  • Publication number: 20240068124
    Abstract: An apparatus for producing silicon carbide crystal is provided and includes a composite structure formed by a plurality of graphite layers and silicon carbide seed crystals, wherein a density or thickness of each layer of graphite is gradually adjusted to reduce a difference of a thermal expansion coefficient and Young's modulus between the graphite layers and silicon carbide. The composite structure can be stabilized on a top portion or an upper cover of a crucible made of graphite, thereby preventing the silicon carbide crystal from falling off.

  • Patent number: 11619753
    Abstract: The disclosure provides a processing circuit adapted to read out a sensing voltage of an X-ray sensor and a signal processing method of a sampling circuit. The processing circuit includes an amplifier and the sampling circuit. An inverting input terminal of the amplifier is coupled to the X-ray sensor. The sampling circuit is coupled to an output terminal of the amplifier. The sampling circuit obtains a first voltage, a second voltage, and a sampling voltage of the X-ray sensor in different periods. The sampling voltage is between the first voltage and the second voltage. In the readout period, the sampling circuit subtracts the second voltage from the sampling voltage to obtain a third voltage, subtracts the second voltage from the first voltage to obtain a fourth voltage, and divides the third voltage by the fourth voltage to read out the sensing voltage of the X-ray sensor.
