Available in PDF, EPUB and Kindle. Book excerpt: This issue covers papers relating to advanced semiconductor products that are true representatives of nanoelectics and that have reached below 100nm. Depending on the application, the nanosystem may consist of one or more of the following types of functional components: electronic, optical, magnetic, mechanical, biological, chemical, energy source, and various types of sensing devices. As long as one or more of these fuctional devices is in the 1-100nm dimensions, the resultant system can be defined as a nanosystem. Papers will be in all areas of dielectric issues in nanosystems. In addtional to traditional areas of semiconductor processing and packaging of nanoelectronics, emphasis will be placed on areas where multifunctional device integration (through innovation in design, materials, and processing at the device and system levels) will lead to new applications of nanosystems.
Download or read book Hafnium doped Tantalum Oxide High k Gate Dielectric Films for Future CMOS Technology written by Jiang Lu and published by . This book was released on 2007 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: A novel high-k gate dielectric material, i.e., hafnium-doped tantalum oxide (Hf-dopedTaOx), has been studied for the application of the future generation metal-oxide semiconductor field effect transistor (MOSFET). The film's electrical, chemical, and structural properties were investigated experimentally. The incorporation of Hf into TaOx impacted the electrical properties. The doping process improved the effective dielectric constant, reduced the fixed charge density, and increased the dielectric strength. The leakage current density also decreased with the Hf doping concentration. MOS capacitors with sub-2.0 nm equivalent oxide thickness (EOT) have been achieved with the lightly Hf-doped TaOx. The low leakage currents and high dielectric constants of the doped films were explained by their compositions and bond structures. The Hf-doped TaOx film is a potential high-k gate dielectric for future MOS transistors. A 5 Å tantalum nitride (TaNx) interface layer has been inserted between the Hf-doped TaOx films and the Si substrate to engineer the high-k/Si interface layer formation and properties. The electrical characterization result shows that the insertion of a 5 Å TaNx between the doped TaOx films and the Si substrate decreased the film's leakage current density and improved the effective dielectric constant (keffective) value. The improvement of these dielectric properties can be attributed to the formation of the TaOxNy interfacial layer after high temperature O2 annealing. The main drawback of the TaNx interface layer is the high interface density of states and hysteresis, which needs to be decreased. Advanced metal nitride gate electrodes, e.g., tantalum nitride, molybdenum nitride, and tungsten nitride, were investigated as the gate electrodes for atomic layer deposition (ALD) HfO2 high-k dielectric material. Their physical and electrical properties were affected by the post metallization annealing (PMA) treatment conditions. Work functions of these three gate electrodes are suitable for NMOS applications after 800°C PMA. Metal nitrides can be used as the gate electrode materials for the HfO2 high-k film. The novel high-k gate stack structures studied in this study are promising candidates to replace the traditional poly-Si-SiO2 gate stack structure for the future CMOS technology node.

Download or read book Gate Dielectrics and MOS ULSIs written by Takashi Hori and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 362 pages. Available in PDF, EPUB and Kindle. Book excerpt: Gate Dielectrics and MOS ULSIs provides necessary and sufficient information for those who wish to know well and go beyond the conventional SiO2 gate dielectric. The topics particularly focus on dielectric films satisfying the superior quality needed for gate dielectrics even in large-scale integration. And since the quality requirements are rather different between device applications, they are selected in an applicatipn-oriented manner, e.g., conventional SiO2 used in CMOS logic circuits, nitrided oxides, which recently became indispensable for flash memories, and composite ONO and ferroelectric films for passive capacitors used in DRAM applications. The book also covers issues common to all gate dielectrics, such as MOSFET physics, evaluation, scaling, and device application/integration for successful development. The information is as up to date as possible, especially for nanometer-range ultrathin gate-dielectric films indispensible in submicrometer ULSIs. The text together with abundant illustrations will take even the inexperienced reader up to the present high state of the art. It is the first book presenting nitrided gate oxides in detail.

Download or read book Hf Based High k Dielectrics written by Young-Hee Kim and published by Morgan & Claypool Publishers. This book was released on 2006-01-01 with total page 100 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this work, the reliability of HfO2 (hafnium oxide) with poly gate and dual metal gate electrode (Ru–Ta alloy, Ru) was investigated. Hard breakdown and soft breakdown, particularly the Weibull slopes, were studied under constant voltage stress. Dynamic stressing has also been used. It was found that the combination of trapping and detrapping contributed to the enhancement of the projected lifetime. The results from the polarity dependence studies showed that the substrate injection exhibited a shorter projected lifetime and worse soft breakdown behavior, compared to the gate injection. The origin of soft breakdown (first breakdown) was studied and the results suggested that the soft breakdown may be due to one layer breakdown in the bilayer structure (HfO2/SiO2: 4 nm/4 nm). Low Weibull slope was in part attributed to the lower barrier height of HfO2 at the interface layer. Interface layer optimization was conducted in terms of mobility, swing, and short channel effect using deep submicron MOSFET devices.
