  • Publication number: 20070259525
    Abstract: A CMP process is provided. A first polishing process on a wafer is performed using a first hard polishing pad with a first slurry. Then, a buffering process on the wafer is performed using a soft polishing pad with a cleaning agent to buffer the pH value in the first polishing process and to remove at least portion of the first slurry and the cleaning agent by the contact with the first soft polishing pad simultaneously. Thereafter, a second polishing process on the wafer is performed using a second hard polishing pad with a second slurry such that the pH value after the buffering process is between the pH value in the first polishing process and the pH value in the second polishing process. The method can avoid the scratch issue of wafer surface by particles resulting from pH shock and cross contamination.

  • Patent number: 7249739
    Abstract: A display stand comprises a connecting seat and supporting plate. A vertical guiding slot is disposed on said connecting seat. A rack and a control section are installed respectively at the two flank sides of the vertical guiding slot, in which the control section has a locking bar accepted in the slider, and one end thereof is engaged with the rack. After a panel is combined with connecting seat, said locking bar is driven to move along a single direction to be separated from the engagement of said rack by pulling the pull rod of the control section to push a skewed slot, and the slider is caused to slide up and down along the sliding slot by pulling said pull rod so as to change a relative angle between the connecting seat and the supporting plate. Finally, the pull rod is released to complete a positioning.

  • Publication number: 20070168566
    Abstract: A memory card with an indicator light has a casing, a processor, an input/output (I/O) interface, memory and an indicator light module. The indicator light module is mounted in the casing and connected to the I/O interface and has an inductor, an LED and a resistor. The inductor is connected to the I/O interface and has an input end and an output end. The LED is mounted on the casing and connected to the output end of the inductor. The resistor is connected in series with the LED. When the LED is not on, electrical power is not being provided to the proper pin on the I/O interface from the digital device. Consequently, any fault observed when the LED is not on can be attributed to a fault in the digital device.
