    • Provided are a structure and fabricating method of a new inverter for controlling a threshold voltage of each location when an inverter circuit is manufactured using an organic semiconductor on a plastic substrate.In general, p-type organic semiconductor is stable. Accordingly, when the inverter is formed of only the p-type semiconductor, a D-inverter composed of a depletion load and an enhancement driver has large gains, wide swing width and low power consumption, which is more preferable than an E-inverter composed of an enhancement load and an enhancement driver. However, it is impossible to form a depletion transistor and an enhancement transistor on the same substrate while controlling them by locations.To overcome such a difficulty, the structure of the inverter in which a bottom gate organic semiconductor transistor showing enhancement type characteristics is used as a driver transistor, and a top gate organic semiconductor transistor showing depletion type characteristics is used as a load transistor, and a manufacturing method thereof are proposed. According to this structure, a passivation effect of an organic semiconductor may be additionally obtained by a second insulating layer and a second gate electrode material which are on top of the organic semiconductor, and a high degree of integration may also be improved.
    • 提供了当在塑料基板上使用有机半导体制造逆变器电路时,用于控制每个位置的阈值电压的新型逆变器的结构和制造方法。 通常,p型有机半导体是稳定的。 因此,当逆变器仅由p型半导体构成时,由耗尽负载和增强型驱动器构成的D逆变器具有大的增益,宽的摆幅宽度和低功耗,这比组成的E型逆变器更优选 的增强负载和增强驱动器。 然而,不可能在相同的衬底上形成耗尽晶体管和增强晶体管,同时通过位置来控制它们。 为了克服这样的困难,将使用显示增强型特性的底栅有机半导体晶体管作为驱动晶体管的逆变器的结构和显示耗尽型特性的顶栅有机半导体晶体管用作负载晶体管,并且 提出了其制造方法。 根据该结构,可以通过位于有机半导体顶部的第二绝缘层和第二栅极电极材料另外获得有机半导体的钝化效果,并且还可以提高高集成度。

    • Provided is an inverter having a new structure capable of easily controlling a threshold voltage according to position in fabricating an inverter circuit on a plastic substrate using an organic semiconductor. A driver transistor is formed with a dual-gate structure and a positive bias voltage is applied to the top gate of the driver transistor so that a body effect appears in the organic semiconductor. Accordingly, the threshold voltage is shifted to a negative zone due to positive potential applied to the top gate of the driver transistor so that the driver transistor acts as an enhancement type transistor. A dual-gate organic structure may be applied to a load transistor rather than the driver transistor, or a p-type dual-gate organic transistor structure may be applied to both the driver transistor and the load transistor. Lifespan of the device can be increased, reliability of the device can be improved, and an organic inverter can be provided in which characteristics of organic electronic elements are easily adjusted according to circuit design even after the organic electronic elements are fabricated.
    • 提供一种逆变器,其具有能够根据使用有机半导体在塑料基板上制造逆变器电路时的位置容易地控制阈值电压的新结构。 驱动晶体管由双栅结构形成,正偏置电压施加到驱动晶体管的顶栅,从而在有机半导体中出现体效应。 因此,由于施加到驱动晶体管的顶栅极的正电位,阈值电压被转移到负区,使得驱动晶体管用作增强型晶体管。 双栅极有机结构可以施加到负载晶体管而不是驱动晶体管,或者p型双栅极有机晶体管结构可以施加到驱动晶体管和负载晶体管两者。 可以提高装置的寿命,可以提高装置的可靠性,并且可以提供有机逆变器,即使在有机电子元件制造之后,也可以根据电路设计容易地调整有机电子元件的特性。
