    Abstract: 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.

    Abstract: A polishing head for polishing machines, in particular for polishing optical surfaces, has a polishing plate that is connected to a rotationally drivable drive shaft. The polishing plate is articulated to, and rotates with, the drive shaft. A ball hexagonal socket joint provides the articulated connection. Rotating by means of the articulated connection, the polishing plate can follow the surface of the workpiece to be processed, so that the polishing covering on the polishing plate always rests on a maximally large area on the surface of the workpiece.

    Abstract: Chemical mechanical polishing (CMP) systems and methods are provided herein. One aspect of the present subject matter is a polishing system. One polishing system embodiment includes a platen adapted to receive a wafer, and a polishing pad drum that has a cylindrical, or generally cylindrical, shape with a length and an axis of rotation along the length. The polishing pad drum is adapted to rotate about the axis of rotation along the drum length. The polishing pad drum, the platen, or both the polishing pad drum and the platen are adapted to be linearly moved to polish the surface of the wafer using the rotating polishing pad drum. The polishing pad drum and the platen are adapted to be operably positioned a predetermined minimum distance from each other as the polishing pad drum and the platen pass each other due the linear motion.

    Abstract: A controlled pressure regulation system generates the wafer-pressing pressures during a polishing operation. A wafer carrier head holds a wafer to be polished against a platen. A first and second pressure regulators respectively generate a first and second pressure onto the platen and the wafer carrier head to press the wafer to be polished. A first and second controllers are respectively connected to the first and second pressure regulators in control feedback loops to control the generation of the first and second pressures. The first and second pressures are controlled to obtain a desired difference of pressure between the first and second pressure.

    Abstract: The methods and systems described provide for an in-situ endpoint detection for material removal processes such as chemical mechanical processing (CMP) performed on a workpiece. In a preferred embodiment, an optical detection system is used to detect endpoint during the removal of planar conductive layers using CMP. An optically transparent polishing belt provides endpoint detection through any spot on the polishing belt. Once endpoint is detected, a signal can be used to terminate or alter a CMP process that has been previously initiated.

    Abstract: A lapping monitor for monitoring the lapping of a lapping surface of a body having at least one transducer which has a height that has to be lapped. The lapping monitor has a lap unit for lapping the lapping surface, at least one lapping indicator mounted close to the transducer to indicate the height of the transducer and a control block in the body at a certain distance from the lapping indicator or indicators. It is also possible to use a property of the transducers themselves, e.g., their resistance, to indicate their height. The control block receives indication of the height of the transducers being lapped from the lapping indicators or from the transducers via an electrical connection. The control block is further equipped with test contacts for establishing an external connection. The lapping monitor is particularly well-suited for performing 4-point resistance tests of the lapping indicators or transducers and can be effectively employed in lapping rows of magnetoresistive transducers such as MR or GMR heads to accurate heights.
