摘要:An integrated circuit and manufacturing method therefor is provided having asemiconductor substrate with a semiconductor device. A device dielectric layer is formed

on the semiconductor substrate. A first dielectric layer on the device dielectric layer hasan opening formed therein including a conductor reservoir volume. A barrier layer linesthe channel opening. A conductor core fills the opening over the barrier layer. A seconddielectric layer is formed on the first dielectric layer and has a second channel and viaopening provided therein. A barrier layer lines the second channel and via opening exceptover the first channel opening. A conductor core fills the second channel and via openingover the barrier layer and the first conductor core to form the second channel and via.The conductor reservoir volume provides a supply of conductor material to prevent theformation of voids in the first channel and in the via.
