TCAD simulations and electrical and optical characteristics of our realized devices support our findings. Reducing the injector size decreases the diffusion current: therefore, for a particular on current, the pn-product, and hence the radiative recombination, inside the active region increases. A comparison is made among reference large-scale, micro-size and nano-size injector p-i-n diodes. We demonstrate a 4-fold increase in electroluminescence (EL) when the injectors are scaled down to micro-size and a further 10-fold increase for nano-size injectors.","PeriodicalId":161896,"journal":{"name":"2011 Proceedings of the European Solid-State Device Research Conference (ESSDERC)","volume":"119 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-10-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116199544","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 paper gives a practical methodology to properly apply this method: first, it insists on the importance to discriminate the respective contributions of GIDL and gate tunneling in drain current. Then, an activation energy criterion is used to determine the bias conditions that are appropriate to correct application of this method. Experimental values of “tunneling” field and tunneling parameter are extracted, with better reliability than with previous methods. Reliable extractions of the GIDL parameters enable to characterize junction quality independently of junction abruptness and of the impact of traps in the bandgap. This method is successfully applied and results are in agreement with expected results.","PeriodicalId":161896,"journal":{"name":"2011 Proceedings of the European Solid-State Device Research Conference (ESSDERC)","volume":"62 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-10-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126277678","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 amplifier is derived from a transistor with a total gate periphery of 120 mm that exhibits a breakdown voltage of 600 V. The transistor shows excellent DC characteristics up to 53 A in pulsed mode. The realized amplifier shows good performance in continuous wave (CW) mode with an output power of 139 W and an efficiency of 71 % at a frequency of 13.56 MHz, respectively. In pulsed mode, the amplifier exhibits an output power of 431 W for a duty cycle of 10 % which emphasizes the potential of the AlGaN/GaN material system for ISM applications. The comparison of the obtained values with silicon-based semiconductor devices furthermore shows the impressive advantages of AlGaN/GaN-based devices for parameters like current density and power density that are for AlGaN/GaN-based devices by an order of magnitude higher.","PeriodicalId":161896,"journal":{"name":"2011 Proceedings of the European Solid-State Device Research Conference (ESSDERC)","volume":"211 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-10-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116405815","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}

Therefore, statistical device variability has to be considered in circuit design and analysis to properly estimate their impact and avoid expensive over-design. Statistical MOSFET compact modeling is required to accurately capture marginal distributions of varying device parameters and to preserve their statistical correlations. Due to limited simulator capabilities, variables are often assumed to be normally distributed. Although correlations may be captured using Principal Component Analysis, such an assumption may be inaccurate. As an alternative, Nonlinear Power Models have been proposed. Since we see some limitations in this approach, we analyze whether the multivariate Generalized Lambda Distribution is an alternative for statistical device modeling. Applying both approaches to extracted statistical device parameters, we conclude that both methods do not differ significantly in accuracy, but the multivariate Generalized Lambda Distribution is more general and less computationally expensive.","PeriodicalId":161896,"journal":{"name":"2011 Proceedings of the European Solid-State Device Research Conference (ESSDERC)","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-10-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128968414","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 paper proposes a comprehensible compact model for reliability simulation of analog integrated circuits. The proposed model includes all typical NBTI peculiarities such as relaxation after voltage stress reduction and dependence on time-varying stress voltage and temperature. Comprising both the recoverable and permanent NBTI components, the model also offers a significant accuracy improvement over existing models such as the popular Reaction-Diffusion model. It is therefore well suited for accurate circuit reliability analysis and failure-time prediction. Further, the model includes only 10 process-dependent parameters, enabling easy calibration.

The fabrication process is fully compatible with conventional high-voltage CMOS technology using shallow trench isolation (STI). The N-LDMOS has a breakdown voltage >100 volts with a maximum drain current of 4.4 mA at a channel length of 9 μm and a width of 50 μm. At drain voltage Vds = 100 V, self-heating causes a reduction in drain current up to 19% on a silicon carrier wafer and 35% on polyimide (PI) foil relative to the drain current without self heating, thus indicating power dissipation to be one of most serious issues in flexible electronics.","PeriodicalId":161896,"journal":{"name":"2011 Proceedings of the European Solid-State Device Research Conference (ESSDERC)","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-10-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125041972","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}
