A special NANOPACK session was held during the 15th International Workshop on Thermal Investigations of ICs and Systems, THERMINIC, in Leuven, Belgium, on 9th October 2009. Nine scientific papers related to NANOPACK subjects were presented and discussed by project partners and external speakers. This session was a very good opportunity to discuss and compare the different approaches, and will serve to gain new ideas to achieve the goals of the NANOPACK projects.
