  • Patent number: 8247277
    Abstract: A manufacturing method of a thin film transistor is provided. An insulating pattern layer having at least one protrusion is formed on a substrate. At least one spacer and a plurality of amorphous semiconductor patterns separated from each other are formed on the insulating pattern layer. The spacer is formed at one side of the protrusion and connected between the amorphous semiconductor patterns. The spacer and the amorphous semiconductor patterns are crystallized. The protrusion and the insulating pattern layer below the spacer are removed so that a beam structure having a plurality of corners is formed and suspended over the substrate. A carrier tunneling layer, a carrier trapping layer and a carrier blocking layer are sequentially formed to compliantly wrap the corners of the beam structure. Hereafter, a gate is formed on the substrate to cover the beam structure and wrap the carrier blocking layer.

  • Publication number: 20100258808
    Abstract: A thin film transistor and a manufacturing method thereof are provided. A bottom gate, a gate insulating layer and an amorphous semiconductor layer are formed on a substrate. The amorphous semiconductor layer has an uneven upper surface. A laser annealing process is performed on the amorphous semiconductor layer through the uneven upper layer to transform the amorphous semiconductor layer into a polycrystalline semiconductor layer having a smaller-crystallizing-section and a greater-crystallizing-section. Another gate insulating layer, an upper gate and patterned photoresist layer are formed on the polycrystalline semiconductor layer. Patterns of the upper gate and the bottom gate are defined by the same photo-mask. A source/drain is formed in the polycrystalline semiconductor layer. An etching process with etching selectivity is performed on the upper gate and the patterned photoresist layer to make a length of the upper gate shorter than that of the bottom gate.

    Abstract: A thin film transistor (TFT) includes a poly-silicon island, a gate insulating layer, a gate stack layer, and a dielectric layer. The poly-silicon island includes a source region and a drain region. The gate insulating layer covers the poly-silicon island. The gate stack layer is disposed on the gate insulating layer and includes a first conductive layer and a second conductive layer. A length of the first conductive layer is less than a length of the second conductive layer. The dielectric layer covers the gate insulating layer and the gate stack layer, and therefore a number of cavities are formed between the second conductive layer and the gate insulating layer.

  • Patent number: 7411430
    Abstract: An analog output buffer circuit for a flat panel display is provided for improving an output signal distortion. The circuit includes a transistor, a current source, an input capacitor, an upper switch, a lower switch, a first switch, a second switch and a third switch. In which, the transistor and the current source are electrically connected in series between a first power supply and a second power supply. The current source provides a compensatory current for the transistor when a leakage current occurs. The upper switch and the first switch are turned on during the first period, and the lower switch and the second switch are turn on during the second period, in which the second period is after the first period. Those switches eliminate the drawback of different voltage levels between the input signal and the output signal obtained from the output buffer circuit inputted by the input signal.

  • Publication number: 20080171409
    Abstract: The present invention discloses a method for fabricating a bottom-gate low-temperature polysilicon thin film transistor, wherein the bottom gate structure is used to form an amorphous silicon layer with varied thicknesses; the amorphous silicon layer in the step region on the border of the bottom gate structure is partially melted by an appropriate amount of laser energy; the partially-melted amorphous silicon layer in the step region functions as crystal seeds and makes crystal grains grow toward the channel region where the amorphous silicon layer is fully melted, and the crystal grains are thus controlled to grow along the lateral direction to form a lateral-grain growth low-temperature polysilicon thin film. The lateral grain growth can reduce the number of the grain boundaries carriers have to pass through. Thus, the present invention can promote the carrier mobility in the active region and the electric performance.
