Definitions

  • a crystal boule indexing fixture comprising a frame including a pair of spaced apart, axially extending bores having parallel axes, and a pair of rods extending through the bores.
  • a cover is hingedly connected to the frame through a hinge pin having an axis parallel to the axis of the bores, the cover being movable between a first position overlying a portion of the rods to press a crystal boule against the rods and a second position to increase the spacing of the cover from the rods so as to permit entrance to and egress from the fixture of such a boule.
  • a lever projects from the cover and is biased so as to maintain the cover in its first position. Means are also provided to engage the lever to override the biased cover to lift the cover into the second position to facilitate entry and removal of the crystal boule.
  • One of the principal saws employed is of the type manufactured by Hamco Machine and Electronics Corporation, and is typified in US. Pat. No. 3,039,235 issued on June 19, 1962 to the aforementioned assignee.
  • the saw blade takes the form of a thin flat annulus which is provided with a cutting edge at the inner periphery of the annulus. The crystal is moved against the edge at a variable rate of movement to cut a thin slice from the crystal, and then the crystal is returned to the central portion of the annular cutting device, indexed downwardly a small increment, and the cycle is repeated.
  • Another object of the present invention is to provide a crystal boule indexing fixture which is readily adaptable to existing saws such as crystal slicing hole saws.
  • Still another object of the present invention is to provide a crystal boule indexing fixture which will hold the crystal rigidly to prevent lateral or radial displacement thereof as the crystal is being cut by the cutting blade, but which will permit indexing of the crystal longitudinally of the fixture so as to permit repetitive placement of the crystal in a predetermined position for cutting slices of semiconductor crystal of uniform thickness.
  • Yet another object of the present invention is to provide a crystal indexing fixture which may be easily oriented so as to permit cutting of the crystal along any desired crystallographic plane.
  • Still another object of the present invention is to provide a fixture having a cover thereon to clamp the crystal in a predetermined orientation relative to the machine while permitting ease of application of the cover to the boule and firm grasping of the boule while permitting the boule to be easily indexed.
  • FIG. 1 is a fragmentary front elevational view illustrating a crystal boule indexing fixture constructed in accordance with the present invention
  • FIG. 2 is a fragmentary side elevational view of the fixture illustrated in FIG. 1;
  • HG. 3 is a fragmentary bottom view of the apparatus illustrated in FIGS. 1 and 2.
  • the fixture 10 includes a frame 11 having a central body portion 12 and projecting flange portions 13 and 14 extending from the body 12.
  • the flange portions 13 and 14 include a pair of arcuate slots 13A and 14A respectively, which with bolts 15 and 16 serve to position the fixture 10 at a desired angle (in the plane of the paper) relative to a vertical axis, on the frame 17 of a cutting machine.
  • the body 12 of the frame 11 includes upper and lower pedestal portions 21 and 22 respectively each having a pair of spaced apart axially extending bores 23 and 24 therein, the bores having parallel axes and housing therein upstanding rods 25 and 26 respectively. As shown best in FIG.
  • each of the pedestals 21 and 22 includes a recessed portion 27 which permits the circumference or surface of the rods to project outwardly away from the pedestals so as to permit engagement thereof by the surface of the boule 20.
  • set screws 25A and 26A are utilized to grasp the rods to the body of the frame 11.
  • a quick release cover 30 is hingedly connected to the frame and movable between a first position overlying a portion of the rods to press a crystal boule against the rods and a second position to increase the spacing of the cover from the rods to permit entrance to and egress from the fixture of a crystal boule.
  • the cover 30 is generally arcuate in shape and subtends an angle of approximately 90 so that its terminal end 31 substantially overlies a plane drawn perpendicular to a line joining the axes of the rods and 26. In this manner the terminal end may capture the crystal boule 20 between the cover and the rods 25 and 26.
  • anti-torque means are provided on the cover to mate with means on the boule to inhibit rotation thereof.
  • a glass filled phenolic key 32 is bonded to the surface of the boule as with a semirigid epoxy, such as an Emerson Cummings EC-45 resin.
  • the key registers, mates or coopreates with a keyway 33 in the cover adjacent the terminal end 31 thereof.
  • the pedestals 21 and 22 include a projecting end portion having hinge pin 34 receiving apertures 29A and 29B therein, in the illustrated instance the apertures 298 in each of the pedestals 21 and 22 connecting, through the hinge pin 34 and bored bosses 35 and 36, the cover 30.
  • a handle 37 may be employed to facilitate grasping of the cover
  • quick acting clamp means are provided to facilitate moving of the cover between a first position overlying the rods and pressing a crystal boule between the cover and the rods and a second position wherein the cover is lifted away from the rods so as to facilitate loading of the fixture with a boule.
  • the sleeve 44 is provided with a groove 48 therein, while the bifurcated cam includes a bored hole 49 therein which permits the entry to and egress therefrom of a locking pin 50.
  • a dressing fixture 51 may be employed, the fixture including a block 52 connected to the flange 14 and dovetailed to receive a slide 53 thereon to which is connected a dressing stick 54 as by a ring clamp or the like 55.
  • the slide may have a mating dovetail as at 56 and include a rack gear which mates with a drive pinion 57 which permits elevation and depression of the dressing stick 54 towards and away from the blade 18 shown schematically in FIG. 1.
  • the dressing stick may be composed of any suitable dressing material, for example silicon carbide, and may easily be adjusted as to the ring clamp 55 merely by loosening the ring clamp and moving the stick downwardly as the stick is used.
  • a drive means 65 may be employed including a lead screw 66 or the like which is driven in a stepping fashion as by a stepping motor or an air drive, the lower end of the lead screw 66 abutting the crystal so as to effect axial displacement thereof along the guide rods between the cover and the guide rods.
  • the present invention provides a simple and yet novel crystal boule indexing fixture particularly adapted to existing saws.
  • a crystal boule indexing fixture comprising: a frame including a pair of spaced apart, axially extending bores having parallel axes; a pair of rods extending through said bores, a cover hingedly connected to said frame and movable between a first position overlying a portion of said rods to press a crystal boule against said rods and a second position to increase the spacing of said cover from said rods; a lever projecting from said cover and means biasing said lever to maintain said cover in said first position; and anti-torque means on said cover to mate with means on a crystal boule to inhibit rotation thereof, said anti-torque means comprising one of a key and key-way, and said means on a crystal boule comprising the other of said key and key-way; and means to engage said lever to over-ride said biasing means to lift said cover into said second position.
