Broadcom has begun shipping the industry's first 2 nm custom compute SoC built on its 3.5D eXtreme Dimension System in Package platform. The chipmaker's 3.5D XDSiP combines 2.5D techniques with 3D-IC integration using Face-to-Face technology, marking a significant advancement in semiconductor packaging.

This modular, multi-dimensional stacked die platform is designed to power next-generation XPUs for consumer AI applications. The technology enables unprecedented signal density, superior power efficiency, and low latency required for gigawatt-scale AI clusters. Broadcom's platform allows compute, memory, and network I/O to scale independently while maintaining a compact form factor.

The breakthrough positions Broadcom at the forefront of advanced semiconductor manufacturing, addressing the massive computational demands of modern AI infrastructure. By enabling high-efficiency, low-power computing at scale, this development could accelerate the deployment of more powerful and energy-efficient AI systems across data centers and edge computing applications.
