The basic idea is to split the substrate in basic elements of length ΔL and to associate to each element, lumped thermal resistances. The proposed model is validated by comparison with electro-thermal numerical simulations in silicon Power MOSFET technology. The proposed thermal network accurately predicts the temperature increase as a function of the distance from the heat source.","PeriodicalId":146779,"journal":{"name":"Ulis 2011 Ultimate Integration on Silicon","volume":"163 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-03-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114317254","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 device is called ”junctionless” [3] because it contains a uniform doping level (n<sup>+</sup> n<sup>+</sup> n<sup>+</sup> for nFETs or p<sup>+</sup> p<sup>+</sup> p<sup>+</sup> for pFETs) within the whole device including source, drain, and channel, which is different from the non-uniform n<sup>+</sup> pn<sup>+</sup> (or p<sup>+</sup> np<sup>+</sup>) doping profiles in conventional nMOSFETs (or pMOSFETs). Therefore, during the fabrication the doping profile in junctionless nanowire pinch-off FETs is easier to control than in the conventional MOSFET case, especially for sub-100 nm gate length devices [3]. In additions, junctionless pinch-off FETs operate similar to JFETs and inversion is not required. In order to turn off the device, a sufficiently large |V<inf>GS</inf>| is required to extend the depletion region until pinch-off occurs. This is the reason for the name ”pinch-off” FET. If the horizontal cross-section area of the nanowire is scaled, the doping level must be increased in order to keep the threshold voltage unchanged [1]. Due to the high doping levels (typically 10<sup>18</sup> cm<sup>−3</sup> to 5 × 10<sup>19</sup> cm<sup>−3</sup>) the carriers are strongly influenced by ionized impurity scattering, and as a consequence, the channel effective mobility is low. Therefore, it is important to include stress/strain engineering in combination with non-standard crystallographic channel orientations to boost the transport performance of the junctionless nanowire pinch-off FET.","PeriodicalId":146779,"journal":{"name":"Ulis 2011 Ultimate Integration on Silicon","volume":"31 4","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-03-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132359765","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}
