The conductive coating generally includes magnesium. A product and an organic optoelectronic device produced according to the method are also provided. ## Claims ### Claim 1 A system for depositing a conductive coating on a surface of a substrate, the system comprising: an evaporation source for evaporating a source material, the source material including magnesium; a shadow mask defining an aperture, the shadow mask being arranged between the evaporation source and the substrate; wherein the evaporation source is configured to direct the evaporated source material towards the surface of the substrate, wherein an organic coating covers at least a portion of the shadow mask for inhibiting deposition of the source material on the shadow mask, while allowing passage of at least some of the evaporated source material through the aperture. ### Claim 2 (depends on 1) The system of claim 1, wherein the organic coating is disposed on a surface of the shadow mask proximal to the evaporation source. ### Claim 3 (depends on 1) The system of claim 1, wherein the organic coating covers at least the portion of the shadow mask defining the aperture. ### Claim 4 (depends on 1) The system of claim 1, wherein the source material includes substantially pure magnesium. ### Claim 5 (depends on 1) The system of claim 1, wherein the source material includes magnesium alloy. ### Claim 6 A method for depositing a conductive coating on a surface of a substrate, the method comprising: a) providing an evaporation source for evaporating a source material including magnesium towards the surface of the substrate; b) providing a shadow mask defining an aperture between the evaporation source and the substrate; and c) providing an organic coating covering at least a portion of the surface of the shadow mask for inhibiting deposition of the source material on the shadow mask, while allowing passage of at least some of the evaporated source material through the aperture. ### Claim 7 (depends on 6) The method of claim 6, wherein the organic coating is removed and reapplied. ### Claim 8 (depends on 6) The method of claim 6, wherein the organic coating is disposed on a surface of the shadow mask proximal to the evaporation source. ### Claim 9 (depends on 6) The method of claim 6, wherein the organic coating covers at least the portion of the shadow mask defining the aperture. ### Claim 10 (depends on 6) The method of claim 6, wherein the source material includes substantially pure magnesium. ### Claim 11 (depends on 6) The method of claim 6, wherein the source material includes magnesium alloy.
