Resumen
Fabrication of mosfet transistor gate structures on iii-v semiconductors. This invention proposes to apply the high-pressure spraying of scandium metal nanosheets and a lanthanide and its subsequent oxidation by room temperature plasma on semiconductor substrates iii-v, of interest for mosfet devices, both planar and finfets. The advantage of these semiconductors is that they have greater carrier mobility in the channel than the si, greater transconductance and lower switching delay with respect to current technology. Functional mos structures are obtained on semiconductor alternatives to the si with an optimal step coating. Only high-medium vacuum technologies are required and they have a lower environmental impact than their alternatives. It implies a simplification of the manufacturing process, since no filtering-cleaning process has to be carried out to clean up very harmful waste for the environment and to reduce the vacuum times prior to depositing.
