摘要： 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.

摘要： In order to prevent an erroneous determination of an on-film defect, the sensitivity of the post-inspection is reduced so that a film swelling due to a minute defect would not be detected. Classification is performed to determine whether a defect is at least one of an on-film defect and a film swelling, by performing a coordinate correction on the result of a post-inspection by an actual-defect fine alignment using the result of a pre-inspection performed with two-stage thresholds, and by checking defects against each other. In addition, classification is performed to determine whether a defect is at least one of an on-film defect and a film swelling by, during the post-inspection, preparing instruction data from information of the refractive index and thickness of a film formed on a wafer and comparing the instruction data with a signal intensity ratio of a detection system.

摘要： Since wires connected to a linear motor are routed in a vacuum sample chamber, outgassing is generated from wire coating and efficiency of assembly operations is reduced. Further, there is a problem that thrust generation efficiency of the linear motor is reduced when a gap between a coil and a permanent magnet of the linear motor cannot be small. In order to solve the above problems, a linear motor for vacuum is provided, the linear motor for vacuum including: a mover having a permanent magnet; and a stator having a support member to which a coil is fixed, in which the support member includes a vacuum sealing portion that vacuum seals with a wall surface of a vacuum sample chamber, and a feed-through for supplying a current to the coil provided in the vacuum sample chamber.
