发明名称 METHODS FOR FABRICATING INTEGRATED CIRCUITS USING CHEMICAL MECHANICAL PLANARIZATION TO RECESS METAL
摘要 Methods for fabricating integrated circuits using chemical mechanical planarization (CMP) for recessing metal are provided. In an embodiment, a method for fabricating an integrated circuit includes filling a trench with a metal and forming an overburden portion of the metal outside of the trench. The method further includes performing a planarization process with an etching slurry to remove the overburden portion of the metal and to recess the metal within the trench.
