The evolution of integrated microelectronics products is inseparable from the progress in the field of integrated circuit enclosure technology , 10 to 15 years ago, it was classified as a minor ,. not requiring large-scale scientific research and based on the use of the capabilities of the existing fleet of assembly equipment. During this period, many significant problems in the field of microelectronics were solved. At the same time, there is a sharp increase in the interest of scientists and serial production specialists in the technology of housing modern products of integrated microelectronics - large integrated circuits (BIS) and ultra-large integrated circuits (SBIS) , in which the central place is occupied by micromontage of crystals. The book summarizes the results of theoretical and experimental studies of the physicochemical properties of thin films , applied to crystals, The basic elements of BIS housings and output frames are considered, details specified features of the technological process of micromontage of crystals, described the composition and features of the operation of the process equipment used in microassembly. The book is written in a simple and understandable language and will undoubtedly find recognition among microelectronics specialists, since publications on the presented profile are quite rare and very popular both in the domestic press and abroad.
