Abstract
A method of depositing of a film on a substrate with controlled adhesion. The method comprises depositing the film including metal, wherein the metal is deposited on the substrate using physical vapor deposition at a pressure that achieves a pre-determined adhesion of the film to the substrate. The pre-determined adhesion allows processing of the film into a device while the film is adhered to the substrate but also allows removal of the device from the substrate.
