  • Publication number: 20240069524
    Abstract: Disclosed is an apparatus for excitation signal generation for a resolver. The apparatus includes a sine wave generator that generates a sine wave based on a square wave, an amplifier that amplifies the sine wave, a differential signal generator that converts, into a differential signal, the amplified sine wave, a driver that inputs the differential signal to a coil, and a processor that generates an excitation signal by increasing a voltage of the sine wave from a start voltage to a target voltage through at least one of the sine wave generator and the amplifier based on a transient current that flows into the coil in a transient response interval.

  • Publication number: 20240071791
    Abstract: A method of manufacturing a semiconductor device may comprise loading a first substrate and a second substrate into a substrate processing apparatus, wherein the first substrate is loaded into a first chamber and the second substrate is loaded into a second chamber on the first chamber, and processing the loaded first substrate and the loaded second substrate, wherein the substrate processing apparatus comprises, the first and second chambers, a first pipe through which a first processing solution supplied to the first chamber to process the first substrate is moved, a second pipe through which a second processing solution supplied to the second chamber to process the second substrate is moved, and a temperature adjusting pipe configured to surround at least a part of the first pipe, through which the temperature adjusting solution adjusting a temperature of the first processing solution is moved, wherein a length of the first pipe is shorter than a length of the second pipe.

  • Publication number: 20230024625
    Abstract: An aluminum nitride sintered body contains 1 to 5% by weight of yttrium oxide (Y2O3), 10 to 100 ppm by weight of titanium (Ti), and the balance being aluminum nitride (AlN). Accordingly, a volume resistance value and thermal conductivity at a high temperature are improved, and the generation of impurities during a semiconductor manufacturing process can be suppressed.
