Resonac Launches R&D Center for Next-Gen Semiconductor Package Technology under U.S.-Japanese Consortium “US-JOINT”

Opening Ceremony

The new R&D center is the first in the United States dedicated to developing advanced semiconductor-packaging technologies. Resonac and the consortium partners will leverage this R&D base in Silicon Valley to validate new concepts in collaboration with major users of advanced semiconductors. By capturing market needs in real time and combining the technological capabilities of leading Japanese and U.S. manufacturers of materials and equipment, the consortium will accelerate the research and development of materials, evaluation and packaging technologies to enable the rapid commercialization and deployment.

Hidehito Takahashi, President and CEO of Resonac, commented: "US-JOINT aims to shorten the proof-of-concept (PoC) period from approximately six months to as little as one month by enabling 12 participating Japanese and U.S. companies to conduct development in Silicon Valley, home to major hyperscalers. Through “collaboration” between semiconductor-related companies from Japan and the United States, the initiative will accelerate global semiconductor innovation."

Resonac will leverage US-JOINT's technological foundation and knowledge to play a central role in promoting co-creation while overseeing the consortium. As a materials manufacturer with a comprehensive understanding of the entire semiconductor manufacturing process, Resonac will bring together the technologies and ideas of participating companies to contribute to concept validation and accelerate co-creation targeted at market needs.

Dilip Vijay, Vice President and Head of Global IC Operations, Broadcom Inc., commented: "A collaborative effort like US-JOINT is exactly what the industry has needed. I am very much looking forward to the US-JOINT R&D center's full-scale operation in Silicon Valley. We expect this initiative to speed up semiconductor innovation and spark entirely new breakthroughs beyond what we see today."

Raja Swaminathan, Vice President of Heterogeneous Integration Technologies, Advanced Micro Devices, Inc., said: "With US-JOINT now fully operational in Silicon Valley, we expect face-to-face technical dialogue to lead to more efficient joint development through faster feedback and clearer understandings. We welcome US-JOINT’s efforts and look forward to the innovations and strengthened ecosystem collaboration this initiative can enable."

Kazumi Nishikawa, Director-General for Economic Security Policy, Trade and Economic Security Bureau, Ministry of Economy, Trade and Industry, remarked: “The expansion of generative AI and the current requirements of computing demands more advanced packaging. I am very confident that US-JOINT is just the start of innovation for advanced packaging and chiplets in generative AI computing. Finally, I truly appreciate the effort that led to today, and I hope that today's one step can lead to a tremendous outcome for the U.S. and Japan and to the world.”

• The latest milestone in technological collaboration and industry leadership
  Resonac is a world-leading supplier of semiconductor materials essential for each stage of semiconductor manufacturing. It also has a proven track record of promoting co-creation with material and equipment manufacturers in other consortia, including JOINT2 and JOINT3. Going forward, Resonac will leverage its operational capabilities and industry trust as a materials manufacturer to accelerate the efforts of US-JOINT and related collaborators to develop next-generation semiconductor packages.
  Advanced semiconductor packaging and improved performance support growth in key sectors, including generative AI and autonomous driving. Notably, new packaging concepts are emerging as major IT firms and hyperscalers begin designing their own custom AI semiconductors. A limited environment for rapid, practical validation has been a bottleneck in technology development, but consortium partners anticipate that US-JOINT will significantly accelerate validation trials and offer new packaging technologies moving forward.
