High k first
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 are usually used to replace a silicon dioxide gate dielectric or another dielectric layer of a device. The implementation of high-κ gate dielectrics is one of several strategies developed to allow further miniaturization of microelectronic components, colloquially referred to as extending Moore's … Web31 de dez. de 2011 · High permittivity ( k) gate dielectric films are widely studied to substitute SiO 2 as gate oxides to suppress the unacceptable gate leakage current when the traditional SiO 2 gate oxide becomes ultrathin. For high- k gate oxides, several material properties are [...] Read more.
