Modeling of Mechanical Influence of Double-Beam Laser on Single-Crystalline Silicon

Abstract: The results of finite-element modeling of controlled laser thermosplitting of crystalline silicon are presented. The case of treatment by two laser beam with wavelengths, namely 0.808 µm and 1.06 µm is studied. Calculations of the thermoelastic fields formed in a single-crystalline silicon wafer as a result of consecutive two-beam laser heating and action of coolant were performed for silicon crystalline orientations: (100), (110), (111). Modeling was performed for circular and U-shaped laser beams. The result… Show more

“…In contrast, the laser-induced thermal crack propagation is considered to be a promising process for silicon cutting [ 28 , 29 , 30 ]. This is because it has the advantage of avoiding these problems [ 31 , 32 , 33 ] and producing a good surface finish [ 34 , 35 ].…”
