Device simulation of the electrical characteristics in 14nm gaussian channel junctionless finfet
Get PDFIn conventional FinFET, it becomes difficult to define the doping concentration of material over a distance shorter than 10nm and produce high-quality junctions for sub 20nm regime which leads to short channel effects. Hence, Junctionless FinFET which offers architecture, free from any p-n junction is able to overcome the short channel effects. JL FinFET acts like a gated resistor and it has uniform high doping (~ 1019 to 1020 cm-3) from source to drain throughout the silicon channel to maintain a high drive current in ON state. The prominent advantages of this device include low leakage current, low parasitic capacitance, reduced Drain Induced Barrier Lowering (DIBL), and excellent Ion/ Io f f ratio which made them a viable option for low-power logic applications. Apart from their advantages, the most important issue for the fabrication of Junctionless devices is achieving a uniform doping concentration in the device layer, especially in non-planar structures like FinFET. In FinFET, doping of the fin region has to be performed in a 3D fashion which results in non-uniform doping around the fin. Hence the most general doping profile is the Gaussian which is considered as a solution for this doping concern. This work presents the design and optimization of the 14nm Gaussian Channel Junctionless FinFET (GC-JLFinFETs) using Silvaco TCAD simulator. In this study, the results are validated using the conventional FinFET and the structure is optimized to improve the ON current (Ion) with a simultaneous decrease in the OFF current (Io ff), Subthreshold Swing (SS), and Drain-Induced Barrier Lowering (DIBL). Hence the structure is optimized with respect to the device parameters such as high-k spacer dielectric, low-k gate dielectric, and spacer width. The Gaussian doping profile in JL-FinFET structure is analyzed with the peak of 4 x 1019 cm-3 placed at the sidewalls of Fin and gets reduced gradually towards the center of the Fin with the standard deviation of 1nm/dec. The gate work function of all the configurations of FinFET was adjusted to obtain a 400mV threshold voltage for a meaningful comparison. In order to further reduce the leakage current of the device, Punch Through Stop Layer (PTS layer) has been added beneath the channel. The IV characteristics are simulated for both n- and p-type FinFET exhibits good compliance with the experimental results of Intel. For a fair device simulation, the device is carefully calibrated using the experimental results thus validating the simulation results. The simulated values interpret that the Ion=101.5^A/ |im is obtained for the simulated device structure. The simulated design shows better efficiency in terms of short channel characteristics namely DIBL= 25.3 mV/V, SS = 63.88 mV/dec, Transconductance =3.621x105 S/^m, and the overall efficiency of the device is improved by 25.63%. The work is further extended to its application in inverter circuits using the SPICE simulator to analyze the circuit level performance of the simulated structure. In SPICE level, the circuit is subjected to DC and transient analysis for its feasibility in real-time application of the device, and the obtained improvement is 42.58%

Making sense of ‘new age data sets’: researching from afar
No full textThis chapter considers the central role of uncertainty for cognition and action in construction project organising with a focus on how project practitioners think about the future. It takes a cognitive approach to uncertainty in the context of a broader information processing approach to decision-making in organisations. The chapter’s main concern is the failure of this approach to connect cognition through to action. The chapter presents the UnCoCoH (Un-Certain Complex Complicated Hidden) model as a tool to assist in recognising the transition from individual cognition to collective action. It also highlights the role of narratives for stabilising uncertainty through this transition. This provides a foundation for working towards the development of a projectivity perspective in construction project organising and advancing a research agenda for this program of research.Green Open Access added to TU Delft Institutional Repository ‘You share, we take care!’ – Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Integral Design & Managemen
Decompression escharotomies of burns in children between the ages 0 and 18 years
No full textFull thickness burns in children often leads to eschar formation which requires escharotomy. Escarotomies in children pose various challenges depending on the site involved, age of the child, mechanism of injury etc. In this article we discuss a series of children under special circumstances who required escharotomies. We are describing the methodology used and precautions to be taken before and after surgical procedure to improve the outcome in these children
Exfoliative diseases of the integument and mucous membrane that mimic deep 2nd-degree burns with or without sepsis
No full textIntroduction: Exfoliative skin diseases in children can mimic burns in many ways and require early diagnosis and management. Here we enumerate the different skin conditions with four case based examples and their management.
Clinical Presentation: Varying degrees of skin involvement may be seen with severe involvement in DRESS syndrome and milder involvement in Stevens-Johnson syndrome. Management: The management of this exfoliative lesion is the application of collagen membrane to the wound as we treat burns. Although systemic symptoms can produce mortality (e.g., dress), collagen dressing heals the wound well with good epithelialization. Early and appropriate antibiotic therapy is mandatory.
Conclusion: Careful attention to correct diagnosis, early intervention and use of collagen dressing have improved outcome in these children
