A method of making a heat treated (HT) coated article to be used in shower door applications, window applications, or any other suitable applications where transparent coated articles are desired. For example, certain embodiments of this invention relate to a method of making a coated article including a step of heat treating a glass substrate coated with at least a layer of or including carbon and an overlying protective film including a zinc oxide inclusive layer. Following and/or during heat treatment (e.g., thermal tempering, or the like) the protective film may be removed. Other embodiments of this invention relate to the pre-HT coated article, or the post-HT coated article.

1. A method of making a heat treated coated article, the method comprising: providing a glass substrate;forming at least one layer comprising carbon on the glass substrate;forming a removable protective film on the glass substrate over at least the layer comprising carbon, the removable protective film comprising a first layer comprising zinc oxide and a second layer comprising zinc oxide, wherein the first layer comprising zinc oxide is mor e metallic than is the second layer comprising zinc oxide, and wherein the first layer comprising zinc oxide is between the layer comprising carbon and the second layer comprising zinc oxide;heat treating the glass substrate with the layer comprising carbon and the protective film thereon so that during the heat treating the protective film prevents significant burnoff of the layer comprising carbon, wherein the heat treating comprises heating the glass substrate to temperature(s) sufficient for thermal tempering, heat strengthening, and/or heat bending; andremoving at least part of the protective film comprising zinc during and/or after said heat treating. 2. The method of claim 1, wherein the removable protective film is formed on the glass substrate via sputtering. 3. The method of claim 1, further comprising forming a barrier layer comprising silicon oxide and/or silicon nitride on the glass substrate so as to be located between at least the glass substrate and the layer comprising carbon. 4. The method of claim 1, wherein the heat treating comprises heating the glass substrate with the layer comprising carbon and the protective film thereon using at least temperature(s) of at least 580 degrees C. 5. The method of claim 1, wherein the layer comprising carbon comprises DLC. 6. A method of making a heat treated coated article, the method comprising: providing a glass substrate;forming at least one layer comprising carbon on the glass substrate;forming a removable protective film on the glass substrate over at least the layer comprising carbon, the removable protective film comprising first and second inorganic layers, the first inorganic layer comprising zinc oxide and being located between the layer comprising DLC and the second inorganic layer;heat treating the glass substrate with the layer comprising carbon and the protective film thereon so that during the heat treating the protective film prevents significant burnoff of the layer comprising DLC, wherein the heat treating comprises heating the glass substrate to temperature(s) sufficient for thermal tempering, heat strengthening, and/or heat bending, and wherein the first inorganic layer comprising zinc oxide and the second inorganic layer substantially remain on the glass substrate protecting the layer comprising DLC during said heat treating; andremoving the first inorganic layer comprising zinc oxide and the second inorganic layer after said heat treating. 7. The method of claim 6, wherein the heat treating comprises heating the glass substrate with the layer comprising carbon and the protective film thereon using at least temperature(s) of at least 580 degrees C. 8. A method of making a heat treated coated article, the method comprising: having a coated glass substrate comprising a layer comprising carbon and a removable protective film on the glass substrate over at least the layer comprising carbon, the removable protective film comprising a first layer comprising zinc oxide and a second layer comprising zinc oxide, wherein the first layer comprising zinc oxide is more metallic than is the second layer comprising zinc oxide, and wherein the first layer comprising zinc oxide is between the layer comprising carbon and the second layer comprising zinc oxide;heat treating the glass substrate with the layer comprising carbon and the protective film thereon so that during the heat treating the protective film prevents significant burnoff of the layer comprising carbon, wherein the heat treating comprises heating the glass substrate to temperature(s) sufficient for thermal tempering, heat strengthening, and/or heat bending; andremoving at least part of the protective film comprising zinc during and/or after said heat treating. 9. The method of claim 8, further comprising forming the removable protective film on the glass substrate via sputtering. 10. The method of claim 8, further comprising forming a barrier layer comprising silicon oxide and/or silicon nitride on the glass substrate so as to be located between at least the glass substrate and the layer comprising carbon. 11. The method of claim 8, wherein the heat treating comprises heating the glass substrate with the layer comprising carbon and the protective film thereon using at least temperature(s) of at least 580 degrees C. 12. The method of claim 8, wherein said removing comprises exposing the protective film to a solution comprising water to help said removing. 13. The method of claim 8, wherein said removing comprises exposing the protective film to a solution comprising vinegar to help said removing.
