The distribution of the threshold voltage Vth after NBTI stress originates from a convolution of the distribution of the virgin devices together with the additional distribution of the NBTI degradation itself. The variability of the Vth (and other electrical parameters) of the virgin devices bases on process induced fluctuations of dopant atoms, oxide thickness, channel length, etc. The dependence on the transistor size is proven by several publications [e.g. 1,2]. The variability of the NBTI parameter degradation itself and the convolution is not fully understood yet and need further investigation. In this paper we investigate the dependency of the NBTI variability of Vth on the transistor size and geometry. For the necessary statistical relevance we perform NBTI stress experiments with the help of a smart array test-structure at a large amount of pMOS devices with various geometries. We show that the variability of pMOSFETs after NBTI depends not only on the size of the active area (w×l) but also on its geometry (w/l).","PeriodicalId":120239,"journal":{"name":"2015 IEEE International Integrated Reliability Workshop (IIRW)","volume":"143 10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129392075","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}

However, conventional CP methods are not effective for modern highly scaled devices due to high gate leakage current to CP current ratios. Fortunately, a newly developed CP technique has been developed, called frequency modulated CP (FMCP), which overcomes the limitations of conventional measurements and permits full CP studies to be successfully applied to highly scaled devices. In this work, we evaluate the practicality and usefulness of implementing FMCP to characterize Intel's second generation 14nm tri-gate MOSFETs. This demonstration clearly highlights FMCP's power and ability to provide critical information in current and future highly scaled technology nodes.","PeriodicalId":120239,"journal":{"name":"2015 IEEE International Integrated Reliability Workshop (IIRW)","volume":"111 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125547759","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}

A powerful tool in the form of a Smart-array circuit is designed to serve the BTI characterization needs on an industrial scale, where time plays an important role. The Smart-array circuit is designed such that 700 pMOS and nMOS transistors can be measured using the concept of pipelining. A significant reduction of up to 88.5% in time is demonstrated by establishing a pipeline of 15 pMOS transistors and the Measure-Stress-Measure (MSM) scheme of choice.","PeriodicalId":120239,"journal":{"name":"2015 IEEE International Integrated Reliability Workshop (IIRW)","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129258508","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}

Investigation of time-dependent variability at the individual trap level, e.g. in production environments, is not feasible with approaches such as single device measurements developed in the academic literature. Nonetheless, nFET and pFET time-dependent variability, in addition to standard time-zero variability, can be fully characterized and projected using a series of measurements on a large test element group. The statistical distributions encompassing both BTI and RTN variability and their correlations are discussed from a defect-centric perspective.","PeriodicalId":120239,"journal":{"name":"2015 IEEE International Integrated Reliability Workshop (IIRW)","volume":"99 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116003264","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}
