  • Publication number: 20040048559
    Abstract: Disclosed is a chemical mechanical polishing pad formed at a polishing surface thereof with micro-holes each having a desired cross-sectional area while having a desired depth. The shape, size, and density of the micro-holes can be optionally adjusted. The chemical mechanical polishing pad provides an effect of maintaining a desired polishing rate during a polishing process. In accordance with the present invention, the micro-holes can have diverse arrangements depending on given process conditions.

  • Publication number: 20030132207
    Abstract: Disclosed is a method for forming micro-holes, perforated holes, or grooves on a chemical mechanical polishing pad by a laser. This method involves the steps of determining a pattern of micro-holes, grooves, or perforated holes to be formed on a polishing pad, inputting the determined pattern to a computer numerical control (CNC) controller, and driving a laser device adapted to irradiate a laser beam and a table adapted to conduct a three-dimensional movement and rotation while supporting the polishing pad, under the control of the CNC controller based on the inputted pattern, thereby irradiating the laser beam from the laser device onto the polishing pad supported by the table while moving the table in accordance with the inputted pattern, so that micro-holes, grooves, or perforated holes having a pattern corresponding to the determined pattern are formed on the polishing pad.

  • Publication number: 20030058027
    Abstract: An output circuit of an integrated circuit device includes first and second MOS transistors including respective spaced apart pairs of source and drain regions in a substrate, arranged such that respective first and second channels of the first and second MOS transistors are laterally displaced with respect to one another. The output circuit further includes an isolation region in the substrate, disposed between the first and second MOS transistors. A first conductor connects the source region of the first MOS transistor to a power supply node. A second conductor connects the drain region of the first MOS transistor to the source region of the second MOS transistor. A third conductor connects the drain region of the second MOS transistor to an external signal pad of the integrated circuit device. The isolation region may comprise first and second insulation regions surrounding respective ones of the first and second MOS transistors, and a guard ring surrounding and separating the insulation regions.

  • Publication number: 20030034131
    Abstract: Disclosed is a chemical mechanical polishing pad formed at a polishing surface thereof with a plurality of concentric wave-shaped grooves having different radiuses while having the same shape. Each groove has a desired depth, width, and shape. The chemical mechanical polishing pad provides effects of effectively controlling a flow of slurry during a polishing process, thereby achieving a stability in the polishing process in terms of a polishing rate, and achieving an enhancement in the planarization of a wafer.

  • Patent number: 6377643
    Abstract: An apparatus for detecting a sync signal in a digital data record/replay device having a parallel clock generator, a parallel data generator, and a window unit comprises: a sync signal detector for comparing a pattern matching sync signal output from a sync pattern detector with an output signal of the window unit and detecting a sync signal according to clocks of the parallel clock generator; a latch unit for latching the sync signal detected by the sync signal detector and outputting the sync signal as a sync position signal according to clocks of the parallel clock generator; an identification error correction code (ID ECC) controller for generating an ID ECC control signal according to the sync position signal of the latch unit; an ID ECC decoder for decoding ID areas of parallel data generated by the parallel data generator; and a sync signal checking unit for outputting the sync position signal of the latch unit as a final sync signal and, when errors are detected as a result of the ID ECC decoding, sen

  • Patent number: 5293899
    Abstract: A fuel tank includes an inlet port communicating with a fuel decelerating section of the tank in which the inflowing fuel is decelerated. The decelerated fuel is delivered to a fuel intake compartment of the tank which contains a filter. The filtered fuel is then delivered to a fuel storage area of the tank which includes a hose leading to an outlet port. A buoyant member is mounted on the inlet end of the hose to enable that inlet end to rise to or near the surface of fuel in the tank. Sediment drains are provided in the bottom of the tank for removing sediment from the fuel intake compartment and the fuel storage area.
