Method of manufacturing semiconductor device

摘要

A method of manufacturing a semiconductor device includes: (a) forming an insulating layer having a contact hole on a semiconductor section in which an element is formed; (b) forming an electrode pad on the insulating layer so that a depression or a protrusion remains at a position at which the electrode pad overlaps the contact section; (c) forming a passivation film to have an opening on a first section of the electrode pad and to be positioned on a second section of the electrode pad; (d) forming a barrier layer on the electrode pad; and (e) forming a bump to be larger than the opening in the passivation film and to be partially positioned on the passivation film. The contact section is connected with the second section at a position within a range in which the contact section overlaps the bump while avoiding the first section of the electrode pad.
