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. |
