Infineon’s 200 mm fabs matter because larger silicon-carbide (SiC) wafers can put more power devices through each production cycle and spread fixed manufacturing costs across more output. Villach in Austria and Kulim in Malaysia provide the SiC expansion, while Dresden’s 300 mm Smart Power Fab adds high-volume silicon power and analog/mixed-signal capacity for electric vehicles, renewable energy, grids and AI data centers.
What “200 mm” means in semiconductor manufacturing
The 200 mm label refers to the wafer diameter used during fabrication, not to the size of an individual chip. A larger wafer provides substantially more usable surface area than a 150 mm wafer, so manufacturers can place more dies on each wafer and distribute fixed process costs over a larger batch.
That makes wafer diameter a manufacturing and economics decision. It does not automatically make every chip cheaper: actual economics depend on process yield, equipment utilization, packaging, qualification and demand. Infineon has not published a general die-count, yield or cost-per-wafer multiplier for its specific 200 mm SiC program.

Why the move is important for SiC
SiC power devices are used where high voltage, switching efficiency and thermal performance matter, including EV inverters, fast chargers, trains and renewable-energy converters. Moving SiC production from 150 mm to 200 mm is intended to increase available capacity and improve cost efficiency as these markets expand.
Infineon’s annual report also describes 300 mm thin-wafer power technology as delivering significantly lower costs and capital investment than 200 mm. That comparison concerns a different manufacturing platform; it shows why wafer size is a strategic lever, not that 300 mm silicon and 200 mm SiC are interchangeable.
Where Infineon makes 200 mm SiC chips
| Site | Wafer and technology | Status and role | Applications identified by Infineon |
|---|---|---|---|
| Villach, Austria | 200 mm SiC | First customer products from the advanced 200 mm process were released in February 2025. | High-voltage renewable-energy systems, rail and electric vehicles |
| Kulim, Malaysia | SiC lines being converted from 150 mm to 200 mm | Conversion was reported on track; Module 3 was preparing for high-volume production aligned with demand and designed to use synergies with existing 200 mm infrastructure. | SiC power-device demand, including automotive and renewable-energy programs |
| Dresden, Germany | 300 mm silicon power, analog and mixed-signal technologies | Smart Power Fab opened on 2 July 2026 after a €5 billion investment. Infineon says it doubles Dresden’s capacity in these areas. | AI-data-center power supplies, renewable generation, grids, electric and software-defined vehicles, and industrial systems |
Villach: the first customer-facing 200 mm SiC products
In February 2025, Infineon announced its first customer products made with advanced 200 mm SiC wafer technology at Villach. The initial products were aimed at high-voltage equipment for renewable energy, rail and electric vehicles. This is a product-release milestone, not a disclosure of a complete production-yield or cost profile.
Kulim: converting an established SiC operation
Kulim’s program is a conversion from 150 mm to 200 mm SiC manufacturing rather than a wholly new material strategy. Infineon said the conversion was on track and that its third module was preparing for high-volume production in line with customer demand. The site’s existing 200 mm infrastructure is intended to create operational synergies as the converted lines ramp.
Dresden: a 300 mm complement, not a 200 mm SiC fab
Dresden’s Smart Power Fab is a 300 mm facility for power semiconductors and analog/mixed-signal technologies. It therefore complements the SiC expansion rather than replacing Villach or Kulim’s 200 mm SiC work. The plant opened on 2 July 2026 following a €5 billion investment and is expected to double Dresden’s capacity in its targeted technologies.

How Villach, Kulim and Dresden are connected
The “One Virtual Fab” model
Infineon’s 2025 annual report describes Villach and Dresden as a coordinated “One Virtual Fab.” The sites use the same processes, equipment, automation and digitalization concepts, allowing Infineon to shift production volumes between them when capacity or demand changes. This is an operating model spanning separate factories, not a single physical building.
The company describes comparable compound-semiconductor synergies between Villach and Kulim. Shared methods and infrastructure can shorten scale-up work and make equipment, engineering knowledge and manufacturing data more reusable across locations.
Public disclosures do not provide a site-by-site interchangeability guarantee for every product. Automotive and industrial chips still require product-specific qualification, and the company has not published independent figures for yields or the volume that can be moved between sites.

