IPC: H03K19/096
Filed: 2020-03-16
Abstract: To reduce circuit scale of a semiconductor device, or to improve drive capability of the semiconductor device.SOLUTION: A transistor with a channel region formed of oxide semiconductor is used as pull-down transistor. The oxide semiconductor has a bandgap of 2.0 eV or more, preferably 2.5 eV or more, more preferably 3.0 eV or more. Therefore, hot carrier deterioration in the transistor can be suppressed. Thus, circuit scale of a semiconductor device with the pull-down transistor can be reduced. A gate of the pull-up transistor is put into a floating state by switching of the transistor. Higher purity of the oxide semiconductor can provide transistor off-current of 1aA/μm(1×10-18A/μm) or less. As a result, the drive capability of the semiconductor device can be improved.SELECTED DRAWING: Figure 1
