High Density Interconnect (HDI) with Glass Substrate for Next-Generation HPC
At 3DGS Inc., we enable breakthrough semiconductor packaging through High Density Interconnect (HDI) with glass substrate, delivering the performance, scalability, and reliability required for modern high-performance computing (HPC) systems.
As compute architectures evolve toward chiplet-based designs and heterogeneous integration, traditional substrates are reaching their limits. Our glass based interconnect technology provides a superior alternative, unlocking ultra-high density connectivity, improved signal integrity, and enhanced thermal performance.
Enabling High Density Interconnect (HDI) Using Glass Substrate
High Density Interconnect (HDI) using glass substrate represents a major advancement in semiconductor packaging. HDI technology uses ultra-fine lines, micro-vias, and multilayer routing to achieve significantly higher interconnect density compared to conventional PCB approaches.
When combined with glass substrates, HDI enables:
Fine-pitch interconnects for advanced chiplet integration
Increased I/O density for AI and HPC processors
Reduced signal path lengths for faster data transfer
Compact form factors for high-performance systems
Interposers play a critical role in this architecture. Acting as an intermediate layer between chips and substrates, they enable high-density interconnections and heterogeneous integration across logic, memory, and accelerators. This capability is essential for scaling performance in HPC environments.
The Role of Advanced Packaging for Chiplets
One of the key enablers of 3DHI is advanced packaging for chiplets. Instead of building a monolithic chip, systems are partitioned into smaller functional units, or chiplets, which are then integrated using advanced packaging techniques.
This modular approach provides several advantages:
Improved yield and reduced manufacturing costs
Greater design flexibility
Faster time to market
Scalability across multiple applications
By leveraging advanced packaging, 3DGS creates highly efficient systems that meet the growing demands of modern computing and electronics.
Why High Density Interconnects are Essential for HPC
High-performance computing systems, such as AI accelerators, GPUs, and data center processors, require massive data movement and ultra-fast communication between components.
HDI interposers support these needs by:
Providing thousands of interconnects within compact areas for high bandwidth
Enabling 2.5D and 3D integration, combining logic and high-bandwidth memory (HBM)
Reducing latency through shorter interconnect distances
Improving power delivery and signal integrity
Modern HPC packaging relies on interposer-based architectures to scale performance efficiently. These designs allow multiple dies to function as a single high-performance unit, with HDI enabling the dense routing required for such integration.
Glass Substrate for High Performance Computing (HPC)
A glass substrate for high performance computing (HPC) offers several advantages over traditional organic materials and silicon-based alternatives:
1. Superior Electrical Performance
Glass substrates exhibit low electrical loss and excellent signal integrity, making them ideal for high-frequency, high-speed applications such as AI and HPC. This minimizes signal degradation and improves overall system efficiency.
2. Enhanced Thermal Management
Glass substrates support effective heat dissipation, helping manage the increasing power density of modern processors and accelerators.
3. Dimensional Stability
With a low coefficient of thermal expansion (CTE), glass substrates maintain structural integrity under temperature variations. This stability is critical for maintaining alignment in high-density interconnect designs.
4. High Density Connectivity Using Glass Substrate
Glass provides ultra-flat surfaces that enable precise lithography and fine-line redistribution layers (RDL). This supports extremely dense interconnect routing and improved performance across large package sizes.
5. Improved Energy Efficiency
Glass based interconnect technology reduces capacitance and crosstalk, enabling faster communication speeds while lowering energy consumption which are key requirements for HPC workloads.
Advancing the Future of Glass Based Interconnect Technology
The semiconductor industry is rapidly transitioning toward advanced packaging solutions to sustain performance scaling beyond Moore’s Law. Glass substrates are at the forefront of this evolution, enabling:
Larger panel sizes for scalable manufacturing
Higher interconnect density than traditional organic substrates
Integration of diverse chiplets in a single package
Improved cost-performance balance for large-scale HPC systems
