Patent ID: 10910270

Abstract:
A manufacturing and packaging method for a semiconductor die is provided. The method prepares a wafer which has a seal-ring region, forms a first interlayer insulating film on the wafer, forms a metal wiring in the first interlayer insulating film, forms a second interlayer insulating film on the first interlayer insulating film, forms metal pads on the second interlayer insulating film, forms a passivation layer on the metal pads, removes a portion of the passivation layer in a region adjacent to the seal-ring region to expose the second interlayer insulating film, etches a portion of the second interlayer insulating film, forms a bump on the metal pads, removes the first interlayer insulating film and the second interlayer insulating film in the region adjacent to the seal-ring region by a laser grooving process, and dices the wafer into a first semiconductor die and a second semiconductor die.
