    摘要: A chemical-mechanical polishing (CMP) control system controls distribution of pressure across the backside of a semiconductor wafer being polished. The system includes a CMP apparatus having a carrier for supporting a semiconductor wafer. The carrier includes a plurality of dual function piezoelectric actuators. The actuators sense pressure variations across the semiconductor wafer and are individually controllable. A control is connected to the actuators for monitoring sensed pressure variations and controlling the actuators to provide a controlled pressure distribution across the semiconductor wafer.

    摘要: An in-situ method for regenerating a chemical-mechanical polishing pad which includes the steps of: forming the polishing pad by dispensing liquid moldable material, such as wax, polymers or water, on a polishing surface and solidifying the liquid material by reducing the temperature, allowing the moldable material to harden; distributing slurry material on the polishing pad; polishing the surface of a semiconductor wafer with a combination of the slurry material and the polishing pad; and regenerating in-situ the polishing pad. This method quickly, easily and repeatably, resurfaces and refreshes the surface on which the a semiconductor wafer is polished. The polishing pad may also include abrasives embedded therein to enhance its polishing capabilities.

    摘要: Grooves are formed in a CMP pad by positioning the pad on a supporting surface with a working surface of the pad in spaced relation opposite to a router bit and at least one projecting stop member adjacent to the router bit, an outer end portion of the bit projecting beyond the stop. When the bit is rotated, relative axial movement between the bit and the pad causes the outer end portion of the bit to cut an initial recess in the pad. Relative lateral movement between the rotating bit and the pad then forms a groove which extends laterally away from the recess and has a depth substantially the same as that of the recess. The depths of the initial recess and the groove are limited by applying a vacuum to the working surface of the pad to keep it in contact with the stop member(s). Different lateral movements between the bit and the pad are used to form a variety of groove patterns, the depths of which are precisely controlled by the stop member(s). The grooves may be formed in the polishing surface and/or the rear opposite surface of the pad and passages may be provided for interconnecting the rear grooves with the polishing surface or the front grooves.

    摘要: A glass is irradiated with a focused pulsed laser beam having a peak power density of 10.sup.5 W/cm.sup.2 or more and a repetition rate of 10 KHz or more. The glass irradiated with the laser beam changes its refractive index at the focal point. During the laser beam irradiation, the glass is continuously moved with respect to the focal point of the pulsed laser beam or continuously scanned with the focused laser beam, so as to form the refractive index changed region (i.e. an optical waveguide) with a predetermined pattern. The glass in which the optical waveguide is formed may be any kind of glass having high transparency.

    摘要: A glass 1 is irradiated with a focused pulsed laser beam 2 having a peak power density of 10.sup.5 W/cm.sup.2 or more and a repetition rate of 10 KHz or more. The glass 1 irradiated with the laser beam 2 changes its refractive index at the focal point 4. During the laser beam irradiation, the glass 1 is continuously moved with respect to the focal point of the pulsed laser beam 2 or continuously scanned with the focused laser beam 2, so as to form the refractive index changed region (i.e. an optical waveguide 5) with a predetermined pattern. The glass 1 in which the optical waveguide 5 will be formed may be any kind of glass having high transparency.

The grooves may be formed in the polishing surface and/or the rear opposite surface of the pad and passages may be provided for interconnecting the rear grooves with the polishing surface or the front grooves. Grooves in the polishing surface may be provided with outlets through which a polishing slurry may flow while the polishing surface is in contact with a workpiece surface.
