The degradation of device. performance induced by program/erase cycling is discussed, specifically for what concern the leakage that affect a very small fraction of memory cells after cycling. The dependence of the leakage on tunnel oxide thickness, number of cycles, and temperature is analyzed. The leakage current is explained by trap-assisted tunneling involving one, two or more traps, with decreasing occurrence probability. Finally, data are presented showing the robustness of scaled Flash memory to alpha particles and electromagnetic radiation.","PeriodicalId":158994,"journal":{"name":"2004 International Conference on Integrated Circuit Design and Technology (IEEE Cat.

Film properties and integration performance of carbon doped oxides 碳掺杂氧化物的薄膜性能及集成性能

{"title":"Film properties and integration performance of carbon doped oxides","authors":"Hichem MSaad","doi":"10.1109/ICICDT.2004.1309922","DOIUrl":"https://doi.org/10.1109/ICICDT.2004.1309922","url":null,"abstract":"Summary form only given. The semiconductor industry has witnessed a successful introduction of copper based interconnects and low permittivity insulators with 130nm node devices. The advent of 90nm node devices has led to the introduction of first generation of carbon doped dielectric films. Further scaling will require materials with lower permittivity and this has accelerated the development of a second generation of carbon doped oxides with imbedded porosity. While the addition of carbon to a silicon based dielectric lowers the permittivity of the insulator, carbon doping may also lead to degradation in the surface properties of such films. Frequently, carbon enrichment at surfaces is known to cause issues with the wetting characteristics of the surface. In addition, the mechanical strength of interfaces formed with carbon enriched surfaces may be poor compared to congruent surfaces. The high number of chemically and morphologically different materials in the integrated interconnects structure increase the possibility of mechanical structural failure. A detailed understanding of the basic material properties and the behavior of the carbon doped materials during subsequent processing is therefore of prime importance. This paper will present an overview of process and film property characterization of different generations of carbon doped oxides. Integration properties of these films and correlation to processing parameters and physical properties of the materials will be discussed. Novel processing techniques are discussed that enable the implementation of advanced low dielectric constant materials without sacrificing the high volume manufacturability of such films.","PeriodicalId":158994,"journal":{"name":"2004 International Conference on Integrated Circuit Design and Technology (IEEE Cat.

The silicon nanocrystal based NOR Flash can be programmed and erased using conventional techniques in floating gate memories. Key aspects of this technology are the ability to form nanocrystals of the right size and density, the ability to protect them from subsequent processing effects and the ability to remove them from undesired areas. The use of isolated silicon nanocrystals for charge storage provides the opportunity to reduce the program and erase voltages due to tunnel oxide scaling and also has potential for two bits/cell operation. Optimization of tunnel and control oxides is critical to obtain high program/erase cycling endurance. Due to the area savings from memory module peripheral voltage scaling and the reduction in mask count over conventional floating gate technology, silicon nanocrystal non-volatile memory technology can substantially reduce the cost of embedded flash at the 90nm technology node and beyond.","PeriodicalId":158994,"journal":{"name":"2004 International Conference on Integrated Circuit Design and Technology (IEEE Cat.
