Business Strategies - SiC Epitaxial Wafers
Relationship Between Our Products and Daily Life
SiC epitaxial wafers are mainly used as substrates for power semiconductor devices and contribute to energy conservation in various fields, such as renewable energy and electric vehicles (EVs).
Mission of SiC Epitaxial Wafers Business
As the world’s largest independent supplier and technology leader of SiC epitaxial wafers, key materials for improving the performance of the growing SiC power semiconductors, we will strive to provide solutions while co-creating with customers to help realize energy conservation around the world.
Initiatives to Strengthen Competitiveness and Examples
We will make use of Resonac’s strengths and competitive advantages to become a world-class functional chemical company and a company that can compete on the world stage by 2030.
Strengths as a Manufacturer Specialized in Epitaxial Wafers
As a manufacturer specialized in epitaxial wafers that does not handle SiC devices, we attract device manufacturers that manufacture wafers and epitaxial wafers in-house as customers. This unique business model allows us to improve quality and accumulate expertise by gathering the needs of multiple customers and aligning specifications. In 2022, we began test shipments of eight-inch (200 mm) SiC epitaxial wafers, which contribute significantly to larger wafer diameters while enabling us to achieve industry-leading quality by fully utilizing technology that reduces defects.
Utilization of IP Landscape in SiC Epitaxial Wafers Businesses and Evaluation of Intellectual Property Value
The value of our patents (PAI = Patent Asset Index*: registered trademark of Lexis Nexis) in the field of SiC epitaxial wafers, acquired as a result of our pioneering technological developments, more than doubled that of industry peers in 2024, demonstrating our competitive advantage. Furthermore, France-based KnowMade, which specializes in the analysis of patents and scientific information, highly rated our IP position in the development of larger diameter, low-defect SiC epitaxial wafers.
