II‐VI Incorporated has closed a multi-year contract to supply Infineon Technologies with 150mm silicon carbide (SiC) substrates for power electronics.

The skyrocketing growth of the electric vehicle (EV) market is driving demand for SiC-based power electronics in EV drivetrains, onboard battery charging units, and charging infrastructure.

SiC enables power electronics to be smaller and more efficient, with a lower total system-level cost of ownership than state-of-the-art silicon-based devices.

II-VI announced in March 2022 that it is accelerating its investment in 150mm and 200mm SiC substrate manufacturing with a large-scale factory expansion at its nearly 300,000 square foot factory in Easton, Pennsylvania. With this expansion, II-VI will reach the equivalent of 1 million 150mm substrates annually by 2027, with the proportion of 200 mm substrates growing over time.

With this contract, Infineon is taking the strategic step to secure its supply of 150 mm SiC substrates. II-VI and Infineon will also collaborate in the transition to 200mm SiC substrates.

'SiC compound semiconductors set new standards in power density and efficiency. We are leveraging them to deliver on our strategy of decarbonisation and digitalisation,' said Angelique van der Burg, chief procurement ffficer at Infineon. 'Infineon is increasing investments in its SiC manufacturing capacity to meet the rapidly growing demand from our customers. We are pleased to add II-VI to our strategic supplier base and grow our business together.'
