人们常常把半导体电路不稳定的原因归结为我国半导体元件的质量。根据我们的经验这并不完全正确,虽然半导体电路的可靠性与半导体元件的质量有很大关系,但更重要的是设计人员对它要有一个清楚的认识。本文分析了半导体电路不可靠的原因,并提出正确处理电路中的接触问题和防止干扰是保证电路可靠地工作的关键。 People often put the semiconductor circuit instability due to the quality of our semiconductor components. According to our experience, this is not entirely correct. Although the reliability of semiconductor circuits has a lot to do with the quality of semiconductor components, it is even more important for designers to have a clear understanding of it. This paper analyzes the reasons for the unreliability of the semiconductor circuits and points out that the proper handling of the contact problems in the circuits and the prevention of interference are the keys to ensuring that the circuits operate reliably.
