摘要：
The present invention is premised on a semiconductor device in which one semiconductor chip is mounted on each of both faces of a die pad of a lead frame. The semiconductor chips are disposed such that the projected lines, on the die pad, of the corresponding sides of the semiconductor chips, intersect with each other at an angle of 45.degree.. The tips of inner leads are located in the sides of a virtual octagon formed by outwardly enlarging an octagon formed by connecting, to one another, the apexes of the semiconductor chips. The sides of the virtual octagon are respectively opposite to the sides of the semiconductor chips. The number of the inner leads of which tips are located in each of the sides of the virtual octagon, is the same as the number of bonding pads disposed at each of the sides of the semiconductor chips. The inner leads of which tips are located in each of the sides of the virtual octagon, are connected to the bonding pads at each of the sides of one of the first and second semiconductor chips.
