Semiconductor device with improved junction termination extension region
A recently granted patent (Publication Number: US11901407B2) discloses a semiconductor device featuring a unique junction termination extension (JTE) region designed to enhance performance. The device includes an active area extending in a first direction, surrounded by the JTE region comprising multiple field relief sub-regions with field relief elements of different charge types. These elements are strategically spaced apart in a circumferential direction around the active area, contributing to improved functionality and efficiency. Additionally, the device incorporates backside and frontside metal layers, with the active area positioned between them, further optimizing its operational capabilities.
Furthermore, the semiconductor device's innovative design includes varying dopant concentrations and spacings within the JTE region, enhancing its overall performance. The field relief elements and rings within the JTE region extend from the first surface towards the second surface, with specific arrangements and patterns ensuring optimal functionality. The patent also details the use of different charge types, such as p-type and n-type doping, to achieve desired electrical properties within the device. Overall, the semiconductor device's advanced features and configurations aim to push the boundaries of semiconductor technology, offering potential applications in various fields such as silicon, silicon carbide, gallium nitride, and gallium arsenide technologies.
