Abstract:
1. An electronic module, comprising: a first carrier substrate; a second carrier substrate formed of silicon, which is bonded to the first carrier substrate; a high performance processor chip and a plurality of memory chips which have different thicknesses from each other are flip-chip bonded to the second carrier substrate, wherein the high performance processor chip, having a higher power density than the memory chips, is mounted in a center region of the second carrier substrate, wherein the memory chips are mounted along peripheral regions of the second carrier substrate; a microchannel cooling device formed of silicon, wherein the memory chips and the high performance chips are rigidly bonded to the microchannel cooling device via rigid thermal bonds and wherein the high density power chip has a lower total thermal resistance in the thermal bond between the high density power chip and the microchannel cooler device to maintain a same maximum junction temperature as compared to the memory chips, the microchannel cooling device comprising: a microchannel plate and a manifold plate connected to each other via a bonding material, the microchannel plate comprising: a plurality of microfins that define a plurality of microchannels which are formed in surface regions of the microchannel plate that are aligned with the high performance processor chip and the plurality of memory chips, the manifold plate comprising: a plurality of fluid manifolds formed therein, wherein each fluid manifold comprises a corresponding manifold channel formed in a surface of the manifold plate and a corresponding pattern of fluid vias that form openings which extend from an opposing surface of the manifold plate to various points along the corresponding manifold channel, and wherein the fluid vias for a given manifold channel are formed as a series of openings arranged in a zig-zag pattern and wherein the manifold channel includes: tapered channel segments formed between the openings on a surface of the manifold plate that faces the microchannels.
