Abstract:
Compositions useful for the selective removal by etching of silicon-germanium-containing materials relative to silicon-containing materials, from a microelectronic device having features containing these materials at a surface, the compositions containing hydrofluoric acid, acetic acid, hydrogen peroxide, and at least one additional acid that will improve performance as measured by one or more of an etching rate or selectivity and are tunable to achieve the required Si:Ge removal selectivity and etch rates.

Claim (Index 9):
The method of  claim 1 , wherein the etching composition comprises:\n from 0.1 to 10 parts by weight hydrogen fluoride, from 5 to 50 parts by weight dissolved acetic acid, from 2 to 40 parts by weight dissolved formic acid, from 0.1 to 10 parts by weight dissolved sulfuric acid, and from 10 to 35 parts by weight dissolved hydrogen peroxide, from 0 to 20 parts by weight dissolved lactic acid, per 100 parts by weight dissolved materials in the etching composition.
