Abstract: Shadow masks comprising a multi-layer membrane having a mechanical pre-bias that compensates the effect of gravity on the membrane are disclosed. A shadow mask in accordance with the present disclosure includes a membrane that is patterned with a desired pattern of apertures. The layers of the membrane are selected such that their residual stresses collectively give rise to a stress gradient that is directed normal to the plane of the membrane such that the stress gradient mitigates gravity-induced sag. In some embodiments, the membrane includes a layer pair having internal stresses that are of opposite signs to effect a tendency to bulge outward from the plane of the membrane prior to its release from the substrate. An exemplary membrane includes a layer pair comprising a layer of stoichiometric silicon dioxide that is under residual compressive stress and a layer of stoichiometric silicon nitride that is under residual tensile stress.
