Abstract:
1. A method of selectively applying a ceramic coating to an object, comprising: (a) forming a layer of metal over the object; (b) forming a layer of photosensitive polyamide over the metal layer; (c) applying a mask over the object for exposing areas of the polyamide layer that are formed over portions of the metal layer where the ceramic layer is not to be applied; (d) exposing the object to radiation through the mask such that exposed areas of the polyamide layer are polymerized and unexposed areas of the polyamide layer remain unpolymerized; (e) removing the unpolymerized areas of the polyamide layer; (f) forming a layer of ceramic material over the object such that first portions of the ceramic layer are formed over the polymerized areas of the polyamide layer and second portions of the ceramic layer are formed over the metal layer; (g) scribing the first portions of the ceramic layer; (h) soaking the object in a solution for removing the first portions of the ceramic layer and the polymerized areas of the polyamide layer; and (i) removing the first portions of the ceramic layer and the polymerized areas of the polyamide layer.
