Abstract:
A method of producing a chip scale package is disclosed. The method includes dicing a wafer into a plurality of chip arrays, each array including two or more integrated circuit chips. The method further includes mounting each array on a substrate and dicing each array, attached to the substrate, into individual chip scale packages, each individual chip scale package including only one integrated circuit chip.
Abstract:
A chip scale integrated circuit package includes an integrated circuit chip which has a first face and a second face. A plurality of pillar bumps are formed on the first face of the integrated circuit chip. An encapsulant material encapsulates the sides and the first face of the integrated circuit chip, and the pillar bumps. Upper ends of the pillar bumps remain free form encapsulant material and a substantially planar surface is formed by an upper surface of the encapsulant material and the upper ends of the pillar bumps. A plurality of solder balls are mounted on the substantially planar surface in locations corresponding to the upper ends of the pillar bumps.
Abstract:
A Wafer level stacked package (200), comprising a main silicon chip (101 ) having first face and second face and having plurality of dielectric and metal trace patterns on first (122) and second faces (126). The silicon chip having plurality of through silicon metal filled vias linking (130), the metal trace patterns of first and second faces of the main silicon chip. The silicon chip having plurality of bumps (140) at the first face. The silicon chip having a bottom encapsulant member (150) covering the first face and the bumps, with bump connections extended outside the encapsulant surface and with bottom encapsulant extending sideways and exactly equal to the size of the main silicon chip.
