Abstract:
1. A substrate for a semiconductor package, comprising: a core layer, at least a metal layer applied over at least a surface of the core layer, the metal layer being defined with a conductive region and a peripheral region surrounding the conductive region, wherein the conductive region is adapted to form a plurality of conductive traces, and each of the conductive traces has a terminal; and an insulating layer applied over the metal layer, allowing the terminals of the conductive traces and at least a corner portion of the peripheral region to be exposed to outside of the insulating layer, wherein a gap is formed between exposed corner portions of the metal layers of vertically stacked substrates and a portion of the substrate corresponding in position to the peripheral region of the metal layer is cut off and thus removed from the semiconductor package in a singulation process for cutting apart batch-fabricated substrates.
