  • Patent number: 11538671
    Abstract: In time-series data indicating light emission of plasma when plasma processing is carried out on a sample by generating the plasma, an analysis apparatus creates combinations of a plurality of light emission wavelengths of elements and a plurality of time intervals within a plasma processing interval and calculates, for each of the combinations of the wavelengths and the time intervals, a correlation between an average value of light emission intensity and the number of times the plasma processing is carried out on the samples for each of the combinations of the wavelengths and the time intervals that have been created. Thereafter, the data analysis apparatus selects, as a combination of the wavelength and the time interval used to observe or control the plasma processing, a combination of a wavelength of light emitting from a specific element and a specific time interval having a maximum correlation.

  • Publication number: 20210141567
    Abstract: A storage unit stores a memory access request to a DRAM. A deciding unit decides, based on a predetermined criteria, an issuance order of stored memory access requests. An issuance unit issues a command to the DRAM based on the decided issuance order. A determination unit, when the issuance unit issues a command of a first memory access request to the DRAM, selects, in accordance with the issuance order, a second memory access request that will next issue a command to the same bank as a bank where the first memory access request issues a command, and then determine whether the first and second memory access request target the same page. The issuance unit issues a command of the first memory access request without an auto precharge if determination unit determines that the same page is targeted.
