You guys might want to take a look at this EETimes article from three years ago, before taking this announcement. http://www.eetimes.com/electronics-news/4077160/IBM-GIT-demo-3D-die-with-microchannel-cooling

Indeed, another example of how duct tape remains the ultimate engineering tool. Comments about the need for more information to understand this are certainly understandable. The nitty gritty details remain sketchy at this point. Presumably we will find out at least a little bit more once IBM and 3M make the announcement (which the WSJ report indicates will happen this week).

Sure... need more info to understand this... if implemented what are advantages over 3D transistor implementation??

Certainly, from server blade experience, we need to flow air or other fluid in between chip planes because stagnant medium will warm up which is inadequate for heat sinking. So I had thought they were heading in some microfluidic direction.

Need more technical information to understand the concept.

Many electrical engineers seem to have not passed thermodynamics. Heat conduction requires a temperature gradient. No such helpful gradient between stacked chips (especially in the middle).

LATEST ARCHIVED BROADCAST
Overview: Battle-hardened veterans of the electronics industry have heard of the “connected car” so often that they assume it’s a done deal. But do we really know what it takes to get a car connected and what its future entails? Join EE Times editor Junko Yoshida as she moderates a panel of movers and shakers in the connected car business. Executives from Cisco, Siemens and NXP will share ideas, plans and hopes for connected cars and their future. After the first 30 minutes of the radio show, our listeners will have the opportunity to ask questions via live online chat.
