摘要： To provide a transistor having a favorable electric characteristics and high reliability and a display device including the transistor. The transistor is a bottom-gate transistor formed using an oxide semiconductor for a channel region. An oxide semiconductor layer subjected to dehydration or dehydrogenation through heat treatment is used as an active layer. The active layer includes a first region of a superficial portion microcrystallized and a second region of the rest portion. By using the oxide semiconductor layer having such a structure, a change to an n-type, which is attributed to entry of moisture to the superficial portion or elimination of oxygen from the superficial portion, and generation of a parasitic channel can be suppressed. In addition, contact resistance between the oxide semiconductor layer and source and drain electrodes can be reduced.

摘要： A semiconductor device having a structure which enables sufficient reduction in parasitic capacitance is provided. In addition, the operation speed of thin film transistors in a driver circuit is improved. In a bottom-gate thin film transistor in which an oxide insulating layer is in contact with a channel formation region in an oxide semiconductor layer, a source electrode layer and a drain electrode layer are formed in such a manner that they do not overlap with a gate electrode layer. Thus, the distance between the gate electrode layer and the source electrode layer and between the gate electrode layer and the drain electrode layer are increased; accordingly, parasitic capacitance can be reduced.

摘要： In a channel protected thin film transistor in which a channel formation region is formed using an oxide semiconductor, an oxide semiconductor layer which is dehydrated or dehydrogenated by a heat treatment is used as an active layer, a crystal region including nanocrystals is included in a superficial portion in the channel formation region, and the rest portion is amorphous or is formed of a mixture of amorphousness/non-crystals and microcrystals, where an amorphous region is dotted with microcrystals. By using an oxide semiconductor layer having such a structure, a change to an n-type caused by entry of moisture or elimination of oxygen to or from the superficial portion and generation of a parasitic channel can be prevented and a contact resistance with a source and drain electrodes can be reduced.
