  • Patent number: 11954842
    Abstract: The invention discloses a powder leakage monitoring device and a powder leakage monitoring method. The powder leakage monitoring device comprises light field camera, 3D PTZ (3-Dimensional Pan/Tilt/Zoom) and computer. Wherein, the light field camera records original light field images of monitored area; the 3D PTZ under the light field camera adjusts the shooting angle of the light field camera when it rotates according to the set direction; and the computer respectively connects to the light field camera and the 3D PTZ, which generates refocused images corresponding to the original light field images, and determines the spatial coordinates of the powder leakage point and the hazard range of the powder leakage in the monitored area according to the refocused images and the shooting angle. Therefore, the range and accuracy of powder leakage monitoring are both increased by using this invention.

  • Publication number: 20210398774
    Abstract: An etching device and method of inductively coupled plasma. The etching device of inductively coupled plasma includes an etching chamber, an excitation radio-frequency power supply, and a first bias radio-frequency power supply, and further includes a second bias radio-frequency power supply. The frequency of the second bias radio-frequency power supply is significantly lower than that of the first bias radio-frequency power supply. The etching rate and angle are controllable by means of the process of controlling distribution of ion energy by adjusting the radio-frequency bias of different frequencies, so as to adjust etching. In addition, since the mean free path of ions is larger, and the power utilization rate of etching is higher at the low pressure and low bias radio-frequency frequencies, rapid etching is achieved at relatively low power to implement green and energy-saving processing. The disclosure is applicable to the etching of magnetic tunnel junctions.
