  • Publication number: 20240121373
    Abstract: Disclosed are an image display method and a 3d display system. The method is adapted to the 3d display system including a 3d display device and includes the following steps. A first image and a second image are obtained by splitting an input image according to a 3d image format. Whether the input image is a 3D format image complying with the 3D image format is determined through a stereo matching processing performed on the first image and the second image. An image interweaving process is enabled to be performed on the input image to generate an interweaving image in response to determining that the input image is the 3D format image complying with the 3D image format, and the interweaving image is displayed via the 3D display device.

  • Patent number: 8946003
    Abstract: A semiconductor transistor is formed as follows. A gate electrode is formed over but is insulated from a semiconductor body region. A first layer of insulating material is formed over the gate electrode and the semiconductor body region. A second layer of insulating material different from the first layer of insulating material is formed over the first layer of insulating material. Only the second layer of insulating material is etched to form spacers along the side-walls of the gate electrode. Impurities are implanted through the first layer of insulating material to form a source region and a drain region in the body region. A substantial portion of those portions of the first layer of insulting material extending over the source and drain regions is removed.

  • Patent number: 8288219
    Abstract: A stack of two polysilicon layers is formed over a semiconductor body region. A DDD implant is performed to form a DDD source region in the semiconductor body region along a source side of the polysilicon stack but not along a drain side of the polysilicon stack. Off-set spacers are formed along opposing side-walls of the polysilicon stack. A source/drain implant is performed to form a drain region in the semiconductor body region along the drain side of the polysilicon stack and to form a highly doped region within the DDD source region such that the extent of an overlap between the polysilicon stack and each of the drain region and the highly doped region is inversely dependent on a thickness of the off-set spacers, and a lateral spacing directly under the polysilicon stack between adjacent edges of the DDD source region and the highly doped region is directly dependent on the thickness of the off-set spacers.

  • Patent number: 7408212
    Abstract: An electrically programmable, non-volatile resistive memory includes an array of memory cells, a plurality of bit lines, and a plurality of word lines. Each memory cell comprises a resistive element and a Schottky diode coupled in series and having first and second terminals. Each bit line couples to the first terminal of all memory cells in a respective column of the array. Each word line couples to the second terminal of all memory cells in a respective row of the array. The resistive element for each memory cell may be formed with a film of a perovskite material (e.g., Pr0.7Ca0.3MnO3). The Schottky diode for each memory cell may be formed by a thin film of amorphous silicon. The films for the resistive element and Schottky diode for each memory cell may be stacked in a compact island at the cross point between a bit line and a word line.

  • Publication number: 20060252193
    Abstract: A semiconductor transistor which is not capable of storing data is formed as follows. An insulating layer is formed over a silicon region. An undoped polysilicon layer is formed over and in contact with the insulating layer.

  • Patent number: 6818504
    Abstract: Structures and methods for flash memory transistors are formed with self-aligned drain/source contacts. The flash transistors are formed with a plurality of gate layers. An etch resistant layer(s) are deposited on top of the gate layers in the memory array transistors and on the gate layers of peripheral transistors. An additional oxide layer/spacer may be formed on the etch resistant layer to control the resulting transistor junction configuration. As a result within the same process various transistors may be formed satisfying various requirements. Contact holes to the drain and source regions of the memory and peripheral transistors are then formed. The etch resistant layer prevents the contact etchants from completely etching away the protective etch resistant layer surrounding the gate layers. The spacing between the drain/source contacts and the gate layers can be greatly reduced increasing the density of the memory array transistors and reducing chip size.
