The workshop describes laboratory work on chemistry and semiconductor technology . The manual is intended for studying the main methods of physicochemical research of condensed systems (DTA, Tensimetric methods, built P-T-X-diagrams , methods of microstructural analysis and microhardness) , Different from , Methods of synthesis, crystallization purification and cultivation of semiconducting compounds , and also introduces the main technological operations in the production of semiconductor devices (oxidation, diffusion, Epitaxy, etching). In each work, a theoretical introduction is given, diagrams of devices and equipment, methods of quantitative processing of experimental results are given.
