    Abstract: The present invention relates to the use of a composition comprising one or more ammonium salt(s) of one or more compounds selected from the group consisting of sulfobutanedioic acid diester(s), (sulfomethyl)-butanedioic acid diester(s), methyl-sulfobutanedioic acid diester(s), sulfoglutaric acid diester(s), and sulfotricarballic acid triester(s), for cleaning or rinsing a product comprising a substrate and supported thereon a patterned material layer having line-space structures with a line width of 50 nm and below. The invention also relates to a corresponding method of making a cleaned or rinsed product comprising a substrate and supported thereon a patterned material layer having line-space structures with a line width of 50 nm or below. The invention also relates to a solution with color of HAZEN number below 1000 and/or a turbidity in the range of from 0.08 to 10 NTU, wherein the solution comprises water and one or more ammonium salt(s) and optionally one or more organic solvent compounds. The invention also relates to a method of making a corresponding solution.

    Abstract: Described herein is a cleaning composition for post-etch or post-ash residue removal from the surface of a semiconductor substrate and a corresponding use of said cleaning composition. Further described is the use of said cleaning composition in combination with one or more oxidants, e.g. for oxidative etching or partial oxidative etching of a layer or mask, comprising or consisting of TiN, preferably in the presence of a tungsten material, on the surface of a semiconductor substrate, and/or for post-etch or post-ash residue removal from the surface of a semiconductor substrate. Moreover, it is described a wet-etch composition comprising the cleaning composition of the present invention and one or more oxidants, the use of said wet-etch composition for oxidative etching or partial oxidative etching of a layer or mask, comprising or consisting of TiN, preferably in the presence of a tungsten material, on the surface of a semiconductor substrate, and/or for post-etch or post-ash residue removal from the surface of a semiconductor substrate, a process for the manufacture of a semiconductor device from a semiconductor substrate using said wet-etch composition and a kit comprising the cleaning composition of the present invention and one or more oxidants. Furthermore, it is described the use of an imidazolidinethione in a composition for etching or partially etching of a layer or mask on the surface of a semiconductor substrate and/or for cleaning a semiconductor substrate.
