Germanium-rich as well as Tellurium-rich phase-change materials have been integrated in simple test devices and programming characteristics, data retention and endurance performances are thoroughly analyzed. Tellurium-rich GeTe alloys exhibit stable programming characteristics that can sustain endurance test up to 1e7 cycles, while Germanium-rich GeTe, probably triggered by Ge segregation, shows an unstable RESET state during repeated write/erase cycles. Data retention on fresh devices is best for out-of-stoichiometry GeTe.","PeriodicalId":161896,"journal":{"name":"2011 Proceedings of the European Solid-State Device Research Conference (ESSDERC)","volume":"1 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":"125842469","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}

MOSFETs with different trench depths are fabricated and characterized. Measurements show that gate charge and capacitance increases with trench depth thereby increasing switching losses. However, conduction losses reduce with increasing trench depth because of higher gate-modulated accumulation charge at the drain. Since switching losses increase with frequency, the trade-off between the conduction and switching losses for different trench depths will be determined by the switching frequency. In conclusion, deep-trench MOSFETs outperform shallow-trench MOSFETs at low frequencies and become outperformed by the latter at high frequencies.","PeriodicalId":161896,"journal":{"name":"2011 Proceedings of the European Solid-State Device Research Conference (ESSDERC)","volume":"9 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":"128279745","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 pure Schottky-barrier junction, the overlap between source/drain and gate is critical. A 2-nm underlap results in high tunneling resistance and thus poor programming efficiency. Suitable designed modified-Schottky-barrier junction can improve programming speed by Fowler-Nordheim tunneling while keeping erase and retention performance unaltered. The main degradation mechanism during endurance test is attributed to interface state generation and tunneling layer degradation. After improving the quality of the tunneling layer, the modified Schottky barrier junction would be a promising choice for 3-dimentional poly-Si memory.","PeriodicalId":161896,"journal":{"name":"2011 Proceedings of the European Solid-State Device Research Conference (ESSDERC)","volume":"1 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":"130766591","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}

Simulations performed with a realistic model for source/drain metal contacts indicate that a proper choice of the drain doping profile can partially suppress BTBT currents.

With significant dark random noise reduction, in order to evaluate the performance for perspective space or medical imaging application, this proposed pixel structure using 0.18μm CMOS image sensor process is also further characterized under X-ray radiation. The results show that although X-ray radiation induced additional acceptor-like interface traps will increase dark random noise, the BSF pixels are able to constrain the dark random noise increase after X-ray radiation.","PeriodicalId":161896,"journal":{"name":"2011 Proceedings of the European Solid-State Device Research Conference (ESSDERC)","volume":"24 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":"129526975","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}

In this paper we characterize a 160×128 array of complex pixels, each with a single-photon avalanche diode (SPAD) and a time-to-digital converter (TDC). A study of the array's non-uniformities in terms of the timing resolution, jitter, and photon responsivity is conducted for the pixels at various illumination levels, temperatures, and other operating conditions. In the study we found that, in photon-starved operation, the TDCs exhibit a median resolution of 55ps and a standard deviation of 2 ps. The pixels show a median timing jitter of 140ps. Moreover, we measured negligible variations in photon responsivity while changing the number of active pixels. These findings suggest that the image sensor can be used in highly reliable, large-scale, time-correlated measurements of single photons for biological, molecular, and medical applications. The chip is especially valuable for time-resolved imaging, single-photon counting, and correlation-spectroscopy under many realistic operating conditions.","PeriodicalId":161896,"journal":{"name":"2011 Proceedings of the European Solid-State Device Research Conference (ESSDERC)","volume":"CATV-3 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":"132727955","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}
