    摘要: The present disclosure provides a method of fabricating a semiconductor device, a semiconductor device fabricated by such a method, and a chemical mechanical polishing (CMP) tool for performing such a method. In one embodiment, a method of fabricating a semiconductor device includes providing an integrated circuit (IC) wafer including a metal conductor in a trench of a dielectric layer over a substrate, and performing a chemical mechanical polishing (CMP) process to planarize the metal conductor and the dielectric layer. The method further includes cleaning the planarized metal conductor and dielectric layer to remove residue from the CMP process, rinsing the cleaned metal conductor and dielectric layer with an alcohol, and drying the rinsed metal conductor and dielectric layer in an inert gas environment.

    摘要: Methods for improving post etch in via or trench formation in semiconductor devices. A preferred embodiment comprises forming a re-capping layer over a dielectric film following an initial etch to form a feature in the dielectric film, followed by additional etch and etch back processing steps. The re-capping method provides protection for underlying films and prevents film damage post etch. Uniform feature profiles are maintained and critical dimension uniformity is obtained by use of the methods of the invention. The time dependent dielectric breakdown performance is increased.
