  • Publication number: 20210319986
    Abstract: A plasma processing apparatus of an embodiment includes a chamber, an introducing part, a substrate electrode, a high-frequency power source, a low-frequency power source, and a switching mechanism. The introducing part introduces a process gas into the chamber. The substrate electrode is disposed in the chamber, a substrate is directly or indirectly mounted on the substrate electrode, and the substrate electrode includes a first and a second electrode elements alternately arranged. The high-frequency power source outputs a high-frequency voltage of 40 MHz or more for ionizing the process gas to generate plasma. The low-frequency power source outputs a low-frequency voltage of 20 MHz or less for introducing ions from the plasma. The switching mechanism applies the low-frequency voltage alternately to the first and the second electrode elements.

  • Patent number: 11139007
    Abstract: A semiconductor storage device includes a sense amplifier configured to read and program data in memory cells, a first latch circuit to store read data or program data, a second latch circuit to store the first data transferred from the first latch circuit or the second data before the second data is transferred into the first latch circuit, an input/output circuit to output the first data stored in the second latch circuit and to transfer the second data received thereby to the second latch circuit, and a control circuit. Upon receiving a read command while the control circuit is performing a program operation on program data stored in second latch circuit, the control circuit interrupts the program operation to perform the read operation and resumes the program operation on the program data in response to a resume write command sequence that does not include the program data.

  • Patent number: 10071444
    Abstract: A laser cladding apparatus includes a powder supplier to supply metal powder to a portion to be processed, a laser to irradiate the portion to be processed with laser so as to melt the metal powder for cladding, and a controller. The powder supplier includes a gas pressure gauge, and the controller stores, as an initial value, a gas pressure value measured by the gas pressure gauge when the metal powder supplied by the gas pressure reaches the portion to be cladding-processed. In operation after storing the initial value, the controller sets, as a reference time, timing when the gas pressure gauge measures a same pressure as the initial value, and outputs a start signal for laser irradiation to the laser based on the reference time.
