Filed: 1995-12-26
Abstract: PROBLEM TO BE SOLVED: To reduce the possibility of open-circuit failures caused by peeling of junctions of bump electrodes or caused by step breaking of chip wiring lines in a transistor element and thus to reduce the possibility of stress causing damages to the transistor element. SOLUTION: An input/output terminal bump electrode 820 is adjustably provided on an peripheral edge part of a semiconductor chip base 500 through a lower structure 612 disposed therebetween, so that a total height hs of the lower structure 612 and bump electrode 820 from a surface of the semiconductor chip base 500 is greater than a height ht of an element bump electrode 810. This enables reduction of stress imposed on a transistor element 600 at the time of mounting a semiconductor chip 400 on a wiring board to thereby increase a bonding strength of the input/ output terminal bump electrode 820 as a junction, Step breaking can be prevented by making large a lower chip wiring part of the input/output terminal bump electrode 820, forming a polyimide coating film on a side face, or forming the lower structure 612 into a mesa shape.
