    Abstract: A method of packaging an organic electroluminescent (OEL) device is provided. In the method, a substrate comprising an OEL component formed thereon is provided first. Thereafter, a cover plate is provided. Afterward, a hydrophilic polymer serving as a desiccant between the substrate and the cover plate is formed. Then, an adhesive between the substrate and the cover plate for sealing the OEL component and the desiccant is formed. Therefore, moisture/oxygen in the package structure is absorbed and removed by the hydrophilic polymer.

  • Publication number: 20070114604
    Abstract: A MOS transistor structure is disclosed. A gate electrode is disposed on a semiconductor substrate. A first extension of a predetermined impurity type is substantially aligned with the gate electrode in the substrate. A second extension of the predetermined impurity type overlaps with the first extension in the substrate. The first extension has at least one lateral boundary line closer to the gate electrode than that of the second extension. Source and drain regions of the predetermined polarity type overlaps with the first and second extensions in the substrate. The second extension has at least one lateral boundary line closer to the gate electrode than that of the source and drain regions. The source and drain regions are deeper than the second extension, which is deeper than the first extension, so that they collectively reduce lateral abruptness of the source and drain, while maintaining a reduced extension resistance.

  • Publication number: 20040082089
    Abstract: An organic light-emitting device having a porous desiccant layer therein and a method for fabricating the same is provided. The porous desiccant layer is manufactured by spreading a liquid desiccant on a surface, forming air bubbles (by activating some vesicant or injecting gas into the liquid desiccant) and curing the liquid desiccant. The porous desiccant comprises solidified hardening glue having bubbles and lots of desiccant particles or powder distributed evenly therein. Some residual vesicant may remain inside the solidified hardening glue after activation. The bubbles inside the porous desiccant enhance the absorption rate and efficiency of the desiccant so that moisture and gaseous oxygen inside the OLED package can be absorbed rapidly.

  • Publication number: 20030094660
    Abstract: A semiconductor structure having silicon dioxide layers of different thicknesses is fabricated by forming a sacrificial silicon dioxide layer on the surface of a substrate; implanting nitrogen ions through the sacrificial silicon dioxide layer into first areas of the semiconductor substrate; implanting chlorine and/or bromine ions through the sacrificial silicon dioxide layer into second areas of the semiconductor substrate where silicon dioxide having the highest thickness is to be formed; removing the sacrificial silicon dioxide layer; and then growing a layer of silicon dioxide on the surface of the semiconductor substrate. The growth rate of the silicon dioxide will be faster in the areas containing the chlorine and/or bromine ions and therefore the silicon dioxide layer will be thicker in those regions as compared to the silicon dioxide layer in the regions not containing the chlorine and/or bromine ions.
