TSMC helped create a DRAM company — VIS became a speciality foundry instead
Vanguard International Semiconductor was established in Taiwan in 1994 with backing that included TSMC and Taiwan’s Industrial Technology Research Institute.
The original business entered DRAM production before market conditions pushed the company towards a foundry model.
Vanguard International Semiconductor’s present-day business makes more sense when viewed through those early choices. The company repeatedly reused existing expertise rather than reinventing itself from nothing.
Memory exposed VIS to the commodity cycle
DRAM manufacturing required large capital investment while prices moved sharply with supply and demand.
In semiconductor and electronics markets, this kind of capability compounds over time. Manufacturing know-how, yields, supplier relationships and process experience are difficult to recreate quickly, so each generation can strengthen the next.
Speciality foundry work offered a more differentiated path
VIS shifted away from commodity memory and focused on manufacturing analogue, power, display-driver and mixed-signal chips for external customers.

Older process nodes became an advantage, not a weakness
Many power and analogue products value reliability, voltage handling and cost more than the smallest transistor dimensions.
This was an important turning point because it expanded what Vanguard International Semiconductor could offer or the markets it could address. The effect becomes clearer when viewed as part of the longer sequence of changes that followed.
Acquisitions expanded capacity outside the original fabs
VIS added manufacturing assets, including a Singapore fab, to broaden geographic and process capabilities.

A new Singapore joint venture moved VIS to larger wafers
The company partnered with NXP on a new 300mm manufacturing project, extending the speciality-foundry strategy into larger-diameter production.

The memory company that found stability by leaving memory
As of 18 September 2026, vIS now operates as a speciality semiconductor foundry focused on mature and analogue-oriented processes.
The company’s current position is therefore the result of accumulated technical and commercial choices rather than one breakthrough product. That is the context future coverage should preserve.
