Abstract:
A bump fabrication process is provided. A substrate having a plurality of openings of various widths thereon is provided. The substrate is dipped into an electrolytic solution. A step current that increases gradually is provided to the solution to perform an electroplating operation so that the conductive material is deposited inside the openings to form bumps with uniform thickness.
