Patent ID: 7875193

Claim:
A method for manufacturing a probe structure, comprising steps of: (a) forming a first mask layer pattern defining one or more probe beam regions on a substrate; (b) forming a second mask layer pattern including a window on the substrate and the first mask layer pattern, the window at least exposing one or more probe tip regions, each of the one or more probe tip regions being disposed at an end portion of each of the one or more probe beam regions; (c) etching the substrate exposed through the window to form the one or more probe tip regions; (d) removing the second mask layer pattern disposed on the substrate and the first mask layer pattern; (e) etching the substrate exposed through the first mask layer pattern to form the one or more probe beam regions; (f) removing the first mask layer pattern; and (g) filling the one or more probe beam regions and the one or more probe tip regions to form the probe structure.
