Bridge Package Layout for Thin High-Density Interconnects

The patent transitions from planar interconnection to three-dimensional vertical stacking, placing integrated devices at different heights and connecting them through vertical vias and conductive structures. This dimensional change enables high-density interconnections within a reduced footprint and thickness, resolving the contradiction between compact size and reliable electrical connections

The patent implements nested metallization structures where conductive layers, vias, and interconnects are embedded within dielectric layers in multiple stacked levels. This nesting approach allows extensive interconnections to be contained within the vertical profile of the package, achieving high connection density without increasing the package footprint or compromising reliability

The patent divides the interconnection system into discrete functional layers including separate dielectric layers, conductive layers, and via structures. Each layer performs a specific function (signal transmission, power distribution, or inter-layer connection), which simplifies the manufacturing process by allowing standardized fabrication techniques to be applied to each segment rather than treating the entire complex structure as a single unit

The patent employs universal metallization structures that serve multiple functions: conductive interconnects provide both signal transmission and electrical connection, while dielectric layers simultaneously provide electrical isolation and mechanical support. This multi-functionality reduces the number of specialized components needed, thereby simplifying manufacturing while maintaining high-density interconnections for improved data processing performance
