Abstract
Provided are a semiconductor element bonding apparatus and a semiconductor element bonding method that do not cause a bonding material to protrude and also ensure adhesion, even when there are variations in a thickness of a semiconductor element or a workpiece and even when there are projections and depressions on surfaces. A semiconductor element bonding apparatus includes disposing means for disposing a workpiece and a semiconductor element at positions facing each other, moving means for moving the workpiece or the semiconductor element in a vertical direction, displacement measuring means for measuring displacement of the workpiece or the semiconductor element in the vertical direction, load measuring means for measuring a contact load between the workpiece and the semiconductor element with the bonding material interposed therebetween, and elastic modulus calculating means for calculating an elastic modulus from results of the measurement by the displacement measuring means and the load measuring means.
