  • Patent number: 12057067
    Abstract: Embodiments relate to a display device including pixels that compensate a threshold voltage of a driving transistor using the body effect. Pixel data for the driving transistor increases the source-bulk voltage of the driving transistor during a compensation period as a result of the body effect. A separate reference voltage is not received at the pixel for the purpose of compensating the threshold voltage of the driving transistor. The increased source-bulk voltage is then used in an emission period of the pixel to compensate for the threshold voltage of the driving transistor.

    Abstract: A thin film transistor array panel and a manufacturing method therefor. A shorting bar for connecting a thin film transistor with data lines is formed separate from the data lines, and then the data lines and the shorting bar are connected through a connecting member. As a result, all the data lines are floated during manufacture, so that variation in etching speed between data lines does not occur. Since variation in etching speed between the data lines can be prevented, performance deterioration of the transistor caused by a thickness difference in the lower layer of the data line can be prevented, as can resulting deterioration in display quality. Also, the influence of static electricity can be reduced or eliminated. Furthermore, since the data lines and the shorting bar are connected to each other, the generation of static electricity can be prevented or reduced, and quality testing is more readily performed.

  • Patent number: 8350269
    Abstract: Disclosed is a method of forming a semiconductor-on-insulator (SOI) structure on bulk semiconductor starting wafer. Parallel semiconductor bodies are formed at the top surface of the wafer. An insulator layer is deposited and recessed. Exposed upper portions of the semiconductor bodies are used as seed material for growing epitaxial layers of semiconductor material laterally over the insulator layer, thereby creating a semiconductor layer. This semiconductor layer can be used to form one or more SOI devices (e.g., single-fin or multi-fin MUGFET, multiple series-connected single-fin, multi-fin MUGFETs). However, placement of SOI device components in and/or on portions of the semiconductor layer should be predetermined to avoid locations which might impact device performance (e.g., placement of any FET gate on a semiconductor fin formed from the semiconductor layer can be predetermined to avoid interfaces between joined epitaxial semiconductor material sections).

  • Patent number: 8143118
    Abstract: A semiconductor device having a highly responsive thin film transistor (TFT) with low subthreshold swing and suppressed decrease in the on-state current and a manufacturing method thereof are demonstrated. The TFT of the present invention is characterized by its semiconductor layer where the thickness of the source region or the drain region is larger than that of the channel formation region. Manufacture of the TFT is readily achieved by the formation of an amorphous semiconductor layer on a projection portion and a depression portion, which is followed by subjecting the melting process of the semiconductor layer, resulting in the formation of a crystalline semiconductor layer having different thicknesses. Selective addition of impurity to the thick portion of the semiconductor layer provides a semiconductor layer in which the channel formation region is thinner than the source or drain region.
