Abstract:
A probe stylus for inspecting a semiconductor device, which contacts a pad disposed in a semiconductor device during an inspection of the semiconductor device, wherein the probe stylus comprises:a first electrically conductive member formed as a needle, a second electrically conductive member formed as a needle, and an insulating member arranged between the first electrically conductive member and the second electrically conductive member and connecting them so that the first and second electrically conductive members and the insulating member form a single needle, wherein a slit is disposed between the first and second electrically conductive members at their tip portion, where the probe stylus contacts with a pad disposed in a semiconductor device, the slit opens when the probe stylus contacts with a pad disposed in a semiconductor device so that the first and second electrically conductive members separate from each other in a lateral direction.
