METHOD OF MAKING HEAT TREATED COATED ARTICLE WITH CARBON BASED COATING AND PROTECTIVE FILM

摘要

A method of making a heat treated (HT) or heat treatable coated article. A method of making a coated article includes a step of heat treating a glass substrate coated with at least layer of or including carbon (e.g., diamond-like carbon (DLC)) and an overlying protective film thereon. In certain example embodiments, the protective film may be of or include both (a) an oxygen blocking or barrier layer, and (b) a release layer of or including zinc oxide. Treating the zinc oxide inclusive release layer with plasma including oxygen (e.g., via ion beam treatment) improves thermal stability and/or quality of the product. Following and/or during heat treatment (e.g., thermal tempering, or the like) the protective film may be entirely or partially removed.

1. A method of making a coated article, the method comprising:
depositing a release layer comprising zinc oxide on a glass substrate, wherein at least a layer comprising carbon is located between the glass substrate and the release layer comprising zinc oxide; ion beam treating the layer comprising zinc oxide with at least oxygen ions to provide an ion beam treated layer comprising zinc oxide; depositing an oxygen barrier layer on the glass substrate over the ion beam treated layer comprising zinc oxide; and wherein a protective film comprising the ion beam treated layer comprising zinc oxide and the oxygen barrier layer are for protecting the layer comprising carbon during subsequent heat treatment in order to prevent significant burnoff of the layer comprising carbon.
