Semiconductor device |
| abstract |
A semiconductor device with sufficiently low off-state current is provided. An oxide semiconductor material whose effective mass of holes is heavier than that of electrons is used. A gate electrode layer on a substrate; a gate insulating layer; an oxide semiconductor layer having a heavy hole having an effective mass at least 5 times or more, preferably 10 times or more, more preferably 20 times or more compared to electrons; The transistor includes a source electrode layer in contact with the physical semiconductor layer and a drain electrode layer in contact with the oxide semiconductor layer.
