Abstract
According to various exemplary embodiments, a spring device that includes a substrate, a self-releasing layer provided over the substrate and a stressed-metal layer provided over the self-releasing layer is disclosed, wherein an amount of stress inside the stressed-metal layer results in a peeling force that is higher than an adhesion force between the self-releasing layer and the stressed-metal layer. Moreover, a method of manufacturing a spring device, according to various exemplary embodiments, includes providing a substrate, providing a self-releasing layer over the substrate and providing a stressed-metal layer over the self-releasing layer wherein an amount of stress inside the stressed-metal layer results in a peeling force that is higher than an adhesion force between the self-releasing layer and the stressed-metal layer is also disclosed in this invention.
