Abstract
A film carrier semiconductor device 10 comprises a semiconductor bare chip 20 and a carrier film 30. Chip electrodes 21 are provided on the bare chip 20. Each chip electrode 21 is electrically connected to the carrier film 30. Bump electrodes 37 are formed and arranged as an array on the carrier film 30 on the side of the other surface 31b of the film 30. Interconnection layers 32 are provided on the carrier film 30 to connect some of the chip electrodes 21b to the bump electrodes 37a and 37b. The semiconductor device 10 also comprises a noise blocking layer 60 provided on the carrier film 30 outside the chip mounting region. The noise blocking layer 60 is electrically connected to at least one of the chip electrodes 21a.
