Patent attributes
The present invention provides a transistor having a high on-state current. The transistor includes a plurality of fins, a first oxide semiconductor, a gate insulating film, and a gate electrode. One of adjacent two fins includes a second oxide semiconductor and a third oxide semiconductor. The other includes a fourth oxide semiconductor and the third oxide semiconductor. The second oxide semiconductor and the fourth oxide semiconductor include regions that face each other with the gate electrode positioned therebetween. The gate electrode and the second oxide semiconductor overlap with each other with the gate insulating film and the first oxide semiconductor positioned therebetween. The gate electrode and the fourth oxide semiconductor overlap with each other with the gate insulating film and the first oxide semiconductor positioned therebetween.
