PACKAGING SUBSTRATE HAVING EMBEDDED SEMICONDUCTOR CHIP

摘要

A packaging substrate includes: a core board having opposite first and second surfaces and a cavity penetrating therethrough; a semiconductor chip disposed in the cavity and having an active surface with electrode pads and an opposite inactive surface; a first reinforcing dielectric layer containing a reinforcing material disposed on the first surface and the active surface and filling the gap between the chip and the cavity; a second reinforcing dielectric layer containing a reinforcing material disposed on the second surface and the inactive surface and filling the gap between the chip and the cavity; and first and second wiring layers disposed on the first and second reinforcing dielectric layers respectively and the first wiring layer electrically connecting to the electrode pads. The first and second reinforcing dielectric layers enhance the support force of the entire structure to thereby prevent delamination of the wiring layers from the dielectric layers and increase product yield and reliability.
