Abstract: A routing structure and a method of a wafer substrate with standard integration zone for integration on-wafer, which comprises a core voltage network, an interconnection signal network, a clock signal network and a ground network, wherein the core voltage network and the interconnection signal network belong to a top metal layer, the clock signal network is located in a inner metal layer, and the ground network is located in a bottom metal layer. The pins provided on the standard zone include core voltage pins, interconnection signal pins, clock signal pins, ground pins, and complex function pins. The complex function pins are directly connected to the outside of the system by TSV at the bottom of the wafer, and the other pins are connected by their signal networks. The present disclosure solves the yield problem with few metal layers of the wafer substrate for SoW.

Abstract: The present disclosure discloses a three-dimensional stacked package structure with a micro-channel heat dissipation structure and a packaging method thereof. The three-dimensional stacked package structure includes a chip package portion comprising a multi-layered structure with stacked chips, wherein the stacked chips are provided with through silicon vias and packaged in a three-dimensional stacked packaging manner and a silicon substrate package portion comprising a silicon substrate. The silicon substrate is provided with micro bumps which are to be interconnected with external lead wires. The chip package portion is assembled on the silicon substrate by bonding with the micro bumps. The stacked chips are etched with micro-channels and through holes corresponding to each other. The micro-channels are for coolant flowing in a horizontal direction, and the through holes are for coolant flowing in upper and lower layers. Sealing rings are arranged around the micro-channels and the through holes.
