Abstract:
1. A method for producing an apparatus including a micro spring structure, the method comprising: forming a spring island over a substrate such that the spring island has a stress gradient; forming a second layer of release material over a first portion of the spring island; forming a base structure over the second layer of release material and a second portion of the spring island; forming a base structure over the second layer of release material and a second portion of the spring island, thereby completing an unreleased spring structure including the substrate, the spring island, the second layer of release material, and the base structure; mounting the unreleased spring structure onto the apparatus by securing the base structure to the apparatus such that the spring island is located between the apparatus and the substrate; and removing the substrate and releasing the second portion of the spring island by removing the second layer of release material.
