The architecture can connect diverse interconnect types and chiplets from various process nodes, operating at different voltages. The base die may have state elements for drive. Functional blocks aboard the base die receive native signals from diverse chiplets, and communicate with all attached chiplets. The chiplets may share processing and memory resources of the base die. Routing blockages are minimal, improving signal quality and timing. The system can operate at dual or quad data rates.

Method of Fabricating High-Power Module

A method is provided to fabricate a high-power module. A non-touching needle is used to paste a slurry on a heat-dissipation substrate. The slurry comprises nano-silver particles and micron silver particles. The ratio of the two silver particles is 9:11:1. The slurry is pasted on the substrate to be heated up to a temperature kept holding. An integrated chip (IC) is put above the substrate to form a combined piece. A hot presser processes thermocompression to the combined piece to form a thermal-interface-material (TIM) layer with the IC and the substrate. After heat treatment, the TIM contains more than 99 percent of pure silver with only a small amount of organic matter. No volatile organic compounds would be generated after a long term of use. No intermetallic compounds would be generated while the stability under high temperature is obtained. Consequently, embrittlement owing to procedure temperature is dismissed.
