  • Publication number: 20150285627
    Abstract: The purpose of the present invention is to provide an overlay error measuring device which measures an overlay error with high accuracy even when a lower layer pattern is disposed under a thin film and a sufficient signal amount cannot be ensured. The present invention proposes an overlay error measuring device provided with an arithmetic processing unit for measuring a pattern formed on a sample on the basis of a signal waveform obtained by a charged particle beam device. The arithmetic processing unit finds a correlation with the signal waveform using a partial waveform obtained on the basis of partial extraction of the signal waveform, forms a correlation profile indicating the correlation, and measures an overlay error using the correlation profile.

  • Patent number: 8953855
    Abstract: An object of the present invention is to provide an edge detection technique and equipment which are capable of stably detecting an edge by suppressing the influence of noise even in the case where the image is obtained by charged particle radiation equipment, such as a scanning electron microscope and has a low S/N ratio. More specifically, the present invention is to propose a technique and equipment which are configured to determine a peak position (edge) on the basis of the following two edge extraction techniques. That is, the present invention is to propose a technique and equipment wherein at least two peaks are formed by using, as edge detection techniques, for example, one peak detection technique having a relatively high sensitivity and the other peak detection technique which is relatively less susceptible to the influence of noise than the one peak detection technique, and wherein a position where the peaks coincide with each other is determined as a true peak position (edge position).

  • Patent number: 8504833
    Abstract: A relay device first uses latest authentication data to determine whether request-authentication data transmitted from a wireless communications device is valid. If the latest authentication data is used to determine that the request-authentication data is valid, the relay device carries out relayed communications with the wireless communications device. If the latest authentication data is used to determine that the request-authentication data is invalid, the relay device next uses a former authentication data to determine whether the request-authentication data is valid. If the former authentication data is used to determine that the request-authentication data is valid, the relay device provides the wireless communications device with the latest authentication data to update authentication data in the wireless communications device.
