ABSTRACT:
A gate after diamond transistor and method of making comprising the steps of depositing a first dielectric layer on a semiconductor substrate, depositing a diamond particle nucleation layer on the first dielectric layer, growing a diamond thin film layer on the first dielectric layer, defining an opening for the gate in the diamond thin film layer, patterning of the diamond thin film layer for a gate metal to first dielectric layer surface, etching the first dielectric layer, depositing and defining a gate metal, and forming a contact window opening in the diamond thin film layer and the first dielectric layer to the ohmic contact.
