One solution for dishing phenomenon is introduction of metal pattern fill with dummy structures as a method to improve planarity for a given layer. This paper deals with the optimization of planarity and parasitic capacitance. Wafer level topography maps illustrates the planarity of circuit without pattern fill. Parasitic capacitance analysis is performed by closed form solution. Using the analysis of the circuit-level parasitic capacitance tool, the estimated effect on various circuit nets is calculated.","PeriodicalId":369241,"journal":{"name":"International Semiconductor Device Research Symposium, 2003","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2004-05-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115533632","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 results are obtained with a log-periodic circular-toothed antenna having a 6-finger photomixer at the driving point. The optical power sweep data are obtained at a frequency of 0.5 THz and a bias voltage of 20 V. At the maximum optical power of 26 mW, the recorded lock-in signal corresponds to a THz power level of /spl ap/ 50 nW. The lock-in signal which is directly proportional to the THz power shows the characteristic quadratic behavior at low optical power levels.","PeriodicalId":369241,"journal":{"name":"International Semiconductor Device Research Symposium, 2003","volume":"47 4","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2004-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114122519","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 present calculation is based upon the determination of the 2DEG concentration by solving Schrodinger and Poisson's equations self-consistently as well as incorporating non-stationary transport to obtain the carrier velocity-electric field characteristics. Charge control is obtained by accounting for the total polarization in the barrier AlGaN layer and the GaN layer at the heterointerface. Device nonlinearity has been analyzed using Volterra Series technique which shows the output referred third-order intercept point (OIP3), referred as the output power level at which third-order intermodulation component of the output power crosses the fundamental component. the third-order intermodulation is also achieved at higher barrier thickness. A higher IM3 is also achieved at higher Al-mole fraction.","PeriodicalId":369241,"journal":{"name":"International Semiconductor Device Research Symposium, 2003","volume":"81 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2003-12-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124902765","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}
