Abstract
A conductive bump structure is formed on a substrate having a plurality of bonding pads and a first insulating layer thereon. The first insulating layer has a plurality of openings formed therein for exposing the bonding pads and a conductive post is formed on the bonding pads exposed through the openings. Therein, a gap is formed between the conductive post and the wall of the opening such that no contact occurs between the conductive post and the first insulating layer, thereby preventing delamination of the conductive bump structure caused by stresses concentrating on an interface of different materials as in the prior art.
