A flip chip package structure and manufacturing method thereof is provided. A chip is electrically connected to a substrate. A heat sink is attached to the backside of the chip. The heat sink has at least a through hole located at a peripheral region and laterally adjacent to the chip. A dispensing process is carried out to deliver an underfill material via the through hole such that the space between the chip and the substrate is filled. The underfill material also extends to cover a portion of the heat sink so that the heat sink and the substrate are connected together. The underfill material is cured to fix the heat sink, the substrate and the chip in position.

The present invention relates to a method for flip chip bonding by utilizing an interposer with embedded bumps. The method comprises (a) providing a first element having a first surface; (b) forming an interposer onto the first surface; (c) forming a plurality of openings on the interposer; (d) forming a plurality of bumps in the openings, wherein the height of the bumps is smaller than the depth of the openings; (e) providing a second element having a plurality of pre-solders; and (f) bonding the first surface onto the second element, so that the pre-solders are disposed in the openings and in contact with the bumps. As a result, the self-alignment between the pre-solders and the bumps can avoid the shift between the first element and the second element.
摘要:
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.
