Glass-Core Wireless Interconnects for High-Frequency IC Packaging

The patent employs composite materials by integrating glass cores with metal interconnect structures within the package substrate. The glass core provides low-loss dielectric properties for high-frequency signals, while metal interconnects provide high-conductivity pathways. This composite approach combines the advantages of different materials to simultaneously achieve good signal integrity at high frequencies and manufacturability through established glass substrate processing techniques.

The patent replaces traditional mechanical physical wiring with electromagnetic field-based wireless communication channels. By substituting physical conductors with electromagnetic wave propagation through the glass core, the system achieves greater routing flexibility and bandwidth without being constrained by physical wire layouts, while maintaining manageable device complexity through integrated antenna structures.

The patent utilizes parameter changes by optimizing the dielectric constant and loss tangent of the glass core material to enhance bandwidth performance. By carefully selecting and controlling material parameters such as glass composition, density, and thermal properties, the system achieves high bandwidth while maintaining compatibility with standard manufacturing processes and tolerances.
