Abstract
A method of forming, on the surface of a glass material, a raised feature having a height within a target range, comprising (1) providing a glass material having a surface, (2) providing the glass material locally, at a location at or below the surface, with an amount of energy causing local expansion of the glass material so as to raise a feature on the surface at the location, (3) detecting the height of the raised feature or the height over time of the raised feature, (4) (a) if the height is below or approaching a value below the target range, providing the glass material at the location with energy in a greater amount, or (b) if the height is above or approaching a value above the target range, providing the glass material at the location with energy in a lesser amount, and (5) repeating steps (3) and (4) as needed to bring the height within the target range. Methods and devices for automating this process are also disclosed.
