摘要：肖特基二极管具有开关频率高和正向压降低等优点，在低压、大电流输出场合常被用作高频整流，在高频下用于检波和混频，在高速逻辑电路中用作箝位，在IC中也常使用SBD，如SBD-TTL集成电路早已成为TTL电路的主流，在高速计算机中被广泛采用。SBD是利用金属与半导体接触形成的金属-半导体势垒制成的，因此，它是一种热电子发射二极管，随着制造工艺的不断完善及特殊材料的出现，肖特基势垒栅FET及其高速大规模集成电路(LSI)和超大规模集成电路(VLSI)领域的广泛应用，肖特基二极管的应用范围也越来越广。

Abstract: Schottky diodes with a high switching frequency and positive pressure to reduce the advantages of the low-pressure, high current output high-frequency occasions are often used as high-frequency, high frequency used for detection and mixing, in the high-speed logic circuits used to clamp，The IC also frequently used in the SBD, such as the SBD-TTL IC TTL circuit has become the mainstream in high-speed computers are widely used in. SBD is the use of metal and semiconductor contact with the formation of metal - semiconductor barrier made of, so it is a thermal emission diode, with the manufacturing process of continuous improvement and the emergence of special materials, Schottky barrier gate and high-speed FET Large-scale integrated circuit (LSI) and ultra-large-scale integrated circuits (VLSI) wide field of applications, Schottky diodes on the application of more and more widely.

KEY WORDS: Schottky diodes  high-frequency   the manufacturing process
