Patent ID: 7382057

Claim:
A surface structure of a flip chip substrate comprising: a substrate defined as a chip conductive zone and a passive component conductive zone; a plurality of first conductive pads formed on the chip conductive zone; at least a second conductive pad formed the passive component conductive zone; a first insulating layer covering the chip conductive zone of the substrate and the first conductive pads, the first insulating layer having first patterned openings, the top-surface of the first conductive pads expose to the first patterned openings; and a second insulating layer covering the passive component conductive zone of the substrate and the second conductive pads, the second insulating layer having a second patterned opening, the top-surface of the second conductive pad expose to the second opening, wherein a thickness of the first insulating layer is greater than that of the second insulating layer and the first insulating layer does not cover the second insulating layer.
