Title: Inspection method of semiconductor device
Inventor: FUJITO MANABU
IPC: H01L21/66
Filed: 1990-02-16
Abstract: PURPOSE:To enhance the efficiency and reliability regarding the judgment of a defective sample related to an impact ionization phenomenon by a method wherein a voltage displaying two peaks with reference to a substrate current against a gate voltage is applied to a drain and whether a transistor characteristic is good or not is judged on the basis of a substrate current value at the peak on the side where the gate voltage out of the two peaks is high. CONSTITUTION:A voltage displaying two peaks with reference to a substrate current against a gate voltage is applied to a drain. A substrate current value at the peak on the side where the gate voltage is high out of the two peaks is found. Whether a transistor characteristic is good or not is judged on the basis of the substrate current value. The peak on the side where the gate voltage is high is sensitive to the structure of a transistor such as the asymmetry of a source and a drain, the asymmetry of a channel width or the like, and is sensitive to a change in the crystallinity near the drain. In the region where the gate voltage is high, electrons by impact ionization are injected into a gate oxide film, and a deterioration phenomenon of the transistor characteristic such as a change in a threshold value or the like is caused. Thereby, the efficiency and reliability regarding the judgement of a sample related to an impact ionization phenomenon can be enhanced.
