GTAT to supply silicon carbide boules to Infineon

GT Advanced Technologies (GTAT) of Hudson, NH, USA has signed a contract (with an initial term of five years) to supply silicon carbide (SiC) boules to Infineon Technologies AG of Munich, Germany, which is therefore adding a further element to secure its growing base material demand in this area.

Under the name CoolSiC, Infineon already markets what it claims is the industry’s largest product portfolio for industrial applications and is rapidly expanding its offering towards consumer and automotive products.

“We are seeing a steadily increasing demand for SiC-based switches, especially for industrial applications. However, it has become clear that the automotive sector is quickly following suit,” says Peter Wawer, president of Infineon’s Industrial Power Control Division. “With the supply agreement we have now concluded, we ensure that we will be able to meet the rapidly growing demand of our customers with a diversified supplier base. GTAT’s high-quality boules will provide an additional source for competitive SiC wafers fulfilling the best-in-class material standards now and in the future. This supports our ambitious SiC growth plans, making good use of our existing in-house technologies and core competencies in thin-wafer manufacturing,” he adds.

“GTAT will enable Infineon to achieve a secure, high-quality internal SiC wafer supply by applying their proprietary thin-wafer technology to GTAT’s crystal,” says GTAT’s president & CEO Greg Knight. “The growth of SiC device adoption is tied largely to the aggressive cost down of the substrate, and this agreement is a significant step towards achieving that goal.”

SiC has mainly been used up to now in photovoltaic inverters, industrial power supplies, and the charging infrastructure for electric vehicles. This is where the advantages of SiC at the system level, compared with classical silicon solutions, have already come into play. Other industrial applications such as uninterruptible power supplies (UPS) and variable-speed drives are increasingly making use of silicon carbide technology. In addition, electric vehicles show enormous potential for application options, including the main inverters for the drive train and onboard battery charging units.
