These reliability circuits consisted of interlocking combs of routing layers with varying widths and spaces that were representative of the design rules. These were accessed through multiplexer controlled pass gates. All addresses could be simultaneously enabled for stress biasing and addressed individually for failure detection. Once a breakdown was detected, as current leakage of the comb, each device could be addressed sequentially to find the failing structure. This was an improvement over previous designs which either grouped many devices in parallel, but could not electrically identify which device was failing, or only had a single device enabled, but suffered from poor pad efficiency. The grouping of these devices allows for simultaneous parallel stressing of each force and ground pad pair on the parametric testers. Electrical measurement showed that the same breakdown voltage values measured on this mux design were the same as standalone devices.","PeriodicalId":271839,"journal":{"name":"2018 IEEE International Conference on Microelectronic Test Structures (ICMTS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131132378","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}

Skewed ring oscillators (ROs) are used to characterize pMOFSET and nMOSFET specific RTN effects. Distributions of overall threshold fluctuation of a device have been extracted such that the simulated delay distribution matches with the measured delay distribution. For worst-case delay prediction, circuit analysis with Δντ distribution model for low temperature is necessary. Estimation results reveal that RTN amplitude decreases slightly with the increase of temperature. However, low correlation of 0.3 to 0.4 has been observed across temperatures ranging from 0 °C to 80 °C for delay paths. We find appearing and disappearing of traps across the temperature range causing the low correlation. Low correlation poses challenges in realizing robust runtime performance compensation techniques such as replica critical path based delay compensation.","PeriodicalId":271839,"journal":{"name":"2018 IEEE International Conference on Microelectronic Test Structures (ICMTS)","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125575257","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}
