ABSTRACT:
A probe having a sufficient height is manufactured by selectively depositing, over the main surface of a wafer, a copper film in a region in which a metal film is to be formed and a region which will be outside an adhesion ring when a probe card is fabricated; forming the metal film, polyimide film, interconnect, another polyimide film, another interconnect and a further polyimide film; and then removing the wafer and copper film. According to the present invention, when probe testing is performed using a prober (thin film probe) having the probe formed in the above-described manner while utilizing the manufacturing technology of semiconductor integrated circuit devices, it is possible to prevent breakage of the prober and a wafer to be tested.
