Copper has one third the resistivity of Aluminum and can be electrodeposited easily. Hence, Copper can be used for chip wiring. This Nanofablicaton technology is used to electrodeposit Copper into the fine cavities or vias of diameters less than 0.1mim, and lengths 1/1000 of the diameter of human hair. Since then the Copper Damascene on chip semiconductor wiring process has spread out to semiconductor industries all over the world and branched into four major industrial applications: Damascene, through silicon via, interstitial via hole build-up printed wiring boards and Copper foil that is sm...
