Patent ID: 8381392

Claim:
A method, comprising: depositing a layer of pole material onto a base portion of a wafer, the layer of pole material having a first surface adjacent to the base portion and a second surface opposite the first surface; depositing a pattern of masking material onto a portion of the second surface of the layer; and removing material from the layer of pole material, including the pole material unprotected by the pattern of masking material, to form a pole comprising: a proximal end having a proximal surface and a distal end having a distal surface that is opposite the proximal surface, the distal surface connects the first surface and the second surface; a first portion, at the proximal end, that is suspended from the base portion of the wafer; and a second portion that includes the distal end, the second portion is connected to the first portion and the second portion is in contact with the base portion of the wafer.
