A characteristic of solder bumps is that during technology processing and usage their material composition changes. This compositional transformation is enhanced by electromigration and leads to the formation of voids which can cause a complete failure of a solder bump. In this paper we present a compact model for prediction of the mean-time-to-failure of solder bumps under the influence of electromigration.","PeriodicalId":101858,"journal":{"name":"2014 International Conference on Simulation of Semiconductor Processes and Devices (SISPAD)","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-10-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121239348","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 hydrogen atom is attached to a dangling bond which is well separated from other dangling bonds, whereas it is not attached to ones which strongly interact because of lattice distortion. An electron trap level caused by nitrogen vacancy becomes shallow by hydrogen incorporation. An electron is trapped in a deep level created by a silicon dangling bond before hydrogen incorporation, whereas it is trapped in a shallow level created by an anti-bonding state of a siliconsilicon bond after hydrogen incorporation. The simulation results qualitatively explain the experiment in which reduced hydrogen content in silicon nitride shows superior retention characteristics of the programmed state.","PeriodicalId":101858,"journal":{"name":"2014 International Conference on Simulation of Semiconductor Processes and Devices (SISPAD)","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-10-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133900903","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 model has been implemented as part of the Vienna-Schrödinger-Poisson simulation and modeling framework. The transport formalism is based on the quantum transmitting boundary method. A new approach to reduce its computational effort has been realized. The model has been used to achieve a consistent treatment of quantization and transport effects in deeply scaled asymmetric GaN HEMTs.

A physical model interface (PMI), accounting for the temperature dependence of the thermal boundary resistance (TBR), has been implemented in the simulator in order to realistically model self-heating effects. In particular, we take into account for the TBR associated to the nucleation layer between GaN and SiC substrate. Moreover, the thermal contribution of the mutual heating among adjacent devices has been considered. Finally, we have investigated the influence of the temperature on the surface charges trapping and de-trapping phenomena showing two different traps occupancy transients.
