Abstract:
A process for producing a semiconductor device wherein a wiring pattern to be connected to an electrode of a semiconductor chip is formed on an insulating film formed on the semiconductor chip surface on which the electrode is formed, protruded electrodes are formed on the wiring pattern, the wiring pattern is covered with a protective film, and a bump for external connection is formed on the end portion of each of the protruded electrodes exposed from the protective film, the process comprising the steps of:covering the wiring pattern formed on the insulating film with a resist layer, and forming holes in the resist layer to expose part of the wiring pattern; plating the wiring pattern within the holes to form the protruded electrodes; removing the resist layer; effecting sealing by supplying a resin to the wiring pattern to form a resin layer having a top surface lower than that of the protruded electrodes, thereby forming a protective film; and forming the bump on each of the protruded electrodes in such a manner that the bump is bonded to the entire end face of each of the protruded electrodes.
