Diamond Thermal Conductivity: A New Era in Chip Cooling

https://spectrum.ieee.org/diamond-thermal-conductivity
78•rbanffy•3mo ago

Comments

0cf8612b2e1e•3mo ago
Have diamonds found their way into other industrial cooling solutions? With the research into gem grade diamonds, I have been expecting cheap ugly synthetic diamonds to be used in more products. I have long joked that I want a diamond frying pan.
rbanffy•3mo ago
> I have long joked that I want a diamond frying pan

As long as you don’t use it on a gas stove, you should be fine.

kees99•3mo ago
Why? Diamond has very low thermal expansion, so no risk of stress/embrittlement/cracks from uneven heating.

Or you mean it'll catch fire? Also not a concern. That is supposed to happen at a temperature well above anything useful for cooking.

LtdJorge•3mo ago
I think because it will burn your hand?
rbanffy•3mo ago
It’s safe to assume the handle is made from something else.
IAmBroom•3mo ago

rbanffy•3mo ago
The temperature of the blue flame on a stove should be above 1000 Celsius, well above what’s required to oxidise diamonds. They won’t catch fire, but your diamond pan will erode. Once you remove it from the flame, it won’t continue “burning”.

Should be safe on electrical stoves though.

kees99•3mo ago
Would that >1000°C reach the surface though?

There are some heady boundary-layer effects and temperature/temp-conductivity gradient physics involved here. For simplicity sake, consider a plastic [1] bag full to the brim with water, held over open flame. Will bag melt (oxidize, erode)?

[1] polyethylene melts around 120-ish °C and ignites around 220-350 °C (sources vary)

galangalalgol•3mo ago
Someone sells a diamond coated pan https://bluediamondshopping.com/
mjevans•3mo ago
It's probably fine on the inside?
IAmBroom•3mo ago
Why are you using a question mark.
mjevans•3mo ago
The material would be 'fine', but I'm not sure how safe or effective it would be as I'm not a materials expert. Just considering the risk of the material. (Yeah, the material would be fine, is it safe and beneficial? That part of 'fine' I can't define.)
rbanffy•3mo ago
That's a good point. Have you done the experiment?
PunchyHamster•3mo ago
Just put them on inside only
rbanffy•3mo ago
But wasn't the point that diamond is a great hear conductor?
IAmBroom•3mo ago
It would still work, if the bottom cladding were very thin, and a decent conductor.
Atomic_Torrfisk•3mo ago
> ugly synthetic diamonds

Not any more, their quality has increased recently. Not that I care, wife and I did without them during our engagement.

jrk•3mo ago
I think the point was not that gem-grade synthetic diamonds are ugly, but that, as industry masters gem-grade production, presumably below-gem-grade production (“ugly synthetic diamonds”) would become cheap enough to deploy in more engineering settings where diamond’s other unique properties were the key concern.
Yossarrian22•3mo ago
I’m surprised nobody has done a phone screen yet
Tuna-Fish•3mo ago
Large single crystal diamond, what is required for a nice transparent screen, is still quite expensive. This article is about polycrystalline diamond, which is not really that transparent, but is nearly as good at thermal conduction as monocrystalline diamond.
akshatjiwan•3mo ago
Your comment reminds me of apple's attempt to make sapphire screens. That didn't turn out so well.

https://www.theguardian.com/technology/2014/feb/10/sapphire-...

addaon•3mo ago
Apple still uses sapphire screens on the nicer watches.
KiwiJohnno•3mo ago
I have a Garmin with a sapphire screen. I've worn it every day for over 5 years, working on cars, in the garden, snorkelling on coral reefs.

In short, I my watch has NOT had an easy life. I've made no attempt to protect it or taken it off for anything except charging. There is barely a mark on the screen. A sapphire screen will be a hard requirement for my next watch.

cassianoleal•3mo ago
I wear mine while rock climbing. The watch has been put through a lot of beating against all kinds of rock. I've already chewed through 3 straps on this watch. The titanium case is lightly scratched, but the screen is absolutely pristine!

This is my second sapphire Garmin, and it's absolutely worth the premium.

IAmBroom•3mo ago
> I've already chewed through 3 straps on this watch.

Ever consider carrying a protein bar or two?

cassianoleal•3mo ago
:)
rowanG077•3mo ago
Even if that were cheap I don't think diamond would excel in this use case. It's of course extremely hard but I'd expect that it would be extremely prone to cracking. In addition the high index of refraction would make the diamond screen very reflective and you would need some fancy coating which of course wouldn't be as strong as diamond.
IAmBroom•3mo ago
I don't know why you expect it would be prone to cracking, but it isn't - or else a wedding ring would have a life expectancy shorter than the average marriage.

As for a reflective screen, the term for that is "shiny", and could be marketed as desirable - it signals that the owner has an expensive watch. It wouldn't interfere with use, unless the user was wearing a bright headlamp.

gpm•3mo ago
3D printer nozzles, which is sort of the opposite (industrial heating products).

Part of the argument is that better heat conduction means that you can run the nozzle cooler resulting in less heat conduction to the cold side (above where you want the filament to melt) so I guess its "cooling" in a sense too.

snalty•3mo ago
This reminded me of this: https://www.innovationcooling.com/products/ic-diamond/?srslt... which seemed to be all the rage in PC building 10 years ago

lightedman•3mo ago
Nothing new, Applied Diamond has made this stuff for several years and it is incredible. Imagine putting a 15w LED on a typical 20mm star board made of diamond - you do not need a heat sink. Just minor air flow over the package is enough.

A little unlike IEEE to be nearly half a decade out of the loop.

yorwba•3mo ago
The new thing here is growing a thin layer of diamond directly on top of a chip.
trhway•3mo ago
naturally, graphite has similarly high thermal conductivity along the layer direction (which is basically graphene), and one would think that there should be some way to put such a thin layer of graphite/graphene on top (or inside) the chip to achieve similar results.
gpm•3mo ago
Would the electrical conductivity be an issue?
IAmBroom•3mo ago
On a printed circuit? Nah. Can't imagine why it would.
Tuna-Fish•3mo ago
The invention is a fast, low-temperature deposition process, which can then be used directly on a semiconductor device.
lateforwork•3mo ago
Diamond Foundry achieves the same end goal even if the deposition methods and technical processes may differ: https://df.com
Tuna-Fish•3mo ago
They produce the diamond wafers separately and then later bond them, a process that is dramatically more expensive and results in a worse bond.
akshatjiwan•3mo ago
I think what they have grown diamond on the transistor which then bonds to the substrate through a SIC interlayer.

From what I understand their idea seems to be that since most heating occurs at channels they act like hotspots and therefore it would be much better to drain away heat from them directly.

This is different from creating transistors on a diamond substrate.

lateforwork•3mo ago
> But my research group at Stanford University has managed what seemed impossible.

Wait a minute, others have been doing this already: https://www.df.com/

How is this different?

mutagenesis•3mo ago
What you linked is bonding a diamond substrate to the back of your IC. What's in the post is growing diamond lattice/features directly on your wafer. With the new way, you can get diamond closer to your heat sources, increase contact area, etc.

No idea if it actually matters. Is this a single digit percentage increase in thermal conductivity by messing with a finicky, temperamental process? I don't know. What the paper writers are proposing is under the limit of when transistor structures break down, but not by much.

IAmBroom•3mo ago
They mention getting 10's of degrees Celsius improvement. It's very significant.
