Definitions
- the present invention relates to an adhesive composition excellent in electrical conductivity, thermal conductivity and adhesiveness. More specifically, an adhesive composition suitable for bonding semiconductor elements such as ICs, LSIs, and light emitting diodes (LEDs) to a substrate such as a lead frame, a ceramic wiring board, a glass epoxy wiring board, a polyimide wiring board, and the like.
- the present invention relates to a semiconductor device.
- a semiconductor element and a lead frame (support member) can be bonded to each other by dispersing a filler such as silver powder in a resin such as an epoxy resin or a polyimide resin, and then pasting (for example, silver As a paste), there is a method of using this as an adhesive.
- a paste adhesive is applied to a die pad of a lead frame using a dispenser, a printing machine, a stamping machine, etc., and then a semiconductor element is die-bonded and bonded by heat curing to obtain a semiconductor device.
- the semiconductor device is further sealed with a sealing material and packaged with a semiconductor, and then soldered and mounted on a wiring board. Since recent mounting requires high density and high efficiency, the surface mounting method in which the lead frame of the semiconductor device is directly soldered to the substrate is the mainstream. For this surface mounting, reflow soldering for heating the entire substrate with infrared rays or the like is used, and the package is heated to a high temperature of 200 ° C. or higher. At this time, if moisture exists in the inside of the package, particularly in the adhesive layer, the moisture is vaporized and wraps around between the die pad and the sealing material, and a crack (reflow crack) is generated in the package. This reflow crack significantly reduces the reliability of the semiconductor device, and is therefore a serious problem / technical problem. Adhesives often used for bonding between semiconductor elements and semiconductor support members are bonded at high temperatures. Reliability such as power has been demanded.

- FIG. 4 is a schematic diagram showing a state in which the silver particles having a large amount of oxide film shown in FIG. 3 are removed by heating, but the silver particles cannot be sintered together.
- the mechanism of high thermal conductivity and high electrical conductivity in the present invention is that the surface protective material is desorbed by heating, and the silver particles with exposed active surfaces are contacted and bonded to each other, so that metal bonding by sintering is performed between the silver particles. It was considered that high thermal conductivity and high electrical conductivity were achieved. That is, conventionally, heating at 200 ° C. or higher is required for sintering, and particles of 0.1 ⁇ m or less have been considered to have excellent sinterability, but the active surface of silver particles is exposed by heating or the like. By designing such particles, sintering occurs even if the heating temperature is 200 ° C. or less, or the silver particle diameter exceeds 0.1 ⁇ m, and a metal bond path between silver particles is formed, and high heat We thought that conductivity and high electrical conductivity could be achieved.

It has been confirmed that silver particles cannot be obtained. Therefore, in order to prevent the aggregation of silver particles, it is necessary to add a surface protective material to the acidic solution to simultaneously remove the oxide film and protect the surface.

In order to prevent adsorption, the amount is preferably 1 part by weight or less.
- the proportion of the silver particles in the adhesive composition is preferably 80 parts by weight or more in 100 parts by weight of the adhesive composition in order to improve the thermal conductivity, in order to achieve a thermal conductivity equivalent to or higher than that of the high-temperature solder.
