ABSTRACT:
A conductive resin composition primarily comprising (A) 100 parts by weight of a thermosetting or thermoplastic resin, (B) 5–2,000 parts by weight of a conductive filler, and (C) 0.1–300 parts by weight of organic resin or rubber particulates has a low volume resistivity and stability thereof, and is effectively adherent. When applied to semiconductor packages, the composition can prevent the semiconductor chips from warpage or cracking due to thermal stresses in the semiconductor packages, ensuring the fabrication of semiconductor devices with high reliability.
