A flip-chip electrical coupling (100, 200, 300) is formed between first and second electrical components (110, 180; 410, 480). The coupling (100, 200, 300) includes a bump (240, 340) and a contact pad (315). The first electrical component (110, 210, 310, 410) includes the contact pad (315) electrically coupled to the first electrical component (110, 210, 310, 410) and a passivation layer (130, 230, 330) overlying the first electrical component (110, 210, 310, 410) and the contact pad (315). The passivation layer (130, 230, 330) is arranged having an opening (120, 220, 320) positioned over the contact pad (315). A bump (240, 340) is positioned overlying the opening (120, 220, 320) and substantially overlying the passivation layer (130, 230, 330). The bump (240, 340) is formed to be in electrical contact with the contact pad (315). The bump (240, 340) is arranged to couple the first and second electrical components (110, 180; 410, 480) during the flip-chip coupling process. |
