The circuit elements dissipate heat, which propagates in the chip, rising the temperature of all circuit elements. Since the operation of the latter is temperature dependent, their dissipation will also change. This change results in the variation of the element voltages and currents, causing further changes in the dissipation, etc. Therefore we are facing a pair of couplings: an electronic → thermal one and a thermal → electronic one, meaning that all integrated circuits constitute essentially a mutually coupled electronic and thermal system. In this paper a detailed discussion of the electro- thermal phenomena is presented regarding the practical implementation. The final implementation is a SPICE compatible electro-thermal solver (qSPICE), which implements some of the major industry standard models with extended coupled thermal capabilities. The accuracy of qSPICE is demonstrated on multiple examples.}, year = {2012}, pages = {190-195}, orcid-numbers = {Czirkos, Zoltán/0000-0001-9269-0472} } @article{MTMT:2686137, title = {Measurement of the Time-Constant Spectrum: Systematic Errors, Correction}, url = {https://m2.mtmt.hu/api/publication/2686137}, author = {Székely, Vladimir and Szalai, Albin}, doi = {10.1016/j.mejo.2012.05.011}, journal-iso = {MICROELECTRON J}, journal = {MICROELECTRONICS JOURNAL}, volume = {43}, unique-id = {2686137}, issn = {0026-2692}, year = {2012}, eissn = {0959-8324}, pages = {904-907} } @inproceedings{MTMT:2685729, title = {Thermal Transfer Impedance Variations by Forced Convective Heat Transfer in Microchannels}, url = {https://m2.mtmt.hu/api/publication/2685729}, author = {Ender, Ferenc and Székely, Vladimir}, booktitle = {2012 SYMPOSIUM ON DESIGN, TEST, INTEGRATION AND PACKAGING OF MEMS/MOEMS (DTIP)}, unique-id = {2685729}, year = {2012}, pages = {119-124}, orcid-numbers = {Ender, Ferenc/0000-0003-3800-5707} } @article{MTMT:2679937, title = {Possible acception criteria for structure functions}, url = {https://m2.mtmt.hu/api/publication/2679937}, author = {Szalai, Albin and Székely, Vladimir}, doi = {10.1016/j.mejo.2011.08.010}, journal-iso = {MICROELECTRON J}, journal = {MICROELECTRONICS JOURNAL}, volume = {43}, unique-id = {2679937}, issn = {0026-2692}, abstract = {This paper deals with the verification of thermal transient evaluation implementations. This subject is relevant because e.g. the upcoming standard will describe the thermal transient measurement as a standard method to estimate the junction-to-case thermal resistance [1] and [2], thus anybody can create their own implementation of the evaluation method. We have to have a method to verify these implementations. For this reason we examined the result of the NID (Network Identification by Deconvolution) method from different aspects. For these examinations we defined a multilayer structure as a reference structure and we analytically expressed the unit-step response and the cumulative structure function of this structure. Using the unit-step response as an input data set for the implementation in question we got an approximation of the structure function. Analysing this and the reference RC network we could define a practical maximum tolerance for the deviation between the analytical and the calculated functions.}, year = {2012}, eissn = {0959-8324}, pages = {164-168} } @article{MTMT:2659700, title = {Blind tracing of mechanical movement in electrostatic MEMS structures}, url = {https://m2.mtmt.hu/api/publication/2659700}, author = {Székely, Vladimir and Szabó, Péter Gábor}, doi = {10.1007/s10470-010-9551-z}, journal-iso = {ANALOG INTEGR CIRC S}, journal = {ANALOG INTEGRATED CIRCUITS AND SIGNAL PROCESSING}, volume = {71}, unique-id = {2659700}, issn = {0925-1030}, year = {2012}, eissn = {1573-1979}, pages = {11-21}, orcid-numbers = {Szabó, Péter Gábor/0000-0001-7601-743X} } @inproceedings{MTMT:2675952, title = {New level of accuracy in TIM measurements}, url = {https://m2.mtmt.hu/api/publication/2675952}, author = {Vass-Várnai, András and Székely, Vladimir and Sárkány, Zoltán and Kerecsen Istvánné Rencz, Márta}, booktitle = {2011 27TH ANNUAL IEEE SEMICONDUCTOR THERMAL MEASUREMENT AND MANAGEMENT SYMPOSIUM (SEMI-THERM)}, doi = {10.1109/STHERM.2011.5767218}, unique-id = {2675952}, abstract = {The thermal management of semiconductor devices and systems has become a widely discussed topic over the past decades due to the ever increasing integration and the resulting power densities inside the packages. The increasing junction temperature is a great threat for the operation and the long-term reliability of the packaged device. One of the most important barriers in the heat conduction path is the thermal interface material. Their thermal performance significantly influences the overall thermal resistance of a system from the junction to the ambient. In this paper two approaches are described for the accurate thermal conductivity measurement of these materials; both techniques were developed in the framework of the European Nanopack project. One of them is a highly accurate, scientific method which benefits from the improvements of the semiconductor industry: the TIM is measured between two bare sensor chip surfaces. The other method is based on thermal transient testing and allows the measurement of a given grease or paste in its real environment. Both of them are capable of the measurement of highly conductive, nanoparticle based TIM materials. In this paper these two methods are explained in more details and measured results are compared with each-other. The effect of the measurement arrangement on the measured thermal resistance values is also discussed.}, keywords = {thermal resistance; semiconductor device reliability; Semiconductor devices; Transient analysis; Thermal transient testing; thermal management; thermal interface material; semiconductor industry; packaged device reliability; junction temperature; heat conduction path; TIM measurements; thermal management (packaging); Thermal conductivity measurement; semiconductor device packaging}, year = {2011}, pages = {317-324}, orcid-numbers = {Kerecsen Istvánné Rencz, Márta/0000-0003-4183-3853} } @inproceedings{MTMT:2668744, title = {Measurement of the time-constant spectrum: systematic errors, correction}, url = {https://m2.mtmt.hu/api/publication/2668744}, author = {Székely, Vladimir and Szalai, Albin}, booktitle = {Proceedings of the 17th International Workshop on THERMal INvestigation of ICs and Systems (THERMINIC'11)}, unique-id = {2668744}, year = {2011}, pages = {45-48} }
