Abstract:
1. A semiconductor device comprising: a semiconductor chip; a wiring that is included in the semiconductor chip, the wiring having a first part and a second part joined at an intersection, the first part having a first width and a first length, the first width being shorter than the first length, the second part having a second width and a second length, the second width being shorter than the second length, the first width being different from the second width; a pad that is formed above the wiring and in a position overlapping the entire intersection; a second conductive material that is formed in a position between the intersection and the pad so as to cover the entire intersection, a first surface of the second conductive material facing the wiring, and at least three terminating edges of the second part of the wiring being within the second conductive material in plan view; a first conductive material being disposed between the pad and the wiring, and disposed within the second part of the wiring in plan view; and inorganic insulating layers that include a first inorganic insulating layer and a second inorganic insulating layer, the first inorganic insulating layer being formed between the wiring and the second conductive material, and the second insulating inorganic layer being formed between the second conductive material and the pad, wherein the second conductive material is made of a material other than resin and softer than the inorganic insulating layer.
