Title: Method of precisely accessing and placing chip to align the substrate during flip chip bonding process
Inventor: HUANG JUNG-TANG
IPC: H01L21/68
Filed: 2000-10-26
Granted: 2002-02-21
Abstract: The present invention relates to a method for precisely accessing and placing chip to align the substrate. In the proposed method, instead of directly bonding the chip bump to the pad of substrate after a chip is accurately aligned to the substrate, industrial video camera (CCD) is shifted to the corner of the chip in order to obtain the image of chip corner and the periphery of the corresponding substrate or the positioning mark. After the image is recorded, industrial video camera is moved out to let the chip (it can be the substrate depending on different condition of each apparatus) shift to a position such that there is a separation distance about 20 μm (the separation distance can be designed by oneself depending on different requirements) between the substrate and the chip before they contact each other. The industrial video camera is shifted to the corner position again, in which a correlation comparison between image obtained presently and previous image of corner position is performed such that the chip is not bonded to the base board until the comparison value is higher than the value defined in advance. Because the remaining distance is only 20 <mu>m when bonding process is finally conducted, the deviation amount can reach a very small value such that the precision can be greatly increased.

Title: Metal chemical mechanical polishing process for minimizing dishing during semiconductor wafer fabrication
Inventor: LIN CHENTING
IPC: B24B37/04
Filed: 2001-05-11
Granted: 2005-11-01
Abstract: A two-step chemical mechanical polishing (CMP) process is provided to minimize (reduce) dishing of metal lines in trenches in an insulation (oxide) layer of each of a plurality of semiconductor wafers during fabrication thereof. For each wafer, the first step involves CMP of a metal layer disposed on the oxide layer and having a lower portion located in the trenches for forming metal lines and an upper portion overlying the lower portion. The first step polishing uses a first polishing pad to remove the bulk of the metal layer upper portion while generating concomitant CMP residue, and leaves a minimized (reduced) remainder of the metal layer upper portion without dishing of the metal layer lower portion in the trenches. The second step continues the CMP with a second polishing pad to remove the remainder of the metal layer upper portion with minimized (reduced) dishing of the metal layer lower portion to an extent providing the metal lines as individual metal lines in the trenches. Each wafer undergoes the first step polishing with the first polishing pad and then the second step polishing with the second polishing pad. The second polishing pad has at most a deficient content of prior accumulated concomitant CMP residue, e.g., is a relatively fresh (clean) polishing pad.

Granted: 2002-08-21
Abstract: The subject of this invention is to continuously generate superfine air bubbles of the order of 0.5-3 μm with a simple constitution of device. The solution of this invention is as follows. Air is sucked from the outside by utilizing a negative pressure generated at the time of activating a centrifugal pump and a gas-liquid mixture 23 between the air and bath water is produced. The gas-liquid mixture 23 is sent to a static type mixer 13 and is further stirred and mixed by the static type mixer 13, and the super-fined gas-liquid mixture 27 is produced. The static type mixer 13 is composed of a screw part 25 on the upstream side and a cutter part 26 on the downstream side. The screw part 25 is composed of a cylindrical main body 28, a partition rod 29 which is disposed on a shaft center part of the main body 28 and a spiral vane 30 which is disposed in an annular passage between the main body 28 and the partition rod 29. The cutter part 26 is composed of the cylindrical main body 31 and plural projections 32 which are disposed on the inner peripheral surface of the main body. The gas-liquid mixture 23 becomes a swirling stream when passing the screw part 25, the swirling stream comes into collision with a projection 32 of the cutter part 26 and, therefore, the superfine air bubbles of the order of 0.5-3 μm can be continuously generated.

Title: Shaft transmission
Inventor: POEHLAU FRANK
IPC: F16H49/00
Filed: 2001-05-23
Granted: 2003-05-11
Abstract: To be able to guide supply or structural elements centrally through a shaft transmission, it is designed as a hollow gear. Such a shaft transmission directly supplies a translators correcting variable defined and preset by means of the number of revolutions of its drive ring and thus of the motor-driven shaft generator, if the power take-off ring axially displaces a threaded rod engaged by means of the rotational movement of its inner thread and extending freely coaxially through a central longitudinal bore in the shaft transmission, because this is secured against rotation by being integral with the housing. The linear movement of the threaded rod relative to the drive motor can occur with a fixed installed transmission motor just as much as it can with a fixed installed threaded rod.

Title: Multiple output dynamically regulated charge pump power converter
Inventor: NEBRIGIC DRAGAN DANILO
IPC: H02M3/07
Filed: 2001-08-22
Granted: 2003-05-21
Abstract: A charge pump power converter efficiently provides electrical power by dynamically controlling a switch matrix of the charge pump. Instead of open-loop oscillator-based control, a dynamic controller provides power upon demand by sensing the output voltage and changing the operating frequency of the charge pump in response. Moreover, this closed-loop dynamic control intrinsically voltage regulates the output voltage of the charge pump power converter without the inefficient addition of a step-down voltage regulator, downstream of the power converter. Additional efficiencies are achieved through maintaining the voltage ripple across the fly capacitor and/or the load capacitor. Also, a three-state control scheme is used to charge the fly capacitor, wait for the output voltage to drop to a predetermined level, and discharge the fly capacitor. Furthermore, a multiple-output charge pump power converter provides multiple voltage levels for devices such as portable communication electronic devices.

Title: Digital start control method of liquid crystal display and apparatus
Inventor: SUEN JENG-YUN
IPC: G09G3/20
Filed: 2001-10-05
Granted: 2003-02-21
Abstract: The present invention discloses a digital start control method of liquid crystal display (LCD) and apparatus. In the invention, a timing power source controller is used to control multi sets of power source switches of LCD. The timing power source controller uses timing signals to sequentially trigger ON/OFF for each set of power source. Each one of trigger timings has constant delay time for turning on/off multiple sets of power sources so as to provide accurate turning-on and turning-off sequence. Therefore, the invention is capable of effectively avoiding the drawbacks of non-smooth turning-on and turning-off due to the erroneous switching sequence caused by noise interference in controlling the start of multiple sets of power sources in the conventional analog type LCD.

Title: Method and apparatus for measuring and orienting golf club shaft
Inventor: WEISS RICHARD M
IPC: A63B53/10
Filed: 2001-11-09
Granted: 2006-06-11
Abstract: The preferred orientation, or planar oscillation plane, of a golf club shaft is located by measuring the oscillation of the shaft when an impulse is applied. Preferably, the out-of-plane oscillation is measured at a large number of angular positions about the shaft axis, and the principal planar oscillation plane is identified by that pair of opposed angular positions in which the out-of-plane oscillation is smallest. The location of the preferred orientation may be marked on the shaft and used to assemble a golf club with the planar oscillation plane in a predetermined orientation. The straightness of the shaft can also be determined by deriving its spring constant from its oscillation frequency and then measuring the restoring force when the shaft is deflected by the same nominal amount at different angular positions; differences in restoring force can be attributed to differences in actual deflection distance resulting from lack of straightness.
