Abstract:
A method of producing a layer having a structure in a form of at least one line having a submicrometer width, comprising the steps of:(a) providing a silicon support or a glass support as a substrate; (b) depositing a pure metal film on said substrate; (c) applying to said pure metal film a mask layer and structuring said mask layer so that an edge of the mask layer is formed along a location for said line, thereby forming a layer system consisting essentially of said substrate, said film and said layer; and (d) subjecting said layer system to a thermal treatment at a temperature and for a length of time sufficient to generate tension in said film to produce a tension-dependent separation in said film below said edge with a submicrometer width forming said line solely by the action of the temperature for the said time.
