摘要： An electro-optical inspection apparatus prevents adhesion of dust or particles to a sample surface, wherein a stage on which a sample is placed is disposed inside a vacuum chamber that can be evacuated, and a dust collecting electrode is disposed to surround a periphery of the sample. The dust collecting electrode is applied with a voltage having the same polarity as a voltage applied to the sample and an absolute value that is the same or larger than an absolute value of the voltage. Because dust or particles adhere to the dust collecting electrode, adhesion of the dust or particles to the sample surface can be reduced. Instead of using the dust collecting electrode, it is possible to form a recess on a wall of the vacuum chamber, or to dispose on the wall a metal plate having a mesh structure to which a predetermined voltage is applied.

摘要： A substrate polishing apparatus wherein a semiconductor substrate is held by a top ring 10-2 or 11-2 and is pressed against a polishing surface of a polishing table 10-1 or 10-2. A surface to be polished of the semiconductor substrate is polished by a relative movement between the semiconductor substrate and the polishing surface. The apparatus includes a pressing force changing mechanism for changing a pressing force for pressing the semiconductor substrate, a relative movement seed changing mechanism for changing the number of revolutions of the top ring and/or the polishing table, and a control mechanism. The control mechanism performs the polishing through plural polishing processes on the polishing table 10-1 or 10-2 while changing the pressing force and the number of revolutions.

摘要： A method for polishing a substrate having a metal film thereon is described. The substrate has metal interconnects formed from part of the metal film. The polishing method includes performing a first polishing process of removing the metal film, after the first polishing process, performing a second polishing process of removing the barrier film, after the second polishing process, performing a third polishing process of polishing the insulating film. During the second polishing process and the third polishing process, a polishing state of the substrate is monitored with an eddy current sensor, and the third polishing process is terminated when an output signal of the eddy current sensor reaches a predetermined threshold.

摘要： A method and apparatus for polishing a workpiece are set forth which can polish the workpiece at a constant rate at a stable condition even when plural workpieces are continually polished. The method comprises dressing a polishing surface of a polishing table while supplying a dressing solution. After the dressing, the dressing solution remaining on the polishing surface is removed by rotating the polishing table at a dewatering rotation speed while stopping the supply of the dressing solution. Then, the workpiece is polished by making the workpiece slidingly contact with the polishing surface while supplying a polishing solution to the polishing surface.

摘要： A semiconductor substrate having a Cu layer formed so as to fill wiring grooves formed in the substrate surface and to cover regions of the substrate surface where no wiring groove is formed is brought into sliding contact with a polishing surface on a turntable to carry out polishing until the Cu layer is polished to a predetermined thickness. Then, the semiconductor substrate is brought into sliding contact with a polishing surface on a turntable to carry out polishing until the Cu layer on the substrate surface is removed, except for portions of the Cu layer formed to fill the wiring grooves, and a barrier metal layer is also removed. Thus, the Cu layer on the substrate surface can be removed uniformly, and the Cu wiring portions formed in the wiring grooves can be planarly and uniformly polished without giving rise to problems of over-polishing such as dishing or erosion.
