The sound generating chip is capable of playing a message, a song, or any other type of sound recording. The sound transducer converts the electrical signal from the sound generating chip into an audible sound. The sound generating chip is powered through the battery. The switch controls the electrical power supplied to the sound generating chip. The sound generating chip, sound transducer, battery, and spring switch are contained in the housing. One end of a pull device is withdrawn from the switch to enable electrical power to be supplied to said sound generating chip to emit audible sound through the sound transducer.Type: ApplicationFiled: September 9, 2002Publication date: March 20, 2003Inventor: Arthur W. Piepenbrink

Publication number: 20030054729Abstract: Methods and apparatuses for electromechanically and/or electrochemically-mechanically removing conductive material from a microelectronic substrate. An apparatus in accordance with one embodiment includes a support member configured to releasably carry a microelectronic substrate and first and second electrodes spaced apart from each other and from the microelectronic substrate. A polishing medium is positioned between the electrodes and the support member and has a polishing surface positioned to contact the microelectronic substrate. At least a portion of the first and second electrodes can be recessed from the polishing surface. A liquid, such as an electrolytic liquid, can be provided in the recess, for example, through flow passages in the electrodes and/or the polishing medium. A variable electrical signal is passed from at least one of the electrodes, through the electrolyte and to the microelectronic substrate to remove material from the substrate.Type: ApplicationFiled: August 29, 2002Publication date: March 20, 2003Inventors: Whonchee Lee, Scott E. Moore, Scott G. Meikle

Publication number: 20030054730Abstract: A cover to be disposed over a substrate processing apparatus is provided. The cover includes a material capable of being tuned between an opaque state and a transparent state. Being tuned closer to the opaque state limits an amount of light capable of passing through the tunable cover and into the substrate processing apparatus during substrate processing. Being tuned closer to the transparent state allows viewing into the substrate processing apparatus without removing the cover.Type: ApplicationFiled: September 3, 2002Publication date: March 20, 2003Applicant: Lam Research Corp.Inventors: Helmuth W. Treichel, Julia S. Svirchevski, Mike Ravkin

Publication number: 20030054731Abstract: A grinding wheel and a method for grinding bar blade for the production of spiral gear teeth are described. For economical grinding of such bar blades the grinding wheel has a conical grinding surface (Pp) widening from a small diameter (d1) to a large diameter (d2), a cylindrical grinding surface (Ps) adjoining the conical grinding surface (Pp), and a toroidal grinding surface (G) adjoining the cylindrical grinding surface (Ps). The grinding wheel embodied in this manner enables profile grinding (rough grinding) and subsequent generating grinding (finish grinding) of the surfaces of the bar blade without the necessity of remounting the blade. For practical purposes the grinding wheel rotates about a stationary axis (S), and the bar blade to be ground is guided along the grinding wheel [(12)] at appropriately set angles.Type: ApplicationFiled: September 26, 2002Publication date: March 20, 2003Inventors: Horia Giurgiumann, Manfred Knaden

Publication number: 20030054732Abstract: A method of manufacturing aluminum frames for photomask protective films comprises the step of: providing a square-shaped hollow or solid strut aluminum material, fastening the bottom end of the aluminum material to a base of a machine tool, using a milling cutter to fabricate and form a hollow trough for a selected depth in the aluminum material from the top surface thereof, and using a cutting tool to cut off the aluminum material at the periphery of the hollow trough to form individual aluminum frames for the photomask protective films. The method of the invention uses fewer chucks and screw bolts during machining, and can reduce chuck setup time and simplify machining processes.Type: ApplicationFiled: September 20, 2001Publication date: March 20, 2003Applicant: Gudeng Precision Industrial Co., Ltd.Inventor: Ming-Chien Chiu

Publication number: 20030054733Abstract: A process of dry polishing molded or lathe cut intraocular lenses or like medical devices to removing flash, sharp edges and/or surface irregularities therefrom. The process includes gas and/or rotational tumbling of the intraocular lenses or like medical devices in a dry polishing media. The process is suitable for single piece and multipiece intraocular lenses of varying composition.Type: ApplicationFiled: August 9, 2002Publication date: March 20, 2003Inventors: Madhu Ayyagari, Mahendra P. Nandu

Publication number: 20030054734Abstract: A method and system for separating impurities, such as large abrasive particles and foreign matter from an abrasive polishing slurry prior to a Chemical Mechanical Polishing (CMP) procedure performed on a surface of a semiconductor wafer. Impurities greater than about 25 microns are removed by an initial filtration process. The filtrate is then introduced to a solid bowl, sedimentation-type centrifuge to remove particles greater than 0.5 microns thereby providing a polishing slurry for final utilization in a CMP procedure that reduces damage to the surface of the polished semiconductor wafer.Type: ApplicationFiled: September 17, 2001Publication date: March 20, 2003Inventors: William Mullee, Glenn Jankins, Michael Jones

Publication number: 20030054735Abstract: An improved polishing pad (22) for use in a chemical mechanical polishing (CMP) operation as part of a semiconductor device fabrication process. The polishing pad is formed of a plurality of particles of abrasive material (24) disposed in a matrix material (26). The abrasive particles may be a stiff inorganic material coated with a coupling agent, and the matrix material may be a polymeric material such as polyurethane. As the polishing pad wears through repeated polishing operations, the newly exposed polishing surface will contain fresh abrasive particles and will exhibit the same polishing properties as the original surface, thereby providing consistent polishing performance throughout the life of the pad without the need for conditioning operations. In one embodiment the distribution of particles of abrasive material per unit volume of matrix material may vary from one portion (23) of the pad to another (25).Type: ApplicationFiled: September 17, 2001Publication date: March 20, 2003Inventors: Sudhanshu Misra, Pradip Kumar Roy

Publication number: 20030054736Abstract: The circumferential edges of glass or ceramic disks used in disk drive data storage devices are preferably finished by ductile grinding to produce an essentially fracture-free surface, which is not chemically strengthened. Preferably, the material is glass, and both the inner and outer edges of the disk are finished. Edge finishing is preferably achieved in a two-stage process, involving a coarse grind and a ductile grind, using air bearing spindles rotated at high speed for grinding wheels and workpiece. Preferably, the grinding wheels are shaped to provide a radius at the juncture of the circumferential edges and flat disk surfaces.Type: ApplicationFiled: September 17, 2001Publication date: March 20, 2003Applicant: International Business Machines CorporationInventors: James A.
