Patent ID: 7721429

Claim:
A probe manufacturing method comprising the steps of: forming on a sacrificial layer on a base table a recess exposing said sacrificial layer with a resist; depositing a probe material in said recess to form a probe and then removing said resist; leaving part of said sacrificial layer and removing the rest by an etching process; and detaching from said base table said probe held on said base table by said remaining part of said sacrificial layer, wherein in said recess of said resist are formed a main body part corresponding to a flat surface shape of said probe and an auxiliary part continuing into said main body part and formed in a flat surface shape sufficient for a sacrificial layer part under a holding portion made of said probe material deposited at said auxiliary part to remain when a sacrificial layer part under said probe made of said probe material deposited at said main body part is removed by said etching process, and after said probe material is deposited in said recess including said auxiliary part, said probe is separated from said holding portion after removing said sacrificial layer part under said probe completely and before removing said sacrificial layer part under said holding portion completely by said etching process.
