项目摘要

PROJECT ABSTRACTProposal Title:Negative Capacitance: Scientific Facts or Fiction - A Thorough Examination of Ferroelectric-Gated Field-Effect Transistor ModelsNontechnical AbstractThe concept of “negative capacitance” (NC), recently brought to light, is one of the most novel and exciting ideas that emerged in the last decade or so in the semiconductor community, as it promises to enable field-effect transistor (FET) integrated circuits (ICs) to perform at speeds exceeding the limit predicted by the conventional theory, even with reduced power consumption. Consequently, many researchers and engineers throughout the world have been actively working on various aspects of NC transistors since its introduction, resulting in numerous publications with varying degrees of quality and sensibility. The research reports have caused wide spread confusion and conflicting conclusions. The objective of this research is to obtain a comprehensive understanding of the NC model of ferroelectric-gated FETs by conducting a thorough investigation of all aspects of this topic, and to disseminate widely the findings with a goal to foster its healthy development in the semiconductor community.Technical AbstractTo achieve this objective, an exhaustive study of the published literature will be made to thoroughly investigate both theoretical and experimental aspects of negative capacitance models of ferroelectric-gated field-effect transistors (FeFETs) in order to identify and to articulate valid as well as false claims. Many cleverly constructed experiments are proposed to confirm or debunk the prevailing NC models of FeFETs, and to convincingly expose the false claims as supported by the revelation of their underlying causes.The intellectual significance of this project stems from the fact that it addresses an issue of both intense scientific interest and significant technological importance. On the scientific side, the NC model is one of the most striking ideas in the last decade or so, which have generated intense interests in the semiconductor community worldwide. On the technological side, the NC associated with FeFETs promises to provide a very low subthreshold-swing solution just when the conventional scaling based on the Moore’s Law is nearing its end. The findings of this study are intended to provide an important and unbiased reference, if not the key reference, for the study of the negative capacitance in the context of FeFETs for next-generation integrated circuits.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

项目摘要提案标题：负电容：科学事实或虚构 - 对铁电门控场效应晶体管模型的彻底检查非技术摘要最近曝光的“负电容”（NC）概念是过去十年左右半导体界出现的最新颖、最令人兴奋的想法之一，因为它有望实现场效应晶体管（FET）集成电路（IC）的执行速度超过传统理论预测的极限，即使功耗降低。因此，自 NC 晶体管问世以来，世界各地的许多研究人员和工程师一直在积极研究 NC 晶体管的各个方面，从而产生了大量质量和敏感性不同程度的出版物。这些研究报告引起了广泛的混乱和相互矛盾的结论。本研究的目的是通过对该主题的各个方面进行深入研究，全面了解铁电栅 FET 的 NC 模型，并广泛传播研究结果，以促进其在半导体领域的健康发展。技术摘要为了实现这一目标，将对已发表的文献进行详尽的研究，以深入研究铁电栅 FET 的负电容模型的理论和实验方面。铁电门控场效应晶体管 (FeFET)，以便识别和阐明有效和错误的主张。人们提出了许多巧妙构建的实验来证实或揭穿流行的 FeFET NC 模型，并令人信服地揭露错误的主张，并揭示其根本原因。该项目的学术意义源于以下事实：它解决了一个既具有强烈的科学兴趣又具有重大技术重要性的问题。在科学方面，数控模型是过去十年左右最引人注目的想法之一，它引起了全球半导体界的强烈兴趣。在技术方面，当基于摩尔定律的传统缩放技术接近尾声时，与 FeFET 相关的 NC 有望提供非常低的亚阈值摆幅解决方案。这项研究的结果旨在为下一代集成电路 FeFET 背景下的负电容研究提供重要且公正的参考，即使不是关键参考。该奖项反映了 NSF 的法定使命，并通过使用基金会的智力价值和更广泛的影响审查标准进行评估，被认为值得支持。
