Fujitsu Develops Technology for High-Reliability Gallium Nitride HEMT

Nice. Check out the Arrhenius plot, though...they're extrapolating from about a week's worth of data at 300C. Not the most persuasive data, even by the dubious standards of accelerated aging. They might turn out to be tasty to mice, for instance which of course would produce very large 1/f noise. ;) (This actually happened with undersea cables and sharks, about 20 years ago.)

They do the same with DVDs and claim your data will be safe for 100 years.... :-)

That's great news. We blew up almost $1000 worth of Nitronex GaN fets in two days.

Great news that it will be a while before you can blow up some of these, or great news that they're being developed?

Both!

John

John, you brute, you're the stuff FETs--in their worst moments--dream of. You *are* the thing which--for them--goes bump in the night!

My hat's off to you sir.

Fets nshould be like wine, "We shall sell no fets before their time", which Nitronex sure did. GaN on silicon had/has a huge defect density.

My engineer who was working with these things, "samples" at $125 each, told me he'd blown up four that morning. "Want too see?" he asked me.

I was wondering, "What's a HEMT?" so to not appear the ignoramus I put it into google, and got this:

It's very comprehensive, but can any of you gurun tell me if it's accurate? :-)
