ABSTRACT:
A semiconductor package forming method includes mounting a backgrinding-underfill film which includes a laminated backgrinding film and a laminated underfill film on a semiconductor wafer so that the underfill film adheres to a front side of the semiconductor wafer; backgrinding a back side of the semiconductor wafer on which the backgrinding-underfill film has been mounted and removing the backgrinding film of the backgrinding-underfill film from the semiconductor wafer. The method further includes dicing the semiconductor wafer from which the backgrinding film has been removed, so that semiconductor chips are separated from the semiconductor wafer.
