Abstract

See full text

Epoxy-amine underfill materials for semiconductor packages and semiconductor packages having an epoxy-amine underfill material are described. In an example, a semiconductor apparatus includes a semiconductor die having a surface with an integrated circuit thereon. A semiconductor package substrate has a surface with a plurality of contact pads thereon. A plurality of conductive contacts couples the surface of the semiconductor die to the surface of the semiconductor package substrate. An epoxy-amine underfill material is disposed between the surface of the semiconductor die and the surface of the semiconductor package substrate and surrounds the plurality of conductive contacts. The epoxy-amine underfill has high adhesion and is based on a low volatility multi-functional amine species.
