Abstract: A chemical-mechanical polishing process includes the steps of providing a semiconductor substrate having a first conductive line thereon, and then forming at least one dielectric layer over the substrate and the first conductive line. Next, a chemical-mechanical polishing method is used to polish the surface of the dielectric layer. Thereafter, a cap layer is formed over the polished dielectric layer. The method of forming the cap layer includes depositing silicon oxide using a chemical vapor deposition method with silicane (SiH4) or tetra-ethyl-ortho-silicate (TEOS) as the main reactive agent. Alternatively, the cap layer can be formed by depositing silicon nitride using a chemical vapor deposition method with silicane or silicon dichlorohydride (SiH2Cl2) as the main reactive agent. Finally, a via opening is formed through the dielectric layer and the cap layer, and a second conductive line that couples electrically with the first conductive line through the via opening.

Abstract: A manufacturing method of wafer passivation layer and manufacturing method of wafer bump. First, a wafer is provided with an active surface, which has a passivation layer and reveals a plurality of bonding pads on said passivation. Next, a redistribution layer is formed on the wafer and is electrically connected with the bonding pad. Further, a dielectric layer is formed on the wafer to cover the redistribution layer. Then, said dielectric layer is cured, followed by a patterning process, so that part of the redistribution layer can be revealed from the passivation. Next, plasma cleaning is performed on the active surface of the wafer, and the dielectric layer is cured again. Further, a bumping process is performed. This manufacturing method of wafer passivation and manufacturing method of wafer bump can effectively reduce potential damages of the passivation in further processing procedures and enhance yields.
