SiC (Silicon Carbide) is expected to be widely used in inverters and other automotive power devices in 2025. Leading international manufacturers such as Wolfspeed and Coherent have launched mass production of 8-inch SiC wafers, thereby boosting SiC wafer production capacity. Hence, reducing production costs has become the focus of interest in the industry. This report looks into the 8-inch SiC wafer mass production plans and production progress of leading manufacturers, discusses solutions aimed to increase production capacity and reduce production costs, and analyzes the impact of global manufacturers’ efforts to mass produce 8-inch SiC wafers on the industry.

Primary research with a holistic, cross-domain approach

The exhaustive primary research methods are central to the value that the analyst delivers. A combination of questionnaires and on-site visits to the major manufacturers provides a first view of the latest data and trends. Information is subsequently validated by interviews with the manufacturers' suppliers and customers, covering a holistic industry value chain. This process is backed up by a cross-domain team-based approach, creating an interlaced network across numerous interrelated components and system-level devices to ensure statistical integrity and provide in-depth insight.

Complementing primary research is a running database and secondary research of industry and market information. Dedicated research into the macro-environmental trends shaping the ICT industry also allows the analyst to forecast future development trends and generate foresight perspectives. With more than 20 years of experience and endeavors in research, the methods and methodologies include:


  • Component supplier interviews
  • System supplier interviews
  • User interviews
  • Channel interviews
  • IPO interviews
  • Focus groups
  • Consumer surveys
  • Production databases
  • Financial data
  • Custom databases


  • Technology forecasting and assessment
  • Product assessment and selection
  • Product life cycles
  • Added value analysis
  • Market trends
  • Scenario analysis
  • Competitor analysis
