Web11 de ago. de 2024 · “The high-K dielectric also ensures that lower-voltage operation is possible for such transistors. We estimate that with these 2D materials, the shortest transistors would be about ten times smaller than what is possible with silicon, even with silicon and high-K.” WebHigh k gate dielectrics are required for the sub-65 nm MOS structure because the conventional SiO2 film is too thin (e.g. 2 nm) to minimize the tunneling current and the out diffusion of boron from the gate. A thick layer can be used with the high k material to lower the parasitic capacitance.
