... of the electronic devices. Laser scanning localization with a test system utilizes the trigger or synchronous input of the microscope electronics shown in Fig. 10 : a functional pattern is executed and any local defect may cause a fail depending on the pattern. The tester evaluates the result (pass or fail) from...

.... The LSIM is actually an adaptation of a laser-scanning microscope (LSM). In the LSM, the injected laser light is scanned over a circuit in a raster pattern, and the reflection is detected and displayed. An LSM image appears much like any light microscope image. As can be seen in figure 36 , images...
