Filed: 2002-08-12
Abstract: <P>PROBLEM TO BE SOLVED: To prevent occurrence of a crack in a circuit formation region during dicing while preventing oxidation or corrosion of a seal ring having a copper layer on the uppermost layer.  <P>SOLUTION: A passivation film 120 forms an opening part 123 reaching up to an interlayer insulating film 109.
