Well behaved 80 nm devices with expected strain-induced electrical enhancement were demonstrated. Special emphasis was put on investigation of substrate junction leakage and source to drain leakage. In-situ doped wells and channel profiles demonstrated superior substrate junction leakage for the relaxed SiGe substrates compared to conventional implantation. The source to drain leakage in 80 nm devices was effectively reduced by increment of channel doping and rotation of the channel direction.","PeriodicalId":103959,"journal":{"name":"ESSDERC 2007 - 37th European Solid State Device Research Conference","volume":"208 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126977453","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 an arbitrary crystallographic surface orientation the two dimensional hole gas subband structure is calculated by solving the 6 times 6 koarr ldr poarr Schrodinger equation self-consistently with the electrostatic potential. Three important scattering mechanisms are included: optical phonon scattering, acoustic phonon scattering and surface roughness scattering. The model parameters are calibrated by matching the measured low-field mobility of relaxed Si on (001) Si wafers. The calibrated model reproduces available channel mobility measurements for unstrained and uniaxially strained Si on (001), (111) and (110) substrates.","PeriodicalId":103959,"journal":{"name":"ESSDERC 2007 - 37th European Solid State Device Research Conference","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126910503","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}

Voltages induced by oscillation of Al/SiC nanoresonators in a moderate magnetic filed are measured using a room-temperature tabletop setup in moderate vacuum. The dynamic range as well as the resonance frequency of the resonator can be reversibly controlled by electrothermal tuning using DC voltage. This paper presents experimental results on the resonance frequency, Q factor and dynamic range during the electrothermal tuning. As the input DC power increases, Q factor decreases due to the decrease in the resonance frequency, and SNR decreases due to the reduced amplitude or increased noise.","PeriodicalId":103959,"journal":{"name":"ESSDERC 2007 - 37th European Solid State Device Research Conference","volume":"78 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126120191","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}

A selective epitaxy technique was applied to form anode regions (SEA) for both types. These devices performed extremely well, with high-speed read/write, high lon/Ioff current ratio (>108), and low stand-by current (< 0.5 nA/cell). Write \"1\" (turn-on) and read performance were comparable for both bulk and SOI (< 100 ps). However, for write \"0\" (turn-off), the bulk type had much faster speed and lower voltage than the SOI type. In RAM operations, performance of the SOI type would be dominated by write \"0\" operation speed. These results suggest that the bulk type is more suitable than the SOI type for RAM devices that operate at highspeed.","PeriodicalId":103959,"journal":{"name":"ESSDERC 2007 - 37th European Solid State Device Research Conference","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130801875","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}

To sustain the development of new and scaled PCM technologies, a comprehensive understanding and modelling of the cell at the material, cell and large-array levels are required. This paper will address the most significant achievements in the electrothermal modelling of PCM single cell. After reviewing the transport modeling in the amorphous and crystalline phases of the chalcogenide material, we focus on the application modeling of the cell, discussing programming current minimization by geometry optimization, trade-off between programming current and readout resistance and the program disturb issue. Scaling of the PCM is extensively addressed, comparing isotropic and non isotropic scaling and the respective impact on cell reliability. The open issues for PCM physical modeling are finally pointed out.","PeriodicalId":103959,"journal":{"name":"ESSDERC 2007 - 37th European Solid State Device Research Conference","volume":"64 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123850289","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}
