    摘要: A microelectronic substrate and method for removing adjacent conductive and nonconductive materials from a microelectronic substrate. In one embodiment, the microelectronic substrate includes a substrate material (such as borophosphosilicate glass) having an aperture with a conductive material (such as platinum) disposed in the aperture and a fill material (such as phosphosilicate glass) in the aperture adjacent to the conductive material. The fill material can have a hardness of about 0.04 GPa or higher, and a microelectronics structure, such as an electrode, can be disposed in the aperture, for example, after removing the fill material from the aperture. Portions of the conductive and fill material external to the aperture can be removed by chemically-mechanically polishing the fill material, recessing the fill material inwardly from the conductive material, and electrochemically-mechanically polishing the conductive material. The hard fill material can resist penetration by conductive particles, and recessing the fill material can provide for more complete removal of the conductive material external to the aperture.

    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: Method and apparatus for chemically, mechanically and/or electrolytically removing material from microelectronic substrates. A polishing medium for removing material can include a liquid carrier, an electrolyte disposed in the liquid carrier, and abrasives disposed in the liquid carrier, with the abrasives forming up to about 1% of the polishing liquid by weight. The polishing medium can further include a chelating agent. An electrical current can be selectively applied to the microelectronic substrate via the polishing liquid, and a downforce applied to the microelectronic substrate can be selected based on the level of current applied electrolytically to the microelectronic substrate. The microelectronic substrate can undergo an electrolytic and nonelectrolytic processing on the same polishing pad, or can be moved from one polishing pad to another while being supported by a single substrate carrier.
