Abstract

PURPOSE:To obtain an IC frame which can be used commonly for individual IC chips and in which wires of a stitched part are not short-circuited with a die pad by providing a ringlike stitch on the periphery of the pad for placing an IC chip, and insulating predetermined positions of the stitch and the stitch parts of outer leads to be bonded. CONSTITUTION:A ringlike stitch such as a GND only stitch 10 is provided on the periphery of a die pad 5. A stitch part 7 is bonded to a GND only ringlike stitch 10 at an adhesive part 11 with insulating adhesive to form an IC frame 12. If a GND line is considered to be strengthened by increasing a circuit current, bonding pads 3 may be connected to the stitch 10. Since the stitch 10 is formed in the ring state, a GND line can be simply strengthened if GND bonding pads may be mounted at arbitrary positions in an IC chip 1. Since a stitched part 7 and the stitch 10 are insulated at the part 11 at all intersections, the IC frame can be easily manufactured.

Recently, highly integrated ICs such as gate array type,
Chips made using the standard cell method require considerably more circuit current. At the same time, operating frequencies have also increased, and ICs that increasingly use logic tend to require increased circuit currents. As a method corresponding to this, the method shown in FIG. 2 described above has been adopted. That is, the IC chip 1 is placed on the die pad 5, and the stitched portion 7 that becomes the external electrode of the IC and the bonding pad 2 of the IC are connected to the wire 6.
By making the connection, the internal electrodes of the IC chip 1 will be exposed to the external pins. Moreover, if the bonding pad 4 in the IC chip 1 is connected to the GND line,
By connecting to an external stitch, the GND line will come out as an external pin. In this way, normal pins were processed.

However, the above-mentioned increase in circuit current can be countered by extending more GND pins to the outside.
In many cases, it is not possible to produce as many pins as possible due to constraints. As a countermeasure, as shown in FIG.
That is, a stitched portion 8 is provided, and this stitched portion 8 and the bonding pads 3 and 4 of the IC chip 1 are connected by a wire 6.
By connecting the GND of the IC chip 1 to the outside, the same function as connecting the GND of the IC chip 1 to the outside is achieved.
