Abstract:
A method of making a very thin chip size semiconductor package (â€œVCSPâ€ ), comprising:providing an insulative substrate having a plurality of conductive pads on a first surface thereof, a plurality of lands on a second surface thereof, and means for electrically connecting the pads to the lands through the substrate; providing a semiconductor die having a first surface with a plurality of conductive pads thereon and a thickness substantially less than an initial thickness of a semiconductor wafer from which the die was singulated; forming a flip chip electrical connection between the die and the substrate; and, underfilling a space defined between the respective first surfaces of the die and the substrate and circumscribing a periphery of the die with a first insulative material; and filling a space around the periphery of the die and above the first insulative material with a second insulative material, said second insulative material contacting the first insulative material outward of the periphery of the die.
