Abstract:
A method of manufacturing a semiconductor package comprising:(a) attaching a semiconductor chip having bonding pads along a central line on an active surface of the semiconductor chip to a tape wiring substrate, wherein an elastomer interposes between the active surface of the semiconductor chip and the tape wiring substrate, and the tape wiring substrate comprises an opening, a plurality of beam leads which are exposed through the opening of the tape wiring substrate, a plurality of terminal pads which are extensions of the beam leads, and a plurality of via holes through which the terminal pads are exposed; (b) bonding the beam leads to the bonding pads which are exposed through the openings of the tape wiring substrate and the elastomer; (c) attaching a cover film to a tap surface of the tape wiring substrate and turning the top surface down; (d) encapsulating the opening and side surfaces of the elastomer and the semiconductor chip with an encapsulant, wherein the encapsulating comprises: (d-1) dispensing the encapsulant on a portion of the tape wiring substrate that is close to one end of the openings of the elastomer so that the encapsulant can flow into and fill the opening from the one end; and (d-2) dispensing the encapsulant on the tape wiring substrate along a perimeter of the semiconductor chip so that the encapsulant can cover side surfaces of the elastomer and the semiconductor chip; and (e) curing the encapsulant and removing the cover film from the tape wiring substrate.
