Abstract:
A method of making semiconductor devices, comprising the steps of:preparing non-defective individual film packages having good quality, wherein each of said non-defective individual film packages has a flexible substrate having a front surface on which a wiring pattern in formed and a back surface opposite thereof, and a semiconductor chip having electrodes that are connected to said wiring pattern, said flexible substrate being larger than said semiconductor chip;attaching the back surface of each of said non-defective individual film packages to each of mounting regions of a reinforcing member, said reinforcing member maintaining a planar configuration for said flexible substrate and circumventing said semiconductor chip; andcutting said reinforcing member into separate pieces, each of said separated pieces corresponding to each of said mounting regions on which each of said non-defective individual film packages is mounted.
