This book was released on 2011 with total page 148 pages. Available in PDF, EPUB and Kindle. Book excerpt: The future of mixed-signal, memory, and microprocessor technologies are dependent on ever increasing analog and digital integration, higher cell densities, and demand for more processing power. As a result MOSFET device dimensions continue to shrink to meet these demands. A side effect of device scaling is increased variability at each technological node which affects both analog and digital circuits in terms of decreased yields, performance, and noise margins. At deep sub-micron dimensions the Low-Frequency Noise (LFN) of the MOSFET is dominated by the influence of one or more active traps capturing and emitting charge to and from the oxide creating wide variations in the LFN from otherwise identical devices. Additionally, the random position of dopant atoms near the Si/SiO2 interface create a potential landscape that induces regions of high and low conductivity which in turn causes a situation where the current is no longer uniform in the device, but consist of individual current paths or percolating currents. The coupling between the random variation of the percolation current and active traps in the oxide are responsible for the large spread (> 3 orders of magnitude) in the noise characteristics observed in deep sub-micron MOSFET devices. The compact LFN model presented here accounts for the action of traps on percolating currents in deep-sub-micron and nano-scale MOSFETs. Two schemes for reduction of LFN are studied based on the smoothing of the surface potential. First, noise reduction is demonstrated with measurements on sub-micron MOSFETs with forward substrate bias. Secondly, the model is further verified through the reduction of noise by the removal of dopant atoms near the Si/SiO2 interface of the device. Both schemes result in a lower noise and threshold device. Finally, these experimental findings are applied to a 2.2um 2 MP CMOS image sensor. From the temporal noise measurements on threshold implant process splits, the image sensor noise has been significantly reduced as a direct result of fundamentals described by this MOSFET LFN model and further proves the validity of these findings.

This book was released on 2013-10-07 with total page 209 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides analysis and discusses the design of various MOSFET technologies which are used for the design of Double-Pole Four-Throw (DP4T) RF switches for next generation communication systems. The authors discuss the design of the (DP4T) RF switch by using the Double-Gate (DG) MOSFET, as well as the Cylindrical Surrounding double-gate (CSDG) MOSFET. The effect of HFO2 (high dielectric material) in the design of DG MOSFET and CSDG MOSFET is also explored. Coverage includes comparison of Single-gate MOSFET and Double-gate MOSFET switching parameters, as well as testing of MOSFETs parameters using image acquisition.

Download or read book New Processes and Technologies to Reduce the Low Frequency Noise of Digital and Analog Circuits written by Philippe Gaubert and published by . This book was released on 2016 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The chapter is intended to provide the reader with means to reduce low-frequency noise in Metal-Oxide-Semiconductor Field-Effect-Transistor (MOSFET). It is demonstrated that low-resistivity source and drain electrodes can greatly lower the low-frequency noise level by suppressing their contribution to the total noise. Furthermore, new plasma processes having the advantages to work at low electron temperature can achieve a further reduction, thanks to the fabrication of a better gate oxide and to a reduction of damages generally induced by conventional plasma processes. Reducing the impact of the traps on the carrier flowing inside the channel by burying the channel can also achieve a reduction of the noise level, but unfortunately at the cost of a degradation of the electrical performances. Finally, the noise analysis of the low-frequency noise in accumulation-mode MOSFETs showed that these newly developed devices have a lower noise level than conventional structures, which, in addition to their superiority in term of electrical performances, establishes them as a serious platform for the next Complementary Metal-Oxide-Semiconductor Field-Effect-Transistor (CMOS) technology.

Available in PDF, EPUB and Kindle. Book excerpt: "Following their first observation in 1984, random telegraph signals (RTSs) were initially a purely scientific tool to study fundamental aspects of defects in semiconductor devices. As semiconductor devices move to the nanoscale however, RTSs have become an issue of major concern to the semiconductor industry, both in development of current technology, such as memory devices and logic circuits, as well as in future semiconductor devices beyond the silicon roadmap, such as nanowire, TFET and carbon nanotube-based devices. It has become clear that the reliability of state-of-the-art and future CMOS technology nodes is dominated by RTS and single trap phenomena, and so its understanding is of vital importance for the modelling and simulation of the operation and the expected lifetime of CMOS devices and circuits. It is the aim of this book to provide a comprehensive and up-to-date review of one of the most challenging issues facing the semiconductor industry, from the fundamentals of RTSs to applied technology."--Prové de l'editor.
