A bonding wire f made of, for example, gold is used as a connection between the lead and the lead b. The wire f is connected to the electrode e by ball bonding from the viewpoint of electrical connectivity, and is bent in an arch shape. And, there is a problem that this bending is a factor restricting the thinning of the resin package g. In a resin-encapsulated semiconductor device, it is strongly required to reduce the thickness of a resin package, and the thickness of the resin package is reduced to 1.
Since there is a demand for the thickness to be 0 mm or less, the problem that the bending of the wire restricts the thinning of the resin package cannot be overlooked.

As proposed by the applicant of the present invention, removing the die pad, connecting the semiconductor element electrode and the inner lead with a bonding wire while the semiconductor element is free from the lead frame, and holding the semiconductor element by this inner lead. Was attempted. This is because the thickness of the semiconductor device can be reduced by the thickness of the die pad. However, it is mechanically unstable to support the semiconductor element only by the bonding wire connecting the lead and the electrode of the semiconductor element. Therefore, there is a problem that the position of the semiconductor element shifts after wire bonding before resin sealing or during resin sealing, which causes a problem of disconnection of a wire and occurrence of a short circuit due to contact of the wire.

It is an object of the present invention to reduce the thickness of the semiconductor device without impairing the stability of supporting the semiconductor element in a semiconductor device in which the electrodes are electrically connected to the inner leads by a boding wire.

According to this semiconductor device, since the connecting means is lower than the bonding wire, it does not cause any increase in the thickness of the semiconductor device.

Therefore, connection by wedge bonding becomes possible,
Therefore, the height of the arch due to the bending of the wire can be reduced. Accordingly, the thickness of the semiconductor device can be reduced.

Further, since the semiconductor element can be firmly supported by the support leads via the insulating tape, the position stability from the wire bonding of the semiconductor element to the end of the resin sealing can be improved. And, since the insulating tape is interposed between the supporting lead and the semiconductor element, the semiconductor element can be firmly supported, so that the bonding wire does not have a role of supporting the semiconductor element, and merely has a role of electrical connection. I only had to do it.
Therefore, the bonding wire may be longer or shorter, and as a result, the range in which the size of the semiconductor chip can be accommodated by a lead frame of the same size can be expanded. In other words, not only can a large lead frame be used for a large semiconductor element (chip), but also a relatively small semiconductor element chip can be used.

FIG. 3 is a perspective view showing a state before resin sealing, and FIG. 4 is a sectional view showing a state after resin sealing. It is. In this embodiment, the present invention is applied to a DILP-type semiconductor device. Support leads 2, 2, 2, and 2 are provided on two sides on which inner leads 1, 1,. Is provided. Then, the semiconductor element 3 is supported by the supporting leads 2, 2, 2, 2 via the insulating tape 10.
More specifically, the intermediate portion of the insulating tape 10 is adhered to the upper surface of the semiconductor element 3, and both end portions of the insulating tape 10 are adhered to the upper surfaces of the tips of the support leads 2, 2, 2, 2. 2, 2, 2 form a state in which the semiconductor element 3 is supported via the insulating tape 10.

2, 2 and 2, the semiconductor element 3 via the insulating tape 10
May be formed. Thereafter, resin sealing is performed. Then, portions of the support leads 2, 2, 2, and 2 protruding from the resin package 9 to the outside are removed when unnecessary portions of the lead frame are removed. According to the present semiconductor device, the thickness of the resin package 9 can be reduced by the absence of the die pad and the connection silver paste film. Further, since the semiconductor element 3 is stably supported by the support leads 2, 2, 2, and 2 via the insulating tape 10, the semiconductor element 3 is positioned between the time after the wire bonding and the time of resin sealing and during the resin sealing. There is no danger that the semiconductor element 3
There is no risk of disconnection of the wire 7 and occurrence of short-circuit failure between the wires 7 due to misalignment.

対応できる範囲が広くなる。Since the insulating tape 10 has a thickness of only about 10 μm, which is lower than the height of the arch (150 μm) of the bonding wires 7, 7,... There is no possibility that the thickness may be increased. Further, since the thickness of the lead does not become a factor for increasing the thickness of the semiconductor device, the thickness of the lead can be increased to have sufficient strength against the bending of the lead. Then, the support leads 2 are provided via the insulating tape 10,
Since the semiconductor element 3 can be firmly supported by 2, 2, and 2, the range in which the same lead frame can cope with the difference in chip size is wider than in the case of the technology of Japanese Patent Application No. 1-297174. Become.

るリードフレームの適合範囲を広くできる。That is, according to the technique of Japanese Patent Application No. 1-297174, since the semiconductor element is supported only by the inner lead via the bonding wire, the tip of the inner lead and the semiconductor element are required for proper support of the semiconductor element. It is essential that the distance from the side surface and the length of the bonding wire be equal to or less than a certain value, and it is difficult to use a lead frame designed for a large chip for a small chip. However, according to the present semiconductor device, the bonding wire only needs to make electrical connection between the inner lead and the electrode of the semiconductor element, so that the bonding wire may be slightly longer. Therefore, the distance between the tip of the inner lead and the side surface of the semiconductor element may be large. Accordingly, a lead frame for a large semiconductor element can be used for a small semiconductor element, and the range of adaptation of the lead frame to the chip size can be widened.

The support lead adhesive piece 11 has a shape having
11, 11, 11 are bonded to the support leads 2, 2, 2, 2. Of course, it goes without saying that the rectangular portion as the main body of the insulating tape 10 is adhered to the upper surface of the semiconductor element 3. As described above, by deforming the insulating tape 10, the present invention can be applied to the QFPIC in a mode in which the insulating tape is used as a connecting means.

要因には全くならない。According to the semiconductor device of the first aspect, since the semiconductor element is supported by the support lead via the connecting means, the position stability from the wire bonding of the semiconductor element to the end of the resin sealing is improved. Can be.
According to the semiconductor device of the second aspect, since the connecting means is lower than the bonding wire, it does not cause any increase in the thickness of the semiconductor device.

Therefore, connection by wedge bonding becomes possible,
Therefore, the height of the arch due to the bending of the wire can be reduced. Accordingly, the thickness of the semiconductor device can be reduced.

きる。According to the semiconductor device of the fourth aspect, since the connecting means is formed of an insulating tape, and the insulating tape is extremely thin, for example, about 10 μm, it does not cause any increase in the thickness of the semiconductor device. Further, since the semiconductor element can be firmly supported by the support leads via the insulating tape, the position stability from the wire bonding of the semiconductor element to the end of the resin sealing can be improved. And, since the insulating tape is interposed between the supporting lead and the semiconductor element, the semiconductor element can be firmly supported, so that the bonding wire does not have a role of supporting the semiconductor element, and merely has a role of electrical connection.
