Abstract: PROBLEM TO BE SOLVED: To evaluate defective bonding in facedown mounting (surface mounting type) semiconductor device where the surface side of a semiconductor chip is connected with a mounting substrate. SOLUTION: When a semiconductor chip 10 is composed of a transparent material similar to a light-emitting diode 1 made by forming gallium nitride based compound semiconductor layers 12 and 13 on a transparent sapphire substrate 11, grains 30 composed of a material harder than that of electrodes 15 and 16 are stuck to the abutting portion of a gold bump electrode 21 in the electrodes 15 and 16 formed on the surface of the semiconductor chip 10. Consequently, the junction of the electrodes 15, 16 and the gold bump electrode 21 can be evaluated from whether the grains 30 can be confirmed visually from the rear surface of the semiconductor chip 10. Consequently, chips of defective junction can be screened and forming conditions or bonding conditions of the bump electrode can be adjusted appropriately from the evaluation results.
