Patent number: 7091121Abstract: A bumping process mainly comprises the following steps. Initially, a wafer having a plurality of bonding pads and a passivation layer, which exposes the bonding pads, is provided. Next, a first dielectric layer is disposed on the wafer so as to form a plurality of first openings and second openings. The first openings and the second openings expose the bonding pads and the passivation layer respectively. Afterward, a patterned first electrically conductive layer is formed on the first dielectric layer, the bonding pads and the passivation layer exposed out of the first dielectric layer through the second openings. Then, a second patterned conductive layer is formed directly on the first patterned conductive layer.Type: GrantFiled: January 9, 2004Date of Patent: August 15, 2006Assignee: Advanced Semiconductor Engineering, Inc.Inventor: Ching-Fu Horng
