Microelectronics is a field embodying the transfer, storage and processing of information. Thus microelectronics is the technical base of informatics. It encompasses the materials, properties and technological processes, through which a multitude of devices and principles of operation are realized. Microelectronics is naturally related to mathematics and physics. Mathematics provides the theoretical tools while physics delivers the necessary materials and processes. Following the material information carrier, microelectronic devices separate into semiconductor and wave. Semiconductor microelectronics still remains prominent in digital information processing. Wave microelectronics, on the other hand, demonstrates increased functionality and advantage in analog processing. With regard to information processing acoustic waves demonstrate a vital advantage over electromagnetic waves. Their propagation velocity in solid media is five orders of magnitude lower than light velocity. This means that, at one and the same frequency, the device dimension obeys the same proportionality ratio. Another important side is the efficiency of impact of the electric field on the acoustic parameters.
