Inventor: BAJAJ RAJEEV
IPC: B24B37/34
Filed: 2000-04-25
Granted: 2001-07-21
Abstract: A selective damascene chemical mechanical polishing (CMP) technique is used to planarize a semiconductor device to remove surface topography. The semiconductor device includes a semiconductor layer formed on a substrate, an insulating layer formed over the semiconductor layer and patterned to expose a portion of the semiconductor layer, a barrier layer formed over the insulating layer and the exposed portion of the semiconductor layer, and an electrically conductive layer formed over the barrier layer. The semiconductor device is pressed against a first rotating polishing pad that has no embedded abrasive particles to remove a portion of the conductive layer that overlies both the barrier layer and the insulating layer. The semiconductor device is then pressed against a second rotating polishing pad that has embedded abrasive particles to expose a portion of the barrier layer that overlies the insulating layer. The device is then pressed against a third rotating polishing pad that has no embedded abrasive particles to remove the portion of the barrier layer that overlies the insulating layer.

Title: Semiconductor device, and method for manufacturing the same
Inventor: BABA SHINJI
IPC: H01L21/56
Filed: 2000-05-08
Granted: 2003-03-21
Abstract: A semiconductor device which ensures high packaging reliability and maintains high power/ground plane characteristics and can be embodied inexpensively even when the device has a large number of terminals, as well as to provide a method of manufacturing the semiconductor device. Since the reliability of mounting of the solder balls 9 can be improved even when the system board 16 is of great size, there can be embodied a BGA-type semiconductor device having terminals in the number of 700 to 1000 pins or more, thus eliminating a necessity for mounting sockets, which would be required in the case of a PGA-type semiconductor device and contributing to a decrease in costs. Further, even when the number of terminal pins is increased further, since the signal terminals can be arranged in a full-matrix pattern with a high degree of freedom, the semiconductor chip 2 can be made compact. The bumps 3 formed between the semiconductor chip 2 and the BGA substrate 1 have high reliability, and hence a multi-pin semiconductor device can be embodied inexpensively.

Granted: 2003-04-21
Abstract: The present invention is related to a process where a polycrystalline silicon layer with a thickness of 0.1-1.6 μm is formed on the rear surface of the silicon wafer by chemical vapor deposition (CVD) method and oxygen concentration of a silicon wafer, with which crystal oriented particles (COPs) and interstitial-type large dislocations (L/Ds) are not produced on a wafer surface is not larger than 1.2x10<SP>18</SP> atoms/cm<SP>3</SP> (old ASTM). The above silicon wafer is subjected to a thermal treatment at 1,000 DEG C ± 30 DEG C for 2-5 hours in an oxygen atmosphere, and successively, is subjected to a thermal treatment at 1,130 DEG C ± 30 DEGC for 1-16 hours. More specifically, oxidation induced stacking faults (OSFs) are made obvious in the central part of the silicon wafer. Therefore, when a conventional thermal treatment for making OSF obvious is carried out, the polycrystalline silicon wafer produced through above mentioned method is free of OSF and COP. It makes oxide deposited uniformly over the whole surface of the wafer and obtains uniform gettering effects, without variation between the circumferential edge and central part of the wafer.

Title: Direct forming of non-textile fabric elements from thermoplastic pellets or the like
Inventor: O'CONNOR GREGORY W
IPC: D06N3/00
Filed: 2000-10-27
Granted: 2002-02-21
Abstract: An inventive solid phase forming process, and related structure, using conventional pelletized thermoplastic compositions to form the elements of a non-textile fabric by coining a single pellet or briquette of the polymer into an individual element in a single forming step. The steps of the process generally include: (a) positioning a pellet in or adjacent to a mold cavity, and (b) forcing the pellet into contact with the mold surfaces of the mold cavity to plastically deform the pellet to cause the pellet to adapt the shape of the mold cavity. The mold cavity has a shape to form the desired element, and its volume is substantially the same as the volume of the pellet. The forcing step or act preferably uses an energy and speed wherein the pellet superplastically deforms to substantially fill the volume of the mold cavity. This process is repeated with the particular element being formed in the appropriate order to form interconnected plates and rivets, as an example, with the final result being a non-textile fabric. The elements formed by the inventive process can have any of a variety of shapes, and can form base units for the formation of the non-textile fabric of two, three or more elements. This inventive process eliminates the need to first form the pelletized polymer into a sheet or other type of preform prior to the forming of the final product.

Granted: 2003-09-21
Abstract: The present focusing method is used in a focus detecting apparatus comprising an objective lens, means for entering a luminous flux for focus detection into a target object from a position inconsistent with an optical axis of the objective lens through at least the objective lens, a condenser lens for converging the luminous flux after it is reflected by the target object and again passes through the objective lens, two two-division sensors disposed with the same optical inclination in front of and behind a position where the reflected luminous flux is converged by the condenser lens when a focus of the objective lens is adjusted to the surface of the target object, and a signal processing circuit for performing operational processing of signals from the two two-division sensors. The focus detecting apparatus detects whether the focus of the objective lens is adjusted to the surface of the target object. When focusing is performed with this apparatus, the target object is moved while the focus position is followed after the detection of the focus position, focus detection is performed many times and the detected signal values are averaged, and the resultant average value is used to drive the objective lens. This series of operations is repeated, and then the focus position is fixed.

Title: Improvements in electrical vehicles
Inventor: BROOKS DAVID MICHAEL
IPC: B60L5/00
Filed: 2001-06-18
Granted: 2004-11-21
Abstract: A method for controlling connection of a transformer of an electric vehicle, such as a train locomotive, to an alternating voltage supply carried by a trolley wire, the object being to reduce the transformer inrush current on connection of the transformer to the supply. The method comprises the steps of judiciously controlling movement of a pantograph of the vehicle from its lowered position to a raised position so that as the pantograph approaches the trolley wire, an arc bridges the air gap between them to consistently connect the electrical transformer of the vehicle to the trolley wire when the voltage present on the wire is at or near its peak. Furthermore, the vehicle's power system is controlled such that if the power supply to the trolley wire is lost while the pantograph is raised, the transformer is first isolated from the pantograph and then after the power supply is restored, the pantograph is lowered, re-connected to the transformer and re-raised to re-establish the connection with the trolley wire in the above judiciously controlled manner.

IPC: H01L21/768
Filed: 2001-11-13
Granted: 2002-11-01
Abstract: This invention discloses a manufacture method of copper interconnects. Firstly, a dielectric layer containing via holes is formed on a substrate. Then, a barrier layer and a copper seed layer for plating are formed sequentially on the inner surface of the via holes. An electrochemical reduction reaction is carried out on the copper seed layer to in-situ remove the oxide layer on the surface of the copper seed layer with an applied predetermined voltage of -0.3 to 0 volt, in which the predetermined voltage uses a silver/silver-chloride as a reference electrode. Finally, a copper plated layer is formed on the copper seed layer by plating to completely fill the via holes and thus form interconnects containing no copper oxide layer. Therefore, reliability and yield of the interconnect are enhanced.
