随着现代电子工业的迅猛发展,高可靠己成为现代武器系统、军用电子设备、航天航空工程和高性能电子整机的基本要求,电子整机、设备和系统要求能够在各种条件下工作,这就对半导体器件提出了具有耐环境变化的高可靠性和高稳定性的要求.半导体器件的电特性参数大多是温度敏感参数,环境温度的高低温变化将引起半导体器件电性能的剧烈变化,这直接影响了电子整机、设备和系统的性能,甚至使它们丧失工作能力.
With the rapid development of modern electronic industry, high reliability has become the basic requirement of modern weapon system, military electronic equipment, aerospace engineering and high-performance electronic complete machine. Electronic complete machine, equipment and system requirements can work in various conditions, This puts forward the requirements of semiconductor devices with high reliability and high stability against environmental changes.The electrical characteristics of semiconductor devices are mostly temperature-sensitive parameters, high and low ambient temperature changes will cause drastic changes in the electrical properties of semiconductor devices, This has a direct impact on the performance of electronic machines, equipment and systems, even making them incapacitated.
