Abstract:
1. A semiconductor integrated circuit device comprising: a semiconductor substrate having a main surface such that a peripheral region of the main surface surrounds a circuit region of the main surface; a first insulating film formed over the main surface; external terminals formed over the first insulating film and arranged over the peripheral region; a first guard ring formed over the first insulating film and arranged as a frame in a plane along an outer periphery of the semiconductor substrate, the frame of the first guard ring being nearer the outer periphery of the semiconductor substrate than are the external terminals and being comprised of a same metal wiring layer as that of the external terminals; a second insulating film formed over the first insulating film and over the first guard ring and having openings exposing the external terminals, the second insulating film having a first portion formed over the circuit region and a second portion formed over the peripheral region such that the first portion and the second portion are formed separately and isolated from each other, and the second portion extending over the first guard ring; and bonding wires or bumps being in contact with the external terminals through the openings.
