  • Publication number: 20240071722
    Abstract: Embodiments described herein relate to plasma processes. A plasma process includes generating a plasma containing negatively charged oxygen ions. A substrate is exposed to the plasma. The substrate is disposed on a pedestal while being exposed to the plasma. While exposing the substrate to the plasma, a negative direct current (DC) bias voltage is applied to the pedestal to repel the negatively charged oxygen ions from the substrate.

  • Patent number: 11914837
    Abstract: A video acquisition method, an electronic device, and a storage medium are disclosed. The video acquisition method is applicable to a virtual scene including at least one virtual object and at least one virtual camera. The terminal determines a target virtual object from the at least one virtual object in response to a camera capturing instruction triggered by a user on a virtual scene interface, controls the at least one virtual camera to capture the target virtual object to acquire capturing data of the target virtual object, and acquires the video of the target virtual object based on the capturing data.
