Abstract
A method of fabricating a semiconductor device, includes: removing, after forming solder for forming a plurality of bumps on a semiconductor substrate, an oxide film formed on a surface of the solder while heating the semiconductor substrate with first radiant heat; and heating the semiconductor substrate with an amount of second radiant heat that is greater than the amount of the first radiant heat by holding the semiconductor substrate at a position apart from a front surface of a heater stage at a predetermined distance to reflow the solder from which the oxide film is removed.
