Infineon Technologies has expended its supplier base for 150mm silicon carbide wafers with a multi-year supply deal with US supplier II-VI that includes the development of 200mm wafers.
The agreement also supports Infineon’s multi-sourcing strategy and increases its supply chain resilience for key SiC material. The first deliveries have already taken place.
As strategic partners, II-VI and Infineon are also collaborating in the transition to 200mm SiC diameter wafers for higher volume production and lower cost SIC devices. II-VI is expanding tis 150mm wafer line in China and developing 200mm capability there.
Infineon says the CoolSiC devices are already the industry’s largest portfolio for industrial power semiconductor applications. In addition to photovoltaic converters and industrial power supplies, the advantages of SiC are also particularly important for e-mobility. SiC power semiconductors are used in the main inverters for e-vehicle drive trains, in onboard battery charging units and in charging infrastructures.
The company has supply agreements with onsemi and Cree in the US and Showa Denko in Japan.

Infineon expects its SiC semiconductor sales to grow by more than 60 percent on average per year, reaching approximately $1 billion by mid-decade. For the second half of the decade, Infineon expects on-going growth momentum, for which it invests in its recently announced additional manufacturing block in Kulim, Malaysia.
