    摘要: Methods and apparatuses for electrochemically depositing a metal layer onto a substrate. An electrochemical deposition apparatus comprises a substrate holder assembly including a substrate chuck and a relatively soft cathode contact ring. The cathode contact ring comprises an inner portion and an outer portion, wherein the inner portion directly contacts the substrate. An anode is disposed in an electrolyte container. A power supply connects the substrate holder assembly and the anode.

    摘要: An improvement in a copper damascene process is disclosed. The improvement comprises the step of projecting an electron beam on to a chemical mechanically polished material surface having copper filled etched trenches at a known angle of incidence with respect to the material surface for a known period of time, the electron beam having a beamwidth substantially covering the material surface and a known intensity.
