| 7137865 | Method and device for cutting single crystals, in addition to an adjusting device and a test method for determining a crystal orientation A method for the division of single crystals, in particular of GaAs, is provided in which a single crystal (1) to be cut into at least two parts and a cutting tool (2, 3; 8, 8a, 8b, 8c) are moved relative to one anoth... | 11/21/2006 |
| 6827072 | Dressing wheel and method of making same A dressing wheel has a disk-shaped base body centered on an axis and formed with an annular groove also centered on the axis and having an inner surface. A multiplicity of abrasive elements distributed along the groove are in direct contact with the groove inner sur... | 12/07/2004 |
| 6390889 | Holding strip for a semiconductor ingot A holding strip is used to hold a semiconductor ingot during semiconductor wafer fabrication. The holding strip is formed from a semiconductor material, typically the same material used to form the ingot itself. The holding strip has a holding surface sha... | 05/21/2002 |
| 6286499 | Method of cutting and separating a bent board into individual small divisions Disclosed is an improved method of cutting and separating a bent board into individual small divisions. Prior to the cutting and separating of the board into the individual chips the board is cut and separated into two or more pieces each large enough to ... | 09/11/2001 |
| 6257224 | Process for working a preform made of an oxide single crystal, and a process for producing functional devices A process for dicing a preform made of an oxide single crystal into cut pieces each having a given shape, includes the steps of removing molecules of the oxide single crystal through dissociation and evaporation with an optochemical reaction under irradia... | 07/10/2001 |
| 5287843 | Slicing machine employing an axial force to provide rigidity to a rotary blade A slicing machine for slicing an ingot using a rotary blade that maintains the inner peripheral cutting edge of the blade in a highly rigid state. The slicing machine slices the ingot into thin pieces by use of an inner peripheral cutting edge of a doughn... | 02/22/1994 |
| 5174270 | Slicing machine and a slicing method by the same A slicing method includes slicing an ingot by a rotary blade while the inner peripheral cutting edge of the blade is kept in a highly rigid state. A slicing machine slices the ingot into thin pieces by use of an inner peripheral cutting edge of a doughnut... | 12/29/1992 |
| 5135727 | Automatic single crystal ingot disconnector for single crystal pulling apparatus An automatic single crystal ingot disconnector which is mounted on the uppermost chuck of the conventional single crystal ingot removing assembly, which uppermost chuck assembly is adapted to shift in the axial direction of the ingot being chucked; the pr... | 08/04/1992 |
