Semiconductor package with substrate having single metal layer and manufacturing methods thereof

Abstract

A semiconductor package includes a substrate, a die, and a package body. The substrate includes: (a) a core including a resin reinforced with fibers; (b) a plurality of openings extending through the core; (c) a dielectric layer; and (d) a single conductive layer disposed between the dielectric layer and the core. Portions of a lower surface of the single conductive layer cover the plurality of openings to form a plurality of first contact pads for electrical connection external to the semiconductor package. Exposed portions of an upper surface of the single conductive layer form a plurality of second contact pads. The die is electrically connected to the plurality of second contact pads, and the package body encapsulates the die.
