editAre there substances that might make better tiny integrated circuit wires than cobalt?
editApparently cobalt is more conductive than copper at very small nodes. Sagittarian Milky Way (talk) 17:27, 26 August 2019 (UTC)
- There are other factors to consider. Gold is a decent choice, due to it's resistance to corrosion and ductility, which makes it easier to form and less likely to crack from vibrations. And the tiny amount used means that the cost isn't much of a factor. SinisterLefty (talk) 03:39, 27 August 2019 (UTC)
- However, if any of the gold touches silicon, it destroys the minority carrier lifetime, limiting its usefulness as a conductor.--Phil Holmes (talk) 08:26, 27 August 2019 (UTC)
