There is provided a method of manufacturing a substrate for flip chip, and a substrate for flip chip manufactured using the same. The method includes providing a base substrate including at least one conductive pad, forming a solder resist layer on the base substrate, the solder resist layer including a first opening exposing the conductive pad, forming a dry film on the solder resist layer, the dry film including a second opening connected with the first opening, forming a metal post in the first opening and a part of the second opening, filling the second opening above the metal post with solder paste, forming a solder cap by performing a reflow process on the filled solder paste, planarizing a surface of the solder cap, and removing the dry film. Accordingly, fine pitches and improve reliability can be achieved.
