Abstract:
1. A method of releasing a patterned film, the method comprising the steps of, generating an ion beam of ions for generating a patterned film in a bulk material, focusing the ion beam toward a buried volume in the bulk material, annealing the bulk material for forming the patterned film, the patterned film being a chemical compound of the ions and the bulk material, and laser etching the bulk material about the patterned film to release the patterned film about the bulk material in the presence of a chemical etchant, the laser etching serving to heat the bulk material about the patterned film to a temperature at which the chemical etchant reacts with the bulk material for etching the bulk material for creating a cavity about the patterned film, the patterned film being a buried patterned film.
