Broadcom, a leader in semiconductor innovation, has unveiled a revolutionary technology aimed at accelerating chip performance. This groundbreaking development comes at a critical time, as the demand for artificial intelligence (AI) solutions continues to surge across industries. Broadcom’s latest advancement, known as the 3.5D eXtreme Dimension System in Package (XDSiP), introduces a new level of efficiency and power in semiconductor design.
What is XDSiP Technology?
Broadcom’s 3.5D XDSiP technology is a cutting-edge approach that utilizes a unique “Face-to-Face” (F2F) chip arrangement. This method stacks the crystals on the chip with their front sides aligned, creating a seamless and efficient connection. With this innovative design, Broadcom achieves the following:
- Increased Chip Area: The technology allows for crystals with a combined area exceeding 6000 mm² to be placed on a single substrate.
- Enhanced Memory Integration: Up to 12 HBM (High Bandwidth Memory) stacks can be incorporated into one chip package.
- Improved Energy Efficiency: The F2F stacking reduces electrical interference, enhancing energy performance.
Benefits of Broadcom’s F2F Stacking Technology
The F2F stacking design provides several key advantages, particularly for AI-driven applications:
- Performance Boost: The direct connection between the top metal layers of the stacked chips ensures superior performance and reliability.
- Energy Optimization: Minimal electrical interference and high mechanical strength result in improved energy efficiency.
- Increased Memory Capacity: The ability to integrate multiple HBM stacks in a single package opens up possibilities for more complex AI computations.
This innovation marks a significant leap forward in chip technology, offering enhanced capabilities for powering next-generation AI systems.
Collaboration with TSMC for Production
The Taiwanese semiconductor giant TSMC has been entrusted with manufacturing Broadcom’s chips utilizing the new XDSiP technology. TSMC, known for its state-of-the-art fabrication processes, is expected to ensure the production of high-quality chips. Currently, five products featuring this technology are under development, with initial deliveries planned for February 2026.
