Publication number: 20150001533Abstract: To provide a highly reliable semiconductor device including an oxide semiconductor. The device has a stacked-layer structure including an oxide semiconductor layer and an insulating layer in contact therewith. The oxide semiconductor layer includes a first layer where a channel is formed and a second layer which is between the first layer and the insulating layer and whose energy of the bottom of the conduction band is closer to the vacuum level than that of the first layer. The second layer serves as a barrier layer preventing formation of defect states between the channel and the insulating layer. The first layer and the second layer include a minute crystal part in which periodic atomic arrangement is not observed macroscopically or long-range order in atomic arrangement is not observed macroscopically. For example, a region with a size of 1 nm to 10 nm includes a crystal part having periodic atomic order.Type: ApplicationFiled: June 24, 2014Publication date: January 1, 2015Inventors: Hideaki Kuwabara, Yuta Endo, Mari Tateishi, Masahiro Takahashi
