By means of novel 3-D Kinetic Monte Carlo TCAD reliability simulation technology we tracks the time dependent variability associated with granular charge injection and trapping on pre-existing or stress generated oxide traps. For the first time we take into account the interactions between the statistical variability of the `virgin' transistors introduced by the discreteness of charge and granularity of matter and the stochastic nature of the traps distribution and the trapping process itself. Throughout these 3D statistical TCAD techniques we derive the distribution of threshold voltage shift and degradation time constants in conventional bulk, SOI and FinFET transistors.","PeriodicalId":101858,"journal":{"name":"2014 International Conference on Simulation of Semiconductor Processes and Devices (SISPAD)","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-10-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114859299","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Mostly, these models have been developed independently and without considering that they may be caused by the same physical phenomenon. However, new experimental techniques have emerged, which are capable of studying these reliability issue on a microscopic level. One of them is the time-dependent defect spectroscopy (TDDS). Its intensive use has led to several interesting findings, including the fact that the recoverable component of BTI is due to reaction-limited processes. As a consequence, a quite detailed picture of the processes governing BTI has emerged. Interestingly, this picture has also been found to match the observations made for other reliability issues, such as random telegraph noise, 1/f noise, as well as gate leakage currents. Furthermore, the findings based on TDDS have lead to the development of capture/emission time (CET) maps, which can be used to understand the dynamic response of the defects given their widely distributed parameters.","PeriodicalId":101858,"journal":{"name":"2014 International Conference on Simulation of Semiconductor Processes and Devices (SISPAD)","volume":"225 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-10-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115104982","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We studied its operational limits and current dependent characteristics. Since flip flops are commonly operated by clocked signals, their operation is time critical and the knowledge and understanding of their switching behavior is essential. In this work we study the dependence of the proposed flip flop on its device geometry. In order to facilitate the comparison to the previous results, the same device parameters are employed. The current density was fixed for both inputs at a value of 7 × 1010 A/m2, where all flip flops safely operated, and the free layers' dimensions were varied, independently. The free layer thickness was found as the most critical parameter affecting the switching time, followed by the layer length and a negligible dependence on width.","PeriodicalId":101858,"journal":{"name":"2014 International Conference on Simulation of Semiconductor Processes and Devices (SISPAD)","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-10-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130631560","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
