SEMICONDUCTOR DEVICE AND ELECTRONIC APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide a transistor having high and stable electric characteristics even though a structure is fine; or achieve high performance and high reliability even in a semiconductor device including the transistor.SOLUTION: A semiconductor device has on a substrate, a conductor, an oxide semiconductor and an insulator. The oxide semiconductor has a first region and a second region, in which the second region has resistance lower than that of the first region and a whole area of the oxide semiconductor to be the first region is surrounded by the conductor via the insulator.SELECTED DRAWING: Figure 1
