@RobDinsmore: I assume you are commenting on Intel's trigate technology (monolithic 3D) but Intel has also done pioneering work on 3D stacked chips starting 2002! It is true the marketing folks get carried away with what is realistic with all these new technologies but I wouldn't lower that to the BS-level!
@daleste: I agree, it is a challenge to develop materials for joining substrates, providing thermal pathways matching the conductivities of Silicon but therein lies the problem. There aren't too many gap filling materials with particle sizes in the order of a few microns. There are some promises in some emerging nano-particle based adhesives that the printed electronics industry seems to be forging ahead with (3M has a good presence there).

Replay available now: A handful of emerging network technologies are competing to be the preferred wide-area connection for the Internet of Things. All claim lower costs and power use than cellular but none have wide deployment yet. Listen in as proponents of leading contenders make their case to be the metro or national IoT network of the future. Rick Merritt, EE Times Silicon Valley Bureau Chief, moderators this discussion.
