Abstract: Methods are provided for growing basal plane dislocation (BPD)-free SiC device-ready epilayers, particularly suitable for 4H-SiC devices. The devices are formed via a substantially 100% conversion of BPDs to threading edge dislocations (TEDs) while pinning the conversion point below the epilayer interface. Methods include the formation of a recombination layer on a previously formed and etched buffer layer. Devices allow for improved reliability and efficiency of high voltage switches used in the day-to-day applications such as inverters, uninterrupted power supplies, and other high power handling devices employed in hybrid electric vehicles, aircraft electronic systems, etc. by enabling the manufacture of smaller, lighter, and more efficient, high power SiC devices in a cost effective, reliable platform.
