Web18 mar 2024 · Unfortunately, materials with high dielectric constant usually exhibit weak dielectric strength; the breakdown field is low and/or their leakage current is large in high electric field (5, 9–11).When an external electric field is applied to a high-k dielectric layer, a large Lorentz local field, given by E loc = (k + 2 3) E ext, is applied to high-k materials. Silicon dioxide (SiO2) has been used as a gate oxide material for decades. As metal–oxide–semiconductor field-effect transistors (MOSFETs) have decreased in size, the thickness of the silicon dioxide gate dielectric has steadily decreased to increase the gate capacitance (per unit area) and thereby drive current … Visualizza altro The term high-κ dielectric refers to a material with a high dielectric constant (κ, kappa), as compared to silicon dioxide. High-κ dielectrics are used in semiconductor manufacturing processes where they … Visualizza altro Industry has employed oxynitride gate dielectrics since the 1990s, wherein a conventionally formed silicon oxide dielectric is infused with a small amount of nitrogen.
