2019 6th International Workshop on Low Temperature Bonding for 3D Integration (LTB-3D 2019) will be held from 21-25, May 2019 at Kanazawa-city, Japan.

The LTB-3D is a premier conference series sponsored by the 191st Committee on Innovative Interface Bonding Technology, Japan Society for the Promotion of Science (JSPS), and cosponsored by the IEEE EPS Japan Chapter, preceding 1st (2007), 2nd (2010), 3rd (2012), 4th (2014), and 5th (2017) in Tokyo, and in coming 2019, moving to an attractive old city, Kanazawa as WaferBond 2019 EAST in conjunction with WaferBond conferences which are held in Europe every two years: 2009 (Grenoble), 2011 (Chemnitz), 2013 (Stockholm), 2015 (Braunschweig), and 2017 (Leuven) .

This workshop is focusing on the promotion of advanced research areas related to low-temperature bonding technologies, including surface activated bonding (SAB), which realize novel device structure by heterogeneous material and device integration and lead to entirely new manufacturing approaches to 3D and module integration of semiconductor devices, photonics systems, and power electronic systems. These bonding technologies have been already used for the volume production and have potential applications in wide range of manufacturing industries. It has been attracting over 200 attendees with participants from more than 20 countries and regions worldwide. This workshop will be held as a single-track seminar to provide comprehensive information on the latest technologies and applications, as well as business opportunities.
