摘要： Methods and apparatuses for selectively removing conductive materials from a microelectronic substrate. A method in accordance with an embodiment of the invention includes positioning the microelectronic substrate proximate to and spaced apart from an electrode pair that includes a first electrode and a second electrode spaced apart from the first electrode. An electrolytic liquid can be directed through a first flow passage to an interface region between the microelectronic substrate and the electrode pair. A varying electrical signal can be passed through the electrode pair and the electrolytic liquid to remove conductive material from the microelectronic substrate. The electrolytic liquid can be removed through a second flow passage proximate to the first flow passage and the electrode pair.

摘要： Methods and apparatuses for electromechanically and/or electrochemically-mechanically removing conductive material from a microelectronic substrate. An apparatus in accordance with one embodiment includes a support member configured to releasably carry a microelectronic substrate and first and second electrodes spaced apart from each other and from the microelectronic substrate. A polishing medium is positioned between the electrodes and the support member and has a polishing surface positioned to contact the microelectronic substrate. At least a portion of the first and second electrodes can be recessed from the polishing surface. A liquid, such as an electrolytic liquid, can be provided in the recess, for example, through flow passages in the electrodes and/or the polishing medium. A variable electrical signal is passed from at least one of the electrodes, through the electrolyte and to the microelectronic substrate to remove material from the substrate.

摘要： Methods and apparatuses for detecting characteristics of a microelectronic substrate. A method in accordance with an embodiment of the invention includes positioning the microelectronic substrate proximate to and spaced apart from the first and second spaced apart electrodes, contacting the microelectronic substrate with a polishing surface of a polishing medium, removing conductive material from the microelectronic substrate by moving the substrate and/or the electrodes relative to each other while passing a variable electrical signal through the electrodes and the substrate, and detecting a change in the variable electrical signal or a supplemental electrical signal passing through the microelectronic substrate. The rate at which material is removed from the microelectronic substrate can be changed based at least in part on the change in the electrical signal.

摘要： Methods and apparatuses for electrochemical-mechanical processing of microelectronic workpieces. One embodiment of an electrochemical processing apparatus in accordance with the invention comprises a workpiece holder configured to receive a microelectronic workpiece, a workpiece electrode, a first remote electrode, and a second remote electrode. The workpiece electrode is configured to contact a processing side of the workpiece when the workpiece is received in the workpiece holder. The first and second remote electrodes are spaced apart from the workpiece holder. The apparatus can also include an AC power supply, a DC power supply, and a switching assembly. The switching assembly is coupled to the workpiece electrode, the first remote electrode, the second remote electrode, the AC power supply, and the DC power supply. In operation, the switching assembly couples the AC power supply and/or the DC power supply to the workpiece electrode, the first remote electrode, and/or the second remote electrode for plating, deplating and/or mechanically removing material.
