Abstract
A novel method of forming a released metal spring structure is described. In the method, a release layer including a blowing agent is deposited, usually printed, over portions of a substrate. A metal film is deposited over both the release layer and the substrate. The release layer is then heated such that the blowing agent decomposes releasing a portion of the metal film. The metal film curls out of the plane of the substrate to form a spring structure.
