  • Patent number: 6899592
    Abstract: In a polishing apparatus, a polishing tool including abrasive particles and a binder for bonding together the abrasive particles is pressed against a substrate to polish the substrate. The polishing apparatus has a light source for irradiating a polishing surface with light rays for weakening a bond force of the binder for bonding together the abrasive particles, and a waste matter removing mechanism for forcefully removing waste matter produced by polishing or waste matter produced by irradiation. By irradiating the polishing surface with the light rays, dressing of the polishing surface is performed, and products resulting from dressing and the like are removed. The polishing apparatus supplies abrasive particles to the polishing surface stably by dressing and allows high-speed polishing of the substrate.

  • Patent number: 6889581
    Abstract: A wrench including a stem having a head section at one end of the stem and a polygonal socket formed in the head section for fitting onto a screwed member. A resilient ring is disposed at the head section and pivotally connected with a controlling switch pivotally disposed at the head section. By means of operating the controlling switch, the resilient ring is driven to expand or close. In the closed position, the resilient ring obstructs at least one inner angle of the socket to prevent the screwed member from detaching out of the socket and clamp the screwed member in the socket. In the expanded position, the resilient ring frees the inner angle, permitting the screwed member to freely pass through the socket.

  • Patent number: 6871570
    Abstract: An improved ratchet or gear wrench that has a built-in, non-slip, gripping clip mechanism for retaining a nut in the tool, which can either be applied to the nut or clamped out-of-the-way. This tool allows a nut to be tightened or loosened from a bolt or threaded stud more quickly and with one hand. To attain this, the present invention essentially comprises a spring-loaded curveshaped gripping clip, mounted near the boxed-end of a ratchet wrench, which wraps around the opening of the wrench. The spring action of the gripping clip allows it to be easily pulled away from the opening of the wrench and clamped in an out-of-the-way position by means of a clamp or released into a functional gripping position by pushing downward on the clamp's release button. When released, the gripping clip presses against a nut, thereby creating pressure that secures the nut in the opening of the wrench.

  • Patent number: 6592434
    Abstract: A wafer carrier (300) for a CMP tool is adjustable to provide center fast to edge fast material removal from a semiconductor wafer. The wafer carrier (300) holds the semiconductor wafer without vacuum. The semiconductor wafer is held by a carrier ring (308). An elastically flexed wafer support structure (318) is a support surface for the semiconductor wafer. Elastically flexed wafer support structure (318) can be bowed outward or bowed inward in an infinite number of different contours. The semiconductor wafer conforms to the contour of the elastically flexed wafer support structure (318) when a down force is applied to the wafer carrier (300) during a polishing process. Changing the contour is used to produce different material removal rates across the radius of the semiconductor wafer to increase wafer planarity in a polishing process.
