摘要： An infrared sensor formed as a membrane on a substrate and detecting infrared rays by an infrared detector on that membrane, wherein even if an adhesive used for mounting the infrared sensor on a mounting surface creeps up to the membrane, it is made possible to prevent a drop in the sensor sensitivity by mounting the infrared sensor on a mounting surface by an adhesive having a heat conductivity of not more than seven times the heat conductivity of a fluid present in the inner cavity below the membrane.

摘要： In a semiconductor sensor having a membrane structure, the destruction of the membrane caused by the expansion or contraction of a fluid within a hollow part formed under the membrane while the sensor is in use is prevented. A semiconductor sensor 10 comprising a substrate 30 and a membrane 20 formed on the top surface thereof, in which the bottom of the substrate 30 and a mounting surface 50 on which the sensor 10 is mounted are bonded, has pressure difference adjusting means 22a to 22c for eliminating the difference in pressure of a fluid between an inside and an outside of a hollow part 34 while the sensor is in use.

摘要： A capacitive humidity sensor includes a detection portion and a reference portion. The detection portion includes detection electrodes and a moisture sensitive film. The reference portion includes reference electrodes and a moisture permeation film as a capacitance adjusting film. The capacitive humidity sensor detects humidity by converting a capacitance difference between a capacitance of the detection electrodes and a capacitance of the reference electrodes to an electric signal by using a capacitance-voltage conversion circuit. The moisture permeation film reduces offset voltage of the capacitive humidity sensor. Thus, an offset compensation circuit or the like is not required.
摘要翻译：电容式湿度传感器包括检测部和参考部。检测部分包括检测电极和湿敏膜。参考部分包括参考电极和作为电容调整膜的透湿膜。电容式湿度传感器通过使用电容电压转换电路将检测电极的电容和参考电极的电容之间的电容差转换为电信号来检测湿度。透湿膜降低电容式湿度传感器的偏移电压。因此，不需要偏移补偿电路等。
