Gate oxide thickness high temperature anneal
WebJan 16, 2024 · High-K gate dielectric HfAlO thin films with different temperature annealing treatment have been deposited on the Si substrate by atomic layer deposition. The electrical properties of Hf-films are analysed by measurement of high-frequency capacitance–voltage (C–V) and leakage current density–voltage (J–V) characteristics. The electrical … WebWhen the annealing temperature is increased to 600 °C, the content of both tends to be in the equilibrium state. In the case of the dielectrics, the doping amount of Dy in the film is slightly increased as the annealing …

WebMay 9, 1999 · The antenna dependence of residual degradation is observed in the device threshold voltage, transconductance, and sub-threshold behaviour. The residual damage is observed due to incomplete annealing of oxide charge and interface states, and its level depends on the intensity of plasma charging stress and on the gate oxide thickness. WebOct 15, 2009 · As we know, the DPN is a low temperature process. In order to achieve good gate oxide integrity, the post-DPN annealing under high temperature is introduced to improve the Si–SiO 2 interface property and reduce trap density in the gate oxide [7]. In this paper, the effect of post-nitridation annealing on DPN ultra-thin gate oxide was ...
WebJul 1, 2003 · The high-temperature annealing in hydrogen ambient was followed to form rounded trench corners. A 50 nm of thermal screen SiO 2 was grown and removed to improve the surface of the trench. Then, 50 nm of gate oxide was thermally grown and followed trench filling using a doped polysilicon for a gate of the device. WebIn general, reduction of the thickness of gate oxide is a pivotal factor in CMOS scaling. However, reduction of the thickness results in the exponen-tial increase in leakage current. To overcome this problem, high-K dielectric constant material is re-quired to replace the conventional SiO 2 [1]. Among the candidates predicted to be thermody-
Webleakage current density. The high annealing temperature could make films to produce crystals, which is a pathway to deliver the leakage current. Due to the interfacial layer between HfAlO films after annealing and substrate has more interface states, which have bad influence on the leakage current.
