Semiconductor Package Antenna Heat Dissipation Lateral Integration

The patent transitions from vertical stacking (z-dimension) to lateral integration (x-y plane) by placing the antenna and heat dissipation structure side-by-side on the same substrate layer. This dimensional reconfiguration allows both components to coexist without increasing package thickness, as they occupy different lateral spaces rather than stacking vertically.

The patent merges the antenna structure with the heat dissipation structure by integrating both functions into a unified lateral layout on the substrate. The antenna element and heat dissipation features share the same packaging plane, combining multiple functions within the same lateral footprint without requiring additional vertical space.

The patent applies different material properties to different regions: high thermal conductivity materials (copper or aluminum) are used specifically for heat dissipation structures where thermal management is critical, while the substrate and other components use materials with matched thermal expansion coefficients. This localized material selection optimizes heat dissipation in critical areas while minimizing thermal stress in other regions.

The patent employs composite material structures combining materials with different thermal properties. The heat dissipation structure uses high thermal conductivity materials (copper/aluminum) integrated with the substrate through intermediate layers or joint structures that accommodate thermal expansion differences, creating a composite system that achieves both heat dissipation performance and thermal stress resistance.
