Patent ID: 7523539

Claim:
A probe manufacturing method comprising the steps of: forming a recess corresponding to a flat surface shape of a desired probe having a thickness direction by a resist mask on a sacrificial layer formed on a base table; after depositing a probe material in said recess, within which said sacrificial layer is exposed, to form a probe made of said probe material over said base table via said sacrificial layer, removing said resist mask; removing said sacrificial layer by an etching process with a part of said sacrificial layer remaining; and detaching from said base table said probe held on said base table by said remaining part of said sacrificial layer, wherein, for forming an opening for control of said remaining part of said sacrificial layer in said etching process in said probe so as to let said opening pass through said probe in the thickness direction thereof, a hole-forming portion for said opening is formed in said resist mask to promote etching of said sacrificial layer in said etching process at an edge of said opening.
