The displaceable measurement table, a mirror body carrying the measurement mirrors, and the receptacle for the substrate are embodied as separate components. The mirror body has a number of support points on its upper side and lower side for supporting a substrate or a receptacle above the upper side and for supporting the mirror body on the lower points above the measurement table. The mirror geometry is therefore unaffected by the weight of various substrates. The two measurement mirrors are integrated into a one-piece mirror body made of a material having an extremely low coefficient of thermal expansion. The described embodiments have frame-shaped openings in the X/Y coordinate measurement table and mirror body, which makes the measurement table suitable for both reflected and transmitted applications.

    Abstract: The invention relates to a holder for a semiconductor substrate including a main body which is provided with three or more projections by means of which the substrate can be held fixed in the holder. Two projections are fixedly connected, and a third projection present opposite the other two is movably connected to the main body. The third projection can be moved away from the other two and is urged towards the latter two by means. According to the invention, a lateral side of each projection facing towards the substrate to be inserted is provided with a convex recess whose geometry is such that exclusively the outermost edges of both the upper surface and the lower surface of the substrate to be inserted come into contact with the convex recess. A substrate, for example a round substrate, can be satisfactorily fastened in such a holder while still its entire surface area can be processed.

  • Patent number: 6279885
    Abstract: A magnetic clamp (20) for welding a magnetic object (504), includes a first magnetic member (22) and a second magnetic member (24). A hinge (26) connects magnetic members (22) and (24) so that an angle formed by magnetic members (22) and (24) may be changed. A spring loaded terminal (500) having a contact end (502) is disposed between first magnetic member (22) and second magnetic member (24). Magnetic clamp (20) may be attached to magnetic object (504) so that first magnetic member (22), second magnetic member (24), and contact end (502) all abut magnetic object (504). In a preferred embodiment, a removal tab (36) is connected to magnetic clamp (20) to assist in removing magnetic clamp (20) from magnetic object (504).

  • Patent number: 6241141
    Abstract: An improvement in a reflow soldering apparatus for bonding a connector element such as flexible circuitry or a pin type input/output (I/O) connector to a printed circuit board (PCB) is disclosed wherein a fixture tray included in the apparatus automatically aligns or self levels itself with the heating bars, or thermodes, of the apparatus. The fixture tray includes a body for supporting the connector/PCB assembly and cylindrical rods extending from the body. The rods are rotatably supported in corresponding grooves on the surface of the fixture tray table. As a thermode is pressed onto the connector/PCB assembly, the fixture tray rotates about its axis of rotation until the work area is aligned with the thermode. In a sandwich type soldering application including a pair of thermodes for simultaneously soldering opposite sides of a connector/PCB assembly, the fixture tray rests on an upper plate of a tray table supported by resilient means such as springs.

  • Patent number: 6237907
    Abstract: A method and apparatus for machining a radius or diameter defined feature at locations on a workpiece that are not symmetrically with respect to the workpiece boundaries, wherein the method employs a simplified and precise set up process which assures exact feature location; and the apparatus for implementing the method employs a dual jawed adjustable workpiece holder formed as a highly versatile V-block device wherein the V-point may be precisely shifted in vernier increments along both X and Y axes responsive to user input controlled translations of one or both adjustable jaws along parallel axes. A baseline method employs determining first and second distances from a feature central axis and first and second boundary points on the workpiece , and then using a 90 degree technique to first adjust the workpiece holder in translation and then adjust an adjustable V-block jaw.

  • Patent number: 6171400
    Abstract: An apparatus for holding a plurality of semiconductor wafers during heat treatment of the wafers in a furnace comprises a plurality of rails extending essentially vertically between a top and bottom plate. Each rail contains a plurality of teeth arranged such that the space between adjacent teeth can receive a portion of a single semiconductor wafer. Each tooth contains a raised support structure, typically a ledge, located on the top surface of each tooth for supporting the wafer, usually from the edge of the wafer inward to a point located from the center of the wafer a distance equal to between about 25% and about 75% of the wafer's radius. Such an apparatus with its relatively long teeth is especially designed to uniformly support larger wafers, i.e., wafers having a nominal diameter greater than about 200 millimeters, such that their own weight does not cause the wafers to sag and thereby produce crystal dislocations or slip when the wafers are heated to high temperatures.
