| 20090029504 | WAFER-LEVEL ACA FLIP CHIP PACKAGE USING DOUBLE-LAYERED ACA/NCA - A method of manufacturing a wafer-level flip chip package is capable of being used to produce a flip chip package by directly coating a flip chip package using anisotropic conductive adhesives (ACA) and non conductive adhesives (NCA) in a solution state as a double layer on a wafer. The method can be used to manufacture a non-conductive mixed solution and a conductive mixed solution and directly coat them on a substrate, such that it is possible to: increase productivity; simplify a manufacturing process; suppress a shadow effect; easily perform thickness control that is difficult with the anisotropic conductive adhesive paste or the non-conductive adhesive paste; and obtain the non-conductive layer and the anisotropic conductive layer in an initial state of a B-stage with a level not losing latent of hardening through a simple drying process to volatilize an organic solvent. Above all, the non-conductive layer and the anisotropic conductive layer is sequentially stacked on the substrate formed with the non-solder bump, making it possible to make the selectivity of electrical conduction and the stability of a connection process excellent, shorten process time and costs, and dramatically reduce consumption of the conductive particles which account for a large portion of total production costs. | 01-29-2009 |
