High-dielectric-constant materials

Patent Pending The term high-κ dielectric refers to a material with a high dielectric constant κ (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 Law.
