High Manufacturing Costs and Complex Fabrication Processes
The wide bandgap semiconductor market nowadays experiences certain challenges regarding the high production costs and technical complexity of producing SiC and GaN wafers. The fabrication of SiC and GaN wafers is material and equipment intensive, suggesting a higher cost of production than their silicon counterparts.
Yield rates are still on the lower side, and scaling production has turned out to be very difficult. Thus, these factors, combined, impede the further establishment of WBG devices in the market, particularly in cost-sensitive segments and emerging markets.
Expanding Applications in Electric Vehicles and 5G Infrastructure
The rising acceptance of electric vehicles together with the deployment of 5G networks will constitute the main drivers for growth in the WBG semiconductor market. SiC devices realize significant efficiency and thermal stability required by EV powertrains and fast chargers.
GaN, on the other hand, finds application in high-frequency power amplifiers and base stations used in 5G networks. Continued innovation and cost reduction at the manufacturing scale would hasten application in these fast-growing areas.
2020 to 2024 were the years of successive growth by adoption of WBG for Electric Vehicles and Power Electronics. Mass-market penetration was hindered by limited production capabilities and very high prices. So, during these years, SiC advanced ahead of GaN for automotive applications, while GaN is slowly entering niche applications in telecommunication. The benefits of WBG are now in the common knowledge of OEMs, and there is considerable cooperation between semiconductor makers and automotive companies.
From 2025 to 2035, the market will experience an accelerated growth trajectory as WBG devices become commercially viable with increased advances in manufacturing technology and economies of scales. Demand will be driven mainly by the automotive sector, particularly with the increase in electric vehicle (EV) market share and government mandates for emission reductions.
Meanwhile, the 5G infrastructure buildout and renewable energy initiatives will fuel much of the adoption of GaN and SiC devices. Trends in the future will be determined by attempts to enhance wafer quality and reduce defects as well as integrate WBG semiconductors into power modules.
