News Cubic Boron Arsenide Promises 10x Better Heat Dissipation for Chips

[Admin]

Researchers may have just discovered the best semiconductor material in existence: cubic boron arsenide. The compound promises 10x better heat dissipation compared to silicon, while also having a much better flow for positively-charged particles known as holes.

"Cubic boron nitride is here with lower temperatures...."

I want to CNC a new IHS for my CPU along with Heat-Pipe Fan units using this Cubic Boron Arsenide.

It’s not just the thermal conductivity of the bulk semiconductor material, but also at the interface to heat sink or spreader. An oxide layer always forms on exposed metal. Special techniques are necessary to remove the oxide layer and bonding to the heat sink.
also , isotopically pure Si 28 has much better thermal conductivity than natural. A company tried this 20years ago

I like this article, it's well written. I can understand all the science parts even though this isn't a field I'm familiar with.

This piece made me hyped for a technology that probably wouldn't even arrive in my lifetime.

Kudos to the writer.

Better thermal performance is nice, but how is the wallet performance? I doubt very many buyers will be interested in chips with 3X better junction-case thermal resistance (the substrate's 1200W/mK still dumps into copper or whatever the case is made of at 400W/mK or worse) if the chips cost 10X as much to make for the same electrical or compute power.
