    • A temperature sensor includes first and second lower electrodes, a ferroelectric layer having polarization, a semiconductor layer; and first to third upper electrodes. The second upper electrode is interposed between the first upper electrode and the third upper electrode in a plan view. The semiconductor layer includes a first channel disposed between the first upper electrode and the second upper electrode, and a second channel disposed between the second upper electrode and the third upper electrode. The ferroelectric layer includes a first ferroelectric part disposed below the first channel and a second ferroelectric part disposed below the second channel. A polarization direction of the first ferroelectric part is opposite to a polarization direction of the second first ferroelectric part. The temperature is calculated based on the output voltage from the second upper electrode and the voltage applied to the first upper electrode.
    • 温度传感器包括第一和第二下部电极,具有极化的铁电体层,半导体层; 和第一至第三上电极。 第二上电极在平面图中插入在第一上电极和第三上电极之间。 半导体层包括设置在第一上电极和第二上电极之间的第一通道和设置在第二上电极和第三上电极之间的第二通道。 铁电层包括设置在第一通道下方的第一铁电体部分和设置在第二通道下方的第二铁电体部分。 第一铁电体部的偏振方向与第二第一强电介质部的偏振方向相反。 基于来自第二上电极的输出电压和施加到第一上电极的电压来计算温度。
