  • Publication number: 20080029877
    Abstract: The present invention provides a semiconductor device package singulation method. The method comprises printing a photo epoxy layer on the back surface of a substrate of a wafer for marking the scribe lines to be diced. Then etching is performed through the substrate along the marks in the photo epoxy layer. Dicing the panel into individual package with a typical art designing knife, the step not only avoids the roughness on the edge of each die, but also decrease the cost of singulation process.

  • Patent number: 7313068
    Abstract: An apparatus and method for automatic power control is disclosed. An optical recording apparatus utilizes a low-speed, peak-hold circuit to obtain and output a maximum of a front photodiode output signal during a predetermined window or plurality of windows of a total duration long enough to allow maximum peak-hold signal to stabilize. After stabilization, the maximum peak-hold signal is sampled and held in a sample and hold circuit. A reset then clears the signal and reinitializes the peak-hold circuit. In accordance with the difference between a reference voltage and the held peak-hold signal, a feedback controller unit outputs the required current level into a driving unit for producing desired recording pulses into a laser diode for recording information pits into an optical disc. A calibration gain may be used when, due to insufficient FPD response speed, the held signal is different than the real optical power output.

  • Patent number: 7262999
    Abstract: An ultra cycling nitride read only memory (NROM) device is coupled to a NROM array such that both bits of the ultra cycling NROM device will be erased when all NROM devices of the NROM array are erased. The ultra cycling NROM device is then programmed at its right bit. A threshold voltage difference will be obtained for the ultra cycling NROM device for the un-programmed left bit. Next, a cycling number is obtained based on the threshold voltage difference for the ultra cycling NROM device. A threshold voltage shift can be found based on the cycling number for the NROM array. Finally, an erase voltage will be calculated according to the threshold voltage shift for the NROM array. If the NROM array is programmed again, the erase voltage will be applied to un-programmed NROM devices of the NROM array to further reduce the threshold voltages.

  • Publication number: 20070176558
    Abstract: The invention discloses a plasma display panel (PDP). The PDP grounds an exposed transparent conductive layer to the inner component thereof, so as to shield off electromagnetic interference (EMI). Accordingly, there is no metal structure in the second protective layer formed on the transparent conductive layer, such that the second protective layer can be easily attached onto the transparent conductive layer. Therefore, the manufacturing of PDP is getting much easier, and the yield rate will then increase.
