A method and an apparatus for smoothening rough edges of lithographic patterns on semiconductor wafers and thus improving quality of the elements that constitute the target pattern by softening the surface layer of the rough edges to the extent at which smoothening may occur under the effect of forces of surface tension. The pattern is treated under normal pressure in the atmosphere of a phase of the aforementioned organic substance selected from vapor of an organic vapor or mist of organic substance in nitrogen or another gas. Two modes are possible: 1) direct diffusion of organic molecules into the surface layer of the pattern material; or 2) condensation onto the pattern surface with the formation of an extremely thin organic film, which also leads to diffusion of the organic molecules into the pattern material.
