This problem can be dealt with using real-time error-compensation method that combines measured temperatures with knowledge of thermo-elastic properties of the precision system. The thermally induced time varying deformations are calculated real-time by the error compensation model based on measured temperatures. The gained performance depends on the uncertainty of the thermo-mechanical model, the configuration of the temperature sensors and uncertainties in the temperature measurements. In the paper a method is introduced that enables optimization of the sensor configuration and accompanying compensation model based on the modal reduction technique. This method can be used in cases where only little pre-knowledge of heat-loads are available and enables a more optimal sensor placement, thus improving the performance of the error-compensation method.","PeriodicalId":264943,"journal":{"name":"2007 13th International Workshop on Thermal Investigation of ICs and Systems (THERMINIC)","volume":"226 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":"115745436","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 local temperature of the chip was deducted according to temperature coefficient of resistance. Also, this temperature was inspected by a thermal infrared mapping technique. It is suggested that the heat accumulation within first-level solder interconnections was highly related to the current density. During the electromigration process, Pb migration was apparently visible because of its faster diffusivity. Meanwhile, voids were initiated at the entry location of the electron flow due to the current crowding effect. Numerical simulation also predicted a local current density of above 105 A/cm2 within the solder joint In the thermomigration process, the transport of Pb was detected owing to the thermal gradient across the solder joint. Voids also occurred at the contact window due to accelerated atomic diffusion. In addition, the effect of electromigration and thermomigration on the mechanical behavior of the solder joint was examined through shearing tests.","PeriodicalId":264943,"journal":{"name":"2007 13th International Workshop on Thermal Investigation of ICs and Systems (THERMINIC)","volume":"4 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":"131095390","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}
