The results of the investigation of stress relaxation by strain by means of EPR spectra, IR absorption spectra, SEM and samples deflection are presented. It has been shown that stress relaxation mechanisms depend on the oxidation conditions: temperature, cooling rate, oxide thickness. In the Si- SiO2-Si3N4 system the stress relaxation by strain occur due to the opposite sign of the thermal expansion coefficient of Si-SiO2 and Si3N4 on Si. Laser irradiation allows to modify the system stresses.
