| 20080290888 | PROBE SUBSTRATE FOR TEST AND MANUFACTURING METHOD THEREOF - A probe substrate includes a probe having a plurality of beams and a contactor formed at one end of the beam, and a support substrate for supporting the probe and having a bending space in which the probe moves upwards and downwards. The beam and the contactor are made of the same metal, and the sidewall of the contactor has a staircase configuration. Therefore, the probe substrate and the manufacturing method thereof repeats the lithographic process and the plating process to form the probe having the beam and the contactor combined, thereby increasing the bending degree and structural stability of the probe. | 11-27-2008 |
