Zusammenfassung: | PURPOSE: A probe type DLTS(Deep-Level Transient Spectroscopy) is provided to measure characteristics of a magnetodiode effectively by connecting an electrode pad and both terminals of a capacitance measuring machine. CONSTITUTION: A probe type DLTS(Deep-Level Transient Spectroscopy) includes a vacuum chamber(500), a sample support portion(510), a probe, a horizontal support stand(533) and a capacitance measuring machine. The vacuum chamber has a magnetodiode(600) exposing a node pad which is a sample to be measured. The sample support portion supports the magnetodiode in the vacuum chamber and changes temperature of the magnetodiode. The probe is connected electrically to the node pad of the magnetodiode by being induced into the vacuum chamber. The horizontal support stand supplies resistant force against expansion and contraction of the sample support portion according to changes of temperature by joining to a side surface of the sample support portion. The capacitance measuring machine is connected to the node pad of the magnetodiode with the probe to changes of capacitance of the sample. Thereby, time and effort for measuring the DLTS are reduced.
