Abstract:
1. A method of forming a reinforced tip for selectively passing current through a media device, the method comprising: providing a substrate; forming a tip structure within a first portion of the substrate; depositing a first metal material on the substrate; depositing a second metal material such that the second metal material is disposed over the tip structure; depositing a stabilization film over the first metal material; exposing the first metal material, the substrate, and the stabilization film to an elevated temperature to form a desired stress gradient in the first metal material; etching a second portion of the substrate such that the second portion is removed from beneath the second metal material and from beneath a portion of the first metal material, thereby releasing a mechanical structure connected with the tip; wherein a third portion of the substrate providing a reinforcing structure is retained beneath the second metal to form a reinforced tip; and etching the stabilization film so that the first metal material is deployed, thereby extending the tip away from the substrate due to the desired stress gradient in the first metal material.
