need high-rez pic of silicon die

[Sage]

I need a high-rez pic of a silicon die. well, not really high-rez, but a lot more than the tiny things you find laying around most of the internet. I don't care of it's CPU, GPU, or any-other-PU.

either that or someone give me an idea of how to make a MRay or PRMan material to look like it and I can just render the thing.

The biggest ones I found with a quick search:

• http://www.theinquirer.net/images/articles/ppc970.jpg - 1517x2100 pixels, not annotated at all.
• http://www.chip-architect.net/news/Northwood_130nm_die_text_3200x2400.jpg - heavily annotated.

If you want bigger/more detailed than that, you might try asking people that design chips, as they sometimes keep around gigantic posters of their designs - although I cannot help you there.

thanks, those are pretty nice... but what I'm really looking for is like what the naked eye is able to see if you pp the cooler off and look at it. I happen to think they are pretty beautiful, and perfect for the logo.

Something like this? http://www.tbreak.com/forums/attachment.php?attachmentid=7542 (an Athlon64 with its heat-spreader removed).

yeah that's great, but if only it were front-on so that you could see the prettiness of all it's little refleties and rainbows

I suspect that's NOT what you want, though. What makes a bare die so fascinating to watch is, I suspect, very much the fact that it looks as if it has different colors when viewed from different directions, even to the extent that your two eyes will perceive different colors due to the angle difference, but still have a color difference that doesn't match what you get with plain metallic surfaces. This effect is very hard to capture with a camera - I have seen people trying to film a bare die with a $70K camera, and the result had absolutely none of the lustre of the die being filmed.

well dang. do you know what it is about the die's physical properties that makes it look that way? These little things certainly are fascinating.

One can guess at properties of silicon as a material, or the way the silicon wafers are cut from a silicon crystal, or any post-processing steps performed on the die as part of packaging, but to be honest: I don't really know. It certainly doesn't look like traditional diffuse/specular lighting though.

hmm.. I'm thinking that when we look at then "with the naked eye" we are actually looking at the ones mounted, and so they have that blue-ish-grey-ish stuff on them which dulls the effect that is seen in all of the pretty pictures such as

Here's a peeled off wirebond package.

hmm.. thanks... it has become apparent that I'm just going to have to either have some weasel of a freelance artist make me a logo or just mess around myself and see if I can get the effect I'm looking for out of Maya.
