摘要:
Disclosed is a process of making a semiconductor device wherein an insulation layer has a copper plug in contact with the last wiring layer of the device. There may also be a barrier layer separating the copper plug from the insulation layer. There may also be a cap layer over the copper plug to protect it from oxidation. There may also be a dielectric layer over the cap layer.
