Virtually or hybrid format in Kyoto

IITC 2021 Call for Paper

Paper submission site is closed on March 21 (JST UCT+0900), 2021

The 24th edition of IITC is sponsored by the IEEE Electron Devices Society and is co-sponsored by the Japan Society of Applied Physics as the premier conference for interconnect technology devoted to leading-edge research in the field of advanced metallization and 3D integration for ULSI applications.

IITC 2021 will be held in hybrid format comprising a virtual and in-person meeting (Kyoto Research Park, Kyoto, Japan), July 6-9, 2021.
The conference seeks papers on all aspects of BEOL/MOL/3D interconnects and metallization, including design, unit process, integration, and reliability. Authors are encouraged to submit their original work describing innovative research and development in the critically important field of on-chip interconnects and heterogeneous integration.

• Regular papers, with 3-page abstracts, will be selected for either oral or poster presentation.
• A 2-page abstracts option, e.g., from students and young scientists, will undergo the same review process but will be accepted only for poster presentation.
• All submissions are rigorously reviewed.
• The conference proceedings will be submitted to the IEEE Xplore Digital Library®.


Prior to the technical program, a workshop on “Metallization Technologies and Their Applications in IoT and AI Devices” by seven leading experts will be held on July 6. The technical program will feature exciting talks by 2 keynote speakers and 13 invited speakers.
