发明名称 SEMICONDUCTOR DEVICE
摘要 The present disclosure provides a technique for improving the reliability of a semiconductor device where spreading of cracking that occurs at the time of dicing to a seal ring can be restricted even in a semiconductor device with a low-k film used as an interlayer insulating film. Dummy vias are formed in each layer on a dicing region side. The dummy vias are formed at the same intervals in a matrix as viewed in a top view. Even in the case where cracking occurs at the time of dicing, the cracking can be prevented from spreading to a seal ring by the dummy vias. As a result, resistance to moisture absorbed in a circuit formation region can be improved, and deterioration in reliability can be prevented.
