Emerging AI and deep-learning demands computing power that exceeds 10 kW to processors of cm2 footprint. At the IC level, interconnect densities will scale down to sub-micron pitch where the off-chip interconnect densities exceed Million I/Os per mm2. To cope up with the power, thermal solutions should reach resistances of <0.3 mm2 W/K. Advances in package integration are the key enablers for next-generation power delivery with higher power densities that exceed 5 A/mm2, efficiency and reliability. On the other hand, power electronics in the automotive world is diversifying to address various subsystem needs such as main and auxiliary inverters, DC-DC converters, on-board chargers and others, creating new challenges for meeting the density and reliability needs. This tutorial will focus on such key packaging building blocks: a)design for performance, manufacturing and reliability that relies on heterogeneous functional integration of wide bandgap devices, drivers, isolators and protection circuits to result in intelligent power modules, b) stacked or embedded packaging through direct plated interconnects onto die interfaces, c) thermal management through double-sided cooling with integrated fluidics, d)high-density passive components such as capacitors, transformers, inductors for integration in planar and 3D architectures. Specific emphasis will be on recent innovations and their origins in fundamental engineering sciences.
