Method for fabricating semiconductor packages

摘要

A method for fabricating semiconductor packages is proposed. A plurality of substrates are prepared each having a chip thereon. Length and width of each substrate are equal to predetermined length and width of the semiconductor package. A carrier having a plurality of openings is prepared. A protruded portion is formed at each corner of each opening, wherein a distance between two diagonal protruded portions is slightly larger than that between two diagonal corners of the substrate. The substrates are fixed in the openings of the carrier by means of the protruded portions, and gaps between the substrates and the carrier are sealed. An encapsulant is formed over each opening to encapsulate the corresponding chip by a molding process. An area on the carrier covered by the encapsulant is larger in length and width than the opening. A plurality of the semiconductor packages are formed after performing mold-releasing and singulation processes.
