Which metal used in processor

[sarvan_15]

Hello,I need which type of metal or alloy used in processor and computer storage elements

Aluminum, copper, not sure about gold, some poor people on ebay seem to get gold from CPU pins to get money even though the CPU will get you more money, solder...

Inside a CPU there is VERY fine connecting wires made from gold. The gold is used to enhance the conductivity of the part.

Traces within the IC are copper. Solder balls between the CPU die and substrate are likely low-temperature eutectic alloys like Tin-Bismuth. Traces on the substrate are copper. The plating on pins/pads and most other connections other than power is usually gold but cheap non-critical connectors may be tin-plated.

Gold is rarely used inside ICs since it has worse conductivity than copper and is horribly more expensive. Silver has the highest room-temperature conductivity among pure metals.

Aluminum was used inside ICs until ~1999 due to being one of the easiest metals to work with but it was becoming a performance bottleneck due to relatively low conductivity which is why research into ways of preventing copper from diffusing or oxidizing during IC processing and operation became a major focus. After Intel and IBM figured out how to use copper on silicon, copper quickly became the most commonly used metal in mass-produced VLSI ICs and still is to this day.

Since silver is much more expensive than copper, I doubt we will see silver used in mass-produced ICs. The performance gains are unlikely to justify the 50X more expensive metal and massive R&D investments.

Isn't the IHS made out of aluminum or copper or something?

The way the question was asked, I'm guessing the OP is mainly interested in the types of metals used for the electrical components rather than decorative/dissipative add-ons.

Hi

Lol...Homework again...

All the best Brett

^ Heh, think you're right. Kidz don't wanna do their own homework anymore.

OP: The Lone Ranger only uses silver CPUs in his computers.
