  • SELECTIVE WET ETCH COMPOSITION AND METHOD
    Publication number: 20230121639
    Abstract: A composition and method for etching molybdenum-containing film on a microelectronic device substrate is provided. A microelectronic device substrate is contacted with the composition of the invention for a time sufficient to at least partially remove the molybdenum-containing film. The composition comprises at least one oxidizing agent, at least one complexing agent, at least one cationic surfactant, and has a pH of from about 7.5 to about 13. The etchant composition selectively removes molybdenum at an etch rate of about 20 to 50 ?/minute at room temperature, with improved uniformity of removal.
