Abstract:
A probe structure comprising:a first plate-like member having a plurality of probes formed on a main surface to test electrical characteristics of a subject under test, and secondary electrodes formed on an opposing surface of the main surface and electrically connected to corresponding probes; a second plate-like member arranged on the first plate-like member in a side of the secondary electrodes on the first plate-like member; the second plate-like member having first electrodes formed on a surface to correspond with the secondary electrodes of the first plate-like member, and secondary electrodes formed on an opposing surface and electrically connected to the corresponding first electrodes; a third plate-like member arranged on the second plate-like member in a side of the secondary electrodes of the second plate-like member; electrical connectors disposed between the second plate-like member and the third plate-like member and aligned with the corresponding secondary electrodes of the second plate-like member; and a fourth plate-like member arranged between the first plate-like member and the second plate-like member, to surround an area where the secondary electrodes of the first plate-like member are formed and to be connected with the first electrodes of the second plate-like member.
