Inventor: TANAKA HIROYUKI
IPC: G01R31/26
Filed: 1991-02-05
Abstract: PURPOSE:To obtain an apparatus which can detect a very small destroyed part by a method wherein the apparatus includes the following: a laser as a light source; a specific scanning mirror; a specific photodetector; a specific signal conversion part; and a specific external DC power supply. CONSTITUTION:The title apparatus includes the following: a laser 1 as a light source; a scanning mirror 2 which is used to scan the laser beam on the surface of a semiconductor device 8 to be tested; a photodetector 3 which detects reflected light 6 form the semiconductor device 8 to be tested; a signal conversion part 4 which coverts a detection signal SL into a video signal; and an external DC power supply 9 which applies a DC voltage to the semiconductor device 8 to be tested. Thereby, when the DC voltage is applied to the semiconductor device 8 from the external DC power supply 9, heat is generated locally at a destroyed part 7. Since a surface temperature at a locally heated part is high as compared with that in the circumference, a modulated optical reflection factor is changed. Consequently, when a laser beam 5 is scanned on the surface of the specimen and its reflected light 6 is measured, it is possible to detect a very small destroyed part.
