Where I worked in the mid-1980's, I sometimes had to use an infrared microscope to take the temperatures of uncovered silicon transistor dice when they were dissipating as much as hundreds of watts, and at one point saw a transistor actually operating (ie, not just in storage or being soldered) at over 350 degrees C, which is 660 degrees F. Its life would have been very short operating at that temperature (unlike that of the ones in the link), but the heat did not suddenly destroy it. I tell people this when they're afraid of damaging an IC with heat by soldering.

Having the silicon carbide circuits they're talking about in the article will definitely help get the heat out without large heat sinks, and help survive high-temperature environments.

The fans on my macbook laptop kick in to overdrive if the cpu temp gets to around 85 degrees celsius and certain parts of the laptop are quite hot to touch. I could just imagine how hot the laptop would get if the cpu was allowed to go over 300 degrees celsius!

Further to what you were saying Garth, I have been working on a project which has undergone about three PCB revisions. the microcontroller I am using is surface mounted and each time I get a new PCB made up, I put the old assembled board in the reflow oven to desolder the microcontroller. I have done this numerous times and the microcontroller doesn't seem to mind :)
