Stacked Embedded Capacitors Wiring Board

The patent divides the capacitor access system into independent segments by providing separate access channels for each capacitor in the stack. Each capacitor has its own pair of access holes and conductive vias, allowing independent electrical connection without requiring all capacitors to be accessed through a common path. This segmentation resolves the contradiction by maintaining high capacitance quantity while restoring individual accessibility and circuit design flexibility.

The patent transitions from a planar capacitor arrangement to a three-dimensional stacked configuration with vertical access channels. By utilizing the vertical dimension for capacitor stacking while maintaining horizontal access paths through the substrate, the design achieves increased capacitance density without sacrificing electrical accessibility. The conductive vias extend through the substrate thickness to connect to capacitor electrodes, creating multi-dimensional interconnection pathways.

The patent embeds multiple capacitor layers within a single substrate structure, creating a nested configuration where capacitors are stacked vertically within the same footprint. The substrate contains multiple layers of conductive patterns and insulating materials that simultaneously support multiple capacitor assemblies. This nesting approach increases capacitance quantity while maintaining a unified manufacturing process and simple external appearance.

The patent merges multiple capacitor functions into a single integrated substrate structure. The substrate simultaneously serves as the mechanical support, electrical interconnection medium, and insulation barrier for multiple capacitors. By combining the functions of substrate, capacitor holder, and electrical connection path into one integrated component, the design achieves high capacitance density without proportionally increasing manufacturing complexity.

The patent resolves the space conflict by transitioning from two-dimensional planar capacitor placement to three-dimensional vertical stacking. Multiple capacitors are arranged in the vertical dimension within the same footprint area, achieving high decoupling capacitance density near the microprocessor without increasing the planar circuit density. The vertical stacking allows proximity to the processor while maintaining manageable circuit routing.

The patent nests multiple capacitors within a compact vertical structure directly adjacent to the microprocessor. The nested capacitor arrangement allows maximum proximity to the processor core while minimizing the overall footprint. This nesting approach provides effective decoupling capacitance in the limited space available near the processor without requiring extensive planar routing.
