Abstract

1,188,451. Semi-conductor devices. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. 22 Jan., 1969 [26 Jan., 1968], No. 4192/68. Heading H1K. In making connection to a semi-conductor or integrated circuit device two frame-lead assemblies are used, one being a fairly large structure and the other being a finer one which is used to connect the ends of the fingers of the large one to bonding pads on the device. The device 4 may be carried by the fingers of the finer frame 7<SP>1</SP>, as shown, or may be carried by a relatively massive finger (acting as a heat sink) of the large frame 1<SP>11</SP>. In the finished structure the fingers of the finer frame may be substantially in the plane of the frame itself or may be looped from that plane. The finer frame has no backing substrate but the large frame may be constituted by tracks on a printed circuit.
