Patent ID: 7985618

Claim:
A fabrication method of a semiconductor device, comprising the steps of: preparing a carrier having at least one opening, the carrier comprising at least one substrate, wherein a portion of the substrate is connected to a slanted side of the at least one opening; mounting at least one chip and at least one passive component on the substrate of the carrier; electrically connecting the chip to the substrate; performing a molding process to form an encapsulant on the carrier for encapsulating the at least one chip and the at least one passive component, wherein the encapsulant has a side including a portion corresponding to the slanted side of the opening of the carrier and a portion corresponding to a side of the substrate, and the portion of the side of the encapsulant is at least not smaller than the corresponding side of the substrate, and wherein the encapsulant is formed with a cutaway corner corresponding to the slanted side of the opening of the carrier, and a predetermined distance is formed between the cutaway corner of the encapsulant and the slanted side of the opening; performing linear cutting on the carrier along sides of the substrate to form a package having a size identical to surface area of the substrate, wherein the portion of the substrate connected to the slanted side of the opening is formed as a slanted side of the substrate, and a portion of the substrate located between the slanted side thereof and the cutaway corner of the encapsulant is exposed from the encapsulant to form an exposed portion of the substrate; and mounting a lid having a chamfer to the package to form the semiconductor device, wherein the slanted side of the substrate is coupled to the chamfer of the lid.
