This is a very odd question. I am currently doing a chemistry project that is set to be completed in January of 2004. I am trying to find an emement, chemical, substance, alloy, etc. that conducts electricity BETTER than the products used in the AMD Barton Core. I have turned the internet upside down looking for something that will tell me what is in the Barton Core ... I have come up with nothing. So if anyone knows what it is made out of, or what kinds of metals and alloys it uses, a responce would be gold to me! Thanks!
Silver is the best electrical conductor IIRC.
With copper close behind.
(thus the use of copper interconnects)
It also helps to use istopically purse silicon too.
Of course if you want perfect conductivity chill certain metals down to less than 4 Kelvin and get some superconductivity happening.
Course CPu's dont work down there... CPU's ned some resistance to function :smile:

The other material besides the metal (silver or copper) and silicon is whatever advanced material they are using for an insulator right now. Better insulation mean higher speeds, because you can make the whole thing smaller. I would look for the best insulator that can be spread as thin as possible.
have you tried asking AMD. just tell them you have no interest in how the inards of the chip work you want to know what condutive material they use. alternativley try asking folk at MIT, Intel, maybe even the Graphics chip manufactureres. cant hurt to try.

The AMD Barton core is just the name AMD gave to their newest CPU. The materials used in it are exactly the same as in many other chips (this is not exactly true as there are more chip-technologies, but true enough for now).
A chip is made of chemically almost pure mono-crystalline silicium. 'Almost' is the key word here: silicon is a *semi* conductor which means that it conducts very poorly compared to real conductors (like copper, gold), but it conducts very well compared to insulators (like plastics, ceramics and silicon-oxide). Pure silicon is a very poor conductor, but you can make it to conduct much better by polluting it with small quantities (very small, much less than 1 percent) of other elements. Still many materials (especially metals and alloys) conduct far better than silicium.
The chip-production process involves polluting the silicium crystal at exactly the right spots, oxidizing it at other spots where you need an insulator, or putting a metal on it where you need a conductor. (I believe the metal used mostly is aluminum) The process of putting all these materials on the right spots is called photolitography. Actually only one side of the chip is being processed.
Now this chip is glued onto a substrate (this could be anything: glass, ceramics, plastics, metal), epoxy-resin in the case of the Barton CPU. This substrate contains the metal pins which connects the chip to the outside world. In earlier days the chip was then connected to the pins by welding very thin golden threads from the pins to the chip; nowadays the chip is placed directly on a contact-area where tiny metal balls provide the contact between chip and contact area.
Now an answer for your question:
any superconductor will conduct better than a barton core.
most metals and alloys will conduct better than the silicium used in the barton core.
Any conductor or semi conductor will conduct better than silicium-oxide.
Aluminum (used in the chip as conductor) will be outperformed by copper, which will be outperformed by silver, which will be outperformed by gold.
As for the pins: these are made of a very good conductor, sometimes alloys, or gold-plated to avoid oxidation.
You may check the "Handbook of Chemistry and Phyisics" for the exact conductivity of these materials.
Silver first place
Copper second place
Gold third place
Gold conduct better than any other metal besides silver or copper. Gold does not corrode also. That is why it is used for contacts often. Silver and copper corrode. Copper is way cheaper than silver or gold and is used mostly.
The thing that <i>I</i> find interesting is that, after re-reading them, I found the two links I posted above (which few people bothered to read, evidently) actually disagree about the exact "rankings". Both sites rank silver first and copper second.
