Abstract: An electroplating bump in which solder is coated and a flip chip bonding method using the same are provided to directly bond bumps by using a liquid diffusion bonding method, thereby reducing a manufacturing cost and improving bonding strength and signal transmission capability. A conductive thin film(18) is formed on a substrate(10). A photoresist or a dry film is formed at an upper part of the conductive thin film as excluding a location in which a bump(14) will be formed. By using electroplating or electroless plating or sputtering or evaporation, the bump is formed on the conductive thin film. A solder less than 0.5 micro meter is formed on the bump by using the electroplating or electroless plating or sputtering or the evaporation. The height of the photoresist or dry film is greater than the height of the bump. The solder is made of tin or tin alloy in which a melting point is 450°C or less.
