    Abstract: The present disclosure relates to an enhancement mode MISFET device. In some embodiments, the MISFET device has an electron supply layer located on top of a layer of semiconductor material. A multi-dielectric layer, having two or more stacked dielectric materials sharing an interface having negative fixed charges, is disposed above the electron supply layer. A metal gate structure is disposed above the multi-dielectric layer, such that the metal gate structure is separated from the electron supply layer by the multi-dielectric layer. The multi-dielectric layer provides fixed charges at interfaces between the separate dielectric materials, which cause the transistor device to achieve a normally off disposition.

    Abstract: The present disclosure, in some embodiments, relates to a method of forming a transistor device. The method may be performed by forming an anode and a cathode over an electron supply layer disposed on a semiconductor material. A doped III-N semiconductor material is formed over the electron supply layer, and an insulating material is formed over the electron supply layer and the doped III-N semiconductor material. The insulating material continuously extends from over the anode to over the cathode. The insulating material is patterned to form sidewalls of the insulating material that define an opening over the doped III-N semiconductor material. A gate structure is formed directly between the sidewalls of the insulating material and over the doped III-N semiconductor material.
