Patent ID: 7119557

Claim:
A method of manufacturing a hollow microprobe using an MEMS technique, comprising: a step of forming a through hole 14 in a substrate 10 ; a step of forming a buried conductor 18 in the through hole 14 ; a step of planarizing a surface of the substrate 10 provided with the buried conductor 18 ; a step of forming a base conductive film 20 on the substrate 10 ; a step of forming a first tip supporter 22 , which has a oblique surface sloping down, on the substrate 10 provided with the base conductive film 20 ; a step of rounding the top surface of the first tip supporter 22 by eroding angled portions of the top surface of the first tip supporter 22 ; a step of forming a second tip supporter 24 on an outer surface of the first tip supporter 22 to allow the top surface of the first tip supporter 22 to be opened; a step of forming a tip 26 on the outer surface of the second tip supporter 24 ; and a step of removing a part of the top surface of the first tip supporter 22 opened by the second tip supporter and the tip by a predetermined depth.
