  • Patent number: 12224337
    Abstract: III-N e-mode high electron mobility transistors (HEMTs) including a dopant diffusion spacer between an impurity-doped III-N material layer and a III-N polarization layer of the HEMT material stack. The spacer may be a substantially undoped III-N material, such as GaN. With the diffusion spacer, P-type impurities within the pGaN are setback from the polarization layer sufficiently to avoid significant levels of P-type impurities from entering the III-N material interface where the 2DEG resides. With the diffusion spacer, clustering of impurities near the 2DEG may be avoided and a III-N e-mode HEMT may achieve higher drive currents.
