  • Publication number: 20040036411
    Abstract: An organic EL display panel has a multi-layered structure in which a first electrode and a second electrode are formed on a transparent panel and an organic EL layer is formed between the first and second electrodes. A method for sealing the organic EL display panel includes the steps of forming a buffer layer of an organic matter such as silicon oxide and silicon nitride on the transparent panel, and locating a shield cover on the buffer layer. Thus, adhesive strength between the panel and an adhesive is enhanced to prevent external humidity and oxygen from being permeated into the panel, thereby increasing life span of the display.

  • Publication number: 20030148567
    Abstract: A poly-silicon (poly-Si) thin film transistor (TFT) having a back bias effect is provided in order to enhance characteristics of a leakage current, a sub-threshold slope, and an on-current. The poly-Si TFT includes a glass substrate, an island type buried electrode pad formed of an conductive material on one side of the glass substrate where the back bias voltage is applied, a buffer layer formed of an insulation material on the whole surface of the glass substrate, and a poly-Si TFT formed on the upper portion of the buffer layer. A method of fabricating the TFT is also provided.

  • Publication number: 20020056839
    Abstract: The present invention relates to a method of crystallizing an amorphous silicon thin film by thermal annealing the amorphous silicon thin film vapor deposited on a substrate in order to form a polycrystalline silicon thin film, and a semiconductor device fabricated by the method. According to the present invention, it is constructed such that a light-absorbing layer having absorbance of light much higher than that of the substrate or the amorphous silicon thin film is formed around the amorphous silicon thin film and is heated by a lamp when crystallizing the amorphous silicon thin film vapor deposited on the substrate by rapid annealing. Therefore, the temperature of the amorphous silicon thin film can be raised while restraining the increase in temperature of the substrate to the utmost. Accordingly, the amorphous silicon thin film can be crystallized without deformation of the substrate.
