  • Patent number: 11923794
    Abstract: A motor control apparatus receives a DC power source through a DC terminal and is coupled to a motor. The motor control apparatus includes a brake, an inverter, and a controller. The brake is coupled to the inverter. The brake includes an energy-consuming component and a switch component. The controller controls the inverter to convert the DC power source to drive the motor. When the controller determines that the DC power source is interrupted, the controller stops controlling the inverter, and the switch component is self-driven turned on so that a back electromotive force generated by the motor is consumed through the energy-consuming component.

  • Publication number: 20230288820
    Abstract: Particulate deposition rate on a photolithographic mask, particularly of tin (Sn) particles produced within an EUV light source, is reduced by producing turbulence within a radiation source chamber of the EUV light source. Turbulence can be produced by changing the temperature, pressure, and/or gas flow rate within the radiation source chamber. The turbulence reduces the number of particles exiting the EUV light source which could be deposited on the photomask.
