    摘要: An electrode formed using a transparent conductive oxide is likely to be crystallized by heat treatment performed in the manufacturing process of a semiconductor device. In the case of a thin film element using an electrode having a significantly uneven surface due to crystallization, a short circuit is likely to occur and thus reliability of the element is degraded. An object is to provide a light-transmitting conductive oxynitride which is not crystallized even if subjected to heat treatment and a manufacturing method thereof. It is found that an oxynitride containing indium, gallium, and zinc, to which hydrogen atoms are added as impurities, is a light-transmitting conductive film which is not crystallized even if heated at 350° C. and the object is achieved.

    摘要: An object is to provide a thin film transistor using an oxide semiconductor layer, in which contact resistance between the oxide semiconductor layer and source and drain electrode layers is reduced and electric characteristics are stabilized. Another object is to provide a method for manufacturing the thin film transistor. A thin film transistor using an oxide semiconductor layer is formed in such a manner that buffer layers having higher conductivity than the oxide semiconductor layer are formed over the oxide semiconductor layer, source and drain electrode layers are formed over the buffer layers, and the oxide semiconductor layer is electrically connected to the source and drain electrode layers with the buffer layers interposed therebetween. In addition, the buffer layers are subjected to reverse sputtering treatment and heat treatment in a nitrogen atmosphere, whereby the buffer layers having higher conductivity than the oxide semiconductor layer are obtained.

    摘要: The silicon nitride layer 910 formed by plasma CVD using a gas containing a hydrogen compound such as silane (SiH4) and ammonia (NH3) is provided on and in direct contact with the oxide semiconductor layer 905 used for the resistor 354, and the silicon nitride layer 910 is provided over the oxide semiconductor layer 906 used for the thin film transistor 355 with the silicon oxide layer 909 serving as a barrier layer interposed therebetween. Therefore, a higher concentration of hydrogen is introduced into the oxide semiconductor layer 905 than into the oxide semiconductor layer 906. As a result, the resistance of the oxide semiconductor layer 905 used for the resistor 354 is made lower than that of the oxide semiconductor layer 906 used for the thin film transistor 355.
