Shadow mask comprising a gravity-compensation layer and method of fabrication

Last updated:

Abstract:

A shadow mask that includes compensation layer operative for at least partially correcting gravity-induced sag of a shadow-mask membrane is disclosed. The compensation layer is formed on a surface of the shadow-mask membrane such that the compensation layer is characterized by a residual stress that gives rise to a first bending moment in the membrane, where the first bending moment is directed in the opposite direction to a second bending moment in the membrane that is induced by the effect of gravity.
