Flip chip for electrical function test and manufacturing method thereof
Abstract:
Disclosed is a method for manufacturing a flip chip, in which a gold typically used in a flip chip manufacturing is adhered by conductive adhesives, wherein the method comprises steps of depositing a metal seed layer on a substrate; applying and patterning a photoresist or a dry film; forming a gold bump by electroplating; patterning the seed layer; forming an insulating layer on the seed layer and upper end of the gold bump; and patterning an insulating layer. Accordingly, it is possible to manufacture a flip chip, in which electrical function between bumps can be evaluated, with less cost.
