Abstract:
1. A semiconductor package comprising: an external electrode pad which is formed by a conducting member that is made either of conductive resin or conductive ink, said external electrode pad being connected to an internal circuit of a semiconductor device, said external electrode to be electrically connected to an external portion; a plating layer which is provided on an entire surface of said external electrode pad; and an insulating resin layer which covers said plating layer on a peripheral edge of said external electrode pad, said insulating resin layer exposing a portion of said plating layer on said external electrode pad, wherein the insulating resin layer is configured to decrease or prevent peeling from occurring at the conducting member of the external electrode pad and is configured to decrease or prevent cracking from occurring at the peripheral edge of the plating layer upon applying solder on the plating layer, the peeling and the cracking otherwise resulting from contractive forces due to cooling of the solder on the plating layer.
