摘要:
A semiconductor device which can reduce the transmission loss of high-frequency signals and in which a semiconductor chip (6) is facedown-bonded to a ground plane TAB tape (4). The TAB tape (4) is such that a first conductive layer (2) and a second conductive layer (3) are respectively formed on the front and rear sides of an insulating layer (1) and a front-side of the second conductive layer (3) is exposed in an opening made in the insulating layer (1) and Au bumps (7a and 7b) are protruded in the openings of the conductive layers (2) and (3). The pad electrode (5) of the semiconductor chip (6) is matched and bonded to the Au bumps (7a and 7b) on the TAB tape (4) without melting the bumps (7a and 7b). This semiconductor device can be used for information communication equipment and a highly advanced system can be constructed when the device is constituted in a multichip module.
