Abstract

A method for fabricating a cantilever having a device surface, a tapered surface, and an end region includes providing a semiconductor substrate having a first side and a second side opposite to the first side and etching a predetermined portion of the second side to form a plurality of recesses in the second side. Each of the plurality of recesses comprises an etch termination surface. The method also includes anisotropically etching the etch termination surface to form the tapered surface of the cantilever and etching a predetermined portion of the device surface to release the end region of the cantilever.
