description | Compliant electrically connection bumps for an adhesive flip chip integrated circuit device and various methods for forming the bumps include the steps of forming polymer bumps on a substrate or an integrated circuit die and coating the polymer bumps with a metallization layer. The polymer bump forming step includes the steps of coating a polymer material on a substrate, curing the polymer and the etching the bump pattern from the polymer material. The overcoating step includes electrolessly plating a ductile metal such as gold on the polymer bump. |
