Abstract:
A semiconductor device with favorable electrical characteristics is to be provided. A highly reliable semiconductor device is to be provided. A semiconductor device with lower power consumption is to be provided. The semiconductor device includes a gate electrode, a first insulating layer over the gate electrode, a metal oxide layer over the first insulating layer, a pair of electrodes over the metal oxide layer, and a second insulating layer over the pair of electrodes. The first insulating layer includes a first region and a second region. The first region has a region being in contact with the metal oxide layer and containing more oxygen than the second region. The second region has a region containing more nitrogen than the first region. The metal oxide layer has at least a concentration gradient of oxygen in a thickness direction, and the concentration gradient becomes high on a first region side and on a second region side.

Claim (Index 11):
A method for manufacturing a semiconductor device comprising the steps of:\n forming a gate electrode; forming a first insulating layer over the gate electrode; adding oxygen in a vicinity of a surface of the first insulating layer; forming a metal oxide layer over the first insulating layer; forming a pair of electrodes over the metal oxide layer; and forming a second insulating layer over the pair of electrodes, wherein the step of forming the metal oxide layer is divided into a first step and a second step to deposit the metal oxide layer in vacuum through the first step and the second step conducted continuously, wherein the first step is conducted before the second step, and wherein the second step has a higher flow ratio of oxygen in a whole deposition gas than the first step.
