摘要： A system for monitoring contamination level of effluent of an offline brush conditioning system includes a first set of reservoirs configured to collect first effluents from corresponding portions of a first brush and a second set of reservoirs configured to collect second effluents from corresponding portions of a second brush, and the first and second effluents are from a fluid used to condition the first and second brushes that are configured to clean a surface of a semiconductor wafer. An effluent contamination monitor is configured to monitor contamination levels of the first and second effluents, wherein the monitored contamination levels may provide feedback for use in the brush conditioning.

摘要： A method for the dressing of a multi-thread grinding worm by a dressing roll, wherein the grinding worm has at least two screw channels which are arranged parallel to another, which screw channels extend helically around an axis of the grinding worm and wherein the dressing roll has at least two adjacent dressing profiles which are arranged along an axis of the dressing roll, wherein the dressing profiles of the dressing roll are guided simultaneously through adjacent screw channels of the grinding worm during the dressing of the grinding worm. To improve the precision of the dressing the method includes the steps: a) execution of a first partial dressing process at which the dressing profiles of the dressing roll are guided simultaneously through first adjacent screw channels of the grinding worm; b) execution of at least one second partial dressing process at which the dressing profiles of the dressing roll are guided simultaneously through second adjacent screw channels of the grinding worm, wherein the second adjacent screw channels are, compared with step a), offset in the direction of the axis of the grinding worm by at least one screw channel of the grinding worm.

摘要： A machining apparatus has a frame carrying a headstock capable of gripping one end of an elongated workpiece and rotating the workpiece about a machining axis. A turntable support is spaced axially from the headstock on the frame. A tailstock carried on the support can be aligned with the machining axis in a machining position of the support. A machining drive is carried on the frame and itself carries a rotatable grinding disk engageable radially of the machining axis with the workpiece when the workpiece is engaged between the headstock and tailstock. A dressing tool carried on the support axially offset from the support axis and angularly offset about the support axis from the tailstock is engageable in a dressing position of the support with the grinding disk for dressing same in the dressing position with the workpiece engaged between the headstock and tailstock.

摘要： A CMP pad conditioner including: (a) a disk-shaped substrate having a working surface which is provided by one of its axially opposite end surfaces and which is to be brought into contact with the CMP pad; and (b) abrasive grains which are fixed to the working surface. The substrate includes a radially inner portion and a radially outer portion which is located radially outwardly of the radially inner portion. The working surface in the radially outer portion is inclined with respect to the working surface in the radially inner portion, such that a thickness of the radially outer portion as measured in an axial direction of the substrate is reduced as viewed in a direction away from an axis of the substrate toward a periphery of the substrate. A ratio of an outside diameter of the radially inner portion to an outside diameter of the substrate is 60-85%.

摘要： A tool, for dressing both the inside and outside working surfaces of cup-shaped abrasive wheels used for grinding gears, is disclosed along with methods and apparatus for using the tool. The working portion of the dressing tool has a cylindrical shape with an outside surface parallel to its axis of rotation and a top surface extending radially, to the axis of rotation. The apparatus orients the tool relative to the grinding wheel so that only the outer cylindrical surface of the tool is used to dress the inside working surface of the grinding wheel, while only the top surface of the tool is used to dress the outside working surface of the wheel. Formulas are provided for calculating the optimum radius of the cylindrical surface of the tool for providing substantially equal effective relative curvatures between the tool and each of the respective sides of the grinding wheel, thereby resulting in similar grinding characteristics being dressed into both the inside and outside working surfaces of the grinding wheel.
