In the paper first results of study of etching speed and RMS roughnesses depending on an incidence angle and energy of ions for Si and Cr/Sc materials are presented. Possibility of variation in parameters of etching process (the incidence angle, energy of ions and exposition time) allows to pick up the optimum mode providing high speed etching or the minimal development of a roughness of a surface.
