WebA method for manufacturing gold bumps including providing a substrate including a protective layer, which exposes at least a bonding pad, on a surface, covering a photo resist on the surface of the substrate, performing a photolithography process to pattern the photo resist for exposing a portion of the protective layer and the bonding pad, removing a … Gold-ball bumping can be a one-step process, but can involve two steps if a coining process is needed to planarize the ball bumps. Once the die is completely bumped, it is flipped and attached to the substrate, providing the first-level interconnect as well as protection for the active die surface. See more Wafer bumping involves putting a conductive material on each die pad on a wafer to attach it to a package or circuit board forming the first-level interconnect. Bumping has gained popularity due to demand for reduced … See more Temperature is a concern when selecting the method used to attach the gold bumped die to the substrate. A thermosonic … See more Coplanarity is a paramount factor in gold bumping for flip chips. To be coplanar, all points must lie on the same geometric plane. In flip chip … See more A benefit of bumping is reduced interconnect length. A typical wire length might be 30-mil long, whereas a typical bump connection might be only 2-mil long. This shorter … See more

Websalt for gold bump formation were evaluated by dc plating. In this study, phosphorus acid, phosphoric acid, sulfuric acid, and boric acid were evaluated as the conductive salts. Appearances of pho-toresist and gold bumps after gold electroplating are shown in Fig. 2. The smooth gold deposition was obtained by using 0.05-0.15 mol/L phosphorus acid.
