As global decarbonization efforts drive demand for power semiconductors, Infineon Technologies AG has officially opened the first phase of a new fab in Malaysia that will become the world’s largest and most competitive 200-millimeter silicon carbide (SiC) power semiconductor fab. Malaysian Prime Minister YAB Dato’ Seri Anwar Ibrahim and Chief Minister of the state of Kedah YAB Dato’ Seri Haji Muhammad Sanusi Haji Mohd Nor joined Infineon CEO Jochen Hanebeck, to symbolically launch production.
The highly efficient 200-millimeter SiC power fab will strengthen Infineon’s role as the global leader in power semiconductors. The first phase of the fab, with an investment volume of two billion euros, will focus on the production of silicon carbide power semiconductors and will include gallium nitride (GaN) epitaxy. SiC semiconductors have revolutionized high-power applications because they switch electricity even more efficiently and enable even smaller designs.
SiC semiconductors increase efficiency in electric vehicles, fast charging stations and trains as well as renewable energy systems and AI data centers. 900 high-value jobs will be created already in the first phase. The second phase, with an investment of up to five billion euros, will create the world’s largest and most efficient 200-millimeter SiC power fab. Overall, up to 4.000 jobs will be created with the project.
“New generations of power semiconductors based on innovative technology such as silicon carbide are an absolute prerequisite to achieving decarbonization and climate protection. Our technology increases the energy efficiency of ubiquitous applications such as electric cars, solar and wind power systems and AI data centers. We are therefore investing in the largest and most efficient high-tech SiC production facility in Malaysia, backed by strong customer commitments,” said Jochen Hanebeck, CEO of Infineon Technologies AG. “Since the demand for semiconductors will constantly rise, the investment in Kulim is highly attractive to our customers, who are backing it with their prepayments. It also increases the resilience of the supply chain for critical components needed for the green transition.”
“Infineon’s remarkable project reinforces Malaysia’s position as a rising major global semiconductor hub” says Malaysian Prime Minister YAB Dato’ Seri Anwar Ibrahim. “This major investment, which will locate the world’s largest and most competitive SiC power fab on our shores, will create jobs and opportunities, as well as attract suppliers, universities and top talent. Moreover, it will support Malaysia’s efforts to protect our climate by boosting electrification and increasing the efficiency of many applications, including electric cars and renewable energy. Thus, technology made in Malaysia will become a central part of global decarbonization efforts in the future.”
“Infineon’s deeply rooted presence in Kulim is a testament to the region’s potential as a hub for high-tech industries,” says Kedah Chief Minister YAB Muhammad Sanusi Md Nor. “This investment will not only create high-value job opportunities for the local community, it will also catalyze economic growth in the region. We are committed to continue providing top business conditions in Kedah and supporting Infineon’s efforts to establish a leading semiconductor facility in Kulim, which will have a positive ripple effect on the entire ecosystem.”
Infineon has secured design wins with a total value of approximately five billion euros and has received approximately one billion euros in prepayments from existing and new customers for the ongoing expansion of the Kulim 3 fab. Notably, these design wins include six OEMs in the automotive sector as well as customers in the renewable energy and industrial segments.
Kulim 3 will be closely connected to the Infineon site in Villach, Austria, Infineon’s global competence center for power semiconductors. Infineon already increased capacity for SiC and GaN power semiconductors in Villach in 2023. As “One Virtual Fab” for wide-bandgap technologies, both manufacturing sites now share technologies and processes which allow for fast ramping and smooth and highly efficient operation. The project also offers a high grade of resilience and flexibility, which will ultimately benefit Infineon’s customers.
The expansion will benefit from the excellent economies of scale already achieved for 200-millimeter manufacturing in Kulim. It will complement Infineon’s leading position in silicon, based on 300-millimeter manufacturing in Villach and Dresden. Thus, Infineon is strengthening its technological leadership across the entire spectrum of power semiconductors, in silicon as well as SiC and GaN.
In addition, the investment in wide-bandgap capacity in Kulim strengthens the local ecosystem and proves that Infineon is a reliable partner within the growing semiconductor hub Malaysia. Infineon’s operations in Malaysia started as early as 1973 in Melaka. In 2006, the company opened Asia’s first frontend fab in Kulim. Currently, Infineon employs more than 16.000 highly skilled people in Malaysia.
