In given paper various phenomena of ultrasound influence on physical characteristics of dislocation crystals of A 2 B 6 type (CdS, ZnS, Cd x Hg 1-x Te) and of dislocation-free crystals (Ge, Si) are systematized; results for light emitting structures (GaAs, GaAlAs, GaP) are given; possibilities of the active ultrasound use in microelectronics device technology are analyzed.Separately dynamic effects (in-situ) are considered. Possible mechanisms of sound induced effects and their applications are discussed. New technological techniques such as ultrasound processing, thermoacoustic efect annealing, ultrasound induced doping and so on find an industrial application. A considered aspect of physical and technological effects of ultrasound in semiconductors is proposed for further usage in Sensor electronics:
