High k dielectric ald
WebLow power consumption is of critical importance for organic field effect transistors (OFETs) in next-generation flexible and wearable electronics, wherein the use of high-k dielectric … 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 …
