Abstract

In this paper, bonded wafer analysis system is proposed using laser beam transmission; while the transmission model is derived by simulation. Since the failure of bonded wafer stems in void existence, transmittance deviations caused by the thickness of the void are analyzed and variations of the intensity through the void or defect easily have been recognized then the testing power has been increased. In addition, large screen display on laser study has been done which resulted in acquiring a feasible technique for analysis of the whole bonding surface. In this regard, three approaches are demonstrated in which Halogen lamp, IR lamp and laser have been tested and subsequently by results comparison the optimized technique using laser has been derived.
