Patent attributes
A stack structure of circuit boards embedded with semiconductor chips is proposed. At least two circuit boards are provided. Each of the circuit boards includes circuit layers formed on surfaces thereof and at least one opening embedded with a semiconductor chip, wherein, the circuit layers have a plurality of conductive structures and electrically conductive pads, and the semiconductor chip has a plurality of electrode pads, and the conductive structures of the circuit layers are electrically conductive to the electrode pads of the semiconductor chip. At least one adhesive layer is formed between the two circuit boards and disposed with a conductive material corresponding in position to the electrically conductive pads of the circuit boards. Thus, a conductive path can be formed by the conductive material between the electrically conductive pads of the circuit boards, thereby establishing electrical connection between the two circuit boards.
