Abstract:
1. A stack structure of circuit boards with semiconductor components embedded therein, comprising: at least two circuit boards each having a first circuit layer formed thereon and a cavity formed therein, wherein the cavity is used to receive a semiconductor component having a plurality of electrode pads, and the first circuit layer is formed with a plurality of first electrical connection pads and a plurality of first conductive vias for electrically connecting the electrode pads of the semiconductor component and the first electrical connection pads of the first circuit layer, wherein one end of each of the first conductive vias is directly connected to corresponding one of the first electrical connection pads, and the other end of the each of the first conductive vias is directly connected to corresponding one of the electrode pads; a plurality of conductive bumps formed on the first electrical connection pads of at least one of the circuit boards; and at least an adhesive layer interposed between the circuit boards, allowing a conductive channel to be formed by a portion of the adhesive layer positioned between the conductive bumps of one of the at least two circuit boards and the first electrical connection pads of another one of the at least two circuit boards corresponding thereto, such that an electrical connection between the circuit boards is formed, wherein the adhesive layer is an anisotropic conductive adhesive comprising an adhesive resin, a hardening agent, and conductive particles.
