The laser gettering of silicon wafers is experimentally investigated. The typical gettering parameters are considered. The surfaces of laser-treated silicon wafers are investigated by microscopy. When studying the effect of laser radiation on silicon wafers during gettering, a group of factors determining the conditions of interaction between the laser beam and silicon-wafer surface and affecting the final result of treatment are selected. The main factors determining the gettering efficiency are revealed. Limitations on the desired value of the getter-layer capacity on surfaces with insufficiently high cleanness (for example, ground or matte) are established.
