5N Plus Inc. announced that it is officially launching the commercialization rights for its portfolio of gallium nitride on silicon (GaN-on-Si) patents that will take semiconductors and power switching technology to the next level. These key patents can enable the rapid prototype development and first-to-market commercialization of novel vertical GaN-on-Si power devices by companies operating in the High-Power Electronics (HPE), Electric Vehicles (EV) and Artificial Intelligence (AI) server sectors. A mechanically stable, wide-bandgap semiconductor material with high heat capacity and thermal conductivity, GaN has outstanding properties.

Today, lateral GaN is primarily used in low voltage (<400V) applications, such as chargers, but novel vertical GaN- on-Si has the potential to replace silicon carbide (SiC), which is the current preferred material for medium and high voltage applications (i.e. EV inverters operating 650V). SiC is expensive and not easily available, whereas GaN-on-Si is more efficient and cost-effective. Recent academic demonstrations utilizing key 5N+ patents have shown that vertical GaN-on- Si, as opposed to lateral GaN transistors showing destructive breakdown, offers soft breakdown with avalanche capability for safe, compact and more efficient devices.

Also included in this patent is the ability to remove the substrate to form the backside contacts once the GaN growth is complete. In addition, the Company holds lateral GaN-on-Si patents for radiofrequency (RF) applications that will enable next generation 5G and 6G wireless communication components. 5N+ holds these patents through its wholly owned subsidiary AZUR SPACE Solar Power GmbH, a leader in multi-junction solar cell technology.
