Qorvo and SK Siltron CSS sign long-term silicon carbide supply agreement
Qorvo Inc of Greensboro, NC, USA (which provides core technologies and RF solutions for mobile, infrastructure and defense applications) has finalized a multi-year agreement for the supply of silicon carbide (SiC) bare and epitaxial wafers from compound semiconductor wafer maker SK Siltron CSS of Auburn, MI, USA (a subsidiary of South Korea-based SK Siltron, a part of the SK Group).
The agreement should promote domestic semiconductor supply chain resilience and a greater ability to support the rapidly rising demand for silicon carbide solutions, specifically in the automotive market. It is also aimed at providing end-user customers a level of protection and confidence as they adopt Qorvo's Gen 4 SiC FETs.
SiC devices are more efficient at handling high powers and conducting heat than traditional silicon. When used in electric vehicle (EV) system components, this allows more efficient transfer of electricity from the battery to the motor, increasing the driving range of an EV by 5-10%, it is reckoned.