Electric vehicles and rail
SiC devices can reduce switching losses in high-power conversion stages such as traction inverters and fast chargers. Infineon’s first Villach 200 mm products specifically target electric vehicles and rail, while its broader SiC expansion is backed by long-term automotive agreements described in the company’s 2023 shareholder letter.

Renewable generation and power grids
Solar and wind installations, storage systems and grid equipment all require efficient conversion between electrical voltages and frequencies. Villach’s initial product focus includes renewable-energy equipment, and Dresden’s power devices and intelligent switches are intended for renewable generation and grids.
AI data centers
AI servers increase the amount of power that data centers must deliver, convert and regulate. Infineon says Dresden’s output will include power semiconductors and analog/mixed-signal components for AI-data-center power supplies. The fab does not produce an “AI chip”; it supplies the power-management building blocks that help deliver electricity to computing systems.
Industrial and software-defined vehicles
Dresden’s stated application set also includes industrial systems and software-defined vehicles. Analog and mixed-signal devices measure, control and communicate electrical conditions around the main power stages, so they are produced alongside power technologies in the Smart Power Fab.

Why the network matters for supply resilience
Manufacturing across Austria, Germany and Malaysia gives Infineon more than one location for key compound- and power-semiconductor processes. The One Virtual Fab approach adds flexibility to the physical geographic spread by allowing qualified production volumes to be balanced between Villach and Dresden. Infineon presents the Dresden investment as strengthening European microelectronics supply chains, while Kulim provides additional Asian capacity for SiC.

Geographic diversity does not eliminate risk. A product may still depend on a particular tool, package, raw-material source or customer qualification. The public information establishes the intended flexibility, not guaranteed continuity for every part number.
How large is the investment and commercial opportunity?
- Dresden investment: Infineon says the Smart Power Fab represents €5 billion and created 1,000 direct jobs.
- Wider employment estimate: Infineon cites an experts/ZVEI study estimating a 1:6 ecosystem job effect. That is an attributed estimate, not a measured employment result from the fab.
- SiC revenue outlook: In its 2023 shareholder letter, Infineon projected about €7 billion in annual revenue potential by the end of the decade from its SiC expansion and 200 mm conversions. This is company guidance issued in 2023, not realized revenue.
The same 2023 outlook cited long-term automotive and renewable-energy agreements supporting the expansion. Those agreements indicate planned demand coverage, but they do not reveal future utilization, product margins or the final cost advantage of each wafer size.

It does indicate a scale strategy
Moving SiC from 150 mm toward 200 mm signals that Infineon is preparing for larger production volumes and seeking better cost efficiency. The combination of converted Kulim modules, Villach customer releases and Dresden’s 300 mm expansion points to a coordinated capacity plan rather than a single-fab experiment.
It does not guarantee lower prices or immediate supply
Wafer enlargement alone cannot establish a chip’s selling price, production yield or delivery lead time. Those outcomes depend on ramp execution, qualification, utilization and the specific device design. Infineon has not publicly provided independent production statistics that would support a universal percentage saving or capacity gain.

How to compare Infineon with another power-semiconductor manufacturer
A meaningful comparison should examine the full manufacturing strategy rather than the wafer number alone:
- Wafer diameter: 150 mm, 200 mm or 300 mm
- Material: silicon, SiC or gallium nitride
- Target voltage range and end application
- Owned-fab capacity versus foundry or outsourced supply
- Geographic redundancy and ability to shift qualified production
- Ramp timing and customer-qualification status
- Evidence for cost, scale and capacity claims
Those criteria distinguish a 200 mm SiC expansion from a 300 mm silicon power program, even when both are described as “power semiconductor” investments.
Bottom line
Infineon’s 200 mm fabs matter because they are the manufacturing core of a broader power-semiconductor network. Villach has already released customer products from 200 mm SiC wafers, Kulim is converting additional SiC capacity, and Dresden’s 300 mm Smart Power Fab adds silicon power and analog/mixed-signal output. Together, the sites are designed to support electrification, renewable power, grids and AI infrastructure while giving Infineon more scale and operational flexibility than a single-factory approach.
