Both ramped voltage stress (RVS) and time dependent dielectric breakdown (TDDB) measurements show that environmental humidity dramatically worsens the PZT reliability. Visible breakdown spots on the surface of PZT capacitors are studied in detail. The measurement results indicate that both reversible and irreversible PZT degradation/breakdown happen during TDDB. The dependence of time to breakdown on polarity of applied voltage is argued to relate to the crystal structure of PZT and the stack of the PZT capacitor.","PeriodicalId":436183,"journal":{"name":"2016 IEEE International Integrated Reliability Workshop (IIRW)","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-10-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121196456","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}

The first method modifies the front end process by forming a thick oxide in drift region-I. The process modification is achieved with a simple layout change in BCD technology. Experimental data shows this modification has significantly improved HC degradation in the LNDMOS. The second method modifies back end processes by adding a unique SiN barrier layer which we believe reduces plasma induced damage on the LNDMOS. We demonstrate the barrier layer can improve device hot carrier performance in the LNDMOS.","PeriodicalId":436183,"journal":{"name":"2016 IEEE International Integrated Reliability Workshop (IIRW)","volume":"51 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":"128295202","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}

Prevention is always better than a cure from risk control and cost management point of view. Over the last decade, foundry has been asked to provide aging aware IP and cell library to reduce customers' product development cycle. Though these libraries were well characterized but their aging behaviors were left to designers' own judgments. To integrate aging effect into static timing analysis (STA) either for synthesis or post-simulation, one needs a fairly accurate SPICE aging model which covers AC stress [1] and gate level (or standard cell level) timing shift. This demands Si-to-Simulation comparisons which will be addressed in this paper.","PeriodicalId":436183,"journal":{"name":"2016 IEEE International Integrated Reliability Workshop (IIRW)","volume":"10 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":"121118245","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}

Starting with the understanding of the RTN signal properties, a set of best practices to perform measurements and data analysis is established to guarantee reliable results and a correct ensuing physical interpretation. It will be shown that combining dedicated and careful experiments with refined data analysis and comprehensive physics simulations is hence required to enable RTN analysis as a safe and innovative investigation tool for electron devices. The effectiveness of RTN analysis as an investigation tool is demonstrated on both FinFET and resistive memory devices: the parameters of RTN as observed in the experiments performed on FinFETs allow understanding the details of the defects generation during stress in such devices; RTN analysis on RRAM allows understanding the physical origin of RTN in these devices and to estimate the physical properties of defects involved in the phenomenon.","PeriodicalId":436183,"journal":{"name":"2016 IEEE International Integrated Reliability Workshop (IIRW)","volume":"16 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":"122398111","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}

The elastic constants of copper vary considerably for different crystallographic orientations. Typically, the copper metal conductor lines in integrated circuits are polycrystalline in nature. The polycrystalline microstructure is known to impact the reliability and is yet to be thoroughly understood. In this work we used Voronoi tessellation to model the polycrystalline microstructure for the copper metal lines in test structures. Each of the grains was then assigned an orientation with distinct probabilistic texture with (111) as the preferred orientation and corresponding anisotropic elastic constants based on the assigned orientation. By subjecting the test structure through a thermal stress, we observed over 70% variation in hydrostatic stresses along the grain boundaries depending on the orientation, dimensions, surroundings, and location of the grains. This may introduce new weak points within the metal interconnects leading to failure. Hence, inclusion of microstructures and corresponding anisotropic properties for copper grains is crucial to conduct a realistic study of both the stress voiding and electromigration phenomena, especially at smaller nodes where the anisotropic effects are significant.","PeriodicalId":436183,"journal":{"name":"2016 IEEE International Integrated Reliability Workshop (IIRW)","volume":"40 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":"117235120","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}
