    • PURPOSE: A stacked flip chip package using a carrier tape is provided to reduce a manufacturing cost and to shorten a manufacturing process, by flip-chip-bonding semiconductor chips by using a metal thin film and a carrier tape composed of an adhesion film such as an anisotropic conductive film or elastomer film having an opening which is adhered to an upper/lower surface of the metal thin film. CONSTITUTION: A carrier tape(150) has a metal thin film of a predetermined pattern and anisotropic conductive films(140). The metal thin film(130) includes bump connecting units(132) and beam leads(134) in both end parts. The anisotropic conductive films are adhered to upper and lower surfaces of the metal thin film excluding the beam leads. A plurality of semiconductor chips(110,120) are adhered to an upper surface of the anisotropic conductive films and have bumps while each bump corresponds to the bump connecting unit. The carrier tape to which the semiconductor chips are adhered is mounted on an upper surface of a substrate(160), and solder balls are installed on a lower surface of the substrate. A region including the carrier tape is molded with a molding resin(170). The bump pressures the anisotropic conductive films to be electrically connected to the bump connecting unit, and the beam leads are bent to be electrically connected to the substrate.
