The present invention relates to an insulating resin paste used in a resin joining method in which bubbles are extremely generated even when cured in a short time.

Conventionally, as a method of die-bonding a semiconductor element to a lead frame or the like, a gold-silicon eutectic method of bonding by forming a eutectic of gold and silicon, and a solder bonding method of bonding using a solder paste are mainly used. Has been used.
The gold-silicon eutectic method has a drawback that the cost is very high because gold is used, or the working temperature is high at 400 to 450 ° C., which causes deterioration of semiconductor elements and parts. On the other hand, the solder joining method has a drawback that the heat resistance is inferior although the cost is relatively low, or the semiconductor element is deteriorated due to scattering of solder balls.

Under such circumstances, recently, a resin bonding method using a conductive or insulating paste in which an inorganic powder such as a silver powder or a silica powder is dispersed in a resin has been used.
This resin bonding method can greatly reduce the cost. Particularly, the insulating resin paste using silica powder is inexpensive because no precious metal is used at all, and its characteristics are also very excellent.

However, the conventional insulating resin paste used in these resin bonding methods has a drawback that bubbles are easily generated during curing. This is because it is necessary to disperse an inorganic powder such as silica powder in a resin to form a paste, so the resin contains a large amount of solvent or must be liquid at room temperature. When the paste is hardened, it is partially vaporized to generate bubbles, or when the resin and the inorganic powder are kneaded, air is included to form bubbles.

If these bubbles do not escape smoothly during curing, the bubbles will remain in the cured product and the adhesion strength between the semiconductor element and the lead frame will be significantly reduced, or the force when the bubbles escape will cause the semiconductor chip to tilt and remain tilted. They will be joined together, which will cause a serious defect that the position cannot be recognized by the automatic bonder in the gold wire wire bonding in the subsequent process.

Bubbles generated when the paste is cured are present on the surface of the filler, and when the liquid resin composition is mixed with an inorganic filler, the surface of the filler is not sufficiently wet to the liquid resin composition. This is an unavoidable problem when an inorganic filler is added to the liquid resin composition.

The present inventors have paid attention to reducing the amount of the filler as the source of generation of bubbles as much as possible, and as a result of extensive studies, the use of ultrafine silica powder in combination can significantly reduce the inorganic filler, It has been found that the ultrafine silica powder itself does not become a source of air bubbles, and that when a phenol novolac and a latent amine compound are used as a curing agent, the adhesive strength at the time of heating remarkably increases.

It is considered that the bubbles generated during the curing of the insulating paste are present on the surface of the filler. Therefore, the bubbles can be reduced by reducing the amount of the filler. However, when the amount of the filler is usually reduced, the viscosity and the degree of thixotropy of the paste become small, which causes dripping of the paste from the dispenser, bleeding or the like, which is practically inconvenient. In addition, the heat resistance is lowered, and there is a disadvantage that the chip is peeled off in the wire bonding process which requires high adhesive strength at high temperature. Therefore, the compounding amount of the filler of the insulating paste for semiconductors is usually at least 40% by weight or more.

The silica filler used in the present invention has an ultrafine particle size of 0.
The feature is that silica of 005 to 0.02 μm is used in combination, but even if such ultrafine particle silica is compounded in the liquid resin composition, there should be no large bubbles on the surface of the silica that may tilt the chip during curing. However, they have found that they do not become a source of bubbles that cause inconvenience. Moreover, since the viscosity and thixotropy become remarkably large only by adding a small amount, dripping of the paste from the dispenser or bleeding does not occur even if the amount of the filler in the insulating paste is reduced. Further, the silica filler used in the present invention contains 60 to 85% by weight of silica powder having a maximum particle size of 50 μm or less and an average particle size of 2 to 5 μm, but if it is less than 60% by weight, heat resistance and thermal conductivity decrease. In addition, the amount of ultrafine silica becomes too large, and the viscosity and the degree of thixotropy become extremely high, and the paste is pulled into a thread shape at the time of application with a dispenser, and the chip cannot be mounted. On the other hand, if the blending amount is more than 85% by weight with the average particle diameter of 2 to 5 μm, the content of the ultrafine silica powder is too small and the effect of the present invention is not sufficiently exerted. Further, the particle size of the silica powder used in the present invention is limited to 50 μm or more, but if the particle size is larger than this, when applying paste with a dispenser, a fine needle (diameter of 0.2 mm or less) has a silica powder near the outlet of the needle. This is because the particles gradually accumulate and eventually block the outlet, making continuous use impossible for a long time.

When the content of the silica filler in the insulating paste is low, the heat resistance is lowered, so the content is usually 40% by weight or more. However, in the present invention, the insulating paste having excellent heat resistance is obtained even when the content of the silica filler is 30% by weight or less by using the phenol novolac excellent in heat resistance and containing many benzene rings having good heat stability as the curing agent.

However, since phenol novolac is a solid, when it is used alone, the viscosity of the paste increases remarkably and is not suitable for practical use. Further, when a solvent is added for the purpose of improving this, voids are generated during curing. By using a latent amine compound having a smaller equivalent weight than that of phenol novolac in combination, an insulating paste having not so high viscosity and excellent heat resistance could be obtained.

The epoxy resin used in the present invention is limited to one which is liquid at room temperature, but a solvent is required for kneading with silver powder unless it is liquid at room temperature. The solvent causes bubbles and cannot be used in applications requiring fast curing at high temperature for a short time.

In addition, the amount of hydrolyzable chlorine contained in the epoxy resin is 500 p
Although limited to pm or less, the amount of chlorine extracted (pressure cooker) from the insulating paste can be significantly reduced by using such an epoxy resin. The extracted chlorine causes corrosion of aluminum wiring on the surface of the semiconductor element, so the smaller the amount of extracted chlorine, the higher the reliability.

Further, among the above epoxy resins, those having a boiling point of 250 ° C. or higher are very useful. This is because the resin pastes used in these materials have a low volatility of the resin, and therefore the viscosity does not change much even if they are continuously used.

In the present invention, the amount of silica filling in the insulating resin paste is limited to 5 to 30% by weight, but if it is less than 5% by weight, the viscosity and the thixotropy become small even though ultrafine particle silica is incorporated. , The dripping of the paste from the dispenser or bleeding will occur. On the other hand, if it is more than 30% by weight, the bubbles present on the surface of the silica filler will increase, and the effect of the present invention will be lost.

As described above, since the insulating resin paste for a semiconductor according to the present invention has very few bubbles during curing, it has been often generated in the conventional bonding of the semiconductor element and the external electrode.
The inclination or peeling of the semiconductor element is eliminated, and the reliability of bonding can be greatly improved. Further, since the content of hydrolyzable chlorine contained is extremely small, corrosion of the aluminum wiring on the surface of the semiconductor element hardly occurs and reliability can be improved.
