Abstract

Provided is a method of fabricating a semiconductor package. The method includes preparing a package substrate having a substrate pad, and mounting a semiconductor chip on the substrate pad. Mounting the semiconductor chip includes forming a resin layer containing a solder and reducing agent granules having a first capsule layer, between a chip pad of the semiconductor chip and the substrate pad, and bonding the chip pad to the substrate pad using laser irradiated to the semiconductor chip.
