XPS studies confirmed that the films annealed above 700 °C showed the best stoichiometry (Ta<sub>1.96</sub>O<sub>5.04</sub>) compared to the as deposited film and the films annealed till 600 °C. XRD spectra confirmed the amorphous nature of the as deposited film, which remained amorphous till 600 °C and became polycrystalline above 700 °C. The EIS device showed the maximum sensitivity of 51.4mV/pH for the film annealed at 700 °C, while the device with the as deposited film had a sensitivity of 44.3mV/pH. Further increase in annealing temperature above 700 °C resulted in reduced sensitivity (31.0mV/pH) because of increased interface states (indicated by C-V hysteresis in a MOS device) and enhanced cracks formation in the films (indicated by FESEM). Therefore, the annealing temperature of 700 °C was found to be the optimum annealing temperature for the e-beam deposited Ta<sub>2</sub>O<sub>5</sub> films.","PeriodicalId":6520,"journal":{"name":"2015 2nd International Symposium on Physics and Technology of Sensors (ISPTS)","volume":"67 1","pages":"214-218"},"PeriodicalIF":0.0,"publicationDate":"2015-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86852392","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}

These requirements calls for enhanced properties of the present solder materials. Appropriate reinforcements in the existing solder material will help in achieving much improved electrical, mechanical and thermal properties. Carbon Nano Tubes (CNTs) are one such material that can bring in considerable improvements in the properties of the solder material. CNT-Solder composite with less than 1% CNT is being explored for solder bumps in flip chip applications. This paper reports our work on co-deposition of CNT along with lead-free solder using electroplating process. For co-deposition of CNTs along with the solder, the processing of CNT is very important. Milling and CNT functionalisation are two such parameters that aid in its dispersion and make it active. The present studies include optimization of milling time for CNTs and selection of appropriate activators for functionalisation of CNTs in the electroplating bath.","PeriodicalId":6520,"journal":{"name":"2015 2nd International Symposium on Physics and Technology of Sensors (ISPTS)","volume":"10 1","pages":"120-124"},"PeriodicalIF":0.0,"publicationDate":"2015-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90606089","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}

It integrates sensor data with models that enable in-situ assessment of the “health” (e.g. deviation or degradation) of a system from an expected normal operating condition and also predicts the future state of the system based on current and historic conditions. This presentation discusses some methods used for anomaly detection and prognostics, including the monitoring and reasoning of parameters that are precursors to impending “failure”, such as shifts in performance parameters; and the modeling of stress and damage utilizing life cycle loads (e.g., usage, temperature, vibration, radiation).
