Samsung invests $300M in Japan AI chip packaging lab

Samsung Electronics chairman Lee Jae-yong visited the company's Advanced Package Lab (APL) in Yokohama, Japan, to review progress on advanced packaging technology for AI semiconductors. The facility, officially opened in September, focuses on developing materials and processes for integrating multiple chips into single packages. Samsung is investing 40 billion yen (~$300M USD) over five years to build this research hub in collaboration with Japanese materials and equipment companies.

Key points

• The lab develops core packaging technologies including wafer bonding, glass substrates, and new packaging architectures for low-power, high-performance AI chips
• Advanced packaging integrates GPUs, high-bandwidth memory (HBM), and accelerator chips into one package, directly affecting data transfer speed, power efficiency, and thermal performance in AI systems
• Samsung chose Yokohama for its proximity to Tokyo and concentration of materials suppliers, equipment makers, and research institutions
• The lab works separately from but collaborates with Samsung's domestic packaging research division
• Investment runs from 2024 through 2029, with plans to expand staff and scope to cover next-generation manufacturing processes

How to use it

• If building AI systems at scale, watch for Samsung's packaging innovations to enable more efficient multi-chip configurations with better thermals and bandwidth
• For infrastructure planning, advanced packaging developments will shape the performance and economics of next-generation GPU and HBM combinations
• Researchers working on large models should monitor how 3D packaging and substrate advances affect memory bandwidth and chip-to-chip latency in future hardware
