At 500 V applied reverse voltage, hot spots have been revealed near the junction periphery at 220 °C temperature. These hot spots are attributed to non-uniform leakage current flow at the junction periphery. At higher applied voltage these small overheated regions can initiate reverse electrical characteristic instability followed by failure. Further advance in the junction passivation process from device technology is required to provide high quality semiconductor-dielectric interface. This could enable reliable operation of some power silicon devices above 200°C junction temperature.","PeriodicalId":377326,"journal":{"name":"CAS 2010 Proceedings (International Semiconductor Conference)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121381640","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}

This efficient procedure is easy to implement combining robust design of G-S-G (Ground-Signal-Ground) test structures and accurate on-wafer characterizations, and it is in particular suitable for modeling of high frequency VCOs fabricated in advanced CMOS and BiCMOS technologies. The methodology allows the extraction of LC-tank capacitors including all RLC-tank parasitics and therefore features an important increase of modeling accuracy. The method has been validated in the case of several LC-tanks (oscillating between 6 and 10GHz). The tank inductors and capacitors have been characterized on-wafer up to 50GHz.","PeriodicalId":377326,"journal":{"name":"CAS 2010 Proceedings (International Semiconductor Conference)","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128424897","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}

One reason is that AuNP exhibit an optical response dominated by the localised surface plasmon resonance (LSPR) that is highly sensitive to the molecular environment. This paper describes the preparation of monodisperse supported AuNP and their characterization by optical UV-visible spectroscopy. It is shown how the surface density of AuNP can be extracted from the spectra, using a complementary check against AFM images. An example of a plasmonic biosensor capable of the specific recognition of avidin is presented.","PeriodicalId":377326,"journal":{"name":"CAS 2010 Proceedings (International Semiconductor Conference)","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127735358","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}

For specialized devices operation is permitted in specified conditions. Reverse electrical characteristics including the breakdown region for typical devices are presented and analyzed. A breakdown region caused by current flow in the bulk, due to carrier avalanche multiplication is exhibited for specialized devices from room temperature up to 150 °C. Nonetheless above 150 °C because of high level of leakage current flow at the interface from passivated termination, device failure may take place before the avalanche bulk breakdown is reached. For other devices even at lower temperature, excessive flow of current at the interface is a limitation to reach the avalanche bulk breakdown.","PeriodicalId":377326,"journal":{"name":"CAS 2010 Proceedings (International Semiconductor Conference)","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128656071","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}
