Abstract
A device and a method of forming the same are disclosed. The device comprises a substrate and a thin film. The substrate is characterized by a first coefficient of thermal expansion. The thin film is attached to a surface of the substrate, and is characterized by a second coefficient of thermal expansion. The thin film includes first and second layers in states of compression, and a third layer in a state of tension, the third layer being positioned between the first and second layers. The thin film is in a net state of tension within a temperature range.
