Title: Shear force feedback structure capable of performing large area scanning, near-field optical microscope using the structure and its scanning method
Inventor: WEI PEI-KUEN
IPC: G02B26/00
Filed: 1998-09-09
Granted: 2000-07-01
Abstract: This is a shear force feedback structure using a probe for large area scanning, a near -field optical microscope with the shear force feedback structure is capable of performing large area scanning, and its scanning method. First, the probe's vibration angle is used as the feedback signal source and a cylindrical lens is used to replace a regular focusing lens such that a large area light field with a uniform distribution along the depth direction can be generated in the horizontal plane therefore the vibration angle measurement of the probe is not affected when the probe moves in the large-area light field in the horizontal plane. Therefore, when this probe proceeds with the scanning in the horizontal plane, it covers a relatively large scanning area. This new scanning-probe structure is applicable to any sample no matter it requires fixing or not. It is applicable to the near-field optical microscope and the scanning area can be as small as sub-micron and or as large as several millimeters, which is a relatively large dynamic scanning area.

Inventor: VANELL JAMES F
IPC: B24B37/04
Filed: 1998-10-29
Granted: 2000-03-01
Abstract: A chemical mechanical planarization tool that reduces a volume of polishing chemistry used in a wafer polishing process includes a rinse bar for removing polishing chemistry and particulates from a polishing media and a slurry measurement system for regulating a pump of a slurry delivery system. A volume of the slurry delivery system is reduced to less than 100 milliliters. Approximately a minimum volume of polishing chemistry for polishing a single wafer is dispensed during each wafer polishing process of a wafer lot. During each wafer polishing process the slurry delivery system is purged to prevent settling, agglomeration, and hardening of the polishing chemistry. The rinse bar sprays a surface of the polishing media to remove spent polishing chemistry and particulates prior to polishing another semiconductor wafer.

Title: Automatic defect classification with invariant core classes
Inventor: BEN-PORATH ARIEL
IPC: G01B15/00
Filed: 1999-05-28
Granted: 2005-01-11
Abstract: A method and apparatus is provided for automatically classifying a defect on the surface of a semiconductor wafer into one of, e.g., seven core classes: a missing pattern on the surface, an extra pattern on the surface, a deformed pattern on the surface, a particle on the surface, a particle embedded in the surface, a particle and a deformed pattern on the surface, or craters and microscratches on the surface. The defect may also be further classified into a subclass of arbitrarily defined defects defined by the user or preprogrammed in the apparatus. Embodiments include using a scanning electron microscope (SEM) capable of collecting electrons emitted from a plurality of angular sectors to obtain an image of the defect and a reference image containing topographical and location information, then analyzing this information to classify the defect. As the defects are classified, counts are maintained of the number of occurrences of each type of defect, and an alarm is raised if the defect count in a particular class exceeds a predetermined level. Thus, defects are accurately and reliably classified and monitored to enable early detection and cure of processing problems.

Title: Disc cartridge
Inventor: ICHIKAWA TORU
IPC: G11B17/04
Filed: 1999-06-11
Granted: 2001-05-28
Abstract: A disc cartridge generally comprises a data recording disc and a rectangular cassette for rotatably receiving therein the data recording disc. Elongate tracks are formed on laterally opposed side portions of an upper surface of the rectangular cassette. Each track is adapted to be pressed down by a pressing member when the disc cartridge is slid into a disc player. A plurality of parallel grooves are formed on the elongate tracks. With these parallel grooves, smoothed ingress and egress movement of the disc cartridge into and from the disc player is achieved while preventing undesired production of flaws or scratches on the elongate tracks which would be caused by a frictional sliding between the pressing member and the tracks. Even when fine particles or abrasion powder is produced due to the frictional sliding, such foreign particles are accumulated or collected in the grooves.

Title: Wristwatch with capacitive coupling
Inventor: BARRAS DAVID
IPC: G04G99/00
Filed: 1999-12-16
Granted: 2000-09-11
Abstract: The present invention concerns a wristwatch (30) including a case (32) provided with a first electric conductor (50) and an electric circuit (36) connected to said first electric conductor, and a wristband (34) including a second electric conductor (42). This wristwatch is characterised in that the first and second conductors are arranged to form an electric connection without any mechanical contact and, more precisely, by capacitive coupling. One advantage of such an arrangement of the wristwatch is that it achieves an electric connection without mechanical coupling, i.e. an electric connection which does not require any additional external maternal arrangement other than the conventional articulation between the wristband and the case.
