Who owns what, and what it makes

The joint venture is split 60% to VIS and 40% to NXP. That structure gives VIS the controlling stake and NXP a guaranteed seat at the capacity table.

VSMC focuses on manufacturing processes between 40nm and 130nm. These are mature nodes, meaning older and larger chip geometries rather than the bleeding-edge processes used for flagship AI accelerators.

NXP CEO Rafael Sotomayor has framed the facility around a specific idea. He said it will significantly contribute to enabling “physical AI” across sectors including automotive and industrial applications.

“Physical AI” across automotive and industrial applications is the opportunity NXP’s Rafael Sotomayor has tied to the facility.

Physical AI refers to intelligence that lives in machines interacting with the real world, rather than in a chatbot window. Cars, factory equipment, and industrial systems all fall into that bucket.

What this means for the chip supply chain

The most immediate signal is about capacity tightness. If the first VSMC fab is fully booked before production starts in Q1 2027, buyers of mature-node chips may face a more competitive environment for supply.

For VIS and NXP, the second plant is still at the evaluation stage. No timeline, investment figure, or capacity target for it appears in the details shared so far, so it should be treated as a plan rather than a commitment.

The first fab’s numbers offer a sense of scale, though. A facility costing approximately US$6.7 billion to US$7.8 billion, ramping to 44,000 wafers per month by 2029, is a long-horizon bet that a second site would presumably have to match or justify.

There are risks worth tracking. The first fab still has to execute its ramp, hitting its Q1 2027 production start and scaling toward its 2029 target on schedule.

Singapore, meanwhile, stands to benefit from the jobs and investment tied to the first site. A second plant would deepen that footprint, though the details of any such facility have yet to be laid out.

The key things to watch are straightforward. Look for a formal decision on the second plant, any updated investment figures, and whether the Tampines fab starts production on its expected Q1 2027 schedule.
