Title: Probe apparatus applicable to a wafer level burn-in screening
Inventor: ISHIZAKA MASAAKI
IPC: H01L21/66
Filed: 2002-05-13
Abstract: PURPOSE: To provide the wafer level burn-in means of a wafer having pins much more than a conventional one. CONSTITUTION: When a space constituted of a pressure substrate 15, a wafer tray 31 and a seal ring 33 is evacuated by using a vacuum pump through vacuum valve 34, atmospheric pressure given to the pressure substrate 15 is transmitted to a wiring board 11. Since the area of the wiring board 14 is smaller than the pressure substrate 15, total pressure received by the whole pressure substrate 15 is intensively pressurized to the wafer whose area is similar to the wiring board 14. Uniform pressure is given to the wafer through first to fourth rubber materials 16 to 19 different in hardness. Thus, higher pressure per unit area can be applied compared with the conventional case, and wafer level burn-in is possible with respect to the wafer having the large number of pins.
