A manufacturing method of a semiconductor package includes locating, on a substrate, a semiconductor device having an external terminal provided on a top surface thereof, forming a resin insulating layer covering the semiconductor device, forming an opening, exposing the external terminal, in the resin insulating layer, performing plasma treatment on a bottom surface of the opening, performing chemical treatment on the bottom surface of the opening after the plasma treatment, and forming a conductive body to be connected with the external terminal exposed in the opening.

A solder connection may be surrounded by a solder locking layer (1210, 2210) and may be recessed in a hole (1230) in that layer. The recess may be obtained by evaporating a vaporizable portion (1250) of the solder connection. Other features are also provided.

A method includes forming a seed layer on a semiconductor wafer, coating a photo resist on the seed layer, performing a photo lithography process to expose the photo resist, and developing the photo resist to form an opening in the photo resist. The seed layer is exposed, and the opening includes a first opening of a metal pad and a second opening of a metal line connected to the first opening. At a joining point of the first opening and the second opening, a third opening of a metal patch is formed, so that all angles of the opening and adjacent to the first opening are greater than 90 degrees. The method further includes plating the metal pad, the metal line, and the metal patch in the opening in the photo resist, removing the photo resist, and etching the seed layer to leave the metal pad, the metal line and the metal patch.

A semiconductor device includes a die having a pad, a passivation disposed aver the die and a portion of the pad, a polymer disposed over the passivation, a molding surrounding the die and the polymer, and an interface between the polymer and the molding. The interface and the passivation define an angle less than or greater than approximately 90.
