Abstract:
1. A method of manufacturing a semiconductor package, the method comprising: attaching a semiconductor substrate on a support substrate using an adhesive layer, wherein the semiconductor substrate comprises a plurality of first semiconductor chips and a chip cutting region, wherein first and second ones of the plurality of first semiconductor chips are separated from each other by the chip cutting region, and the semiconductor substrate includes a first surface on which an active area is formed and a second surface opposite to the first surface; forming a first cutting groove having a first kerf width in the chip cutting region between the first and second ones of the plurality of first semiconductor chips, so that the semiconductor substrate is separated into a plurality of first semiconductor chips; attaching a plurality of second semiconductor chips corresponding to the first semiconductor chips, respectively, to the plurality of first semiconductor chips; forming a molding layer so as to fill the first cutting groove; and forming a second cutting groove having a second kerf width that is less than the first kerf width, in the molding layer, so as to separate the molding layer into individual molding layers covering one of the plurality of first semiconductor chips and corresponding one of the plurality of second semiconductor chips.
