The stress state of evaporated Ag films prepared on Ti underlayers before and after encapsulation process has been studied by x-ray diffraction using a `sin 2ψ' technique. A low tensile stress of approximately 61 MPa was measured in the as-deposited Ag films. The stress was caused by nonequilibrium growth during film deposition and resulted in a lattice tension state in the film plane and a lattice compression state along the film normal. Thermal mismatch stress was produced by the encapsulation process at 600 °C, but most of this stress relaxed during the cooling stage, and a residual tensile stress of approximately 320 MPa in the film plane was determined.
