Researches and Applications of Microelectronic Materials and their Devices in the high-frequency Ultrasonic Fields

Abstract

This paper essay offers survey of the research and development of the applications of microelectronics in the high-frequency ultrasonic fields. Furthermore, it briefly gives microelectronics materials and processing, their high-frequency ultrasonic transducer, and amplifications of the high-frequency ultrasonics, etc. Finally, some problems of microelectronics in the high-frequency ultrasonic fields, especially piezoelectric semiconductor and its acoustoelectric effect which need further researches are pointed out.
