Leiterrahmen für Halbleiteranordnung

摘要

A lead frame for a semiconductor device having: first and second frame portions (1, 1) facing each other and spaced apart by a predetermined distance; an island (4) formed at a position sandwiched between the first and second frame portions (1, 1) for mounting a semiconductor chip; a pair of tie bars (22, 22) for integrally coupling the first frame portion (1) and a side of the island (4) facing the first frame portion, the pair of tie bars (22, 22) being formed with a predetermined space in the widthwise direction; and a pair of tie bars (22, 22) for integrally coupling the second frame portion (1) and a side of the island (4) facing the first frame portion, the pair of tie bars (22, 22) being formed with a predetermined space in the widthwise direction.
