Abstract: A strip mainly includes a plurality of guide holes, a plurality of position holes, a plurality of separation holes, a plurality of second slots and a plurality of substrate areas. Guide holes are arranged on two sides of the strip for carrying during processing, and position holes are arranged at four corners of the strip for positioning on the machine during processing. Separation holes and slots are to be contiguous to the substrate areas and separate the substrate areas from one another so that the discontinuous warpage of the substrate area affects the peripheral substrate areas. Therefore, it can reduce the chance of breaking chip in the substrate area. The two ends of the substrate are adjacent to the slots to reduce the stress of other substrates in the longitudinal direction actuating the chip during heat treatment in processing. The strip further includes a metal layer surrounding the substrate areas to increase the stiffness of the entirety of the strip.

Abstract: A chip-scale semiconductor package mainly includes a semiconductor chip, a substrate and a package body. Said chip is attached onto said substrate by an adhesive layer. Said chip has a plurality of bonding pads formed thereon. Said adhesive layer has an aperture corresponding to the bonding pads of said chip such that the bonding pads can be exposed within an aperture. Said substrate has several through-holes respectively corresponding to the bonding pads of said chip and parts of the area around the edge of said chip for dispensing of encapsulant after the soldering of leads of said substrate to the bonding pads of said chip. The encapsulant dispensed into the through-holes can flow from the surface of said chip to the edge thereof. Said package body has one portion provided within the through-hole of said substrate and another portion provided around the edge of said chip whereby encapsulation process is accomplished without having to turn the whole semiconductor package device.
