Granted: 2001-01-21
Abstract: The present invention relates to a method of producing a metal-based semiconductor circuit substrate. That is, the present invention provides a semiconductor circuit substrate that has improved properties: flat joins to connect external terminals, small variations in shape due to temperature changes, good mounting properties to a mother board, improved absorption efficiency of infrared rays during solder re-flowing, plating resistance and relatively high bonding reliability to other objects. Polyimide layers having special properties are laminated on the bottom surface of a metallic body of a metal-based semiconductor circuit substrate which has a polyimide layer used as an insulator. There are four lamination methods: (a) a method in which a layer of thermoplastic polyimide resin (1) and a layer of non-thermoplastic polyimide resin are sequentially laminated on the bottom surface of the metallic body, (b) a method in which a layer of thermoplastic polyimide resin (1), a layer of non-thermoplastic polyimide resin and a layer of thermoplastic polyimide resin (2) are sequentially laminated on the bottom surface of a metallic body, (c) a method in which a layer of non-thermoplastic polyimide resin is laminated on the bottom surface of a metallic body and (d) a method in which a layer of thermoplastic polyimide resin (2) is laminated on the bottom surface of a metallic body.

Title: Adaptive pulse width modulated motor control
Inventor: ROWAN BRYAN SCOTT
IPC: H02P25/02
Filed: 1998-06-30
Granted: 2001-07-11
Abstract: A motor control method and apparatus for spindle motor control and for voice coil motor (VCM) control in a direct access storage device (DASD). Characteristics of the pulse width modulation (PWM) waveform are adapted to allow tradeoffs to be made between lower noise emission greater power efficiency, and current ripple in the motor in order to optimize the driver operation. The transition rate of the PWM waveform is modified by changing the ""off-time"", which is maintained as a constant in a control register, in response to a change in the condition or mode of operation of the DASD. The ""slew rate"" of the PWM waveform is also controlled by a changing the value of a constant stored within the control register and can be modified in response to changes in the condition or operational mode of the DASD. In addition, in accordance with the present invention, the current that flows through the spindle motor windings during commutations is controlled by pulsing the power amplifier drive circuit at a relatively high rate in order to maintain a relatively constant total current through the windings of the motor, thus reducing acoustic noise. Thus, mechanical vibrations which result in acoustic noise are prevented or suppressed.

Patent TW-458947-B (TW)
Title: Apparatus and method for adding carbon dioxide gas to ultra pure water
Inventor: KATOU HITOSHI
IPC: C02F1/68
Filed: 1998-11-10
Granted: 2001-10-11
Abstract: A small flow of a water with a high carbon dioxide content (normally a carbon-dioxide-saturated water) is produced using hollow-fiber membranes, and is uniformly mixed with a large flow of untreated water with constant proportions. Since the hollow-fiber membrane module has a reserve capacity for adding carbon dioxide to the water, the resistivity of the mixed water is maintained at a constant level by maintaining constant proportions of the small and large flows, even if the total flow rate fluctuates due to fluctuations in the rate of water used in a subsequent process. Accordingly, no automated control device is particularly necessary in order to maintain the resistivity at a constant level. Therefore, a compact and simple apparatus can be produced which can operate at a low cost.

Title: Reflow chamber and process
Inventor: WANG HOU-GONG
IPC: H01L21/3205
Filed: 1999-02-23
Granted: 2002-01-01
Abstract: A method and apparatus for reflowing a material layer is provided. The inventive method introduces into a reflow chamber a material which is at least as reactive or more reactive than a material to be reflowed (i.e., a gettering material). Preferably the gettering material is sputter deposited within the reflow chamber while a shield prevents the gettering material from reaching the material layer to be reflowed. The shield may be coupled to, or integral with a clamp for clamping a wafer (containing the material layer to be reflowed) to a wafer support provided sufficient venting exists so that contaminants degassed from the wafer may flow to the region between the sputtering target and the shield where the contaminants can react with gettering material. The shield may have a roughened top surface (the surface that faces the sputtering target) which deters gettering material form flaking off the shield and/or the shield may have a reflective bottom surface (the surface that faces the wafer) that reflects heat to the wafer.

Abstract: The sewing error detection device for this invention is mounted and used on an overlock sewing machine, with which an over-edge chain stitch is made in a state in which a body fabric and a sleeve fabric of a T shirt or underwear are overlapped with each other. An uneven material feeding detecting sensor 12 for detecting whether or not material is fed unevenly by detecting the number of overlapping pieces of material to be sewn is set in a position corresponding to a sewing area sewn with a sewing machine needle 7, and in a position behind a needle location 6 along a sewing advancing direction Y, and the amount of uneven material feeding detected by the sensor 12 is compared with a preset allowable amount of uneven material feeding; if the amount of uneven material feeding detected exceeds the allowable amount of uneven material feeding, it is regarded as a sewing error and a report means 17 is operated. With this construction, a sewing error due to slip out even in performing a curve stitch can be detected reliably, and a variety of attachments, as required, can be mounted freely in front of the needle location.

Title: Projection lithography device utilizing charged particles
Inventor: KRIJN MARCELLINUS PETRUS CAROL
IPC: H01L21/027
Filed: 1999-09-23
Granted: 2001-12-11
Abstract: According to a known projection lithography method an object (14) is imaged on an imaging surface (16) by means of a telescopic system of rotationally symmetrical electron lenses (10, 12). The throughput during the production of integrated circuits by means of projection lithography is determined by the amount of current in the imaging electron beam; this current is subject to a limit which is imposed by the resolution-limiting interaction of the electrons (Coulomb interaction). The invention allows for a larger beam current in that areas (18) with a high current concentration are avoided. To this end, the imaging system includes two quadrupoles, each of which coincides with one of the two round lenses (10, 12), so that the electrons are concentrated in line-shaped focal spots instead of a (small) circular cross-over (18). The system remains telescopic to a high degree and the imaging remains stigmatic.

Filed: 1999-10-30
Granted: 2001-10-01
Abstract: The present invention is a switchable debugging device. A PCI bus signal monitor is first provided. The decoding address is adjusted based on the condition of the PCI bus signal monitored. The required decoding address is defined in a high-density type small package, such as FPGA, PGA, QFP, etc., and the setting can be modified in the running state; i.e., the decoding address can be varied anytime. Since the present invention provides two independent address match setting tools which can adjust the decoding address anytime, so as to not only detect two independent ports simultaneously, but also vary the required address without rebooting until the same address is set. Furthermore, each port has four switches; i.e., each port has at most 16 different addresses to be set, and thus there are at most 32 different addresses of the present invention to be set. Also, data from the PCI bus is latched and displayed on the display device (such as LED) for debugging.
