Abstract:
1. A method for manufacturing a probe structure, the method comprising steps of: (a) forming a first mask layer pattern defining a probe beam region on a semiconductor substrate; (b) forming a second mask layer pattern defining a probe tip region on the semiconductor substrate and the first mask layer pattern; (c) etching the semiconductor substrate using the second mask layer pattern as an etching mask to form the probe tip region; (d) removing the second mask layer pattern; (e) etching the semiconductor substrate using the first mask layer pattern as the etching mask to form the probe beam region; (f) forming a sidewall insulating film pattern on a sidewall of each of the probe tip region and the probe beam region; (g) etching a predetermined thickness of a portion of the semiconductor substrate exposed by the first mask layer pattern; (h) removing the sidewall insulating film pattern and the first mask layer pattern; and (i) forming a probe tip and a probe beam in the probe tip region and the probe beam region.
