Abstract: PURPOSE:To assure the evaluation of dopant concentration and the measurement of a crystal effect by measuring the maximum length of dislocation around a dent formed by etching with molten KOH after pressing a contactor against a GaAs wafer (100) plane. CONSTITUTION:A dent 1 is formed on a polished GaAs wafer (100) plane by pressing diamond contactor of a microivickers hardness meter gainst that plane. Then, once the GaAs wafer surface including the dent is etched with molten KOH, an etching pit corresponding to dislocation, i.e., alpha dislocation 2 and betadislocation 3 appear. Hereby, dopant concentration can be estimated by measuring the maximum length l of the dislocation formed on the GaAs wafer (100) plane, i.e., the length of the alpha dislocation 2. Further, if the kind and concentration of the dopant are known, a low dislocation change by the dopant, i.e., the effect of hardened crystal can quantitatively be measured by measuring the maximum length of dislocation distribution.
