  • Publication number: 20140291942
    Abstract: The present invention provides a chuck structure for substrate cleansing equipment, which comprises a base and at least a pair of clipping members. The pair of clipping members is disposed on both corresponding sides of the base, respectively. Each clipping member has a plurality of holes on a surface thereof. When the pair of clipping members moves towards the base, it clips a substrate such as a photomask, a wafer, or other semiconductor substrate. The surfaces of the clipping members having the plurality of holes are against the substrate for reducing the contact area between the clipping members and the substrate. Thereby, the static charges generated on the substrate by the friction between the clipping members and the substrate can be avoided, which can reduce the damages on the substrate due to electrostatic discharge effectively.

  • Publication number: 20130038866
    Abstract: The present invention is directed to a high speed, spinning chuck for use in a semiconductor wafer inspection system. The chuck of the present disclosure is configured with a turbulence-reducing lip. Spinning of the chuck produces radial airflows proximal to a surface of the wafer and proximal to the bottom of the chuck. The turbulence-reducing lip of the chuck of the present disclosure directs the radial airflows off of the top surface of the wafer and the bottom surface of the chuck in a manner that minimizes the size of the low pressure zone formed between these radial airflows. The minimization of the low pressure zone reduces air turbulence about the periphery of the chuck and substrate, thereby reducing the possibility of contaminants in the system being directed onto the surface of the substrate by such air turbulence.

    Abstract: The present invention discloses a self-locking mechanism for use in a drill chuck, comprising: clutch tooth sleeves, fixedly connected with the chuck body of the drill chuck and forming teeth; an oval deformation ring, having a substantially circular first shape and a substantially oval second shape, wherein the oval deformation ring has teeth on the side wall, with the teeth engaging with the teeth of the clutch tooth sleeve when the oval deformation ring is in the second shape; and a control sleeve, for controlling the conversion of the oval deformation sleeve between the first shape and the second shape. The present invention also discloses a force increasing self-locking drill chuck with said self-locking mechanism. The self-locking mechanism according to the present invention can be used in drill chucks of multiple structures, and provides a brand-new thought for the designs of the self-locking mechanisms of drill chucks.

  • Publication number: 20100038866
    Abstract: A system pendulum apparatus (13) is provided for a chuck and a method is provided for the clamping of workpieces with a pendulum element (16) and a basal element (30). An axially swivelable connection is provided between the pendulum element and the basal element by way of an element connection device. A swivel range a of the pendulum element can be restricted by a restriction device (39), and the pendulum element can be returned by a return device to a central position of the swivel range. The pendulum element can be fixed within the swivel range by a fixing device (23). The basal element can be joined by a joining device to one jaw of a chuck (10). The pendulum element has a clamping device with two exchangeable clamping elements (20), which are displaceable and fixable.
