Title: Modular wafer polishing apparatus and method
Inventor: ANDERSON H ALEXANDER
IPC: B24B37/04
Filed: 1998-12-21
Granted: 2000-01-21
Abstract: A wafer polishing apparatus includes a module frame; a continuous belt rotatable with respect to the frame, the belt having at least one vertically-oriented belt transverse portion including a polishing pad assembly; and at least one pivotable wafer-holding head drive within the frame and having a distal end portion movable to a vertical first position parallel and juxtaposed to the belt transverse portion. The head drive includes a wafer carrier for holding a wafer on the distal end portion of the head drive, while a drive moves the distal end portion and a held wafer into a vertical polishing position abutting the belt transverse portion. Pressure is applied to the held-wafer against the polishing pad assembly while the wafer-holding distal end portion is rotated and swept side-by -side. After polishing the drive is reversed and the head drive is pivoted away from the belt transverse portion to a horizontal or other orientation and the then polished wafer removed. Multiple modules may be placed end-to-end or side-by -side with a robot pathway therebetween to load unpolished wafers and to unload polished wafers to a buffing station, to a cassette or other processing station.

Title: Integrated circuit test systems that use direct current signals and impedance elements to improve test signal transmission speed and reduce test signal distortion
Inventor: KIM JAE-HEE
IPC: G11C29/48
Filed: 1999-08-23
Granted: 2002-02-11
Abstract: Integrated circuit test systems include an input driver having an output terminal that is connected to a test system port and a biasing device that is connected between the test system port and a reference voltage. The biasing device comprises a Thevenin equivalent circuit that is represented by an impedance element and a non-zero power source. The impedance element may be used to match the impedance of a device under test, which can reduce distortion in signals passed between the device under test and the test system. Furthermore, the power source may be used to provide direct current (DC) signals at the pins of a device under test, which can allow the swing height (e.g., amplitude or magnitude) of the test signals to be reduced. That is, the test signals are superimposed upon the DC voltages to allow ""high"" and ""low"" logic levels to be manifested via relatively minor swings in the test signals. By reducing the swing height of the test signals, transmission speed can be improved thereby reducing round trip signal delay.

Title: Melt level detector and detection method
Inventor: MORIYA MASATO
IPC: C30B29/06
Filed: 2000-03-16
Granted: 2001-07-11
Abstract: To provide a melt level detector capable of simply and precisely detecting a melt level and also to provide a melt level detection method using the detector. The detection method using this detector for detecting the melt level of a melt surface in a CZ (Czochralski) furnace on the basis of the principle of triangulation, comprises: moving the projection position on the melt surface of a laser beam irradiator in the radial direction of a crucible 14 in the CZ furnace to scan such a projection position that the laser beam 2 reflected from the melt surface is received by a laser beam receiver; and setting the projection position of the laser beam 2 to this position. Thus, since an appropriate melt surface part for detecting a melt level is found by scanning the projection angle within a very narrow range and measurement of the melt level is performed in this appropriate part, complication of the detector can be avoided and the detection of the melt level is performed in such a state that the influence of noise caused in the melt surface on the detection is reduced.
