  • Patent number: 6773969
    Abstract: A gate of a thin film transistor (TM is formed on a surface of a substrate. A gate insulating (GI) layer and an amorphous silicon layer are then sequentially formed on the gate. A dehydrogen treatment is performed thereafter, and a re-crystallizing process is performed to transform the amorphous silicon layer into a crystalline silicon layer. Then, a doped n+ layer is formed on the gate, and portions of the doped n+ layer and the crystalline silicon layer are removed thereafter. Finally, a source and a gate of the thin film transistor are formed on the gate, and a passivation layer Is formed to cover the source and the gate.

  • Publication number: 20040009627
    Abstract: A method of preventing the cathode of an active matrix organic light emitting diode from breaking. A substrate having an array of thin film transistors thereon is provided. Each thin film transistor includes a gate electrode, a channel layer, a source terminal and a drain terminal. A passivation layer is formed over the substrate and then the passivation layer is planarized. Thereafter, an opening that exposes the drain terminal is formed in the passivation layer. An anode layer is formed over the passivation layer and the interior of a portion of the opening so that the drain terminal and the anode layer are electrically connected. A light-emitting layer and a cathode layer are sequentially formed over the substrate to form an active matrix organic light emitting device.
