Abstract:
1. A carrier structure for a semiconductor chip comprising: a carrier board having at least one through cavity in which a semiconductor chip, having an active surface with a plurality of electrode pads thereon and an opposite inactive surface, is disposed; an adhesive material filling the gap between the through cavity of the carrier board and the semiconductor chip in order to fix the semiconductor chip, wherein a revealed surface of the adhesive material is a concave surface; and a built-up structure having at least one dielectric layer, wherein the dielectric layer is formed on the active surface of the semiconductor chip, on one surface of the carrier board on the same side with the active surface of the semiconductor chip, and on the concave surface of the adhesive material so that the combination of the dielectric layer and the concave surfaces of the adhesive material is advantageous to disperse the stress between different materials.
