  • Publication number: 20110198686
    Abstract: A method for making a nitride read only memory device with buried diffusion spacers is disclosed. An oxide-nitride-oxide (ONO) layer is formed on top of a silicon substrate, and a polysilicon gate is formed over the ONO layer. The polysilicon gate is formed less than a length of the ONO layer. Two buried diffusion spacers are formed beside two sidewalls of the polysilicon gate and over the ONO layer. Two buried diffusion regions are implanted on the silicon substrate next to the two buried diffusion spacers. The two buried diffusion regions are then annealed such that the approximate interfaces of the buried diffusion regions are under the sidewalls of the polysilicon gate. The structure of a nitride read only memory device with buried diffusion spacers is also described.

    Abstract: Electronic device wafer level scale packages and fabrication methods thereof. A semiconductor wafer with a plurality of electronic devices formed thereon is provided. The semiconductor wafer is bonded with a supporting substrate. The back of the semiconductor substrate is thinned. A first trench is formed by etching the semiconductor exposing an inter-layered dielectric layer. An insulating layer is conformably deposited on the back of the semiconductor substrate. The insulating layer on the bottom of the first trench is removed to create a second trench. The insulating layer and the ILD layer are sequentially removed exposing part of a pair of contact pads. A conductive layer is conformably formed on the back of the semiconductor. After the conductive layer is patterned, the conductive layer and the contact pads construct an S-shaped connection. Next, an exterior connection and terminal contact pads are subsequently formed.

  • Publication number: 20110122296
    Abstract: An image deblurring system deblurs motion blurred images of a video stream captured from a moving object. An image deblurring method selects a blurred image from the video stream, selects blurred pixels from the blurred image, and calculates a movement offset for each of the blurred pixels according to coordinates of the blurred pixel in a frequency domain during the movement of the moving object. The method generates a point spread function according to the movement offset, and generates an image conversion formula according to the point spread function. The method converts each of the blurred pixels into a sharp pixel according to the image conversion formula, and generates a sharp image based on all of the sharp pixels.

  • Patent number: 7925999
    Abstract: A design method of printed circuit boards includes the following steps. First, simulate a printed circuit board including power layers, and vias connected to all the power layers. Then, change connections of the vias that tend to draw too much current to be connected to fewer power layers, than the vias that tend to draw less current. Repeat adjusting connections of the vias until all vias draw a similar amount of current such that no via draws more current than an upper limit the vias are designed for. Finally, according to the results, design/fabricate a PCB with vias respectively insulated, as needed, from the power layers that do not need to be connected to the vias.
