High k gate dielectric
Web3. Brief history of high-k dielectric development To overcome gate leakage problems and extend the usefulness of SiO2-based dielectric, incorporation of nitrogen into SiO2 has been adopted. There are several ways to introduce nitrogen into SiO2, such as post deposition annealing in nitrogen ambient and forming a nitride/oxide stack structure.

Web10 de abr. de 2011 · Possible high-K materials are SiO2 (k∼3.9)„Al2O3 (K∼10), HfO2/ZrO2 (K∼25) which provide higher physical thickness and reduce the direct tunneling leakage current. So in this paper we study the effect of introduction of wide range of proposed high-k gate dielectrics on the device. WebReplacing the SiO 2 oxide layer with a high- k dielectric layer gives the concept of the electrical thickness, known by the equivalent oxide thickness (EOT) in which the physical thickness (PT) can be increased to improve the device reliability without increasing the effective thickness of the gate dielectric.
