Abstract:
1. A method of making a transistor 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 the diamond thin film layer for a gate metal to the first dielectric layer surface; etching the first dielectric layer to the semiconductor substrate; depositing a gate metal on the semiconductor substrate; performing a device isolation process by etching or implanting; and forming a contact window opening in the diamond thin film layer and the first dielectric layer to an ohmic contact; wherein the step of performing a device isolation process by etching or implanting is performed after the step of depositing and defining a gate metal.
