Bright Spots in the Image of Silicon Vidicon

Abstract
The origin of bright spots in the images of silicon vidicon is studied by investigating the etching patterns of the vidicon targets. It is found that (1) the bright spots are caused by a leaky diode which has a stacking fault generated during the course of oxidation in the (111) plane, and (2) there are two causes for stacking fault, that is, residual mechanical strain on the surface of the silicon wafer and grown-in defects.
