Abstract
A method for manufacturing chip package includes the steps below. A wafer having an upper surface and a lower surface opposite thereto is provided, in which conductive bumps are disposed on the upper surface. The upper surface of the wafer is diced to form trenches. A first insulation layer exposing the conductive bumps is formed on the upper surface and in the trenches. A surface treatment layer is formed on the conductive bumps, and a top surface of the surface treatment layer is higher than that of the first insulation layer. The wafer is thinned from the lower surface toward the upper surface to expose the first insulation layer in the trenches. A second insulation layer is formed below the lower surface. The first and second insulation layers are diced along a center of each trench to form chip packages.
