Abstract
A method of manufacturing chip package is disclosed. The method includes steps of providing a wafer with an upper surface and a lower surface opposite thereto, in which a plurality of conductive pads are disposed on the upper surface; forming a plurality of conductive bumps on the corresponding conductive pads; thinning the wafer from the lower surface towards the upper surface; forming an insulating layer under the lower surface; etching the upper surface of the wafer to form a plurality of trenches exposing the insulating layer; forming a passivation layer covering an inner wall of each of the trenches; and dicing the passivation layer and the insulating layer along each of the trenches to form a plurality of chip packages.
