Patent ID: 6881654

Claim:
A solder bump structure and laser repair process for memory device, comprising: providing a semiconductor wafer, which comprises a substrate, an integrated circuit, and at least one bump pad and a plurality of fuses formed on the substrate and electrically connected with the integrated circuit; forming a first dielectric layer on a surface of the bump pad; performing an etching process to form a contact hole in the first dielectric layer and to expose a portion of the bump pad; forming a second dielectric layer on a surface of the semiconductor wafer outside of the contact hole; performing an under bump metallurgy (UBM) process so as to form a metal layer on a surface of the contact hole; forming a solder bump on the metal layer corresponding to the contact hole; performing a circuit probing process through the solder bump and a laser repair process to cut off portions of the fuses after the formation of the solder bump, the circuit probing process using a probing tip electrically connecting with the solder bump; and performing a connection process to complete connection of the semiconductor wafer and a packaging board.
