  • Patent number: 7638374
    Abstract: A method of fabricating a vertical thin film transistor (vertical TFT) is disclosed, wherein a shadow mask is used to fabricate the TFT device in vertical structure. First, a metal layer is formed, which serves as ribs and a gate layer. Next, a shadow mask is disposed on the gate layer. Afterwards, the shadow mask is used as a mask to form a source layer, an organic semiconductor layer and a drain layer. Thus, the process is simplified. Since no photolithography process is required, and therefore damage of the organic semiconductor layer is avoided and a vertical TFT with desired electrical characteristics may be obtained.

  • Publication number: 20090237608
    Abstract: A spacer structure of a display panel includes a first substrate, a second substrate, a spacer, and a spacer pad. The spacer is disposed on a side of the first substrate facing the second substrate, and the spacer pad is disposed between the second substrate and the spacer. The spacer pad has a non-linear structure lodged in the spacer, and therefore restrains the spacer from moving with respect to the second substrate in the plane parallel to the surface of the second substrate.

  • Patent number: 7379341
    Abstract: A method of performing a power on sequence for a flash memory includes applying device voltage to the flash memory and loading nonvolatile memory data and nonvolatile memory complementary data to a read data register and a read complementary data register, respectively. The nonvolatile memory data and the nonvolatile memory complementary data are compared with the read data register and the read complementary data register during the power on sequence, e.g., after initial power up or power on reset (POR). When the comparison determines a mismatch, the loading of the nonvolatile memory data and the nonvolatile memory complementary data to the read data register and the read complementary data register, respectively, is repeated.

  • Publication number: 20080102567
    Abstract: A method for making a thin film transistor (TFT) is provided. A mask is first formed on the backside of a substrate, and is used to fabricate a gate, source, and drain of the transistor by backside exposure, such that the source and drain can be self-aligned with the gate pattern. In this way, an alignment shift due to expansion or contraction after performing a high temperature process on an insulating layer can be avoided. Further, since the backside mask previously formed on the substrate can be shifted with the expansion or contraction of the substrate, the process is simplified. Moreover, the source/drain can be accurately aligned with the gate, so that parasitic capacitance can be reduced and flickering of the panel can be avoided.
