Abstract:
A method for manufacturing a semiconductor device includes an extra etching process. A bump or a UBM layer is etched additionally in the extra etching process after forming the semiconductor device such that the semiconductor device can conform to the standard of performance and appearance.

Claim (Index 1):
A method for manufacturing semiconductor device having bump structure, comprising the steps of:\n providing a substrate having a conducting pad and a protecting layer, the conducting pad is exposed by a through hole of the protecting layer; forming a UBM layer on the substrate, the UBM layer overlays the protecting layer and the conducting pad exposed by the through hole; forming a patterned photoresist layer on the UBM layer, an opening of the patterned photoresist layer exposes the UBM layer; forming a bump in the opening of the patterned photoresist layer, the bump is electrically connected to the UBM layer; stripping the patterned photoresist layer, a side wall of the bump and the UBM layer not overlaid by the bump are exposed; performing an etching process on the UBM layer, the UMB layer is etched for exposing the protecting layer by using the bump as a mask; and performing an extra etching process on the bump or the UBM layer, the extra etching process is used for adjusting a size of the bump, removing metallic residues or contaminates on the bump.
