Abstract: Some embodiments relate to a semiconductor device package, which includes a substrate with a contact pad. A non-solder ball is coupled to the contact pad at a contact pad interface surface. A layer of solder is disposed over an outer surface of the non-solder ball, and has an inner surface and an outer surface which are generally concentric with the outer surface of the non-solder ball. An intermediate layer separates the non-solder ball and the layer of solder. The intermediate layer is distinct in composition from both the non-solder ball and the layer of solder. Sidewalls of the layer of solder are curved or sphere-like and terminate at a planar surface, which is disposed at a maximum height of the layer of solder as measured from the contact pad interface surface.

Abstract: A method of forming an integrated circuit structure includes forming a patterned passivation layer over a metal pad, with a top surface of the metal pad revealed through a first opening in the patterned passivation layer, and applying a polymer layer over the patterned passivation layer. The polymer layer is substantially free from N-Methyl-2-pyrrolidone (NMP), and comprises aliphatic amide as a solvent. The method further includes performing a light-exposure process on the polymer layer, performing a development process on the polymer layer to form a second opening in the polymer layer, wherein the top surface of the metal pad is revealed to the second opening, baking the polymer, and forming a conductive region having a via portion extending into the second opening.