The Kulim 3 fab will be powered by 100% green electricity and will employ the latest energy efficiency measures to support Infineon’s goal of carbon neutrality. To avoid emissions, Infineon will use a state-of-the-art abatement system and green refrigerants that combine high efficiency with extremely low global warming potential. Other measures to ensure sustainable operations include state-of-the-art recycling of indirect materials and state-of-the-art water efficiency and recycling processes. Infineon is working towards recognition with the renowned Green Building Index certification.

Nexperia announced that the ongoing expansion of its NextPower 80 V and 100 V MOSFET portfolio is continuing apace with the release of several new LFPAK devices in industry-standard 5×6 mm and 8×8 mm footprints. These new NextPower 80/100 V MOSFETs are optimized for low (RDSon) and low Qrr, to deliver high efficiency and low spiking in applications including servers, power supplies, fast chargers and USB-PD as well as for a wide range of telecommunications, motor control and other industrial equipment. Designers can choose from a range of 80 V and 100 V devices, with (RDSon) from 1.8 mΩ to 15 mΩ.
Many MOSFET manufacturers focus on achieving high efficiency through low QG(tot) and low QGD, when benchmarking the switching performance of their devices against alternative offerings. However, through extensive research, Nexperia has identified Qrr as being even just as important due to its impact on spiking and, in turn, the amount of electromagnetic interference (EMI) generated during device switching.
By focusing on this parameter, Nexperia has considerably reduced the level of spiking produced by its NextPower 80/100 V MOSFETs and hence also lowered the amount of EMI they produce. This brings significant benefits for end users by reducing the probability of a costly late-stage redesign to include additional external components if their application fails electromagnetic compatibility (EMC) testing.
The on-resistance (RDSon) of these new MOSFETs has been reduced by up to 31% compared to currently available devices. Nexperia also plans to further strengthen its NextPower 80/100 V portfolio later this year with the release of an additional LFPAK88 MOSFET offering RDS(on) down to 1.2 mΩ @ 80 V, as well as introducing the power dense CCPAK1212 to the portfolio. To further support design-in and qualification of these devices, Nexperia offers the availability of award-winning interactive datasheets, providing engineers with comprehensive and user-friendly insights into device behavior.

Toshiba Electronic Devices & Storage Corporation and Toshiba Corporation (Toshiba Group) have developed technology that mitigates the parasitic oscillation that occurs during switching operations by power modules with silicon carbide (SiC) MOSFETs connected in parallel, even with a 60% smaller gate resistance than is typical. The technology reduces power loss in power modules, mitigates oscillation, and realizes highly reliable switching operations.
The drive for carbon neutrality is stimulating demand for technologies that improve energy efficiency in many areas, including renewables, railways, and industrial equipment. In these sectors, the application of power modules built around SiC MOSFETs is seen as a solution that supports high-speed switching at high voltages and large currents—which is particularly important for the miniaturization of power converters, where higher switching frequencies result in higher rates of switching losses against power consumption.
Connecting multiple chips in parallel in power modules can form oscillation circuits, the result of wiring inductance between the chips and their parasitic capacitance. It can reduce module reliability if not countered, which is usually done by increasing gate resistance. However, this approach slows switching speed, resulting in a trade-off with switching losses. For power modules with SiC MOSFETs to perform high-speed switching, another approach is needed.
Toshiba Group used an equivalent circuit model of the power module (Figure 1) to determine the theoretical condition that triggers parasitic oscillation, and developed a wiring layout less likely to cause it. This was done by analyzing simulations of parasitic oscillation occurs when Lg/Ls, the ratio of gate-to-gate inductance Lg and source-to-source inductance Ls of parallel chips, is below a certain value (Figure 2). As increasing Lg/Ls is an effective means of mitigating parasitic oscillation, Toshiba Group fabricated prototype modules with different Lg/Ls and measured switching. This confirmed that increasing Lg/Ls mitigated oscillation, even with a 60% smaller gate resistance than that required by the alternative approach of increasing gate resistance (Figure 3).
Applying this approach to oscillation mitigation in power modules now under development has realized a power module less likely to cause parasitic oscillation, even with minimal gate resistance, that achieves low power loss with mitigated oscillation, and delivers highly reliable switching operation. Toshiba Group will continue to make refine the modules toward an early product launch.
Toshiba Group presented the details of this technology on June 6 at the 36th International Symposium on Power Semiconductor Devices and ICs (ISPSD) 2024, an international power semiconductor conference held in Bremen, Germany from June 2 to 6.
