摘要： A thin-film transistor circuit, which is used as a driving circuit for driving pixels in an image display, is constituted of a plurality of thin-film transistors that are formed on an insulating substrate. In each thin-film transistor, a conductive electrode is placed so as to face a gate electrode with a channel region of a polycrystal silicon thin-film that forms an active layer located in between. Here, a constant voltage is applied to the conductive electrode. When threshold voltage is shifted by applying a voltage to the conductive electrode, it is possible to allow the absolute value of the threshold voltage of n-channel-type transistors and the absolute value of the threshold voltage of p-channel-type transistors to become virtually equal to each other. Moreover, it is possible to properly set the threshold voltage in accordance with factors such as the channel length of the thin-film transistors, the types of circuits that are constituted of the thin-film transistors and voltages to be applied to the thin-film transistors. Thus, it becomes possible to remarkably improve the characteristics of thin-film transistor circuits, such as operation speeds and holding characteristics.
摘要翻译：作为用于驱动图像显示中的像素的驱动电路的薄膜晶体管电路由形成在绝缘基板上的多个薄膜晶体管构成。在每个薄膜晶体管中，导电电极被放置成面对具有形成位于其间的有源层的多晶硅薄膜的沟道区的栅电极。这里，向导电电极施加恒定电压。当通过向导电电极施加电压来移动阈值电压时，可以允许n沟道型晶体管的阈值电压的绝对值和p沟道型晶体管的阈值电压的绝对值成为几乎相等。此外，可以根据诸如薄膜晶体管的沟道长度，由薄膜晶体管构成的电路的类型和施加到薄膜的电压等因素来适当地设置阈值电压晶体管。因此，可以显着提高诸如操作速度和保持特性的薄膜晶体管电路的特性。

摘要： An insulated gate transistor in which nitride oxide film having a nitrogen concentration of 1×1020 (/cm3) or more and containing a halogen element is used as a gate insulator. Because the gate insulator has a nitrogen concentration of 1×1020 (/cm3) or more, boron contained in the gate electrode of the p-type transistor is never diffused into the channel. Further because a halogen element is contained in the gate insulator, transistor conductance is increased and reliability in hot carrier injection is improved. Thus, an insulated gate transistor which has a sufficiently large conductance and which is superior in reliability can be fabricated.
摘要翻译：绝缘栅晶体管，其中氮浓度为1×10 20（/ cm 3）以上并含有卤素元素的氮氧化物膜用作栅极绝缘体。因为栅极绝缘体的氮浓度为1×10 20（/ cm 3）以上，所以p型晶体管的栅电极中所含的硼不会扩散到沟道中。此外，由于卤素元素包含在栅极绝缘体中，晶体管导通性增加，并且热载流子注入中的可靠性提高。因此，可以制造具有足够大电导且可靠性优异的绝缘栅晶体管。
