These materials offer superior performance over traditional silicon, enabling higher efficiency, power density, and thermal stability in applications such as electric vehicles, renewable energy, and advanced industrial systems. However, the transition from research to high-volume manufacturing is fraught with technical and economic hurdles.

• Material Quality and Defect Density: The production of high-purity, low-defect SiC and GaN substrates remains a significant challenge. Defects such as micropipes, dislocations, and stacking faults can severely impact device yield and reliability. Despite advances in bulk crystal growth and epitaxy, achieving consistent wafer quality at scale is a persistent risk for manufacturers (Cree | Wolfspeed).
• Manufacturing Complexity and Cost: WBG device fabrication requires specialized equipment and process flows distinct from conventional silicon CMOS lines. For example, SiC wafering and polishing are more difficult due to the material’s hardness, while GaN-on-silicon integration faces lattice mismatch and thermal expansion issues. These factors contribute to higher capital expenditures and operational costs, which can limit adoption in cost-sensitive markets (STMicroelectronics).
• Supply Chain Constraints: The supply of high-quality SiC and GaN wafers is limited, with a small number of vertically integrated suppliers dominating the market. This concentration increases vulnerability to supply disruptions and price volatility, especially as demand surges from the automotive and energy sectors (Yole Group).
• Intellectual Property and Standardization: The WBG sector is characterized by intense patent activity and proprietary process technologies. Navigating the IP landscape is a strategic risk, as infringement disputes can delay product launches or result in costly settlements. Additionally, the lack of standardized device architectures and testing protocols complicates qualification and interoperability (Semiconductor Industry Association).
