Thermomechanical Relaxation of Thin-Film Metallizations
Published online by Cambridge University Press: 22 February 2011
Abstract
Pure Al and Cu films evaporated on thin glass and thermally oxidized silicon substrates are subject to changes in temperature Ṫ>100Ks-1. With constant temperature the stress relaxation is between 1 and 10 % of the thermally induced stress. The stationary creep rates are comparable to diffusion controlled power-law creep. The discontinuous grain growth during the T cycling shifts the transient amplitudes and the stationary slopes of stress to negative values. DC resistance measurements indicate the production and annihilation of vacancies.
