Abstract

A method for the measurement of semiconductor polarization losses in the depletion region of a finished diode is considered. It is shown that the measurement can be performed by comparing with a low-loss capacitor using general-purpose impedance meters in laboratories without stabilizing the microclimate and shielding the electromagnetic fields. To exclude the drift error under these conditions, multiple regular switching of the measurement object and low-loss capacitor is proposed. As a result, the polarization loss tangent of 1.9 × 10⁻⁴ was measured with an error of ±16%.

成品二极管中半导体材料低极化损耗的测量

研究了一种测量成品二极管损耗区半导体极化损耗的方法。实验结果表明，在不稳定小气候和屏蔽电磁场的情况下，使用通用阻抗仪与低损耗电容进行比较，可以实现测量。为了消除这种情况下的漂移误差，提出了测量对象与低损耗电容的多次规则开关。测量的偏振损耗正切值为1.9 × 10−4，误差为±16%。
