主权项 1. A method of manufacturing a bump, the method comprising: forming a bump on an electrode pad included on a semiconductor chip; and controlling a shape of the bump by: adjusting an amount of oxygen concentration in a reflow chamber to select between a first concentration within a first range of oxygen concentration and a second concentration within a second range of oxygen concentration lower than the first range of oxygen concentration, the second concentration being lower than the first concentration; andreflowing the bump formed on the semiconductor chip under an oxygen atmosphere having the selected oxygen concentration, andcontrolling the shape of the bump to have one of a globular shape or a planar shape based on the selected oxygen concentration.
