Definitions
- the present invention relates to a paste composition using a thermoplastic resin, a protective film using the same, and a semiconductor device.
- Techniques for improving reflow resistance by modifying the sealing material include the combination of fillers and resins.
- the composition By changing the composition, it is common to reduce the moisture absorption rate of the sealing material to reduce the amount of water absorbed by the package during storage, and to increase the adhesive strength to a substrate or the like.
- a material showing good riff resistance, especially for a liquid sealing material has not been proposed.
- the amount of filler such as silicide is increased to make the sealing material low in moisture absorption. In this case, it is possible to reduce the linear expansion of the sealing material, and it is possible to obtain an effect that damage to the semiconductor element is reduced.
- a method of providing a through hole for discharging vaporized moisture generated inside the semiconductor package at the time of mounting and heating there is a method of providing a through hole for discharging vaporized moisture generated inside the semiconductor package at the time of mounting and heating.
- moisture may enter the inside of the semiconductor element, and consequently, there is a problem that important moisture resistance is not always sufficient as well as riff resistance.
- the method of selectively sealing the back surface of a semiconductor element with a porous resin body requires a step of previously disposing the porous resin sheet in a mold, which is problematic in productivity. Furthermore, it was difficult to apply to semiconductor packages such as cavity type BGA and BGA which are difficult to seal by transfer molding using a mold.
- the present invention has been made in order to solve these problems, and has been made of a paste composition for semiconductor encapsulation that achieves both good reflow resistance and moisture resistance reliability, and a protective film using the same. To provide a semiconductor device with excellent heat resistance and moisture resistance reliability. Aim.
- the present inventors have conducted various studies in order to solve the above problems, and as a result, produced a paste composition in which an inorganic filler was dispersed in a solution in which a resin was dissolved in an organic solvent, and used to prepare Ic and LSI chips. It has been found that a semiconductor element having both good reflow resistance and moisture reliability can be obtained by coating and drying on the top. This is because, in a coating film in which such a paste composition is hardened, voids remaining between the particles of the filler and fine voids which are evaporation paths of the organic solvent remain inside the coating film. This is probably due to the formation of a layer densely filled with resin with low moisture permeability on the membrane surface.
- the present invention comprises (A) a thermoplastic resin, (B) an epoxy resin, (C) a coupling agent, (D) a powdery inorganic filler, (E) a powder having rubber elasticity, and (F) an organic solvent.
- the thermoplastic resin (A) is obtained by polycondensing an aromatic dicarboxylic acid, an aromatic tricarboxylic acid or a reactive acid derivative thereof with a diamine containing diamino silicone as an essential component. It is preferably a polyimide silicone copolymer or a polyamideimide silicone copolymer.
- the epoxy resin (B) is preferably an alicyclic epoxy resin.
- the coupling agent (C) is preferably one or more force coupling agents selected from the group consisting of silane coupling agents, titanate coupling agents, and aluminate coupling agents.
- the rubber elastic powder (E) is preferably a silicone rubber powder.
- the present invention also provides a porosity obtained by applying and drying the above paste composition on the surface of a semiconductor component at 3% by volume or more, and having a moisture permeability of 500 g / at 40 ° C. and 90% RH. m 2 - and provides a 2 4 h following the protective film.
- the present invention also provides a semiconductor device having the above protective film.
- the protective film is a sealing material for sealing a chip in the semiconductor device.
- the ratio of the void having a diameter of 2200 ⁇ m is 1 to 100% by volume of the volume of the void having a diameter of 0.0032 to 100 m in the sealing material.
- the chip is mounted on the chip supporting substrate, and the chip supporting substrate is connected to the inner connecting portion to which the terminals of the chip are connected, and the outer connecting portion for connecting to the outside of the semiconductor.
- a wiring portion for connecting the inner connection portion and the outer connection portion is a wiring pattern formed on one surface of the insulating base material, and the outer connection portion is formed on the back surface of the insulating base material and connected to the wiring pattern by the wiring portion.
- the chip is bonded to the surface of the insulating substrate on which the wiring pattern is formed with an adhesive for bonding a semiconductor element, and the terminals of the chip and the wiring pattern are gold wires. Preferably they are connected.
- FIG. 1 is a cross-sectional view illustrating one embodiment of the semiconductor device of the present invention. BEST MODE FOR CARRYING OUT THE INVENTION
