Abstract:
1. A fabrication method for a semiconductor CSP type package, comprising the steps of: cutting a wafer on which LSI chips with LSI pads are formed to separate said LSI chips; providing gaps around said LSI chips at equal intervals to array said LSI chips; filling said gaps with a chip layer insulative resin and allowing the resin to cure; forming at least one wire layer electrically connected to the LSI pads and at least one wire layer resin; forming CSP pads on the wire layer resin electrically connected to the at least one wire layer; and slicing through the chip layer resin and the at least one wire layer resin to separate the LSI chips from one another to provide a plurality of the CSP packages; wherein, in plan view of the CSP package: a perimeter of the chip layer resin and wire layer resin lies entirely outside a peripheral edge of said LSI chip; and at least one of the CSP pads extends outside the peripheral edge of the LSI chip.
