Copper interconnect
(重定向自Copper chip)
Copper-based chips are semiconductor integrated circuits which use copper for interconnections in the metalization layer, the BEOL. Since copper is a better conductor than aluminium, chips using this technology can have smaller metal components, and use less energy to pass electricity through them. Together, these effects lead to higher-performance processors. They were first introduced by IBM, with assistance from Motorola, in 1997.
