Restraints

• Overcoming Integration Barriers in the Adoption of Wide Bandgap Semiconductors

Wide bandgap semiconductors, such as SiC and GaN, require specialized infrastructure, custom design changes, and modifications to both hardware and software to ensure compatibility with legacy systems. This is a considerable barrier, particularly in industries with large installations of silicon-based devices, as it demands expensive retrofits or complete redesigns of existing equipment. These adaptations not only lead to increased costs but can also cause delays in the implementation of new wide bandgap technologies. The need for high precision in the manufacturing and integration processes adds another layer of complexity, as even minor inconsistencies can affect the overall system performance. Furthermore, for sectors like automotive, aerospace, and power generation, where reliability and safety are paramount, the integration process becomes even more rigorous due to the need for compliance with strict regulatory standards. In these cases, the costs associated with ensuring the proper integration of wide bandgap materials into the existing system architecture can be prohibitive, deterring many potential adopters from transitioning to these advanced technologies. Additionally, the learning curve for engineers and technicians when working with new materials and technologies further complicates the transition, slowing down the adoption rate across industries.
