Abstract
A manufacturing method of a semiconductor device includes the following steps. A semiconductor wafer having an active side and a back side opposite to the active side is provided. A plurality of conductive bumps are provided on the active side. A protection film is laminated on the active side, wherein the protection film includes a dielectric film covering the plurality of conductive bumps and a cover film covering the dielectric film. A thinning process is performed on the back side to form a thinned semiconductor wafer. The cover film is removed from the dielectric film. A singularization process is performed on the thinned semiconductor wafer with the dielectric film to form a plurality of semiconductor devices.
