  • Publication number: 20240068875
    Abstract: A thermopile sensor according to the present disclosure includes a p-type portion and an n-type portion. The p-type portion has a first phononic crystal in which first holes are arranged in a plan view. The n-type portion has a second phononic crystal in which second holes are arranged in a plan view. The p-type portion and the n-type portion constitute a thermocouple. The boundary scattering frequency of phonons in the first phononic crystal is different from the boundary scattering frequency of phonons in the second phononic crystal. Alternatively, the ratio of the sum of the areas of the first holes to the area of the first phononic crystal in a plan view is different from the ratio of the sum of the areas of the second holes to the area of the second phononic crystal in a plan view.

  • Patent number: 10061338
    Abstract: A semiconductor device for controlling a display device includes a generation unit configured to generate a reference voltage, a booster unit configured to boost the reference voltage to generate a bias voltage, and a conversion unit. The conversion unit receives a status signal generated from a power supply voltage and is configured to boost a voltage level of the status signal to that of the bias voltage for controlling drive of the display device. A control unit is configured to stop operation of at least one of the generation unit and the booster unit when one of a value of the power supply voltage and a value of a power supply current flowing from a power supply that generates the power supply voltage is lower than a predetermined threshold.
