Patent ID: 7344908

Claim:
A method for manufacturing an AFM (atomic force microscope) cantilever including an FET (filed effect transistor), the method comprising the steps of: a first step of forming a multi-layer insulating layer on a top of a substrate where an inter-layer insulating layer and a second semiconductor substrate are sequentially formed on a top of a first semiconductor substrate; a second step of, after the multi-layer insulating layer is sequentially etched, forming a source/drain and a channel by injecting other type ions different from a type of the second semiconductor substrate; a third step of forming a probe and a probe member by etching the second semiconductor substrate; a fourth step of, after an insulating layer is formed on an area except for the probe and the probe member, forming a metal electrode on top surfaces of source/drain and channel regions, respectively; a fifth step of forming a cantilever member by sequentially etching the remaining multi-layer insulating layer, the second semiconductor substrate, the insulating layer and the first semiconductor substrate; and a sixth step of forming a handling member by etching a rear surface of the first semiconductor substrate.
